Pain Behind the Knee: Causes and Treatment by Dr. Mayur Rabhadiya

Understanding Pain, Tightness or Swelling Behind the Knee

Pain behind the knee, also called posterior knee pain, may arise from the knee joint, menisci, muscles, tendons, a fluid-filled Baker’s cyst or less commonly a blood vessel or nerve-related condition.

Patients may describe:

  • A dull ache behind the knee

  • Tightness while bending

  • Pain when straightening the leg

  • A lump or fullness behind the knee

  • Swelling extending into the calf

  • Pain after walking

  • Discomfort while climbing stairs

  • Pain after running

  • A pulling sensation

  • Stiffness after sitting

  • Pain after knee surgery

  • Night pain

  • Difficulty bearing weight

The location of symptoms provides useful clues, but it does not establish the diagnosis by itself.

A patient with a soft lump and arthritis-related swelling may have a different problem from someone who develops sudden calf pain and one-sided leg swelling.

Dr. Mayur Rabhadiya is an Orthopedic & Joint Replacement Surgeon in Mumbai with a focused clinical practice in knee pain, knee arthritis, joint preservation and knee replacement surgery.

Quick Answer: What Causes Pain Behind the Knee?

Common causes include:

  • Baker’s cyst or popliteal cyst

  • Knee osteoarthritis with excess joint fluid

  • Meniscal injury or degeneration

  • Hamstring tendon irritation

  • Calf or gastrocnemius muscle injury

  • Popliteus muscle or tendon irritation

  • Ligament injury

  • Joint swelling

  • Previous knee surgery

  • Pain referred from the hip or spine

Less commonly, pain and swelling behind the knee may be associated with a blood clot or another vascular condition.

Treatment depends on the underlying cause.

Simply draining a cyst or taking repeated pain medication may provide temporary relief without correcting the condition producing the symptoms.

Structures Located Behind the Knee

The area behind the knee is called the popliteal region.

Structures in and around this area include:

  • Posterior joint capsule

  • Medial and lateral menisci

  • Hamstring tendons

  • Gastrocnemius muscle

  • Popliteus muscle and tendon

  • Cruciate ligaments

  • Blood vessels

  • Nerves

  • Fat and connective tissue

  • Bursa and potential cyst spaces

Because important joint, muscular, neurological and vascular structures lie close together, posterior knee pain requires a careful history and examination.

Common Causes of Pain Behind the Knee

Baker’s Cyst or Popliteal Cyst

A Baker’s cyst is a fluid-filled swelling behind the knee.

It commonly develops when a problem inside the knee causes excess joint fluid.

Associated conditions may include:

  • Knee osteoarthritis

  • Rheumatoid or inflammatory arthritis

  • Meniscal injury

  • ACL injury

  • Joint inflammation

  • Other internal knee conditions

The excess fluid may move toward the back of the knee and form a cyst-like swelling.

Symptoms may include:

  • Fullness behind the knee

  • A visible or palpable lump

  • Tightness

  • Pain while bending

  • Pain while straightening

  • Knee stiffness

  • Swelling around the knee

  • Reduced movement

  • Calf discomfort if the cyst leaks or ruptures

Some Baker’s cysts cause minimal symptoms and are found incidentally.

The size of a cyst does not always correspond directly to the severity of symptoms.

Does a Baker’s Cyst Need to Be Removed?

Usually not.

Most Baker’s cysts are initially treated without surgery.

Management may include:

  • Observation when symptoms are mild

  • Activity modification

  • Treatment of knee arthritis or inflammation

  • Physiotherapy and strengthening

  • Medication when clinically appropriate

  • Aspiration in selected cases

  • Injection treatment in carefully selected patients

The underlying knee problem should be treated whenever possible.

Removing or draining fluid without addressing arthritis, meniscal pathology or inflammation may allow the cyst to return.

Surgical removal is rarely the first treatment.

It may be considered when a large or recurrent cyst causes persistent symptoms, compresses nearby structures or remains problematic despite appropriate treatment.

Can a Baker’s Cyst Burst?

A Baker’s cyst can occasionally leak or rupture.

This may cause:

  • Sudden calf pain

  • Calf swelling

  • Tightness

  • Redness or warmth

  • Fluid tracking down the leg

These symptoms can resemble a deep vein thrombosis.

It is not safe to assume that sudden calf swelling is caused by a ruptured cyst without medical assessment.

Knee Osteoarthritis

Knee osteoarthritis is a common underlying cause of posterior knee discomfort and Baker’s cyst formation.

