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 report for the first time a reconstructive procedure of the posterolateral complex using allograft tissue to restore fibular collateral ligament function. The procedure is designed for knees where insufficient soft tissues are present and suitable autogenous graft tissues are not available. Twenty consecutive patients were studied; all returned for(More)
BACKGROUND The authors have long advocated a graft reconstruction of the fibular collateral ligament, believing that direct suture repair or augmentation procedures do not provide a stable construct. PURPOSE To describe an operative technique and determine the clinical outcome of a bone-patellar tendon-bone graft anatomical replacement of the fibular(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)
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)
BACKGROUND Many authors have speculated that altered neuromuscular control and strength of the lower extremity are responsible for the gender disparity in knee ligament injury rates. HYPOTHESIS Significant increases in normalized quadriceps and hamstrings strength and limb symmetry on single-legged hop test occur with age. No gender differences in(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)
