PURPOSE To evaluate the stability and arthrosis of the knee 10 to 15 years after arthroscopic-assisted anterior cruciate ligament (ACL) reconstruction with patellar tendon graft. METHODS From July 1986 to March 1991, 82 patients underwent arthroscopic-assisted ACL reconstruction with patellar tendon graft. Of these, 62 returned for follow-up evaluation(More)
BACKGROUND Overhead athletes are subject to adaptations in the shoulder including glenohumeral internal rotation deficit (GIRD). It has been documented that this alteration is more evident in overhead athletes with pain. Our objective was to compare glenohumeral rotation motion between symptomatic and asymptomatic handball players. MATERIALS AND METHODS(More)
PURPOSE The purpose of this study was to compare the functional results of arthroscopic treatment for traumatic anterior shoulder instability in 2 groups of athletes. METHODS Fifty patients were randomly assigned to 2 different groups with comparable patient demographics. Group A was treated with anchors loaded with absorbable sutures, and group B was(More)
PURPOSE The aim of this study was to define a safety margin for coracoid process osteotomy that does not compromise the coracoclavicular ligaments and that can be used in the coracoid transfer procedures. METHODS Thirty shoulders from 15 cadavers were dissected, exposing the coracoid process and attached anatomic structures. The distance of the insertion(More)
Scapulothoracic arthroscopy is a procedure presenting restricted indications, for resecting free bodies, benign tumors, bursitis, and snaping scapula. The authors report four cases of scapulothoracic joint arthroscopy; in the first case, only a benign tumor (osteochondroma) could be visualized; in the second case, arthroscopic resection of an osteochondroma(More)
Stress fractures are common injuries in sports medicine. Among these fractures, femoral neck stress fractures frequently have a benign course, especially when it happens in the medial aspect of the neck. This case report describes a stress fracture of the medial aspect of the femoral neck that developed a complete fracture and underwent surgical fixation.
BACKGROUND Early recognition of the clinical signs of ruptures of the pectoralis major muscle (PMM) in athletes by orthopaedic surgeons, physical therapists, and physical trainers may prove to be critical for patient access to surgical treatment while the injury is still in the acute phase. HYPOTHESIS Total ruptures of the PMM may yield a better outcome(More)
In this study, we evaluated the peak torque, functional torque ratios, and torque curve profile of the shoulder rotators in overhead athletes with impingement symptoms so as to examine possible alterations in response to sports training and shoulder pain. Twenty-one overhead athletes with impingement symptoms were compared with 25 overhead athletes and 21(More)
Shoulder instability is a common shoulder injury, and patients present with plastic deformation of the glenohumeral capsule. Gene expression analysis may be a useful tool for increasing the general understanding of capsule deformation, and reverse-transcription quantitative polymerase chain reaction (RT-qPCR) has become an effective method for such studies.(More)
A powerlifting athlete ruptured his left tendon of the pectoralis major muscle while attempting to lift 160 kg in a Brazilian bench press championship. The injury seemed to occur in the concentric phase of exercise; however, the more common mechanism of rupture is during the eccentric phase. The tendon was reinserted to the humerus 3 weeks later with screws(More)