Arthritis may lead to:

  • Excess joint fluid

  • Swelling

  • Pain while walking

  • Stiffness after sitting

  • Difficulty climbing stairs

  • Reduced knee movement

  • Grinding or creaking

  • Bow-leg or knock-knee deformity

  • Night or rest pain in more symptomatic disease

Pain may be felt mainly at the front, inner or outer side of the knee, but some patients experience pressure or tightness behind the joint.

Early and moderate arthritis can often be managed without surgery.

Advanced arthritis may require knee replacement when pain, stiffness, deformity and loss of function substantially affect quality of life despite appropriate non-surgical treatment.

Read Knee Arthritis Treatment in Mumbai by Dr. Mayur Rabhadiya.

Knee Effusion or Water in the Knee

Excess fluid inside the knee can increase pressure throughout the joint.

Some of this fluid may collect behind the knee and create:

  • Tightness

  • Fullness

  • Reduced bending

  • Pain while walking

  • Stiffness after rest

  • A Baker’s cyst

  • Swelling extending toward the calf

The cause of the effusion may include:

  • Knee arthritis

  • Meniscal injury

  • Ligament injury

  • Gout

  • Inflammatory arthritis

  • Infection

  • Trauma

  • Previous surgery

Read Knee Swelling and Water in the Knee.

A hot, red and rapidly swollen knee, particularly with fever or systemic illness, requires prompt medical assessment.

Meniscal Injury or Degeneration

The posterior portions of the medial and lateral menisci lie toward the back of the knee.

A meniscal injury may cause:

  • Pain along the inner or outer joint line

  • Pain extending toward the back of the knee

  • Swelling

  • Pain while twisting

  • Clicking

  • Catching

  • Difficulty squatting

  • Locking in selected cases

  • Reduced knee movement

A traumatic tear may follow a twisting injury.

Degenerative meniscal changes may develop gradually with age or arthritis.

Not every meniscal tear requires surgery.

Treatment depends on:

  • Whether the tear is traumatic or degenerative

  • Tear pattern and location

  • Presence of true mechanical locking

  • Arthritis severity

  • Patient age

  • Activity requirements

  • Response to rehabilitation

Patients with related symptoms can read:

Hamstring Tendon Irritation

The hamstring muscles cross behind the knee.

Their tendons may become painful because of:

  • Running

  • Sprinting

  • Sudden acceleration

  • Repetitive exercise

  • Muscle weakness

  • Reduced flexibility

  • Previous hamstring injury

  • Training-load errors

  • Inadequate recovery

Symptoms may include:

  • Pain toward the inner or outer back of the knee

  • Tenderness over a tendon

  • Pain while bending the knee against resistance

  • Pain after running

  • Tightness during stretching

  • Discomfort during acceleration

Treatment commonly involves progressive strengthening and correction of contributing training factors rather than prolonged complete rest.

Gastrocnemius or Calf Muscle Injury

The gastrocnemius muscle begins above the knee and extends into the calf.

A muscle strain may occur during:

  • Running

  • Jumping

  • Sudden acceleration

  • Tennis or racquet sports

  • Pushing off forcefully

  • A sudden change of direction

Symptoms may include:

  • Sudden pain behind the knee or upper calf

  • Tenderness

  • Difficulty walking

  • Pain while pushing off

  • Bruising

  • Swelling

  • Pain while stretching the calf

A muscle injury should be distinguished from a blood clot, particularly when swelling is substantial or there was no clear injury.

Popliteus Muscle or Tendon Irritation

The popliteus is a small structure at the back of the knee that contributes to rotational control.

It may become painful following:

  • Downhill running

  • Twisting

  • Sudden deceleration

  • Repetitive training

  • Sports requiring rotation

  • Posterolateral knee injury

Symptoms may include:

  • Pain behind and toward the outer side of the knee

  • Pain while rotating

  • Pain during downhill walking or running

  • Tenderness behind the joint

  • Pain while initiating knee bending

Popliteus-related pain may resemble meniscal, ligament or calf-related symptoms.

Ligament Injury

The ACL and PCL lie inside the knee, while collateral and posterolateral structures contribute to stability around the joint.

Ligament injury may cause:

  • Pain after trauma

  • Rapid swelling

  • Instability

  • Difficulty bearing weight

  • A popping sensation

  • Knee giving way

  • Reduced confidence during sports

A PCL injury may follow a direct impact to the front of a bent knee, such as a dashboard injury or sports collision.

