摘要
目的探讨第3代Oxford单髁假体安放位置对人工单髁关节置换术(unicompartmental knee arthroplasty,UKA)近期疗效的影响。方法将2015年9月—11月收治并符合标准的26例(26膝)膝关节前内侧骨关节炎患者纳入研究,其中15例采用单柱型假体(单柱组)、11例采用双柱型假体(双柱组)行UKA。两组患者性别、年龄、体质量指数、骨关节炎Kellgren-Lawrence分级和术前美国特种医院(HSS)评分等一般资料比较,差异均无统计学意义(P>0.05)。随访时功能评价采用HSS评分、美国西部Ontario与McMaster大学骨关节炎评分(WOMAC)、牛津膝关节评分(OKS)和美国膝关节学会评分(KSS);组件安放位置评价采用Oxford单髁假体影像学评分,同时记录衬垫脱位等并发症发生情况。结果单柱组随访时间为24~27个月,平均26.2个月;双柱组随访时间为24~26个月,平均25.2个月。术后仅双柱组2例出现衬垫脱位。末次随访时,两组膝关节功能HSS评分、WOMAC评分、OKS评分、KSS评分比较,差异均无统计学意义(P>0.05)。X线片测量示两组股骨组件、胫骨组件以及总体组件影像学评分比较,差异均无统计学意义(P>0.05)。相关分析示,两组假体位置和术后关节功能间无相关性(P>0.05)。结论在一定安全范围内,第3代Oxford单髁假体安放位置对UKA近期疗效无明显影响。
Objective To investigate the effect of accuracy of phase 3 Oxford prosthesis positioning on shorttermeffectiveness of unicompartmental knee arthroplasty (UKA). Methods The clinical data of 26 patients (26 knees)who were treated with UKA between September 2015 and November 2015 was retrospectively analyzed. The single-pegOxford prosthesis was implanted in 15 patients (single-peg group), and twin-peg Oxford prosthesis was implanted in 11patients (twin-peg group). There was no significant difference in gender, age, body mass index, Kellgren-Lawrencegrading, and preoperative Hospital for Special Surgery (HSS) scores between 2 groups (P>0.05). HSS, knee society score(KSS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and Oxford knee score (OKS) wereused to evaluate the knee function. Radiographic criteria for Oxford UKA was used to evaluate the prosthesis position.The reason and treatment of bearing dislocations were recorded. Results All patients were followed up with meanfollow-up time of 26.2 months in single-peg group (range, 24-27 months) and 25.2 months in twin-peg group (range, 24-26 months). The bearing dislocation occurred in 2 cases of twin-peg group during follow-up. At last follow-up, there wasno significant difference in HSS, WOMAC, OKS, and KSS scores between 2 groups (P>0.05). There was no significantdifference in radiographic scores of femoral component, tibial component, and overall components between 2 groups(P>0.05). No significant correlation was found between radiographic scores and postoperative functional outcome in2 groups (P>0.05). Conclusion Within a safe range, the accuracy of phase 3 Oxford prosthesis positioning has limitedinfluence on the short-term functional outcome.
