When the hip fails through arthritis, fracture, or degeneration — replacement restores function reliably and permanently.
Walking becomes measured — you count steps to the kitchen. Getting up from a chair requires planning. Sleeping on one side becomes impossible. Hip replacement removes that limitation, and it does it reliably. Over 95% of hip replacements are still functioning well at 15 years.
Osteoarthritis — the most common reason. Cartilage wears away over decades until it is gone. Bone rubs on bone. The pain becomes constant.
Avascular necrosis (AVN) — the blood supply to the femoral head is lost, causing the bone to collapse. Common in younger patients, sometimes linked to steroid use or alcohol. Replacement is often needed.
Hip fractures — operated as an emergency. A fractured hip that is not operated within 48 hours carries significantly higher mortality in elderly patients. We operate 24 hours, 7 days.
Rheumatoid arthritis — inflammatory joint disease that destroys cartilage faster than osteoarthritis. Often presents in both hips.
Failed previous hip surgery — loose implants, periprosthetic infection, or implant fracture requiring revision.
Total hip replacement (THR) replaces both the femoral head and the acetabular cup. Hemiarthroplasty replaces only the femoral head and is typically used for hip fractures in elderly patients where a faster procedure is preferred. For arthritis and AVN, total replacement gives better long-term results and is the standard recommendation.
Cemented implants are fixed with bone cement — reliable in older patients with softer bone. Uncemented implants have a porous surface that allows bone to grow into the implant over time — preferred in younger, more active patients with good bone quality. Dr. Malhotra selects the appropriate fixation based on your age, bone density, and activity level.
Day 1: Walking with a walker. Hip precautions explained and practised with physiotherapy.
3–5 days: Discharged home. Most patients manage stairs before discharge.
6 weeks: Walking without walker. Driving possible for most patients.
3 months: Return to most daily activities. Low-impact exercise (walking, swimming) encouraged.
6–12 months: Full strength restored. Most patients describe the new hip as feeling completely natural.
