■先前的研究表明,就患者报告的结果而言,内侧半月板后根撕裂(MMPRT)修复优于清创术,全膝关节置换术(TKA)的转换率,和长期成本。尽管已知中期结果不佳,对于退行性MMPRTs,半月板部分切除术的长期结果很少.
■目的1)评估接受MMPRTs部分内侧半月板切除术(PMM)患者的长期患者报告和影像学结果,和2)确定转换为全膝TKA的比率和危险因素。
■案例系列;证据级别,4.
■在2005年至2013年期间,先前确定的26例接受半月板部分切除术治疗的患者队列在至少10年的随访中对长期结局进行了前瞻性随访。对患者进行国际膝关节文献委员会(IKDC)结果评分评估,再操作,并转换为TKA。失败定义为转换为关节成形术或严重异常的IKDC主观评分<75.4。
■这项研究包括26名患者(10名男性,16名妇女;平均年龄,54±8.7年[范围,38-71岁]诊断时;体重指数,32.9±5.5),平均随访14.0±3.6年(范围,10.1-19.6年)。在最后的后续行动中,1例患者死亡,其余25例患者中有18例(72%)进展为TKA,1例(4%)患者接受重复半月板切除术。6例(24%)未进行TKA或翻修手术的患者报告的平均IKDC评分为57±23。19例患者接受了后续手术,5例患者表现出严重异常的IKDC评分,导致平均14年随访时的临床失败率为96%(25例活着的患者中有24例)。
■在至少10年的随访中,根据主观临床结果,用于治疗内侧半月板后角根部撕裂的PMM显示72%进展为TKA,96%失败。
UNASSIGNED: Previous studies have demonstrated that medial meniscus posterior root tear (MMPRT) repair is superior to debridement in terms of patient-reported outcomes, rates of conversion to total knee arthroplasty (TKA), and long-term costs. Despite the known poor midterm outcomes, there is a paucity of long-term results of partial meniscectomy for degenerative MMPRTs.
UNASSIGNED: To 1) evaluate long-term patient-reported and radiographic outcomes of patients who underwent partial medial meniscectomy (PMM) for MMPRTs, and 2) determine the rate of and risk factors for conversion to total knee TKA.
UNASSIGNED: Case series; Level of evidence, 4.
UNASSIGNED: A previously identified cohort of 26 patients treated with partial meniscectomy for isolated MMPRTs between 2005 and 2013 was prospectively followed for long-term outcomes at a minimum 10-year follow-up. Patients were evaluated for International Knee Documentation Committee (IKDC) outcome score, reoperation, and conversion to TKA. Failure was defined as conversion to arthroplasty or a severely abnormal IKDC subjective score <75.4.
UNASSIGNED: This study included 26 patients (10 men, 16 women; mean age, 54 ± 8.7 years [range, 38-71 years] at diagnosis; body mass index, 32.9 ± 5.5) who were followed for a mean of 14.0 ± 3.6 years (range, 10.1-19.6 years). At the final follow-up, 1 patient was deceased and 18 (72%) of the remaining 25 patients had progressed to TKA, with 1 (4%) patient undergoing repeat meniscectomy. The 6 (24%) patients who had not progressed to TKA or revision surgery reported a mean IKDC score of 57 ± 23. Nineteen patients underwent subsequent surgery and 5 demonstrated severely abnormal IKDC scores resulting in a clinical failure rate of 96% (24 of the 25 living patients) at a mean 14-year follow-up.
UNASSIGNED: PMM for medial meniscus posterior horn root tears demonstrated 72% progression to TKA and 96% failure according to subjective clinical outcomes at a minimum 10-year follow-up.
