چکیده

BackgroundSeveral risk factors for postoperative retear after arthroscopic rotator cuff repair (ARCR) have been cited in a large number of reports; various combinations these seem to be present the clinical setting.PurposeUsing combination model decision tree analysis, we aimed investigate that affect most.MethodsA total 286 patients who underwent magnetic resonance (MR) imaging at 6 months surgery were included this study. Based on structural integrity MR images taken surgery, divided into healed group (intact tendon, 254 patients) and (ruptured 32 patients). Using univariate analyses, selected 11 drastically affected retear.ResultsThe mean age was 64.9 ± 7.1 years, symptom duration 9.7 11.6 months.

The Factors Affecting Pain Pattern after Arthroscopic Rotator Cuff Repair

BACKGROUND We evaluated the factors that affect pain pattern after arthroscopic rotator cuff repair. METHODS From June 2009 to October 2010, 210 patients underwent arthroscopic rotator cuff repair operations. Of them, 84 patients were enrolled as subjects of the present study. The evaluation of postoperative pain was conducted by visual analog scale (VAS) scores during postoperative outpatien...

Arthroscopic repair of complete tear of rotator cuff

 Abstract  Background: Rotator cuff tear is one of the most common causes of shoulder  complaints in the elderly. Based on the severity and patient's condition, a variety of  methods applies to manage the tear and surgery is an important method, which could  be done by open or arthroscopic technique. The current study aimed to investigate  and report short-term results of arthroscopic repair of...

Risk factors for retear of large/massive rotator cuff tears after arthroscopic surgery: an analysis of tearing patterns

BACKGROUND Previous studies have evaluated the risk factors for retear of large/massive rotator cuff tears (RCTs) that were treated arthroscopically; however, most studies did not evaluate tear patterns. The present study hypothesized that postoperative risk factors are affected by the tearing patterns in large/massive cuff tears in patients undergoing arthroscopic rotator cuff repair (ARCR). ...

Arthroscopic rotator cuff repair.

Arthroscopic rotator cuff repair is being performed by an increasing number of orthopaedic surgeons. The principles, techniques, and instrumentation have evolved to the extent that all patterns and sizes of rotator cuff tear, including massive tears, can now be repaired arthroscopically. Achieving a biomechanically stable construct is critical to biologic healing. The ideal repair construct mus...
