Unicompartmental knee arthroplasty has been associated with faster recovery with less potential perioperative morbidity compared to total knee arthroplasty. This study investigates the rate of transfusion, symptomatic thromboembolic events, and length of hospital stay in 1000 consecutive, unicompartmental knee replacements performed by 2 surgeons. A rapid recovery protocol coupled with multimodal venous thromboembolism prophylaxis was used for all patients. Five patients (0.5%) received a blood transfusion for symptomatic postoperative anemia. One patient (0.1%) developed a symptomatic deep venous thrombosis within 90 days of follow-up. No patient experienced a symptomatic pulmonary embolism. Length of hospital stay averaged 1.4 days. Unicompartmental arthroplasty using less invasive surgical techniques, a rapid recovery protocol, and multimodal venous thromboembolism prevention is a safe and effective procedure associated with a low rate of morbidity.
与全膝关节置换术相比，单髁膝关节置换术恢复更快，围手术期发病风险更低。本研究调查了由两位外科医生连续进行的1000例单髁膝关节置换术中的输血率、有症状的血栓栓塞事件及住院时间。所有患者均采用快速康复方案并联合多模式静脉血栓栓塞预防措施。5例患者（0.5%）因术后有症状性贫血接受了输血。1例患者（0.1%）在随访90天内发生了有症状的深静脉血栓形成。没有患者发生有症状的肺栓塞。平均住院时间为1.4天。采用微创外科技术、快速康复方案和多模式静脉血栓栓塞预防措施的单髁关节置换术是一种安全有效的手术，发病率较低。
