Why Inner-Side Gap Narrowing on Standing X-Ray Decides Partial vs Total Knee Surgery
Dr. Prince Uchadiya shows on a standing knee X-ray what doctors actually mean when they say ‘ghutne ka gap kam ho gaya hai’. When cartilage wear is isolated to the inner half of the knee while your outer compartment and ACL ligament are healthy, you do not always need a full Total Knee Replacement.
- Always get a Standing (weight-bearing) Both-Knees X-ray rather than a lying-down film
- Saves 70% of your natural knee bone and preserves both natural cruciate ligaments

Not every painful arthritic knee needs all three compartments replaced with a full artificial joint. In nearly 25% to 30% of middle-aged and active older patients we see in Indore, knee pain sits strictly on the inner side (medial compartment) while the outer cartilage, kneecap cartilage, and ACL ligament are still completely healthy. For these knees, Partial Knee Replacement (Unicompartmental or Oxford Microplasty Knee Resurfacing) replaces only the worn-out 30% of the joint and preserves 70% of your own natural bone and ligaments.

Partial Knee Replacement (UKR) vs Total Knee Replacement (TKR): Honest Clinical Comparison
Families often wonder whether saving part of the knee is genuinely better or if doing a full Robotic or Muscle-Sparing Total Knee Replacement is safer. The right answer depends entirely on which compartments of your knee are worn out:
| Clinical Factor | Partial (Unicompartmental) Knee Replacement | Muscle-Sparing / Robotic Total Knee Replacement |
|---|---|---|
| Natural Knee Saved | Around 70% natural bone and cartilage preserved (only 1 compartment resurfaced) | All 3 compartments resurfaced for widespread global arthritis |
| ACL & PCL Ligaments | Both natural ACL and PCL stay intact, giving natural joint proprioception | ACL is removed; implant geometry provides stability |
| Incision & Tissue Trauma | Mini 7 to 8 cm incision without cutting the quadriceps tendon; virtually zero transfusion need | Subvastus muscle-sparing standard approach |
| Hospital Stay & First Walk | 2 to 3 days stay; assisted walking within 6 to 12 hours on Day 1 | 3 to 4 days stay; assisted walking on Day 1 |
| Post-Op Knee Bending | Effortless deep bending; many patients describe it as a ‘forgotten knee’ | Reliable pain-free walking and stairs for severe Grade 4 knees |
| 2026 Private Package in Indore | ₹1,25,000 to ₹2,20,000 (Cashless Mediclaim accepted) | ₹1,65,000 to ₹4,20,000 (see Knee Replacement Cost Guide) |
4 Signs You May Be an Ideal Candidate for Partial Knee Replacement in Indore
- The One-Finger Pain Test: When Dr. Prince asks where your knee hurts while walking or climbing stairs, you point with one finger directly to the inner side of your knee rather than all over the joint.
- Healthy Outer Compartment & Intact ACL: Standing X-rays (and stress X-rays or MRI when required) confirm bone-on-bone rubbing only on the inner side while the outer cartilage space and Anterior Cruciate Ligament remain strong.
- Good Pre-Surgery Knee Bend: Your knee still bends past 95 to 100 degrees and has only a mild, correctable bow-leg alignment rather than a rigid fixed deformity.
- Non-Inflammatory Osteoarthritis: Wear-and-tear medial knee osteoarthritis responds wonderfully to UKR, whereas autoimmune conditions like rheumatoid arthritis affect the whole joint lining and are better served by Total Knee Replacement.

Frequently Asked Questions: Partial Knee Replacement in Indore
1. Can a Partial Knee Replacement be converted to a Total Knee Replacement 15 to 20 years later if needed?
Yes, and that is one of its biggest advantages for patients in their late 40s, 50s, and early 60s. Because UKR preserves your natural bone stock and ligaments, converting it decades later behaves much like a straightforward primary Total Knee Replacement rather than a complex revision surgery.
2. What if my inner knee pain is from a Meniscus Root Tear rather than bone-on-bone arthritis?
If your joint cartilage is still healthy and MRI shows a fresh Meniscus Root Tear, Dr. Prince prioritizes keyhole meniscus root repair (with alignment correction if needed) so you keep 100% of your natural knee without any artificial implant at all. Read more in our Orthopaedic Second Opinion Guide.
Nearly one in four patients told they need a total knee replacement actually have isolated anteromedial osteoarthritis with an intact ACL – making them ideal candidates to preserve 70 percent of their native knee bone and natural joint feel.