Patients experiencing repeated instability can read Why the Knee Gives Way.

Inflammatory Arthritis

Rheumatoid arthritis and other inflammatory joint conditions may cause:

  • Joint swelling

  • Warmth

  • Posterior fullness

  • Prolonged morning stiffness

  • Pain in multiple joints

  • Fatigue

  • Recurrent inflammatory episodes

Persistent swelling involving several joints may require blood tests and specialist medical evaluation.

Gout or Crystal Arthritis

Gout may cause sudden:

  • Severe knee pain

  • Swelling

  • Redness

  • Warmth

  • Marked stiffness

  • Difficulty bearing weight

A hot and swollen knee should not be self-diagnosed because infection may appear similar.

Pain Referred From the Hip or Spine

Pain behind the knee may occasionally originate from the hip, lower back or nerves.

Possible clues include:

  • Lower-back pain

  • Buttock pain

  • Hip or groin pain

  • Numbness or tingling

  • Pain travelling down the leg

  • Weakness

  • Symptoms not reproduced by knee examination

Patients requiring a broader musculoskeletal assessment can visit Dr. Mayur Rabhadiya, Orthopedic Doctor in Mumbai.

Could Pain Behind the Knee Be a Blood Clot?

Yes, although many cases of posterior knee pain are musculoskeletal.

A deep vein thrombosis is a blood clot within a deep vein, usually in the leg.

Possible symptoms include:

  • Pain in one calf or thigh

  • One-sided leg swelling

  • Warmth

  • Skin colour change

  • Prominent or swollen veins

  • Throbbing discomfort

Risk may be higher following:

  • Recent surgery

  • Hospital admission

  • Prolonged immobility

  • A long journey

  • Previous DVT

  • Cancer

  • Pregnancy or recent childbirth

  • Certain hormone treatments

  • A known clotting disorder

Symptoms alone cannot reliably distinguish a DVT from a muscle injury or ruptured Baker’s cyst.

Urgent medical assessment and vascular ultrasound may be required when a blood clot is suspected.

Pain or leg swelling accompanied by breathlessness or chest pain requires emergency medical attention.

Pain Behind the Knee During Specific Activities

Read Knee Pain While Getting Up From a Chair.

Pain Behind the Knee When Bending

Pain during knee bending may be associated with:

  • Baker’s cyst

  • Joint effusion

  • Meniscal injury

  • Hamstring tendon irritation

  • Knee arthritis

  • Calf or soft-tissue tightness

A large cyst or significant joint swelling may mechanically restrict bending.

Pain Behind the Knee When Straightening

Possible causes include:

  • Baker’s cyst

  • Joint swelling

  • Hamstring tightness

  • Posterior capsule irritation

  • Meniscal pathology

  • Knee arthritis

  • Muscle or tendon injury

Read Knee Locking and Catching.

Pain Behind the Knee While Squatting

Deep knee bending may aggravate:

  • Meniscal pathology

  • Baker’s cyst

  • Knee arthritis

  • Joint swelling

  • Hamstring or calf structures

Pain during squatting does not automatically mean that a meniscal tear requires surgery.

Pain Behind the Knee After Running

Running-related posterior knee pain may result from:

  • Hamstring tendon overload

  • Gastrocnemius strain

  • Popliteus irritation

  • Meniscal pathology

  • Baker’s cyst

  • Sudden increase in running distance

  • Hill or downhill training

  • Inadequate recovery

Read Knee Pain After Running or Exercise.

Pain Behind the Knee With a Lump

A lump behind the knee may be caused by a Baker’s cyst, but not every lump should be assumed to be a cyst.

Clinical assessment may consider:

  • Whether it is soft or firm

  • Whether it changes with knee position

  • Whether it is painful

  • Whether it is growing

  • Whether calf swelling is present

  • Whether there are neurological or vascular symptoms

Ultrasound may help determine whether the lump is fluid-filled or solid.

An enlarging, unexplained or persistent mass requires medical assessment.

Pain Behind the Knee With Swelling

Swelling may be associated with:

  • Baker’s cyst

  • Knee arthritis

  • Meniscal injury

  • Ligament injury

  • Gout

  • Inflammatory arthritis

  • Infection

  • Muscle injury

  • DVT or another vascular condition

Read Knee Swelling and Water in the Knee.

A hot, red and rapidly swollen knee requires prompt medical evaluation.

One-sided calf swelling requires assessment for vascular causes.

