Arthroscopic treatment of chronic patellar tendinopathy in high-level athletes.

To present the results of arthroscopic treatment of patellar tendinopathy in high-level competition athletes. Eleven high-level athletes presented chronic patellar tendinopathy which did not respond to long term conservative treatment. Average age of the patients was 24.

Residual malformations and leg length discrepancy after treatment of fibular hemimelia.

Background: Fibular hemimelia has been reported as the most common congenital longitudinal deficiency of the long bones. Previous studies have focused on the best treatment options for this congenital condition. There is very little to our knowledge in the literature focused on residual persisting malformations and leg length discrepancy after treatment.

Acromial morphology: effects of suboptimal radiographs.

Acromial morphology is one of the important factors related to rotator cuff pathology, especially if there is acromial encroachment onto the supraspinatus tendon. This is the rationale for many surgeons performing an acromioplasty, based on preoperative radiographs, in their treatment of rotator cuff disease. However, geometric measurements of the acromion are dependent on the radiographic view, and suboptimal radiographs of the scapula might bias the acromial morphology on the radiographs.

Healing and normal fibroblasts exhibit differential proliferation, collagen production, alpha-SMA expression, and contraction.

This study determines the differences in proliferation, collagen production, alpha-smooth muscle actin (alpha-SMA) expression, and contraction between healing and normal fibroblasts. Transected and sham-operated rat medial collateral ligaments (MCL) were used to obtain healing and normal fibroblasts, respectively. It was found that healing fibroblasts in monolayer culture proliferated 1.

Decreasing inflammatory response of injured patellar tendons results in increased collagen fibril diameters.

Tissue inflammation is essential in the healing process, but its effect on the quality of the healing tissue is not clear. This study determines the effect of decreasing early inflammation during wound healing in genetic deficient mice on collagen fibril diameter. Two strains of mice were used: three C3H/HeJ mice and three C3H/HeN mice for each of two time points (7 and 14 days postinjury).

The effectiveness of reconstruction of the anterior cruciate ligament using the novel knot/press-fit technique: a cadaveric study.

Background: A variety of fixation devices are used for anterior cruciate ligament reconstruction with hamstring tendon grafts. These devices increase costs and can present artifacts in magnetic resonance imaging as well as complications in revision surgery. Therefore, a novel knot/press-fit technique that requires no implantable devices has been introduced.
