Autogenous bone grafting for chronic anteroinferior glenoid defects via a complete subscapularis tenotomy approach.
Open reconstruction of severe anteroinferior chronic glenoid defects via a complete subscapularis (SSC) tenotomy using a tricortical iliac crest bone grafting technique has been reported. The purpose of this study was to evaluate the clinical and radiological results in patients who underwent this procedure and to investigate the influence of the anterior approach on the structure and function of the SSC musculotendinous unit. ⋯ Open reconstruction of anteroinferior chronic glenoid defects via a complete SSC tenotomy using an iliac crest bone grafting technique allows an anatomic reconstruction of the anteroinferior glenoid with good and excellent clinical results. The anterior approach may lead to atrophy and fatty infiltration of the SSC muscle despite an intact tendon. However, this did not affect the results in terms of stability.

Autologous chondrocyte implantation for the treatment of retropatellar cartilage defects: clinical results referred to defect localisation.
Although autologous chondrocyte implantation (ACI) has become well established for the treatment of full-thickness cartilage defects of the knee joint, nevertheless clinical results of retropatellar lesions are still inferior compared to those of defects located on femoral condyles. We report the clinical results obtained in 70 patients treated with ACI for full-thickness defects of the patella, with special reference to defect location and size, age, body mass index and sports activity. ⋯ This study demonstrates that within a group of patients treated with ACI for retropatellar cartilage lesion there are significant differences in clinical outcome, which are important and should be taken into account of when a decision has to be made on whether or not ACI is indicated.

Trantibial anterior cruciate ligament double bundle reconstruction technique: two tibial bundle in one tibial tunnel.
The anterior cruciate ligament (ACL) consists of two functional bundles that behave independently throughout the range of knee motion. Many two-bundle reconstruction techniques have been introduced to restore the function of the two bundles of the ACL. Generally, two femoral and two tibial tunnels are made during the surgery for a two-bundle ACL reconstruction. ⋯ The two bundles in a single tibial tunnel are separated using biodegradable interference screw. Stable and adequate femoral fixation of the two bundles with a transtibial fixation and bioabsorbable screw can be obtained. This technique is relatively simple, and replicates the anatomy and differential behavior of the two native bundles of ACL more effectively.

A simple and effective technique of femoral tunnel bone grafting in revision anterior cruciate ligament reconstruction.
Restoring the bone stock in the femoral tunnel during revision anterior cruciate ligament reconstruction is vital for better surgical results and to avoid potential complications. The technique must be easy, effective, simple, reproducible and cost effective. We describe a new, simple and inexpensive technique of femoral tunnel bone grafting in revision ACL reconstruction using universally available materials.
