The safe zone for femoral cross-pin fixation: an anatomical study.

Femoral cross-pin fixation in anterior cruciate ligament (ACL) reconstruction has a potential for neurovascular injury, thus a "safe zone" must be defined for safe pin passage with this technique. In this anatomic study, femoral-sided, arthroscopic-assisted ACL reconstruction using the TransFix system (Arthrex, Naples, Fla) was performed on five fresh extended thigh and lower leg cadavers. Using a goniometer, five cross-pin guidewires were sequentially drilled at 0 degrees, -20 degrees, -40 degrees, +20 degrees, and +40 degrees, using the parallel to floor line as 0 degrees.

Fluid temperatures during radiofrequency use in shoulder arthroscopy: a cadaveric study.

Cadaveric shoulders underwent thermal capsulorrhaphy and subacromial decompression with 3 different commercially available radiofrequency (RF) devices to evaluate local and regional fluid temperatures while arthroscopic procedures were being performed. Fifteen completely thawed fresh-frozen shoulders underwent both thermal capsulorrhaphy and subacromial decompression. During thermal capsulorrhaphy, Fluoroptic mini-thermometer probes (Luxtron model 3000) were placed in the inflow bag; in the glenohumeral joint, near the inferior glenohumeral ligament; and on the RF wand.

The insertional footprint of the rotator cuff: an anatomic study.

Purpose: The purpose of this study was to define the entire rotator cuff footprint and relate it to known, easily identifiable landmarks as a guide for both open and arthroscopic rotator cuff repair. Anatomic: Gross and microscopic.

Methods: The myotendinous units of the rotator cuff and their insertions onto the humerus were dissected in 20 fresh-frozen cadavers.

The biomechanical effects of low-dose irradiation on bone-patellar tendon-bone allografts.

Background: Despite evidence that low-dose irradiation of 2 Mrad (20 kGy) is not virucidal for patellar tendon allografts and reduces tissue strength, many tissue bank protocols include low-dose irradiation.

Hypothesis: Maintaining tissue mechanical integrity may be particularly relevant toward accelerated rehabilitation of the injured knee, where the cyclic function of patellar tendon allografts is critical.

Study Design: Controlled laboratory study.

Arthroscopic posterior cruciate ligament repair for acute femoral "peel off" tears.

Posterior cruciate ligament (PCL) injuries can be associated with acute and chronic morbidity. Treatment of PCL disruption is typically either nonoperative or reconstructive, using a graft substitute. We describe a minimally invasive arthroscopic technique for repair of acute PCL tears of the femoral origin.

Surgical treatment of Achilles tendinitis by decompression of the retrocalcaneal bursa and the superior calcaneal tuberosity.

Background: Initial nonoperative treatment of pain at the Achilles tendon, often referred to as "tendinitis," is not always successful.

Hypothesis: Surgical treatment is effective for patients with insertional tendinitis unrelieved by nonoperative measures.

Study Design: Retrospective cohort study.