Pain Behind the Knee With Clicking

Clicking may occur with:

  • Meniscal pathology

  • Knee arthritis

  • Tendon movement

  • Joint swelling

  • Previous surgery

Painless clicking is not always clinically significant.

Clicking associated with pain, swelling, locking or instability should be assessed.

Read Clicking Sound in the Knee.

Pain Behind the Knee With Locking

Locking or catching may occur with:

  • Meniscal injury

  • Loose cartilage or bone fragment

  • Arthritis

  • Joint swelling

  • Pain-related muscle guarding

True mechanical locking means that the knee becomes physically blocked and cannot straighten normally.

Read Knee Locking and Catching.

Pain Behind the Knee With Giving Way

Instability may be related to:

  • Ligament injury

  • Meniscal pathology

  • Muscle weakness

  • Pain-related inhibition

  • Advanced arthritis

  • Patellar instability

Repeated giving way increases the risk of falling and requires evaluation.

Read Why the Knee Gives Way.

Pain Behind the Knee at Night

Night pain may occur with:

  • Symptomatic knee arthritis

  • Baker’s cyst

  • Joint inflammation

  • Swelling

  • Hamstring or calf irritation

  • Sleeping position

  • Pain referred from the spine

Persistent night pain, rest pain or rapidly worsening symptoms should be evaluated.

Read Why Knee Pain Is Worse at Night.

Pain Behind the Knee Without an Injury

Posterior knee pain may develop without a clear fall or twisting event.

Possible causes include:

  • Baker’s cyst

  • Knee osteoarthritis

  • Degenerative meniscal changes

  • Hamstring tendon overload

  • Repetitive walking or running

  • Inflammatory arthritis

  • Pain referred from the spine

  • DVT or another medical condition

Sudden pain and calf swelling without injury should not be assumed to be a muscle strain.

Read Knee Pain Without an Injury.

Pain Behind the Knee in Older Adults

Common causes in older adults include:

  • Knee osteoarthritis

  • Baker’s cyst

  • Degenerative meniscal changes

  • Joint swelling

  • Muscle weakness

  • Hamstring or calf-related pain

  • Previous knee surgery

Evaluation should also consider medical and vascular causes, particularly when there is one-sided calf swelling or recent immobility.

Read Knee Pain in Older Adults.

Pain Behind the Knee After Knee Replacement

Some posterior discomfort may occur temporarily during recovery because of:

  • Swelling

  • Reduced knee movement

  • Muscle tightness

  • Rehabilitation

  • Altered walking mechanics

Persistent, increasing or newly developed pain requires evaluation.

Possible causes after knee replacement include:

  • Infection

  • Implant loosening

  • Instability

  • Stiffness

  • Soft-tissue irritation

  • Baker’s cyst

  • Implant positioning or alignment problems

  • Pain referred from the hip or spine

  • DVT, particularly during the post-operative period

Warning signs include:

  • Increasing redness

  • Wound discharge

  • Fever

  • Rapidly worsening swelling

  • Calf pain or swelling

  • Breathlessness

  • Chest pain

  • Inability to bear weight

Patients with persistent implant-related symptoms can read Revision Knee Replacement Surgery in Mumbai.

How Pain Behind the Knee Is Evaluated

Clinical History

Dr. Mayur Rabhadiya may assess:

  • Exact location of pain

  • Whether symptoms began suddenly or gradually

  • Presence of a lump

  • Knee or calf swelling

  • Recent injury

  • Walking limitation

  • Pain during bending or straightening

  • Clicking, locking or giving way

  • Night pain

  • Running or exercise history

  • Previous knee surgery

  • Recent hospital admission

  • Recent prolonged travel

  • Medical conditions

  • Blood-clot risk factors

  • Current medication

Physical Examination

The examination may include:

  • Knee swelling and warmth

  • Palpation behind the knee

  • Knee range of movement

  • Joint-line tenderness

  • Meniscal tests

  • Ligament stability

  • Hamstring and calf assessment

  • Muscle strength

  • Walking pattern

  • Calf circumference and tenderness when appropriate

  • Neurological examination

  • Circulation assessment

  • Hip and spine examination when relevant

X-Rays

X-rays may be useful when there is concern about:

  • Knee osteoarthritis

  • Fracture

  • Joint-space loss

  • Deformity

  • Bone injury

  • Implant-related problems

A Baker’s cyst itself is not generally seen clearly on a routine X-ray, but the X-ray may identify an underlying arthritic condition.

