Although several devices for meniscal repairs have become available, a successful outcome is ultimately due to a healed meniscus on the clinical findings. The authors assessed the repair integrity after meniscal repair with the FasT-Fix device using second-look arthroscopy.
Meniscal repair with the FasT-Fix will lead to arthroscopically evident healing, but some menisci will show incomplete healing even in clinically successful cases and have newly formed injuries on the meniscal substance resulting from the path of the implant.
Case series; Level of evidence, 4.
Sixty-five consecutive patients were studied, in whom 84 menisci were subjected to all-inside meniscal repair with the FasT-Fix device in conjunction with anterior cruciate ligament reconstruction. Repair was only performed on longitudinal or double longitudinal tears within the red-red or red-white zone. The repaired menisci were evaluated by second-look arthroscopy at the time of staged hardware removal after anterior cruciate ligament reconstruction.
Sixty-two meniscal tears in 46 patients were available for this study. Eight patients were found to be symptomatic and considered to be clinical failures. The clinical success rate was 83%. At second-look arthroscopy, 46 tears (74%) were healed, 9 (15%) were healed incompletely, and 7 (11%) had failed. In the failed menisci, 1 had meniscal symptoms, while the other 6 were asymptomatic. In the 9 menisci with incomplete healing, 3 were associated with nonspecific knee pain but none showed meniscal symptoms. Newly formed injuries, which occurred in an area different from the original repair site, were confirmed on the surface of 19 menisci (35%) among the healed and incompletely healed menisci. Thirty menisci (48%) displayed successful and complete healing of the original tear site without newly formed tears.
Meniscal repair with the FasT-Fix in conjunction with anterior cruciate ligament reconstruction resulted in complete healing in 74% of cases. Eighty-three percent of menisci were symptom-free regardless of meniscal integrity. Even when the menisci repaired are asymptomatic and considered to be a clinical success, however, there may be newly formed injuries.
尽管已有多种半月板修复设备问世，但最终的成功仍取决于临床检查时半月板的愈合情况。作者使用关节镜对 FasT-Fix 半月板修复装置修复后的半月板完整性进行了评估。
使用 FasT-Fix 进行半月板修复将导致关节镜下可见的愈合，但即使在临床成功的情况下，一些半月板仍会显示不完全愈合，并且在植入物路径处的半月板实质上会出现新的损伤。
病例系列；证据水平，4 级。
研究了 65 例连续患者，其中 84 个半月板采用 FasT-Fix 全内半月板修复装置结合前交叉韧带重建术进行修复。仅对红-红区或红白区的纵向或双纵向撕裂进行修复。在前交叉韧带重建后分期取出内固定物时，通过关节镜再次检查修复的半月板。
46 例患者的 62 个半月板撕裂可用于本研究。8 例患者出现症状，被认为是临床失败。临床成功率为 83%。在关节镜再次检查时，46 个撕裂（74%）愈合，9 个（15%）愈合不完全，7 个（11%）失败。在失败的半月板中，1 个有半月板症状，而其他 6 个无症状。在愈合不完全的 9 个半月板中，3 个伴有非特异性膝关节疼痛，但均无半月板症状。在愈合和愈合不完全的半月板表面，有 19 个半月板（35%）确认有新的损伤，这些损伤发生在与原始修复部位不同的区域。30 个半月板（48%）在原始撕裂部位显示出完全愈合且无新的撕裂。
结合前交叉韧带重建术使用 FasT-Fix 进行半月板修复，74%的病例完全愈合。无论半月板完整性如何，83%的半月板无症状。然而，即使半月板修复后无症状且被认为是临床成功，也可能会出现新的损伤。
