Hip Replacement (partial/revision/total)

Hip replacement surgery is one of the most commonly performed and highly successful orthopaedic procedures offered at Moolchand Hospital, recognized as one of the best orthopaedic hospitals in Delhi and a leading destination for joint replacement surgery. The procedure involves removing damaged or worn components of the hip joint and replacing them with precisely fitted artificial implants made from high-quality metal, ceramic, or polyethylene materials that replicate the smooth, pain-free movement of a healthy hip joint.

The hip is a ball-and-socket joint — the rounded head (ball) of the femur (thigh bone) fits into the acetabulum (socket) of the pelvis. Conditions such as advanced osteoarthritis, rheumatoid arthritis, avascular necrosis (AVN), hip fractures, post-traumatic arthritis, and bone tumours can severely damage the articular cartilage and bone surfaces of the hip joint, causing debilitating pain, stiffness, and functional limitations that do not respond adequately to conservative treatment.

Partial Hip Replacement (Hemiarthroplasty) Partial hip replacement, or hemiarthroplasty, involves replacing only the femoral head (ball) component of the hip joint while leaving the natural acetabulum (socket) intact. It is most commonly performed for displaced femoral neck fractures in elderly patients — particularly following a fall — where preserving the acetabulum is appropriate as the socket cartilage remains healthy. The procedure is faster, involves less blood loss, and is associated with lower surgical risk compared to total hip replacement, making it well suited for frail elderly patients. Implant options include unipolar (fixed head) and bipolar (mobile head) hemiarthroplasty, with the bipolar design offering slightly better functional outcomes.

Total Hip Replacement (Total Hip Arthroplasty — THA) Total hip replacement is the gold standard surgical treatment for end-stage hip arthritis and is the most common type of hip replacement performed at Moolchand Hospital. The procedure involves replacing both the femoral head (ball) and the acetabulum (socket) with prosthetic components. The acetabular cup is implanted into the pelvis, a liner (polyethylene, ceramic, or metal) is placed inside the cup, and a femoral stem is inserted into the femoral canal topped with an artificial femoral head. Modern bearing combinations include ceramic-on-ceramic, ceramic-on-polyethylene, and metal-on-polyethylene, each with specific advantages in terms of wear resistance and longevity.

Minimally invasive total hip replacement techniques are available at Moolchand Hospital, using smaller incisions and muscle-sparing approaches (anterior approach or posterior approach with enhanced recovery protocols) that reduce blood loss, accelerate recovery, and minimize post-operative pain. Computer-assisted navigation and robotic-arm assisted surgery may be used in selected cases to enhance implant positioning accuracy and optimize surgical outcomes.

Revision Hip Replacement Revision hip replacement is a complex surgical procedure to replace a previously implanted hip prosthesis that has failed due to aseptic loosening (the most common cause), wear of bearing surfaces, periprosthetic joint infection (PJI), periprosthetic fracture, implant fracture, instability and recurrent dislocation, or adverse tissue reactions to metal-on-metal implants. Revision surgery is significantly more challenging than primary replacement due to bone loss, scarring from previous surgery, and the need to remove well-fixed implants.

Revision procedures may involve partial revision (replacing only one component — femoral stem or acetabular cup) or full revision (replacing all components simultaneously). Bone grafting — using autograft, allograft, or synthetic bone substitutes — is often required to restore bone stock lost due to osteolysis around the failed implant. Highly porous revision implants with ingrowth surfaces provide stable biological fixation in deficient bone.

At Moolchand Hospital in Lajpat Nagar Delhi, our dedicated joint replacement surgeons have extensive experience in both primary and complex revision hip replacement surgery, supported by advanced pre-operative planning with 3D CT templating, modern implant systems, cell-saver technology to minimize blood transfusion requirements, and a structured Enhanced Recovery After Surgery (ERAS) protocol to maximize patient safety and accelerate rehabilitation.

Our physiotherapy and rehabilitation team begins post-operative mobilization as early as the day of surgery in suitable patients — a key principle of modern joint replacement care that reduces complications, shortens hospital stay, and speeds return to independence. Moolchand Hospital is widely recognized as one of the best orthopaedic hospitals in Delhi for joint replacement, offering comprehensive care from pre-operative assessment through surgery, rehabilitation, and long-term follow-up.
