Complications have been described with each technique for reconstruction of the anterior cruciate ligament (ACL) in the knee, both open and arthroscopically assisted. The authors describe a case of tibial plateau fracture occurring 7 months after an ACL reconstruction using the half tunnel technique. ⋯ To our knowledge, only 2 cases of proximal tibial fracture after patellar tendon autograft ACL reconstruction have been previously reported. The authors hypothesize that patellar tendon harvesting with bone blocks and transosseous tibial tunnel can produce a "stress riser" effect and somehow act synergistically to create decreased strength at the level of proximal tibial metaphysis.

We placed the tibial tunnel arthroscopically in 10 cadaveric knees using a standard tibial drill guide. Accurate tibial tunnel position was documented in each knee by lateral radiograph. A 4.5-mm bicortical drill hole was placed perpendicular to the tibial surface 1 cm distal to the tibial tunnel. The distances from the posterior tibial drill exit point to nearby neurovascular structures were measured with a caliper. ⋯ Bicortical drilling for fixation of soft tissue grafts appears reasonably safe. The structures at greatest risk for injury are the bifurcation of the popliteal artery/vein and the anterior tibial vein.

The purpose of this report is to describe the biceps load test II for evaluating the superior labral anterior and posterior (SLAP) lesions. ⋯ The biceps load test II is an effective diagnostic test for SLAP lesions.

The purpose of this study was to document the incidence of lesions of the rotator interval, illustrate the arthroscopic appearance of subtle differences in these lesions, and discuss how various lesions may affect biceps tendon stability in the bicipital groove. ⋯ This study has recorded the incidence of lesions of the subscapularis, SGHL/MCHL complex and/or the LCHL, and combinations thereof in degenerative cuff and instability patients. Primary lesions of the rotator interval can occur and regardless of the associated pathology, and if these lesions are not repaired, biceps tendon subluxation may exist.

Digitally assisted acromioplasty: the effect of interscalene block on this new surgical technique.
Interscalene brachial plexus (ISBP) block has been shown to be safe and effective for shoulder surgery with significant benefits. The purpose of this study was to introduce the technique of digitally assisted acromioplasty and assess the effect of ISBP on rehabilitation. ⋯ ISBP provides superior initial results but does not offer any significant persistent functional or rehabilitative advantage in the medium to long term. Digitally assisted acromioplasty is simple to perform and does not violate the deltoid insertion.
