ABSTRACT
BACKGROUND: With an increase in the treatment options available for massive rotator cuff tears, understanding the long-term outcomes of the chosen modality is important. QUESTIONS/PURPOSE: The purpose of this study was to systematically review the available literature on repair of massive rotator cuff repairs and learn the longevity of outcomes, the failure rate, outcomes after failure, and any contributing factors to poor outcomes or failure. METHODS: We conducted a systematic review of the MEDLINE, Cochrane, and Embase databases to find studies that investigated the long-term results of repair of massive rotator cuff repairs. Studies were excluded if they did not stratify results of massive tears, provide a definition for a massive rotator cuff tear, or report isolate patients with long-term follow-up. RESULTS: Six studies met the inclusion criteria, for a total of 472 shoulders; average patient age was 57.6 years. Follow-up ranged from 119 to 240 months. Outcome scores improved significantly following repair and were maintained throughout follow-up. The repair failure rate across studies was 39.2%. Patients who suffered retear had significantly worse outcome scores than patients with intact tendons at long-term follow-up. CONCLUSIONS: The existing literature on long-term follow-up after massive rotator cuff repair is scarce and not of high level of evidence. This review found repair of massive rotator cuff tears leads to long-term maintained improvements in outcome measures. Failure of repair is quite common, but results following failure are superior to preoperative outcomes.
ABSTRACT
PURPOSE: To report current data on return-to-sport rates and sports-specific patient-reported outcomes after osteochondral allograft (OCA) transplantation for cartilage defects of the knee. METHODS: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines that included studies from 1975 to 2018 with a minimum 2-year mean follow-up that reported return-to-sport rates or sports-specific patient-reported outcomes. Outcomes, reoperations, and complications were provided in table format, and a subjective analysis was performed. RESULTS: This review included 13 studies with 772 patients who underwent OCA transplantation at a mean of 24 to 91 months' follow-up. The return-to-sport rate ranged from 75% to 82%. For patient-reported outcomes, the Knee Injury and Osteoarthritis Score Sport increased in 4 studies, the Tegner activity scale score increased in 3 studies but decreased in 1, and the Marx activity scale score increased in 1 study but decreased in 2. Studies reporting improvements in the Cincinnati Knee Score and Knee Injury and Osteoarthritis Score Sport reached the minimal clinically important difference. The reoperation rate was high (ranging from 34% to 53% in more than half of studies), with reoperations primarily performed for loose body removal or debridement. CONCLUSIONS: This systematic review of 13 studies suggests that OCA transplantation for cartilage defects allows most athletes to return to sport (range, 75%-82%). Most studies reported improvements in sports-specific patient-reported outcomes at follow-up and reached the minimal clinically important difference. However, the reoperation rate was high in several studies, with a large percentage of patients requiring loose body removal or debridement. The long-term survival of the allografts is largely unknown, but this study suggests OCA transplantation consistently improves function in athletes with chondral injuries. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and IV studies.
