[Purpose] The purpose of this study was to provide useful information for future treatments and to organize rehabilitation programs for anterior cruciate ligament injury by assessing isokinetic muscle strength and laxity of knee joints in athletes with anterior cruciate ligament injuries. [Subjects and Methods] Thirty-one high school athletes with anterior cruciate ligament injuries participate...

background: despite the importance of hamstring tendon autograft, one major disadvantage in applying this technique in the surgical reconstruction of anterior cruciate ligament is individual variability in the tendon diameter. hence, the purpose of the present study was to use anthropometric parameters such as gender, height and body mass index to predict 4-strand (quadruple) hamstring tendons ...

conclusions clonidine plus bupivacaine can increase the duration of motor and sensory block in arthroscopic cruciate ligament repair under spinal anesthesia. however, due to significant hemodynamic changes, further studies are required to determine a safer dose. results all patients were males with a mean age of 24.9 years in group b, and 25.2 years in group bc (p > 0.05). in group bc, time lap...

The significance of the posterior cruciate ligament in the stability of the knee was investigated in dogs and it was compared with that of the anterior cruciate ligament by studying the changes produced in the knee after transection of either ligament. Osteophyte formation and changes in articular cartilage were less prominent after division of the posterior cruciate ligament. A complete longit...

Posterolateral instability (PLI) is common with posterior cruciate ligament tears and is less common with anterior cruciate ligament tears, and isolated PLI is rare. There are varying degrees of PLI with respect to pathologic external tibial rotation, and varus laxity. Surgical treatment of PLI must address all components of the PLI (popliteus tendon, popliteofibular ligament, lateral collatera...

BACKGROUND The role of knee bracing in anterior cruciate ligament reconstructions is controversial. HYPOTHESIS Functional bracing will have an effect on subsequent knee injury in skiers with anterior cruciate ligament reconstruction. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS From 1991 to 1997, 11606 skiers at a major destination ski resort underwent preseason knee screening...

BACKGROUND There is controversy regarding the necessity of reconstructing both the posterolateral and anteromedial bundles of the anterior cruciate ligament. HYPOTHESIS A laterally oriented transtibial drilled femoral tunnel replaces portions of the femoral footprints of the anteromedial and posterolateral bundles of the anterior cruciate ligament. STUDY DESIGN Descriptive laboratory study....

normal 0 false false false en-us x-none ar-sa background: elective knee surgery for repairing anterior cruciate ligament is usually associated with moderate to severe postoperative pain, and, therefore, selecting appropriate analgesia can considerably facilitate pain control and patient’s discharge.this study was designed to compare the analgesic effectiveness of administration of ropivacaine o...

PURPOSE The purpose of the study was to compare frequency of meniscal repair to partial meniscectomy in patients undergoing anterior cruciate ligament reconstruction using the American Board of Orthopaedic Surgeons (ABOS) database. HYPOTHESES (1) Practice patterns are similar with respect to geographic region. (2) Surgeons with fellowship training perform more meniscal repairs compared with g...

BACKGROUND The effectiveness of anterior cruciate ligament reconstruction for restoring normal knee kinematics is largely unknown, particularly during sports movements generating large, rapidly applied forces. HYPOTHESIS Under dynamic in vivo loading, significant differences in 3-dimensional kinematics exist between anterior cruciate ligament-reconstructed knees and the contralateral, uninjur...
