PURPOSE The aim of the present study was to compare the mechanical behavior of some devices used for femoral fixation of doubled hamstring tendon graft in anterior cruciate ligament (ACL) reconstruction when included in a graft fixation complex (GFC). METHODS An ACL reconstruction was performed on 90 porcine knees. The graft used was the doubled lateral(More)
Twenty-seven adolescents with anterior knee pain with or without patellar instability were studied by computerized tomography to detect patellofemoral malalignment. The examination was performed with and without quadriceps contraction with the knee flexed to 15 degrees. Congruence angle, patellar tilt angle, sulcus angle, and trochlear depth were measured.(More)
We performed intra-articular reconstruction of the anterior cruciate ligament (ACL) with the semitendinosus tendon placed in 2 mm diameter tunnels in 21 skeletally immature rabbits. The operation caused 11% damage to the physis of the femur on the frontal plane and 3% of its cross-sectional area but no alteration of growth or axial deviation of the bone(More)
PURPOSE The purpose of this study was to compare the results of arthroscopic and open repair of isolated Bankart lesions of the shoulder using metallic suture anchors. TYPE OF STUDY Prospective randomized clinical study. METHODS Sixty patients with traumatic anterior shoulder instability underwent a surgical repair of an isolated Bankart lesion. The(More)
PURPOSE The purpose of this study was to compare the clinical outcome of arthroscopic rotator cuff repair with single-row and double-row techniques. METHODS Eighty patients with a full-thickness rotator cuff tear underwent arthroscopic repair with suture anchors. They were divided into 2 groups of 40 patients according to repair technique: single row(More)
The purpose of this study was to evaluate prospectively the results of anterior cruciate ligament (ACL) reconstruction with doubled hamstring tendon graft in a selected group of 18 rugby players. The graft was fixed with a transcondylar screw (Transfix) on the femur, and with an absorbable interference screw and a metallic staple on the tibia. All the(More)
To evaluate the intra-observer and interobserver reliability of the ‘Pico’ computed tomography (CT) method of quantifying glenoid bone defects in anterior glenohumeral instability. Forty patients with unilateral anterior shoulder instability underwent CT scanning of both shoulders. Images were processed in multiplanar reconstruction (MPR) to provide an en(More)
BACKGROUND In lung cancer patients, metastases to soft tissues (STs), including skeletal muscle, subcutaneous tissue and skin, are rarely reported. Besides, lung cancer, primary carcinomas of the kidney and colon are the most commonly associated with ST metastases. AIM To determine the prevalence, clinical-pathological features and treatment options of ST(More)
The aim of this study was to compare the mechanical behavior under cyclic loading test of single-row and double-row rotator cuff repair with suture anchors in an ex-vivo animal model. For the present study, 50 fresh porcine shoulders were used. On each shoulder, a crescent-shaped full-thickness tear of the infraspinatus was performed. Width of the tendon(More)
