The Results of Oxford Unicompartmental Knee Arthroplasty in Patients With and Without Preoperative Genu Recurvatum

The purpose of this study is to explore the effects of the Oxford unicompartmental knee arthroplasty on two groups of patients, namely one with genu recurvatum before the procedure and one without. Specifically, this study compare the number of occurrences of postoperative genu recurvatum and the postoperative hyperextension angles among the patients. Additionally, the knee scores, the pain scores, and the functional scores for the two groups of patients are compared. Materials and methods: This study prospectively followed 104 patients (114 knees) who had been treated with cemented minimally invasive surgery unicompartmental knee arthroplasty and had had a minimum of 24 months of follow-up. The patients were divided into two groups: those without preoperative genu recurvatum (85 patients; 94 knees) and those with preoperative genu recurvatum (19 patients; 20 knees). The incidence of the postoperative genu recurvatum, the postoperative hyperextension angles, the knee scores, the pain scores, and the functional scores were recorded and compared between two groups..
