There comes a point in the progression of joint disease — arthritis, avascular necrosis, post-traumatic deterioration — when the pain is no longer manageable with medication, the walking distance has shrunk to a few hundred metres, stairs have become a daily negotiation, and sleep is disrupted by aching joints. At this point, the question shifts from “how do I manage this?” to “which joint replacement is right for me, and who should do it?”
As Faridabad’s leading UK-trained orthopedic doctor in Faridabad and joint replacement subspecialist, Dr. Sunil Choudhary at the Bone & Joints Clinic has performed over 2,000 joint replacement surgeries across the knee, hip, and shoulder. This guide explains each replacement type, who qualifies, what modern surgical techniques offer, and the questions every patient should ask before consenting to surgery.
Joint arthroplasty — the medical term for joint replacement — replaces damaged joint surfaces with prosthetic components, recreating a smooth, pain-free articulating surface. Contrary to common belief, joint replacement does not replace the entire bone. It resurfaces the ends of bones where they meet at the joint, leaving the bone itself intact.
What joint replacement reliably achieves:
What joint replacement cannot guarantee:
The knee is the most commonly replaced joint — and the one where Faridabad patients most frequently present to Dr. Sunil Choudhary’s clinic.
All three compartments of the knee (medial, lateral, and patellofemoral) are replaced — the femoral condyles, tibial plateau, and patellar surface. A metal femoral component and polyethylene tibial insert recreate smooth articulation.
Who needs TKR:
Modern TKR at Dr. Sunil Choudhary’s clinic:
Expected longevity: 90% of modern TKR implants function well at 15 years; 80% at 20 years.

Only the diseased compartment — usually the medial — is replaced, preserving both cruciate ligaments and the healthy cartilage of the other compartments.
Why UKR when it’s appropriate:
When UKR is not appropriate:

When a previous knee replacement has failed — from loosening, infection, implant wear, instability, or periprosthetic fracture — revision surgery replaces the failed components. The most technically demanding procedure in knee arthroplasty.

The femoral head (ball) and acetabulum (socket) are both replaced — with a stem in the femoral canal, a metal or ceramic femoral head, and a cup fixed in the acetabulum.
Who needs THR:
Bearing surface options at Dr. Sunil Choudhary’s clinic:
Surgical approaches used:
Expected longevity: Modern THR provides 15–20+ functional years in the majority of patients.

Only the femoral head (ball) is replaced — the native acetabular socket is preserved. The primary indication is displaced femoral neck fractures in elderly patients, where the blood supply to the femoral head is disrupted and risk of avascular necrosis makes fracture fixation unsuitable.
For partial hip details: Partial Hip Replacement
For failed total hip replacements — component loosening, bearing surface wear, dislocation, infection, or periprosthetic fracture.

The humeral head and glenoid are both resurfaced. The primary indication is glenohumeral osteoarthritis with an intact or repairable rotator cuff.

The biomechanics are reversed — the ball is placed on the glenoid side, the socket on the humeral side. This allows the deltoid to power shoulder elevation independent of the rotator cuff.
Primary indications:
For reverse shoulder details: Reverse Shoulder Replacement
Shoulder Hemiarthroplasty
The humeral head alone is replaced — preserving the native glenoid. Used for selected proximal humeral fractures and early AVN.
For shoulder hemiarthroplasty: Shoulder Hemiarthroplasty
Conventional joint replacement uses mechanical cutting guides to position implant components. Robotic-assisted arthroplasty uses a pre-operative CT scan to create a 3D digital model of the patient’s joint, plans the implant position virtually, and then guides the surgeon’s instrument in real-time with sub-millimetre accuracy.
Clinical benefits documented in published literature:
At Dr. Sunil Choudhary’s Bone & Joints Clinic, robotic-assisted arthroplasty is available for appropriate knee and hip replacement candidates — making Faridabad patients eligible for the most advanced joint replacement precision available globally.

Joint replacement surgery — whether of the knee, hip, or shoulder — is one of the most transformative elective operations in medicine when the right procedure is performed on the right patient by the right surgeon. As Faridabad’s foremost orthopedic doctor in Faridabad for joint replacement, Dr. Sunil Choudhary provides the full spectrum — conventional and robotic, primary and revision — with 20+ years and 2,000+ surgeries of subspecialty experience.
