Unicompartmental knee arthroplasty for medial compartmental knee osteoarthritis in young and middle-aged patients: a short-term follow-up

doi:10.3969/j.issn.2095-4344.1079

Abstract

Abstract:

BACKGROUND: With the development of surgical instruments and techniques, the unicompartmental knee arthroplasty has been accepted. However, there is still a lack of report on unicompartmental knee arthroplasty for treating medial compartmental knee osteoarthritis in young patients in China.

OBJECTIVE: To evaluate the clinical curative effect of unicompartmental knee arthroplasty for medial compartmental knee osteoarthritis in young patients.

METHODS: Sixteen patients less than 55 years of age with medial compartmental knee osteoarthritis were treated by unicompartmental knee arthroplasty with Oxford III system from June 2013 to June 2017 at Third Department of Orthopedics,Gansu Provincial Hospital. Curative effects were evaluated by Visual Analogue Scale, Hospital for Special Surgery score, range of motion and angle of femorotibial angle and hip-knee-ankle angle before and after surgery.

RESULTS AND CONCLUSION: (1) Primary healing of incision was obtained in all patients, and no infection, fat embolism or fracture around the prosthesis occurred except one case of lower limb deep venous thrombosis. (2) All the patients were followed up for 6-36 months. (3) At the postoperative last follow-up, Visual Analogue Scale, Hospital for Special Surgery score, and range of motion of the knee joint were significantly improved compared with the baseline (P < 0.05). (4) The postoperative femorotibial angle and hip-knee-ankle angle were significantly improved compared with the baseline (P < 0.05). (5) These findings suggest that the unicompartmental knee arthroplasty for treating medial compartmental knee osteoarthritis in young patients has a good short-term effect. The moderate- and long-term efficacy needs long follow-up.
