English to Polish Medical Medical (general)

Chodzi o slowo "unicompartmental". Jest np. "total knee replacement" - calkowita wymiana stawu kolanowego i "total knee prosthesis" - calkowita endoproteza stawu kolanowego. Tutaj bedzie to cos w rodzaju "jednoczesciowej". Problem w tym, ze nie wiem, jak nazywa sie po polsku "compartment" w kolanie.
knee replacement = wymiana stawu kolanowego
knee prosthesis = endoproteza stawu kolanowego.

Kontekst jest b. ubogi - znalazlam cos na ten temat w Internecie:

"A partial knee replacement (usually called a unicompartmental replacement) is done if only part of the knee joint is damaged by arthritis. Think of the knee as having three compartments: an inside, outside, and a front compartment for the kneecap. Most frequently, it is the inside compartment that becomes arthritic. The decision to perform a partial replacement is made only if other compartments have healthy, normal cartilage at surgery."
