Partial Knee Replacement (Microplasty) in Ahmedabad
By Dr. Kalpesh C. Patel · Consultant Orthopaedic Surgeon

Understanding the procedure
What is partial knee replacement?
The knee has three compartments: the inner side, the outer side, and the joint behind the kneecap. Arthritis often starts in just one of them — most commonly the inner side.
In a partial (unicompartmental) knee replacement, only that worn compartment is resurfaced. The rest of the knee, including the cruciate ligaments, is left in place. Because less of the knee is replaced, it often feels more natural afterwards and recovery is usually quicker than after a total knee replacement.
Not every knee is suitable. The decision rests on examination, X-rays and sometimes an MRI scan.
Who may be suitable
- Arthritis confined to one compartment, usually the inner side
- Intact ligaments, including the ACL
- A knee that straightens fully or nearly fully
- Pain felt mainly on one side of the knee
Who may need a different operation
- Arthritis in more than one compartment
- A damaged or missing ACL
- Inflammatory arthritis, such as rheumatoid arthritis
- Marked fixed deformity or stiffness
Microplasty
The Microplasty technique
Microplasty is an instrument system for the Oxford partial knee replacement, designed to make implant sizing and positioning more accurate and consistent.
Smaller incision
Carried out through a shorter incision than a total knee replacement, without turning the kneecap aside.
Precise instruments
Microplasty guides help set the bone cuts and implant size so the new surface matches your knee.
Ligaments preserved
The cruciate ligaments are kept, which helps the knee move and feel more like your own.
Total vs partial knee replacement
| Total knee replacement | Partial knee replacement | |
|---|---|---|
| What is replaced | All the joint surfaces | One worn compartment |
| Cruciate ligaments | ACL removed; PCL kept or replaced, depending on the implant | Kept |
| Incision | Longer | Shorter |
| Recovery | Usually longer | Usually quicker |
| Suited to | Arthritis across the knee, deformity or ligament damage | Arthritis in one compartment with healthy ligaments |
| Later surgery | Revision if the implant wears or loosens | Can be converted to a total knee if arthritis spreads |
Knee procedures offered
Partial Knee Replacement
Microplasty technique for arthritis confined to one compartment.
Total Knee Replacement
Full resurfacing when arthritis affects the whole knee.
Robotic Knee Replacement
Planned on a 3D model of your own knee.
Revision Surgery
Including conversion of a partial knee to a total knee.
Before surgery
When surgery isn’t the answer yet
Surgery is considered when arthritis is severe and these measures no longer control pain or protect your mobility. If they still work for you, that is the recommendation you will hear.
Strengthening exercise and physiotherapy
Weight management and activity changes
Pain relief medicines, as prescribed
Injections, in selected cases
Risks and limitations
Risks, complications and limitations
Partial knee replacement carries the general risks of any joint replacement. Your individual risks are discussed with you before any decision is made.
Infection
Uncommon, but taken seriously before, during and after surgery.
Blood clots
Reduced with early walking and preventive measures after surgery.
Arthritis elsewhere in the knee
Arthritis can progress in the other compartments over the years and may need conversion to a total knee replacement.
Implant wear over time
Implants can wear or loosen after many years and may need revision.

Common questions
Questions patients ask
Still unsure? Bring your questions to the consultation — that is what it is for.
You may be if arthritis is confined to one part of the knee and your ligaments are healthy. Examination and X-rays decide this.
An instrument system for the Oxford partial knee replacement, designed to make implant sizing and positioning more accurate and consistent.
Usually, yes. Less of the knee is operated on, so most patients walk and return to daily activity sooner.
Usually a shorter stay than after a total knee replacement. Your expected stay is discussed before surgery.
Many last well over a decade. Results depend on careful patient selection, activity and weight.
Yes. If arthritis spreads to the rest of the knee, a partial knee can be converted to a total knee replacement.
