INTRODUCTION Mucoid degeneration of cruciate ligament is well known entity, but symptomatic lesions are rare. It is even rarer to find a symptomatic posterior cruciate ligament mucoid degeneration than anterior cruciate ligament. CASE REPORT A 65-years-old female presented to our hospital complaining of pain in right knee joint on terminal extension since 6 months. On clinical examination, th...

BACKGROUND Knee joint sagittal plane forces are a proposed mechanism of anterior cruciate ligament injury during sport movements such as sidestep cutting. Ligament force magnitudes for these movements however, remain unknown. The need to examine injury-causing events suggests elucidation via model-based investigations is possible. Using this approach, the current study determined whether sagitt...

The prevalence of sports injuries in martial arts is high. Most Taekwondo injuries also occur in the lower extremities. The aim of this study is to compare the effect of a period of plyometric exercises, with and without stretching exercises, on knee valgus dynamics, flexibility and functional variables of elite female taekwondo athletes at risk of anterior cruciate ligament injuries.  45 elite...

BACKGROUND The hamstring muscles are well positioned to limit both anterior tibial translation and anterior cruciate ligament strain during the knee flexion phase of a jump landing. We hypothesized that systematically increasing or decreasing hamstring tension during the knee flexion phase of a simulated jump landing would significantly affect peak relative strain in the anterior cruciate ligam...

Treatment of medial and lateral compartment arthritis in the anterior cruciate ligament (ACL)-deficient knee remains a topic of debate among orthopedic surgeons. This article discusses the treatment options for the ACL-deficient knee with unicompartmental arthritis and provides a rationale for clinical decision making in this difficult group of patients. Unicondylar knee arthroplasty (UKA) is a...

Objective To evaluate the effectiveness of neuromuscular training in reducing the rate of acute knee injury in adolescent female football players. Design Stratified cluster randomised controlled trial with clubs as the unit of randomisation. Setting 230 Swedish football clubs (121 in the intervention group, 109 in the control group) were followed for one season (2009, sevenmonths). Participants...

BACKGROUND Challenges in accurate, in vivo quantification of multi-planar knee kinematics and relevant timing sequence during high-risk injurious tasks pose challenges in understanding the relative contributions of joint loads in non-contact injury mechanisms. Biomechanical testing on human cadaveric tissue, if properly designed, offers a practical means to evaluate joint biomechanics and injur...

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...

BACKGROUND Recently, anatomic anterior cruciate ligament (ACL) reconstruction is emphasized to improve joint laxity and to potentially avert initiation of cartilage degeneration. There is a paucity of information on the efficacy of ACL reconstructions by currently practiced tunnel creation techniques in restoring normal joint laxity. STUDY DESIGN Controlled laboratory study. HYPOTHESIS Ante...

BACKGROUND Many individuals do not resume unrestricted, preinjury sports participation after anterior cruciate ligament reconstruction, thus a better understanding of factors associated with function is needed. The purpose of this study was to investigate the association of knee impairment and psychological variables with function in subjects with anterior cruciate ligament reconstruction. HY...
