Who Needs a Hip Replacement?

Common causes and conditions that lead to surgery

+

A hip replacement is usually considered only when the hip joint is severely damaged and conservative treatments no longer give adequate relief. In this surgery, the worn or damaged joint surfaces are replaced with an artificial implant to relieve pain and restore movement. The most common reasons people need a hip replacement include:

  • Severe osteoarthritis of the hip — cartilage wear leading to bone-on-bone friction, pain, and stiffness
  • Avascular necrosis (AVN) — loss of blood supply to the head of the femur, causing the bone to weaken and collapse
  • Hip fracture — especially neck-of-femur fractures in older adults, often after a fall
  • Rheumatoid arthritis of the hip — inflammatory joint destruction from an autoimmune disease
  • Other causes — hip dysplasia, old untreated injuries, or a previous hip surgery that has failed over time
🩺

Symptoms

What patients typically notice

+
  • Persistent pain in the groin, sometimes radiating to the thigh or knee
  • A noticeable limp when walking
  • Stiffness that makes it hard to move the hip fully — bending, rotating, or spreading the legs
  • Pain that disturbs sleep, especially when lying on the affected side
  • Difficulty climbing stairs, getting in or out of a car, or rising from a low chair
  • Trouble putting on shoes and socks, or other everyday tasks that need hip bending
  • Reduced walking distance over time and growing reliance on a stick or walker

⚠️ Seek urgent medical attention if hip pain follows a fall and you cannot bear weight on the leg, if the leg appears shortened or turned outward, or if hip pain is accompanied by fever, redness, or warmth around the joint — these can indicate a fracture or joint infection needing immediate evaluation.

Diagnosis

How the condition is confirmed

+

Clinical Examination

  • Assessment of hip range of motion, strength, and the specific movements that trigger pain
  • Gait assessment — observing how the patient walks, looking for a limp or compensatory patterns
  • Checking for leg length difference and muscle wasting around the hip

Imaging & Tests

  • X-ray of the pelvis and hip — the primary tool to confirm joint space narrowing, bone spurs, or fracture
  • MRI — used when avascular necrosis (AVN) is suspected, especially in early stages, or when X-rays are inconclusive
  • Blood tests — when infection or inflammatory arthritis (such as rheumatoid arthritis) is suspected

Treatment Options

From conservative care to total hip replacement

+

Conservative Care (First-Line)

  • Weight management to reduce the load carried by the hip joint
  • Physiotherapy to strengthen the muscles around the hip and core, and preserve range of motion
  • Walking aids such as a stick or walker to reduce pain and improve stability
  • Pain management with appropriate medications, used judiciously and under medical guidance
  • Activity modification — avoiding movements that aggravate pain and using assistive devices for daily tasks

Surgical Options: Total Hip Replacement

  • Total hip replacement (THR) — the worn ball-and-socket joint is replaced with an artificial implant; recommended when pain and disability significantly affect quality of life despite conservative treatment
  • Minimally invasive techniques — smaller incisions and muscle-sparing approaches that can reduce tissue trauma and support faster early recovery in suitable patients
  • Robotic-assisted hip replacement — uses detailed pre-operative planning and intra-operative guidance to help achieve precise implant positioning
  • Hemiarthroplasty — replacing only the femoral head, sometimes used in certain fracture cases in older patients

What to Expect: Recovery Timeline

  • Day 1: most patients stand and begin walking with support (walker or crutches) within a day of surgery
  • Weeks 1-6: walking distance gradually increases, and most people resume most daily activities by 4 to 6 weeks
  • Around 3 months: full recovery, with most patients able to return to their normal activities and routines

💡 Most well-functioning hip replacements last 15 to 20 years or longer. The decision to go ahead with surgery should be based on how much your symptoms are limiting your daily life — not on age or X-ray findings alone.

Exercises

Pre-hab before surgery, strengthening after

+

Exercise plays an important role both before and after hip replacement. "Pre-hab" — strengthening the muscles around the hip before surgery — can make recovery smoother, while structured post-operative exercises help restore strength, movement, and confidence in walking. Your surgeon and physiotherapist will guide a program tailored to your surgical approach and recovery stage.

Dr. Sumit's Advice

A clinical perspective on timing your surgery

+

"I tell my patients the same thing every time: hip replacement is not a decision to rush into, but it's also not one to delay indefinitely once your quality of life has been badly affected. I look closely at how much the pain is limiting your walking, sleep, and independence — not just at an X-ray. For some patients, conservative care genuinely works well for years. For others, waiting too long only means more muscle weakness and a harder recovery. My aim is always to time the surgery right for you as an individual, using an approach — whether minimally invasive or robotic-assisted — suited to your anatomy and needs."
