文题释义:
膝关节单髁置换:指仅对膝关节早期单间室骨性关节炎进行单侧病变间室表面置换,用以替代膝关节胫股关节破坏的软骨表面。具有失血少、创伤小、恢复快、最大限度保留骨量、费用低、并发症少和患者满意度高等优点。只要严格把握适应证,无论是固定平台还是活动平台单髁膝关节假体的中长期生存率都可以和全膝关节置换假体媲美。
膝内侧单间室骨性关节炎:好发于中老年人,疾病是以慢性、进展性、退行性为特征的关节无菌性炎症,致病因素主要是膝关节机械应力分布失衡,导致负荷过度引起软骨磨损退变,病变可累计单间室和多间室,早期以单间室病变为主,内侧间室更为多见的疾病。
 
摘要
背景:单髁置换治疗膝单间室骨性关节炎具有失血少、创伤小、恢复快、最大限度保留骨量、费用低、并发症少和患者满意度高等优点,但是对于活动平台和固定平台单髁假体的选择问题目前还存在争议。
目的:对比LINK固定平台与Oxford活动平台假体单髁置换治疗膝内侧单间室骨性关节炎在解除膝关节疼痛、重建膝关节功能、纠正膝关节畸形方面的差异,为临床更好的选择假体提供依据。
方法:回顾性分析2014年12月至2016年6月广东省中医院关节科收治的单髁置换治疗膝内侧单间室骨性关节炎患者90例,按假体类型分为LINK固定平台组和Oxford活动平台组,每组45例。对2组患者术前术后疼痛程度、膝关节活动度、并发症、下肢力线进行评估;同时采用美国膝关节协会评分(KSS)对2组患者关节活动度、关节功能进行评价。
结果与结论:①无论选择活动平台型假体还是固定平台型假体,术后均能取得良好的临床疗效:②2组间KSS评分、目测类比评分、膝关节活动度对比差异均无显著性意义(P > 0.05);③2组患者术后均未出现深静脉血栓、假体松动、关节翻修等并发症;④2组患者在下肢力线矫正角度方面,差异有显著性意义(P < 0.05),活动平台组胫股角的矫正角度比固定平台大;⑤结果说明,在严格掌握适应证的前提下,LINK固定平台与Oxford活动平台假体单髁置换治疗膝关节单间室骨性关节炎均能够有效缓解患者痛苦,改善膝关节功能。虽然活动平台假体在恢复下肢正常力线方面更有优势,但也可能加速外侧软骨的磨损。

Abstract:

 BACKGROUND: In the treatment of unicompartmental knee osteoarthritis, unicompartmental knee arthroplasty has the advantages of less blood loss, less trauma, quick recovery, maximum retention of bone mass, low cost, fewer complications and higher patient satisfaction. However, for the mobile bearing and the fixed bearing, the choice of single condylar prosthesis is till controversial.

OBJECTIVE: To investigate the difference of LINK fixed-bearing and Oxford mobile-bearing unicompartment arthroplasty in relieving knee joint pain, reconstruction of the knee joint function, correct the knee joint deformity for medial unicompartment knee osteoarthritis, thus providing the basis for selecting a better prosthesis.
METHODS: Ninety patients with medial unicompartment knee osteoarthritis undergoing unicompartmental knee arthroplasty in the Department of Joint Surgery, Guangdong Provincial Hospital of TCM from December 2014 to June 2016 were analyzed retrospectively, followed by allotted into Oxford mobile-bearing and LINK fixed-bearing groups (n=45 per group). The preoperative and postoperative pain level, range of motion of the knee, complications, and limb alignment were assessed. The range of motion and function of the knee were evaluated by Knee Society Score system.
RESULTS AND CONCLUSION: (1) The two kinds of prosthesises both could obtain good clinical effectiveness. (2) There was no significant difference in the Knee Society Score, Visual Analogue Scale scores, or the range of motion of the knee between two groups (P > 0.05). (3) No complications such as deep vein thrombosis, prosthesis loosening and joint revision were found in both groups. (4) The correction of limb alignment showed significant difference between two groups (P < 0.05). The corrective femorotibial angle in the Oxford mobile-bearing group was larger than that in the LINK fixed-bearing group. (5) These findings manifest that under the precondition of strictly mastering the indications, both fixed-bearing and Oxford mobile-bearing unicompartment arthroplasties can effectively relieve the pain and improve the function of knee joint in the treatment of unicompartmental knee osteoarthritis. Oxford mobile-bearing prosthesis exhibits advantage in restoring the limb alignment; the movable platform lower limb alignment correction angle is often bigger than fixed platform correction angle, but may accelerate the lateral cartilage wear.
