The early and mid-term clinical efficacy of Oxford unicompartmental knee arthroplasty for the treatment of elder patients with medial compartmental knee osteoarthritis

Objective To investigate the early and mid-term clinical efficacy of Oxford unicompartmental knee arthroplasty(UKA) for the treatment of elder patients with medial compartmental knee osteoarthritis. Methods Fifty-two patients with medial compartmental knee osteoarthritis were treated by UKA retrospectively from July 2015 to July 2019 in the Department of Orthopedics, Yucheng People''s Hospital. Preoperative and postoperative knee range of motion (ROM), knee society score (KSS) and the visual analogue scale (VAS) were compared to evaluate the clinical efficacy. Results Fifty-two patients were successfully operated. All the patients were followed up for 3-24 months. Compared with preopration, the average ROM and KSS were significantly increased three months after operation(P<0.05), the average VAS was significantly decreased three months after operation(P<0.05). Dislocation of spacers occurred in two patients six months after operation.One case of manual reduction was successful, another case was successfully reset after replacing the thickened spacer.One patient developed intermuscular thrombosis six weeks after operation and the thrombosis was absorbed after anticoagulant therapy. No prothesis loosening or fracture was found. No infection or deep vein thrombosis occurred in any patient. Conclusion Oxford UKA is an effective method to treat medial compartmental knee osteoarthritis with the advantages of less invasion and rapid rehabilitation.
