Pain After Hip Replacement
Pain after hip replacement should be interpreted by when it began, where it is felt, what provokes it, whether function is improving or declining, and whether warning signs are present. Incisional and muscular soreness that gradually improves is expected early. New, worsening or recurrent pain after a previously good recovery requires diagnosis rather than repeated pain medicine, injections or revision surgery without a defined cause.

Quick Answer
Early pain should show an overall improving trend, even when individual days vary.
Worsening pain, wound drainage, inability to bear weight, sudden deformity, marked calf swelling, chest pain or breathlessness needs urgent assessment.
Persistent pain may arise from infection, loosening, fracture, instability, iliopsoas irritation, abductor or trochanteric problems, the spine, nerves or another medical condition.
A normal X-ray does not exclude infection, tendon problems, subtle instability or referred pain.
Infection should be considered before steroid injection or revision surgery.
Expected Early Pain Versus a Concerning Pattern
Expected early discomfort commonly comes from the incision, muscles, swelling and altered walking. It may increase after exercise or a longer walk and settle with rest, ice and the prescribed plan. The important feature is the overall direction: sleep, transfers, walking and medicine use should gradually improve.
Concern rises when pain steadily escalates, returns after a stable or improving period, changes suddenly after a fall, appears with wound drainage or systemic illness, or causes a new loss of weight bearing or function. A fixed number of days or weeks cannot determine whether pain is normal without considering the trend and associated findings.
Classify Pain by Timing
Days to weeks
Important causes include wound problems, infection, haematoma, blood clot, dislocation, fracture, medication-related problems and excessive or poorly progressed activity. Persistent drainage or increasing rest pain should not be dismissed because fever may be absent in joint-replacement infection.
Months after surgery
Weakness, gait disturbance, iliopsoas or abductor problems, trochanteric pain, leg-length perception, instability, infection and referred spinal pain may become clearer. Pain that never improved requires a different analysis from pain that improved and then returned.
Years after surgery
New pain after a long stable period raises concern for infection, wear, osteolysis, loosening, fracture, instability, tendon failure or pain arising from the spine, knee or another condition. NICE recommends orthopaedic referral for new or worsening pain, limp or loss of function related to a joint replacement.
What the Pain Location May Suggest
Groin or front-of-hip pain
Possible causes include acetabular loosening, infection, iliopsoas tendinopathy or impingement, occult fracture, instability, hernia or referred pain. Iliopsoas-related pain is often provoked by active hip flexion, climbing stairs, rising from a chair or lifting the leg into a car.
Lateral, thigh or buttock pain
Lateral pain may involve the abductor tendons, trochanteric tissues, weakness or altered gait. Thigh pain may relate to stem load transfer, fracture, loosening, infection or muscle recovery. Buttock or radiating leg pain may arise from lumbar stenosis, nerve-root compression or sacroiliac disease despite stable hip components.
Serious Causes to Exclude
Periprosthetic joint infection
Infection can present early or years later. Symptoms may include persistent or increasing pain, stiffness, swelling, redness or wound drainage. Fever may be absent. Assessment may include inflammatory blood tests and joint aspiration. In a stable patient, antibiotics should not be started casually before appropriate cultures because they can reduce diagnostic yield.

Dislocation, fracture and blood clot
A complete dislocation usually causes sudden severe pain, deformity and inability to stand. A periprosthetic fracture can follow a fall or minor trauma in fragile bone. Calf pain with marked one-sided swelling can indicate deep-vein thrombosis; sudden breathlessness or chest pain can indicate pulmonary embolism.

Loosening, wear and osteolysis
Loosening may produce start-up pain, progressive limp, reduced walking or new pain after a previously stable period. Wear debris can cause bone loss around components. Serial X-rays are often more informative than one isolated image.

Important Soft-Tissue Causes
Iliopsoas tendinopathy or impingement
Iliopsoas irritation is an important cause of persistent groin pain. Pain is often worse with active hip flexion, stairs, rising from sitting or getting into a car. Causes can include anterior cup prominence, a long screw, retained cement, altered offset or tendon irritation without a major component problem.
Assessment may use lateral radiographs, CT or ultrasound and a targeted diagnostic injection after infection has been considered. Treatment may include load modification and rehabilitation; refractory cases require a decision between tendon surgery and component revision based on the structural cause.
Abductor and trochanteric problems
Gluteus medius or minimus weakness or tendon damage may cause lateral pain, limp and difficulty standing on one leg. Trochanteric pain may cause tenderness and pain while lying on the operated side. Treatment should address gait, abductor strength and load progression.
Leg-Length Perception and Pain
A hip may feel longer or shorter because of pelvic tilt, muscle tightness, spinal alignment, contracture or previous deformity. Perceived and measured structural differences are not the same. The surgeon balances stability, offset and leg length rather than pursuing one measurement in isolation.

How the Painful Hip Replacement Is Investigated
Pain timing, location, rest or start-up pattern, falls, infections, wound changes and current function compared with the best postoperative function.
Operation note, implant details and comparison with previous radiographs.
Gait, limb length, wound, hip movement, resisted hip flexion, abductor strength and neurological and vascular examination.
Standard pelvis and hip radiographs, followed by targeted CT, ultrasound, nuclear imaging or metal-artifact-reduction MRI when a specific question remains.
Inflammatory blood tests and joint aspiration when infection is possible.
Selected image-guided local anaesthetic injection when a soft-tissue source is suspected after infection and mechanical failure have been considered.
Treatment Must Match the Diagnosis
Expected recovery pain: analgesia, ice, pacing and progressive rehabilitation.
Weakness or gait problems: targeted physiotherapy and walking-aid review.
Iliopsoas or trochanteric pain: load modification, targeted rehabilitation and selected image-guided treatment.
Spine or nerve pain: neurological and spinal evaluation with condition-specific care.
Infection: specialist surgical and microbiological planning.
Fracture, recurrent instability or confirmed loosening: fixation, component revision or another defined surgical treatment when indicated.
Revision surgery should address a demonstrated failure mechanism. Revision for unexplained pain without a clear diagnosis has a less predictable chance of relief. Read Hip Replacement Second Opinion in Mumbai.

Questions Patients Commonly Ask
How long is pain normal after hip replacement?
There is no single cutoff. Early pain should show an overall improving trend. Worsening pain, loss of function, drainage or systemic symptoms requires review regardless of the number of weeks.
Does a normal X-ray mean nothing is wrong?
No. X-rays are essential but may not show early infection, tendon disorders, subtle instability or referred pain. Further tests should answer a specific clinical question.
Can the spine cause pain after a successful hip replacement?
Yes. Lumbar nerve compression and other spinal conditions can cause buttock, thigh or leg pain while the implant remains stable.
Does persistent pain always require revision?
No. Treatment depends on the cause. Soft-tissue, spinal and rehabilitation problems may not require implant revision.
