Functional outcome of arthroscopic rotator cuff repair
ABSTRACT Introduction:Functional outcome after rotator cuff reconstruction is influenced by several factors of which re-rupture is probably the most important. Aim: The aim of the study was to evaluate the postoperative outcome including re-rupture rate after arthroscopic rotator cuff reconstruction. Method: 23 shoulders of 22 patients were examined prospectively. Physical examination, ultrasound and radiography were performed. Quality of life and functional outcome were evaluated using Constant Score and Visual Analog Scale. Results: Excellent or good results were found in 80% of the patients. The Constant Score has increased from 45 to 79, and the level of pain decreased from 6.6 to 2.5. Full-thickness rotator cuff tear was absent, but partial tear occurred in 7 cases (30%). Average acromiohumeral distance in the operated side was 8.5 mm compared to 9.5 mm measured on the contralateral shoulder. Conclusions: Arthroscopic rotator cuff repair is a safe and reliable procedure that provides good results. Orv. Hetil., 2014, 155(16), 620-626.

ABSTRACT: The purpose of this study was to identify the incidence of metallic suture anchor pullout after arthroscopic rotator cuff repair and determine the impact of tear size on the risk of pullout. A retrospective review of 269 patients (550 metallic suture anchors) who underwent arthroscopic rotator cuff repair between January 2006 and January 2009 was conducted. Inclusion criteria included patients aged 18 years or older, a minimum of 6 weeks' radiographic follow-up, and the use of 1 or more metallic suture anchors for partial or complete rotator cuff repair. The mean age of the cohort at the time of surgery was 55 years (range, 29 to 86 years), and there were 189 men and 80 women. Early anchor pullout occurred in 6 patients (9 anchors). The overall incidence of early metallic suture anchor pullout in this cohort was 2.4% (95% confidence interval, 0.5% to 4.3%). The incidence in rotator cuff tears less than or equal to 3 cm was 0.5%, and the incidence in tears greater than 3 cm was 11%. Patients undergoing arthroscopic rotator cuff repair of a tear greater than 3 cm in size were at a significantly higher risk of having early metallic suture anchor pullout than patients undergoing repair of a smaller tear (relative risk, 22; P = .001). Among the 61 patients undergoing arthroscopic subscapularis repair, no suture anchor failures were observed at the lesser tuberosity. Of the 9 anchors that failed, 8 (89%) pulled out of the posterior aspect of the greater tuberosity. There is a minimal risk of suture anchor pullout in small- to medium-sized tears; however, this risk increases with larger tear sizes. We recommend routine radiographic follow-up after use of metallic anchors to ensure identification of early failure by anchor pullout.

ABSTRACT: The aim of this study was to assess tendon healing and clinical results of rotator cuff tears (RCTs) repaired arthroscopically in patients aged 65 years or older. Between January 2001 and December 2004, 88 patients with a mean age of 70 years (range, 65 to 85 years) had arthroscopic RCT repair. The repair was performed on 54 women (61%). The dominant arm was involved in 72 patients (82%). RCT included more than 2 tendons in 45 cases. Functional outcomes were assessed by use of the Constant score and Simple Shoulder Test. Tendon healing was estimated by use of a computed tomography (CT) arthrogram, which was obtained 6 months postoperatively, and was classified into 3 categories: stage 1, watertight and anatomic healing; stage 2, watertight and partial healing; and stage 3, not watertight and retear. The mean duration of follow-up was 41 months (range, 24 to 77 months). The mean clinical outcome scores all improved significantly at the time of the final follow-up (P < .01). Computed tomography arthrogram imaging showed 27 shoulders with a stage 1 repair, 20 with a stage 2 repair, and 34 with a stage 3 repair. The retear rate was 42% (34 of 81). The patients with tendon healing stage 1 or 2 had a significantly superior functional outcome in terms of overall scores and strength compared with the stage 3 repairs (P < .01). In our study we had 39 isolated supraspinatus tears (small or medium tears); 11 (28.9%) had a retear (stage 3). Arthroscopic repair in patients aged 65 years or older can yield tendon healing resulting in significant functional improvement. Our data suggest that arthroscopic repair can be considered successful for the older patient specifically when the tear is limited to the supraspinatus tendon.

ABSTRACT: Suture bridge repair has been recognized to have superior biomechanical characteristics, as shown in previous biomechanical studies. However, it is not clear whether the tendon heals better in vivo after suture bridge repair. To evaluate the clinical results and repair integrity after arthroscopic rotator cuff repair using a suture bridge technique for patients with rotator cuff tears. Case series; Level of evidence, 4. One hundred twenty-three shoulders (120 patients) that underwent arthroscopic suture bridge repair for full-thickness rotator cuff tear were enrolled for this study. The mean duration of follow-up was 25.2 months (range, 16-34 months). The postoperative repair integrity was analyzed with use of magnetic resonance imaging (MRI) in 87 shoulders. According to the retear patterns on postoperative MRI, the cases were divided into type 1 (failure at the original repair site) or 2 (failure around the medial row). At the last follow-up, the University of California at Los Angeles (UCLA) score improved from the preoperative mean of 13.2 points to 29.7 points (P < .001). The rotator cuff was completely healed in 58 (66.7%) of the 87 shoulders, and there was a recurrent tear in 29 shoulders (33.3%). The incidence of retear tended to increase with age older than 60 years at the time of surgery (P = .002). When there was a larger intraoperative tear, the rate of retear was also higher (P = .002). When the severity of preoperative fatty degeneration of the cuff muscles was higher, there was a greater chance of a recurrent tear (P < .001). The retear patterns on postoperative MRI in 29 shoulders with recurrent failures were classified as type 1 in 12 shoulders (41.4%) and type 2 in 17 shoulders (58.6%). The preoperative cuff tear size did not have an influence on retear patterns (P = .236), but the percentage of type 1 retear increased with the severity of fatty degeneration or muscle atrophy (P = .041, .023). Arthroscopic suture bridge repair of full-thickness rotator cuff tears led to a relatively high rate of recurrent defects. However, the mean 25-month follow-up demonstrated excellent pain relief and improvement in the ability to perform the activities of daily living, despite the structural failures. The factors affecting tendon healing were the patient's age, the size and extent of the tear, and the presence of fatty degeneration in the rotator cuff muscle. The retear in cases with a suture bridge technique tended to be more frequently at the musculotendinous junction.The American Journal of Sports Medicine 02/2011; 39(10):2108-16.
