PURPOSE Anterior cruciate ligament (ACL) reconstruction is commonly performed in athletes, with the goal of return to sports activities. Unfortunately, this operation may fail, and the rates of either reinjuring an ACL-reconstructed knee or sustaining an ACL rupture to the contralateral knee range from 3% to 49%. One problem that exists is a lack of(More)
In a consecutive series, we treated 41 young patients who had anterior cruciate ligament deficiency, lower limb varus angulation, and varying amounts of posterolateral ligament deficiency. Seventy-three percent of the patients (N = 30) had lost the medial meniscus and 63% (N = 26) had marked articular cartilage damage in the medial compartment. All patients(More)
BACKGROUND The purpose of this study was to prospectively evaluate the results of meniscal transplantation in a consecutive series of younger patients treated for pain in the tibiofemoral compartment following a previous meniscectomy. METHODS Forty cryopreserved menisci were implanted into thirty-eight patients. Sixteen knees also had an osteochondral(More)
OBJECTIVE To review anterior cruciate ligament (ACL) clinical studies to assess the objective functional criteria used to determine when patients can return to athletics postoperatively, and to determine the rates of reinjury to either knee when these criteria are applied. METHODS A literature search was conducted using the Medline database. The(More)
We studied a brace designed to decrease loads on the medial tibiofemoral compartment in knees with chronic pain and arthrosis to determine if pain symptoms decreased, function improved, and dynamic gait characteristics altered during walking. Eighteen patients with symptomatic medial compartment arthrosis were fitted with a commercially available brace. All(More)
Although many instruments are used to assess outcome after knee ligament reconstruction, their reliability, validity, and responsiveness have not been adequately proven. Our purpose was to assess these statistical measures in a commonly used instrument, the Cincinnati Knee Rating System. Reliability was determined from the responses of 100 subjects who(More)
PURPOSE To investigate 57 failed posterolateral procedures in 30 consecutive knees to determine factors that may have contributed to the failure. STUDY DESIGN Case series; Level of evidence, 4. METHODS Thirty patient records were reviewed by an independent surgeon. The index posterolateral operations were done for 13 acute and 17 chronic knee injuries.(More)
BACKGROUND High tibial osteotomy has been associated with significant complications, including delayed union or nonunion, loss of correction, arthrofibrosis, and patella infera. HYPOTHESES A technique for opening wedge osteotomy that incorporates an autogenous iliac crest bone graft will prevent delayed union or nonunion, allow early rehabilitation and(More)
The purpose of this study was to determine if a sports-specific training program could improve neuromuscular and performance indices in female high school basketball players. We combined components from a published anterior cruciate ligament injury prevention program for jump and strength training with other exercises and drills to improve speed, agility,(More)
BACKGROUND A prospective longitudinal investigation was conducted to determine the long-term outcome of single longitudinal meniscal repairs extending into the central avascular region in patients aged 20 years or younger. PURPOSE To determine the long-term success rate and reoperation rate of meniscal repairs extending into the avascular zone. STUDY(More)
