Postoperative clinical outcomes of unicompartmental knee arthroplasty in patients with isolated medial compartmental osteoarthritis following medial meniscus posterior root tear
Background
Cartilage degradation progresses rapidly following medial meniscus posterior root tear (MMPRT). Unicompartmental knee arthroplasty (UKA) has been performed for medial compartmental osteoarthritis following MMPRT. We evaluated the clinical and radiographic outcomes of UKA for medial compartmental osteoarthritis after an untreated MMPRT.
Methods
Twenty-one patients who underwent UKA for isolated medial compartment osteoarthritis following MMPRT were retrospectively investigated. Clinical outcomes were assessed using the Knee Injury and Osteoarthritis Outcome Score and knee range of motion. The posterior tibial slope and tibial component inclination were evaluated using plain radiographs.
Results
The mean follow-up periods were 25.5 ± 13.8 months. Clinical outcomes improved significantly postoperatively. The mean postoperative knee extension angle was −1.1° ± 2.1°, and the knee flexion angle was 134.3° ± 4.9°. The posterior tibial slope angle decreased from 9.0° ± 2.0° preoperatively to 5.4° ± 1.8° postoperatively, and postoperative tibial component inclination at the final follow-up was 2.9° ± 1.1° varus. No aseptic loosening or deep infections were observed.
Conclusion
UKA significantly improved clinical outcomes and could be a viable surgical option for treating isolated medial compartmental osteoarthritis accompanied by untreated MMPRT.
期刊介绍：
The Asia-Pacific Journal of Sports Medicine, Arthroscopy, Rehabilitation and Technology (AP-SMART) is the official peer-reviewed, open access journal of the Asia-Pacific Knee, Arthroscopy and Sports Medicine Society (APKASS) and the Japanese Orthopaedic Society of Knee, Arthroscopy and Sports Medicine (JOSKAS). It is published quarterly, in January, April, July and October, by Elsevier. The mission of AP-SMART is to inspire clinicians, practitioners, scientists and engineers to work towards a common goal to improve quality of life in the international community. The Journal publishes original research, reviews, editorials, perspectives, and letters to the Editor. Multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines will be the trend in the coming decades. AP-SMART provides a platform for the exchange of new clinical and scientific information in the most precise and expeditious way to achieve timely dissemination of information and cross-fertilization of ideas.
