Fifty-eight patients who had undergone meniscal surgery were reviewed. Half had undergone conventional open meniscectomy, and half had been treated by arthroscopic meniscectomy. Each patient in the open group was matched with a patient in the endoscopic group by age, sex, and type of meniscal lesion. Patients with ligamentous injuries were excluded. Twelve patients in the endoscopic group were operated on as outpatients; the mean post-operative hospital stay in the 17 hospitalized patients in the endoscopic group was one day as compared with a mean of 3.3 days for the patients in the open group. Sick leave for the endoscopic group was only one-third of that of the open group. Operating time was 74.5 +/- 38.7 minutes in the open group compared with 55.9 +/- 25.0 minutes in the endoscopic group. At follow-up evaluation (mean follow-up period, 38 months) the percutaneous group showed a knee function score (88.7 points) similar to that of the open group (85.3 points) at 51 months. A three-year follow-up study of patients operated on endoscopically for a single meniscal lesion demonstrated that results with endoscopy are as satisfactory as those obtained by conventional surgery. Advantages of endoscopy include decreased hospitalization and shorter sick leave, with a corresponding reduction in the cost of patient care.
对58例接受半月板手术的患者进行了回顾性研究。其中一半患者接受了传统开放式半月板切除术，另一半接受了关节镜下半月板切除术。开放式手术组的每位患者均与关节镜手术组的患者在年龄、性别和半月板损伤类型上进行了匹配。排除伴有韧带损伤的患者。关节镜手术组中有12例患者作为门诊病人接受手术；关节镜手术组中17例住院患者的术后平均住院天数为1天，而开放式手术组患者的平均住院天数为3.3天。关节镜手术组的病假天数仅为开放式手术组的三分之一。开放式手术组的手术时间为74.5±38.7分钟，而关节镜手术组为55.9±25.0分钟。在随访评估中（平均随访期为38个月），关节镜手术组在51个月时的膝关节功能评分（88.7分）与开放式手术组（85.3分）相似。一项对因单一半月板损伤接受关节镜手术患者的三年随访研究表明，关节镜手术的结果与传统手术一样令人满意。关节镜手术的优点包括住院时间缩短、病假天数减少，相应地降低了患者护理成本。
