Partial or Total Knee Replacement — The Decision That Determines Your Recovery

If you're suitable for a partial knee replacement, recovery is faster, the knee feels more natural, and bone is preserved for future revision. The catch: only the right candidates qualify.

Dr. Harjoban Singh — the only FIFA-approved orthopaedic surgeon in the Chandigarh Tricity — sees patients with this condition regularly. Most cases are treated without surgery first.

What Each Surgery Actually Replaces

The knee has three compartments: medial (inner), lateral (outer), and patellofemoral (kneecap).

Partial (unicompartmental) replacement resurfaces only the damaged compartment — usually the medial side. The other two compartments, the cruciate ligaments, and the meniscus on the other side are left intact.

Total knee replacement resurfaces all three compartments. The ACL is removed (always), the PCL may be retained or removed depending on the implant design, and the menisci are removed.

If only one compartment is worn, replacing the whole knee is over-treatment. If three compartments are worn, replacing only one is under-treatment that fails within 2–3 years.

Who Is Suitable for Partial Replacement

Roughly 15–25% of patients coming for knee replacement are genuinely suitable for partial (unicompartmental) replacement. The criteria:

  • Wear confined to one compartment — confirmed on standing X-ray and MRI.
  • Intact ACL (the partial implant relies on it for stability).
  • Functional range of motion — no significant flexion contracture (> 15°).
  • Stable knee — no significant varus/valgus deformity that doesn't correct passively.
  • BMI ideally under 35.
  • Inflammatory arthritis (rheumatoid) is a contraindication — total replacement is needed.

Honest reality:

Some surgeons do partial replacement on patients who shouldn't have it (because the recovery sells well). Others avoid partial replacement entirely (because it's a more demanding surgery). Dr. Harjoban Singh's approach: recommend partial when genuinely indicated, total when the joint truly needs it.

How Robo-Navigation Helps Both

Robotic / computer-navigated surgery improves implant alignment to within 1° of the planned position. For partial replacement, where 2° of malalignment can cause early failure, robotic precision is especially valuable.

At Gini, every joint replacement uses GiniVision™ AR navigation — not as a marketing line, but because the data on revision rates with navigated surgery is now clear: better alignment, fewer outliers, longer implant survival.

Can Partial Be Converted to Total Later?

Yes. One of the genuine advantages of partial replacement: if it wears out 12–15 years later, conversion to total knee replacement is possible and gives results similar to a primary total replacement — because bone has been preserved.

Compare with revision of a failed total: more complex, more bone loss, results never quite as good as the primary surgery. So when partial is genuinely indicated, it preserves your future options.

Frequently Asked Questions

Partial (unicompartmental) replacement resurfaces only one of the three knee compartments, preserving the cruciate ligaments and the unaffected meniscus. Total replacement resurfaces all three compartments and removes the ACL. Partial recovers faster and feels more natural but is only suitable when damage is localised.
Partial. Walking unaided in 2–3 weeks vs 4–6 weeks. Driving in 3–4 weeks vs 6 weeks. Return to office work in 3 weeks vs 6 weeks. Bone and ligament preservation is why.
Yes. If a partial replacement wears out after 12–15 years, it can be revised to a total knee replacement with results similar to a primary total replacement, because the bone stock has been preserved.
Suitability requires: damage in only one compartment (confirmed on X-ray and MRI), intact ACL, no significant flexion contracture, stable knee alignment, BMI ideally under 35, and no inflammatory arthritis. About 15–25% of knee replacement patients meet these criteria.
At Gini, partial knee replacement typically costs ₹2.5–3.5 lakhs (implant-dependent); total knee replacement ₹3–4.5 lakhs. CGHS rates apply for empanelled patients. Cashless under most insurance.