Ultrasound

Ultrasound may help:

  • Identify a Baker’s cyst

  • Determine whether a lump is fluid-filled

  • Assess certain tendons and soft tissues

  • Guide aspiration in selected cases

  • Evaluate the veins when DVT is suspected

A routine musculoskeletal ultrasound and a vascular Doppler examination answer different clinical questions.

MRI

MRI may be considered when there is concern about:

  • Meniscal injury

  • Ligament injury

  • Cartilage damage

  • A large or unusual cyst

  • Persistent unexplained pain

  • Mechanical locking

  • A condition not adequately explained by examination and X-rays

MRI is not required for every patient with posterior knee pain.

Blood Tests or Joint Fluid Analysis

These may be considered when symptoms suggest:

  • Infection

  • Gout

  • Inflammatory arthritis

  • Another systemic condition

Testing should be directed by the clinical findings.

Treatment for Pain Behind the Knee

Treatment depends on the diagnosis.

Activity Modification

Temporary changes may include:

  • Reducing long walks

  • Limiting repeated stairs

  • Avoiding deep squatting

  • Reducing running distance

  • Avoiding downhill training temporarily

  • Reducing activities that increase swelling

  • Taking suitable movement breaks

Activity modification should support recovery rather than create permanent inactivity.

Therapeutic Exercise and Physiotherapy

A rehabilitation programme may include:

  • Quadriceps strengthening

  • Hip and gluteal strengthening

  • Hamstring strengthening

  • Calf strengthening

  • Knee range-of-motion exercises

  • Balance training

  • Walking retraining

  • Gradual return to running

  • Condition-specific loading

The programme should match the diagnosis.

A Baker’s cyst caused by arthritis requires a different strategy from a calf strain, meniscal injury or ligament problem.

Treatment of a Baker’s Cyst

Management may include:

  • Observation

  • Treatment of underlying arthritis

  • Reduction of aggravating activity

  • Physiotherapy

  • Medication when appropriate

  • Aspiration in selected cases

  • Injection treatment in selected patients

Repeatedly aspirating the cyst without controlling the knee condition may result in recurrence.

Surgery is rarely required solely to remove a Baker’s cyst.

Treatment of Meniscal Symptoms

Non-surgical treatment may include:

  • Activity modification

  • Reduction of twisting activity

  • Physiotherapy

  • Strengthening

  • Swelling management

  • Gradual return to activity

  • Medication when clinically suitable

Surgery may be considered when there is:

  • Persistent true mechanical locking

  • An appropriate repairable traumatic tear

  • Ongoing symptoms despite suitable rehabilitation

  • A structural problem that matches the symptoms

Degenerative meniscal changes associated with knee arthritis do not automatically require arthroscopy.

Treatment of Hamstring or Calf-Related Pain

Treatment may include:

  • Temporary reduction of aggravating activity

  • Progressive muscle loading

  • Strengthening

  • Gradual return to running

  • Correction of training errors

  • Recovery planning

  • Movement assessment

Forceful stretching immediately after an acute muscle injury may aggravate symptoms.

Heat or Ice

Ice may help after:

  • A recent injury

  • Activity-related pain

  • Swelling

  • An acute flare

Heat may help stiffness when there is no acute swelling or suspected vascular problem.

Protect the skin and avoid prolonged direct application.

Medication

Medication may be used selectively for symptom relief and to support rehabilitation.

Selection should consider:

  • Age

  • Kidney function

  • Gastrointestinal risk

  • Cardiovascular history

  • Liver function

  • Blood-thinning medication

  • Other medicines

  • Existing medical conditions

Repeated self-medication without diagnosis may delay appropriate treatment.

Can a Baker’s Cyst Be Drained?

Yes, aspiration may be considered in selected patients.

However, patients should understand that:

  • The fluid may return

  • The underlying joint condition may continue producing fluid

  • Aspiration is not necessary for every cyst

  • Infection and vascular conditions should be considered where relevant

  • Ultrasound guidance may be used

  • Rehabilitation and treatment of arthritis may still be required

Aspiration should be performed using appropriate sterile technique after clinical assessment.

Can GFC Therapy Help Pain Behind the Knee?

GFC therapy may be considered when posterior knee discomfort or a Baker’s cyst is associated with suitable stages of knee osteoarthritis.

GFC therapy does not directly treat every lump or every cause of posterior pain.

