A DIFFERENTIATED APPROACH TO PRIMARY KNEE ARTHROPLASTY IN GONARTHROSIS PATIENTS

Abstract

Gonarthrosis is one of the topical orthopedic problems. One out of three all orthopedic patients are affected by knee osteoarthritis. Multiple studies demonstrate that this condition occurs most frequently in working-age population. Having studied the results of surgical treatment in 324 gonarthrosis patients, we have elaborated a differentiated approach to knee arthroplasties. A unicondylar arthroplasty is expedient for young patients; if flexion contracture of a knee exceeds 15°, we recommend a PLC non-preserving prosthesis; if a lesion of a tibial process exceeds 10 mm, we used a prosthesis with a tibial extensor; for total instability of knee, we used hinge-type constrained modifications of prostheses.
