Abstract/OtherAbstract:
PURPOSE: Patients presenting anterior cruciate ligament (ACL) deficiency and isolated osteoarthritis of the medial compartment are treated either with biplanar osteotomy or with total knee arthroplasty (TKA). However, these patients between the forties and fifties are often very active in daily life and feel limited due to their knee. In order to follow the idea of preserving as much as possible from the joint, the concept of unicondylar joint replacement in conjunction with ACL reconstruction has been followed. There seems to be a limited experience with this concept. The purpose of the follow-up study was to evaluate the midterm clinical and functional outcome. METHODS: Twenty-seven patients were followed up for 53 months. The mean age of the 11 men and 16 women was 44 years. All patients were treated by combined unicompartmental knee arthroplasty and anterior cruciate ligament reconstruction. RESULTS: The Knee Society Score improved significantly from 77.1 ± 11.6 points to 166.0 ± 12.1 points (P ≤ 0.01). No revision surgery was required and no radiolucent lines were observed on the radiographs at the time of follow-up. The anterior translation showed less than 5 mm in 24 patients and 5 mm in the remaining 3 patients. CONCLUSIONS: The midterm clinical data have shown that combined surgery of UKA and anterior cruciate ligament reconstruction has revealed promising results. The restored knee stability seems to prevent the failure of UKA. However, long-term follow-up studies are required in these patients who received partial joint replacement fairly early in their life. LEVEL OF EVIDENCE: IV.
