BACKGROUND Over the long term, acute patellar dislocations can result in patellar instability, with high recurrence rates after nonoperative treatment. PURPOSE To compare the results of operative (reconstruction of the medial patellofemoral ligament [MPFL]) versus nonoperative treatment of primary patellar dislocation. STUDY DESIGN Randomized controlled(More)
Femoral and acetabular loosening can be attributed different factors, but the causes and mechanism of early failure are still obscure. The objective of this study was to investigate the relationship between gene polymorphisms and early implant failure. Fifty-eight patients older than 50 years was recruited for analysis of MMP-1 promoter polymorphisms in(More)
BACKGROUND More than 2 years after undergoing anterior cruciate ligament (ACL) reconstruction, women still present bilateral asymmetries during multijoint movement tasks. Given the well-known ACL-injury gender bias, the goal of this study was to investigate whether males also present such asymmetries more than 2 years after undergoing ACL reconstruction. (More)
With the significant increase in life expectancy for HIV-infected patients in the era of high potency antiretroviral therapy, major metabolic changes have been observed due to the prolonged period of the viral infection and the treatment itself. Osteoarticular changes resulting from these processes are mainly reported in long term HIV-infected patients(More)
OBJECTIVE The aim of this study was to compare the surgical results from reconstruction of the medial patellofemoral ligament (MPFL) with non-operative treatment of primary patellar dislocation. METHODS Thirty-nine patients (41 knees) with patellar dislocation were randomized into two groups. One group was treated conservatively (immobilization and(More)
OBJECTIVE The objective of this study was to describe the methodology of knee rotation analysis using biomechanics laboratory instruments and to present the preliminary results from a comparative study on patients who underwent anterior cruciate ligament (ACL) reconstruction using the double-bundle technique. METHODS The protocol currently used in our(More)
Malleolar fractures are rarely associated with lesions of the adjacent tendons or neurovascular structures. The association of ankle fractures with Achilles tendon rupture is even more infrequent, although both of these injuries are very common in and of themselves. To our knowledge, fracture of the lateral malleolus in association with an acute rupture of(More)
Few complications regarding the use of bioabsorbable suture anchors in the shoulder have been reported. What motivated this case report was the unusual location of the anchor, found in the acromioclavicular joint which, to our knowledge, has never been reported so far. A 53-year old male with previous rotator cuff (RC) repair using bioabsorbable suture(More)
