Partial Knee Replacement Surgeon in Ahmedabad, Gujarat

What is partial knee replacement?

Partial knee replacement, also called unicompartmental knee replacement, resurfaces only the single worn compartment of the knee rather than the whole joint. The healthy cartilage, bone and ligaments in the other compartments are left completely undisturbed, including the ACL, which a total replacement often removes. Because so much of your own knee is preserved, the joint continues to move and feel closer to a natural knee, and if the arthritis ever spreads years later, a partial tear can usually be converted to a total replacement.

Who is a candidate for partial knee replacement?

Partial knee replacement suits patients whose arthritis or damage is confined to one compartment of the knee, with the ACL and other ligaments intact. It is best for early or localised osteoarthritis rather than widespread joint deterioration, in patients who want to preserve as much of their natural knee structure as possible. The final decision is made on standing X-rays and examination, which confirm that the other compartments and the ligaments are healthy.

The CROWN technique

Dr. Hiren Patel performs partial knee replacement using his own CROWN approach - Conserve, Restore, Only the affected part resurfaced, Without extended pain or physiotherapy, Natural feel. By targeting only the damaged part of the knee and leaving healthy bone, cartilage and ligaments in place, the technique aims for a smaller, gentler operation and a joint that behaves more like your own than a total replacement typically can.

Partial vs total knee replacement

The two operations treat very different knees. A partial replacement is the more conservative option when only one compartment is worn; a total replacement is the right choice once arthritis is widespread.

For widespread arthritis, see total knee replacement; for the full picture, read the knee replacement overview.

How partial knee replacement is performed

Through a smaller incision than a total replacement, only the worn compartment is exposed. The damaged cartilage and a thin layer of bone are removed, and a metal-and-plastic implant is fitted to resurface just that part of the joint. Because the healthy compartments, the kneecap mechanism and the ligaments are not disturbed, there is less soft-tissue trauma - which is a large part of why the early recovery is quicker and the knee feels more natural afterwards.

The TRINOVA Approach in Partial Knee Replacement

Alongside the CROWN technique, Dr. Hiren Patel applies three additional elements - together known as TRINOVA - to make partial knee replacement even more precise and gentle on the surrounding muscle and tissue.

Robotic assistance (ROSA)

ROSA measures the knee live during surgery, so implant size, position and limb alignment follow the surgical plan rather than the feel of the moment. In a partial replacement, this precision matters even more, since only the damaged compartment is being resurfaced and the healthy compartments must be protected from any misalignment.

Subvastus approach

The knee is opened underneath the vastus medialis instead of cutting through the quadriceps tendon, so the muscle that straightens your leg is left intact. Combined with the already-smaller CROWN incision, this further reduces muscle trauma, supporting a quicker return of natural knee movement.

Tourniquet-less surgery

The operation is done without a thigh tourniquet, so blood supply to the leg muscles is never cut off during surgery. This helps limit post-operative swelling and stiffness, which fits well with the faster, near-normal recovery that partial knee replacement patients typically expect.

Recovery after partial knee replacement

Hospital stay is typically two to three days, and walking with support is usually possible within a few days of surgery. Around 95% of patients recover within about two weeks, with a return to light activities by four to six weeks. The smaller incision and preserved ligaments mean less pain and a shorter physiotherapy course than a total replacement, though a steady home exercise routine still matters for the best result.

Partial knee replacement cost in Ahmedabad

Partial knee replacement in Ahmedabad typically ranges from Rs 1.5 lakh to Rs 3.5 lakh, depending on surgical method, implant type and hospital room category, often less than a total replacement because the operation is smaller.