It is not the primary treatment for:

  • Suspected DVT

  • A ruptured muscle or tendon

  • An acute ligament injury

  • A locked knee

  • A major traumatic meniscal tear

  • Infection

  • Gout flare

  • An unexplained mass

  • Advanced arthritis requiring replacement

Dr. Mayur Rabhadiya provides GFC Therapy for Knee Arthritis in appropriately selected patients.

Patients should understand:

  • The condition being treated

  • Stage of arthritis

  • Expected degree of relief

  • Likely duration of benefit

  • Limitations

  • Need for rehabilitation

  • Whether surgery may still be required

Patients comparing injection options can read GFC vs PRP and Other Knee Injections.

Does Pain Behind the Knee Require Surgery?

Most cases do not require immediate surgery.

Surgery may be considered when posterior pain is caused by:

  • A repairable traumatic meniscal tear

  • Persistent true mechanical locking

  • Significant ligament instability

  • A fracture

  • A major tendon injury

  • An unusually large symptomatic cyst compressing nearby structures

  • Advanced knee arthritis

  • A failed knee implant

  • Another clearly identified structural problem

Treatment should be directed at the underlying diagnosis rather than pain location alone.

Does a Baker’s Cyst Mean I Need Knee Replacement?

No.

A Baker’s cyst can occur with mild, moderate or advanced knee disease.

Knee replacement may be considered when advanced arthritis causes:

  • Severe persistent pain

  • Substantially reduced walking distance

  • Major difficulty with stairs

  • Severe stiffness

  • Progressive deformity

  • Night or rest pain

  • Loss of independence

  • Failure of appropriate non-surgical treatment

  • Substantial reduction in quality of life

The presence of a cyst alone is not an indication for replacement.

Patients uncertain about surgery can read:

Frequently Asked Questions About Pain Behind the Knee

What causes pain behind the knee?

Common causes include a Baker’s cyst, knee arthritis, joint swelling, meniscal problems, hamstring or calf injuries and ligament conditions.

What is a Baker’s cyst?

A Baker’s cyst is a fluid-filled swelling behind the knee that commonly develops because an underlying knee condition produces excess joint fluid.

Is a Baker’s cyst dangerous?

Most Baker’s cysts are not dangerous. However, sudden calf pain and swelling may resemble a blood clot and requires medical assessment.

Does a Baker’s cyst need to be removed?

Usually not. Most are initially managed by treating the underlying knee problem, modifying activity and using non-surgical care.

Can a Baker’s cyst return after drainage?

Yes. Fluid may return when the underlying knee condition continues producing excess joint fluid.

Can knee arthritis cause pain behind the knee?

Yes. Arthritis may cause joint effusion, stiffness and Baker’s cyst formation, producing pressure or pain behind the joint.

Can a meniscus tear cause posterior knee pain?

Yes. Tears involving the back portion of a meniscus may cause posterior or joint-line pain, swelling, clicking, catching or locking.

Why does the back of my knee hurt when I bend it?

Possible causes include a Baker’s cyst, joint swelling, meniscal pathology, arthritis or hamstring and calf structures.

Why does the back of my knee hurt when I straighten it?

A Baker’s cyst, posterior swelling, hamstring tightness, arthritis or a meniscal problem may cause pain during extension.

Can running cause pain behind the knee?

Yes. Hamstring, calf and popliteus overload, training errors, meniscal pathology or joint swelling may cause running-related posterior pain.

How can I tell a Baker’s cyst from a blood clot?

Symptoms can overlap. Sudden one-sided calf pain, swelling, warmth or skin-colour change requires medical assessment and may need a vascular ultrasound.

Can physiotherapy help pain behind the knee?

Yes, when the pain is related to arthritis, muscle weakness, tendon overload, injury recovery or reduced movement. The programme should match the diagnosis.

Can GFC therapy treat a Baker’s cyst?

GFC may be considered when symptoms are driven by suitable stages of knee arthritis. It does not directly treat every cyst or cause of posterior pain.

Does pain behind the knee mean I need surgery?

No. Most causes are initially treated non-surgically. Surgery is reserved for selected structural injuries, advanced arthritis or persistent complications.

When should posterior knee pain be investigated?

Evaluation is advisable when pain persists, a lump is present, swelling repeatedly returns, movement is restricted or symptoms follow an injury.

Which doctor should I consult for pain behind the knee in Mumbai?

An orthopedic surgeon experienced in knee arthritis, Baker’s cysts, meniscal injuries and both non-surgical and surgical knee care can identify the cause and recommend an individualised plan.
