Ultrasound evaluation of arthroscopic full-thickness supraspinatus rotator cuff repair: single-row versus double-row suture bridge (transosseous equivalent) fixation. Results of a prospective, randomized study.

Background: The purpose of this study was to compare the structural outcomes of a single-row rotator cuff repair and double-row suture bridge fixation after arthroscopic repair of a full-thickness supraspinatus rotator cuff tear.

Material And Methods: We evaluated with diagnostic ultrasound a consecutive series of ninety shoulders in ninety patients with full-thickness supraspinatus tears at an average of 10 months (range, 6-12) after operation. A single surgeon at a single hospital performed the repairs.

The arthroscopic square knot: fiction or fact?

The square knot is the gold standard for open surgical knot tying. One criticism of arthroscopic shoulder surgery is that arthroscopic knots are not as secure as square knots tied during traditional open surgery. In this brief technical note, we describe a simple technique for tying arthroscopic square knots that the senior members of our group have been using in clinical practice for several years with successful results.

Glenoid component insertion in total shoulder arthroplasty: comparison of three techniques for drying the glenoid before cementation.

This prospective randomized study compared the immediate postoperative periglenoid radiolucencies among 3 glenoid-drying techniques used in total shoulder arthroplasty. Seventy-one consecutive patients with primary osteoarthritis underwent total shoulder arthroplasty by use of 1 prosthetic system with convex-back, keeled, polyethylene glenoid components; the same modern, instrumented pressurization technique was used to cement all glenoids. Of the shoulders, 21 had glenoid implants cemented after bony preparation with thrombin-soaked gel foam, 24 after compressed gas lavage, and 26 after saline solution lavage with sponge drying.

The arthroscopic square knot: a biomechanical comparison with open and arthroscopic knots.

Purpose: To compare the loop and knot security of arthroscopic square knots with other arthroscopic and open knots with the use of 2 commonly used suture types.

Methods: Five knot configurations were tested 12 times each. The arthroscopic square knot was compared with the open square knot, arthroscopic and open half hitches with alternating posts, and the Duncan loop.

Arthroscopic treatment of multidirectional glenohumeral instability: 2- to 5-year follow-up.

PURPOSE: We present the results of a prospective study evaluating arthroscopic technique in repairing multidirectional glenohumeral instability. Type of Study: Case series. METHODS: The 47 patient study group consisted of 26 men and 21 women.
