Seventy-two patients with subacute or chronic rupture of the anterior cruciate ligament were randomly assigned to autograft reconstruction with four-strand gracilis and semitendinosus tendon (N = 37) or with patellar tendon-bone (N = 35) from the ipsilateral side. The groups were similar in terms of age, sex, level of activity, degree of laxity, meniscal lesions found surgically, and rehabilitation program. The follow-up was performed at another hospital by independent observers after 6, 12, and 24 months. Sixty-one patients (32 with hamstring tendon grafts and 29 with patellar tendon grafts) complied with the follow-up routine for the full 24 months. No differences were found between the groups with respect to Cincinnati functional score, KT-1000 arthrometer measurements, or stairs hopple test results. The subjective result and the single-legged hop test result were better for the hamstring tendon group after 6 and 12 months, but no differences were found after 24 months. The hamst...

Strength of graft fixation is the weakest link in anterior cruciate ligament reconstruction. There is no difference in initial fixation strength between different hamstring tendon graft femoral fixation devices. Randomized experimental study. Each of six devices was used in the fixation of 10 quadrupled human semitendinosus-gracilis tendon grafts in tunnels drilled in porcine femora and tested 10 times with a single-cycle load-to-failure test at a rate of 50 mm/min and 10 times with a 1500-cycle loading test between 50 and 200 N at one cycle every 2 seconds. The specimens that survived the cyclic loading were subjected to a single-cycle load-to-failure test. The Bone Mulch Screw (1112 N) was strongest in the single-cycle load-to-failure test, followed by EndoButton CL (1086 N), RigidFix (868 N), SmartScrew ACL (794 N), BioScrew (589 N), and RCI screw (546 N). It also showed the lowest residual displacement (2.2 mm) and was strongest in the single-cycle load-to-failure test after cyc...

There is a lack of consensus regarding the best option for the treatment of acute Achilles tendon rupture. Treatment can be broadly classified as operative (open or percutaneous) or nonoperative (casting or functional bracing). Postoperative splinting can be performed with a rigid cast (proximal or distal to the knee) or a more mobile functional brace. The aim of this meta-analysis was to identify and summarize the evidence from randomized, controlled trials on the effectiveness of different interventions for the treatment of acute Achilles tendon ruptures. We searched multiple databases (including EMBASE, CINAHL, and MEDLINE) as well as reference lists of articles and contacted authors. Keywords included Achilles tendon, rupture, and tendon injuries. Three reviewers extracted data and independently assessed trial quality with use of a ten-item scale. Twelve trials involving 800 patients were included. There was a variable level of methodological rigor and reporting of outcomes. Open operative treatment was associated with a lower risk of rerupture compared with nonoperative treatment (relative risk, 0.27; 95% confidence interval, 0.11 to 0.64). However, it was associated with a higher risk of other complications, including infection, adhesions, and disturbed skin sensibility (relative risk, 10.60; 95% confidence interval, 4.82 to 23.28). Percutaneous repair was associated with a lower complication rate compared with open operative repair (relative risk, 2.84; 95% confidence interval, 1.06 to 7.62). Patients who had been managed with a functional brace postoperatively (allowing for early mobilization) had a lower complication rate compared with those who had been managed with a cast (relative risk, 1.88; 95% confidence interval, 1.27 to 2.76). Because of the small number of patients involved, no definitive conclusions could be made regarding different nonoperative treatment regimens. Open operative treatment of acute Achilles tendon ruptures significantly reduces the risk of rerupture compared with nonoperative treatment, but operative treatment is associated with a significantly higher risk of other complications. Operative risks may be reduced by performing surgery percutaneously. Postoperative splinting with use of a functional brace reduces the overall complication rate. Therapeutic Level I.

Anterior cruciate ligament injury rates are reported to be two to eight times higher in women than in men within the same sport. Because the menstrual cycle with its monthly hormonal fluctuations is one of the most basic differences between men and women, we investigated the association between the distribution of confirmed anterior cruciate ligament tears and menstrual cycle phase. Sixty-nine female athletes who sustained an acute anterior cruciate ligament injury were studied within 24 hours of injury at four centers. The mechanism of injury, menstrual cycle details, use of oral contraceptives, and history of previous injury were recorded. Urine samples were collected to validate menstrual cycle phase by measurement of estrogen, progesterone, and luteinizing hormone metabolites and creatinine levels at the time of the anterior cruciate ligament tear. Results from the hormone assays indicate that the women had a significantly greater than expected percentage of anterior cruciate li...

Purpose: Lesions of the ligamentum teres have only occasionally been reported in the literature. However, with arthroscopy, pathology of the ligamentum teres has been increasingly recognized. The purpose of this article is to report the clinical characteristics associated with rupture of the ligamentum teres and the results of arthroscopic treatment. Type of Study: Case series study. Methods: All patients undergoing hip arthroscopy have been prospectively assessed using a modified Harris Hip score (100 point maximum) obtained preoperatively and postoperatively at 3, 12, 24, and 60 months. In this study, 271 cases had at least 1 year of follow-up evaluation. From this population, 41 patients were identified with lesions of the ligamentum teres. Twenty-three of these were traumatic in origin and represent the substance of this study. The remainder (18) were hypertrophic or degenerative. Results: We noted 100% follow-up at an average of 29.2 months. Patients included 14 women and 9 men...
