Treatment
Partial Knee Replacement
When arthritis is confined to one compartment of the knee, a partial (unicompartmental) replacement resurfaces only the worn area, preserving the ligaments and the healthy parts of your own joint. See also our dedicated Unicompartmental Knee Replacement (UKR) page.
Who is suitable?
Around one in four patients with knee arthritis has wear confined to a single compartment, most often the inner side, with intact ligaments and a good range of movement. Careful selection is the key to a successful partial knee replacement, and Paddy Subramanian will assess your x-rays, examination and goals before recommending one.
The advantages
A partial replacement is a smaller operation than a total knee replacement: less bone is removed, blood loss is lower, the hospital stay is shorter and recovery is faster. Because the cruciate ligaments are preserved, the knee generally feels more natural. Many patients forget it is there.
The trade-offs, honestly
Registry data shows a slightly higher revision rate for partial replacements over time, partly because arthritis can progress in the untreated compartments. If that happens, conversion to a total knee replacement is usually straightforward. These trade-offs are discussed openly so you can make an informed choice.

Dr Subramanian has been approachable, professional and allowed me to consider what is a major surgery with confidence. All my questions were answered and I felt involved in the decision making. I am now back on my feet with a neat scar. I would recommend him highly to anyone.
