METHODS We prospectively followed 176 patients for at least 24 mo who had been treated by unilateral, minimally invasive, Oxford UKA. Patients with medial osteoarthritis(OA) knee and preoperative GR(Group Ⅰ) accounted for 18%(n = 32) and patients without preoperative GR(Group Ⅱ) accounted for the remaining 82%(n = 144). Knee score, pain scores, and functional scores were assessed for each patient and compared between the two groups. The incidence of postoperative GRand the postoperative hyperextension angles also were recorded and analyzed. RESULTS The pain score, knee score and functional score were not significantly different between the two groups. Similarly, the incidence of postoperative GR and the measured hyperextension angles were not significantly different between the two groups. The incidence of postoperative GR was 1/32(3.12%) in Group Ⅰ and 1/144(0.69%) in Group Ⅱ(P = 0.34). The mean postoperative hyperextension angles were 2.40°± 2.19°(range: 1°-7°) for Group Ⅰ and 1.57°± 3.51°(range: 1°-6°) for Group Ⅱ(P = 0.65).CONCLUSION Medial OA of the knee and concomitant GR is not a contraindication for the mobile bearing UKA.展开更多

A partial growth arrest at the anterior portion of the proximal tibial physis following a conservatively treated Meyers-McKeever type II injury of the tibial eminence. This is a reliable method in the correction of genu recurvatum. By using tricortical autogenous iliac crest graft, the osteotomy may be made very stable intra-operatively circumventing the need for fixation.展开更多
