摘 要: | Objective To explore the indication and observe short-term clinical outcome of the medial Oxford Ⅲ mobile bearing unicompartmental knee replacement (UKR) through a minimal invasive approach for the patients with osteoarthritis of the knee. Methods A retrospective study of the clinical outcomes from May 2006 to May 2008 was done on 30 knees in 21 patients after receiving the UKR with the mobile bearing Oxford Ⅲ prosthesis. There were 9 males (12 knees), 12 females (18 knees), with the mean age of (61.4±7.3) years (ranged 46-76 years). All patients were evaluated pre and postoperatively using X-ray image, the Knee Society Score (KSS) and the WOMAC osteoarthritis index and examined the ROM and the varus deformity of the knee with osteoarthritis. Results The average follow-up time was 17 months. The mean operation time was (83.0±12.9) min and the mean hospital stay was (9.3±2.0) days. No complications of infection, thrombosis, mobile beating dislocation were found. The loss of flexion of the operated knee was not significant. The average femorotibial angle decreased from 182.0°±4.3° preoperatively to 177.0°±3.5° postoperatively in the anterioposterior view of X-ray. The KSS clinical score and function score were improved from average 44.0±3.7 and 54.0±5.1 to 93.0±3.2 and 92.0±2.4 respectively. The WOMAC Score was average 48.0±4.2 preoperatively, 14.0±2.5 at the last evaluation. Statistically significant differences were found pre and postoperatively from the aforementioned evaluation criterions. Conclusion The short-term clinical outcomes of medial Oxford Ⅲ mobile bearing UKR through a minimally invasive approach are ideal, and it is a good therapy choice for the patients with medial osteoarthritis of the knee. But it is also important to choose the suitable patients with indications.
