ObjectiveTo review the research progress of treatment for massive rotator cuff tears. MethodsThe domestic and foreign literature about the treatment of massive rotator cuff tears was reviewed. The methods and effectiveness were extensively summarized.ResultsThe treatment of massive rotator cuff tears still needs long-term research to promote its continuous improvement. The main goal of treatment is to relieve the symptoms and improve the shoulder joint function. With the development of arthroscopic technique, arthroscopic repair of rotator cuff tears has become a mature surgical protocol. Among these techniques, superior capsule reconstruction and patch augmentation for massive rotator cuff tears acquire more attention in recent years. As for rotator cuff arthropathy, reverse shoulder arthroplasty is considered to be a final choice. ConclusionSurgical treatment is the main choice for massive rotator cuff tears. Patients’ age and muscle condition should be taken into consideration to decide the surgical technique.
ObjectiveTo investigate the effectiveness of partial anterior cruciate ligament (ACL) suture repair with wide awake local anesthesia no tourniquet (WALANT) technique.MethodsBetween July 2017 and July 2019, 18 patients with partial ACL injury were admitted. There were 10 males and 8 females, with an average age of 40.5 years (range, 22-57 years). There were 5 cases on the left knee and 13 cases on the right knee. Forteen cases had a clear history of trauma or sports injury, and 4 cases had no obvious cause. The time from injury to operation was 1-6 months (median, 3 months). Partial ligament was sutured using WALANT technique under arthroscopy. The operation time, total hospital stay, and postoperative hospital stay were recorded. Lachman test and anterior drawer test were performed to evaluate the knee joint stability after treatment, and Lysholm and International Knee Documentation Committee (IKDC) scores were used to evaluate the knee function. Five-point Likert scaling were used to evaluate postoperative patient satisfaction.ResultsThe operation time was 30-100 minutes (mean, 64.2 minutes). The total hospital stay was 2-12 days (mean, 4.5 days). Postoperative hospital stay was 1-4 days (mean, 1.8 days). All incisions healed by first intention after operation, and no surgery-related complications occurred. All patients were followed up 12-36 months (mean, 19.1 months). Lachman test and anterior drawer test were negative after operation. Lysholm score and IKDC score at 6 and 12 months after operation were significantly higher than those before operation, and at 12 months after operation were higher than those at 6 months after operation, the differences were significant (P<0.05). At last follow-up, according to five-point Likert scaling of patient satisfaction, 7 cases were very satisfied, 10 cases were relatively satisfied, and 1 case was general. The total patient satisfaction rate was 94.4% (17/18). MRI scan showed the good ligament tension.ConclusionUsing WALANT technique to repair partial ACL injuries under arthroscopy can retain the patient’s own ligament tissue to the maximum extent and achieve satisfactory short-term effectiveness.
