BACKGROUND
The purpose of this study was to investigate the outcomes of surface replacement arthroplasty (SRA) for noninflammatory arthritis of the metacarpophalangeal (MCP) joint.
METHODS
Records from 20 SRAs performed between 1995 and 2017 in 17 patients with noninflammatory arthritis affecting the MCP joint were retrospectively reviewed. The mean follow up was 6.6 years.
RESULTS
Three arthroplasties (15%) underwent 4 revision operations. The 2-, 5-, 10-, and 15-year rates of survival from surface replacement implant revision were 90%, 90%, 79%, and 79%, respectively. Major complications occurring in revised joints included arthrodesis (n = 1) and amputation (n = 1). The overall reoperation rate was 35%. The 2-, 5-, 10-, and 15-year rates of overall reoperation-free survival were 75%, 69%, 60%, and 60%, respectively.
CONCLUSIONS
Pain ratings and MCP arc of motion significantly improved following arthroplasty. Metacarpophalangeal SRA for noninflammatory arthritis can improve arc of motion and pain. Revision is uncommon; however, 1 in 3 joints requires reoperation.
背景
本研究旨在调查掌指关节（MCP）非炎性关节炎的表面置换关节成形术（SRA）的疗效。
方法
回顾性分析1995年至2017年间对17例患有影响MCP关节的非炎性关节炎患者实施的20例SRA记录。平均随访时间为6.6年。
结果
3例关节成形术（15%）进行了4次翻修手术。表面置换植入物翻修后的2年、5年、10年和15年生存率分别为90%、90%、79%和79%。翻修关节出现的主要并发症包括关节融合术（n = 1）和截肢（n = 1）。总体再手术率为35%。2年、5年、10年和15年无再手术生存率分别为75%、69%、60%和60%。
结论
关节成形术后疼痛评分和MCP活动弧度显著改善。用于非炎性关节炎的掌指关节SRA可改善活动弧度和疼痛。翻修不常见；然而，每3个关节中有1个需要再次手术。
