PURPOSE To identify and describe reliable landmarks for tibial tunnel placement in anatomical ACL reconstruction. METHODS Eight non-paired cadaveric knees were used. After dissection, the tibial plateaus, menisci and ACL insertions were grossly observed to identify anatomical landmarks and relate them to the ACL insertion site. The specimens were scanned(More)
This study compared hip rotation range of motion in judo athletes with and without a history of low back pain. Forty-two athletes (22 males) were divided into two groups: 21 with history of low back pain (HLBP) and 21 without history of low back pain (Control). Internal and external hip rotation range of motion in active and passive movement were measured(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)
CONTEXT AND OBJECTIVE Patellar tendinopathy is a common condition in sports. It may occur at any location of the patellar tendon, but the most commonly affected area is the inferior pole of the patella. Among various diagnostic tests, the one most used is palpation of the inferior pole of the patella. The aim of this study was to investigate the prevalence(More)
The importance of knee position for bodily stability is described by some authors, however Biodex Stability System (BSS) trials have not been used to assess the reliability and effects of different knee positions. The purposes of this study were to test the reliability of BSS indices using two knee positions in the measurement protocol (either permitting(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)
Rotator cuff tear is one of the most common causes of shoulder dysfunction. Gene expression analysis may be a useful tool for understanding tendon tears and the failure of cuff healing, and reverse-transcription quantitative polymerase chain reaction (RT-qPCR) has become an effective method for such studies. However, this technique requires the use of(More)
OBJECTIVE The aim of this study was to evaluate the procedures used by knee surgeons in Brazil for treating and rehabilitating anterior cruciate ligament injuries. METHODS A questionnaire consisting of 21 closed questions was developed, addressing topics relating to treatment and rehabilitation after anterior cruciate ligament reconstruction. The(More)
OBJECTIVE to evaluate the return to sport after surgical treatment for pubalgia among 30 professional soccer players and describe the surgical technique used. METHOD this case series was evaluated by means of a questionnaire and physical examination on 30 male professional soccer players of mean age 24.4 years (range: 18-30). The mean duration of the(More)
BACKGROUND The anterior cruciate ligament (ACL) is an important structure in the knee. The ACL does not heal following lesions, and surgical reconstruction is the standard treatment among athletes. Some steps of ACL reconstruction remain controversial. It is important to fully understand the anatomy of the ACL to accurately reproduce its anatomy during(More)
