Randomized Controlled Trial Comparative Study
Osteochondral lesions of the talus: randomized controlled trial comparing chondroplasty, microfracture, and osteochondral autograft transplantation.
The purpose of this study was to compare outcomes of chondroplasty versus microfracture versus osteochondral autologous transplantation (OAT) in patients with osteochondral lesions of the talus (OLT). ⋯ Level I, Therapeutic study, high-quality randomized controlled trial with no statistically significant differences but narrow confidence interval.

To evaluate recently introduced sutures and suture anchors for single pull load to failure strength and failure mode. ⋯ Surgeons who prefer stronger sutures now have several high-strength suture options from which to choose. Most of the new anchors tested performed very well.

It was our intent to devise a new clinical test that would more accurately diagnose subscapularis tears than the current clinical tests. This new test is called the bear-hug test. The purpose of this study was to assess the bear-hug test and compare it with the current tests of subscapularis function (lift-off, belly-press, and Napoleon tests). ⋯ Level I, diagnostic study: testing of previously developed criteria in a series of consecutive patients with arthroscopy used as the criterion standard.

Arthroscopic repair of posterior shoulder instability is becoming an accepted method of treatment. Most surgeons perform this procedure with the patient in a lateral decubitus position to facilitate access to the posterior glenoid. We have developed an accessory portal placed through the midportion of the rotator cuff that allows easy and complete viewing of the posterior glenohumeral joint when the patient is in a beach chair position and does not require the use of traction. ⋯ Through this approach, we were able to place 3 anchors, with the lowest at the 7 o'clock position (for a right shoulder), in all patients. Mean American Shoulder Elbow Surgeons (ASES) score improved from 53 +/- 15 preoperatively to 87 +/- 8 postoperatively (P < .01). All patients had an excellent result with complete resolution of pain and instability.

The purpose of this study was to evaluate the arthroscopically assisted Bristow-Latarjet procedure. The aim was to use arthroscopic guidance to assist in positioning of the coracoid bone block onto the anterolateral aspect of the glenoid. The feasibility of this technique and its efficacy, reproducibility, and potential neurovascular complications were evaluated. ⋯ This cadaveric study highlights the advantages offered by an arthroscopically assisted Bristow-Latarjet procedure, which optimizes positioning of the block and ensures adequate reaming of the anterior glenoid, thereby potentially reducing the risks of early nonunion and late arthritis--complications commonly associated with the classical Bristow-Latarjet technique.
