OBJECTIVE The purpose of this study was to examine the effect of a preoperative exercise intervention on knee pain, functional ability, and quadriceps strength among patients with knee osteoarthritis before and after total knee arthroplasty (TKA) surgery. DESIGN A repeated-measures design was used to compare 2 groups over 4 data collection points. (More)
OBJECTIVE To review basic meniscal anatomy, histology, and biomechanical principles as they apply to surgery and rehabilitation. DATA SOURCES We searched MEDLINE and CINAHL for the years 1960-1999 using the terms meniscus,surgery,rehabilitation,meniscal repair, and arthroscopy. DATA SYNTHESIS Injuries to a healthy meniscus are usually produced by a(More)
This review summarises the existing knowledge about pathogenesis, differential diagnosis, conservative treatment, surgery and post-surgical rehabilitation of sports hernias. Sports hernias occur more often in men, usually during athletic activities that involve cutting, pivoting, kicking and sharp turns, such as those that occur during soccer, ice hockey or(More)
PURPOSE We systematically reviewed the evaluated efficacy of medial patellofemoral ligament (MPFL) reconstruction, rehabilitation, and patient outcomes for safely returning patients to sports. METHODS We performed a literature search using the Ovid Medline database from 1950 to present, as well as the SportDiscus and CINAHL (Cumulative Index to Nursing(More)
Preparing for the stress of total knee arthroplasty (TKA) surgery by exercise training (prehabilitation) may improve strength and function before surgery and, if effective, has the potential to contribute to postoperative recovery. Subjects with severe osteoarthritis (OA), pain intractable to medicine and scheduled for TKA were randomized into a usual care(More)
PURPOSE This retrospective study evaluated the knee flexor function of 20 patients at 25.8 +/- 5 months after anterior cruciate ligament reconstruction with use of a semitendinosus-gracilis (STG) autograft. METHODS Clinical examinations included instrumented isometric testing, conventional and prone isokinetic testing, hop testing, knee arthrometry,(More)
This investigation compared the maximum load at failure of BioScrew (Linvatec Corp, Largo, FL) and titanium alloy interference screw femoral fixation using a human cadaveric model that approximated the anatomical orientation and physiological strain rate of in vivo bone-patellar tendon-bone (BPTB) graft loading following anterior cruciate ligament(More)
BACKGROUND The biomechanical characteristics of the Meniscal Viper Repair System have not been previously studied. HYPOTHESIS Comparable meniscal lesion fixation standards will exist among the Meniscal Viper Repair System, the vertical FasT-Fix device, and vertical mattress sutures. STUDY DESIGN Controlled laboratory study. METHODS Porcine menisci (3(More)
The outcomes of 18 patients (11 females, 7 males; age, 40.4±11 years) at 2 years after ACL reconstruction with cryopreserved tibialis anterior allografts using a double bundle technique are presented. Most subjects (72%) described themselves as being moderately active before surgery. After providing written informed consent, subjects completed the 2000 IKDC(More)
Athletic women are at greater risk of anterior cruciate ligament (ACL) injury than men. Twenty, healthy, athletic women were evaluated for the effect of preferred stance limb isokinetic quadriceps femoris and hamstring fatigue from eccentric work compared with controls on the activation onset of vastus medialis, rectus femoris, vastus lateralis, the medial(More)
