BACKGROUND/AIM The anterior cruciate ligament (ACL) is the most frequently injured ligament of the knee, representing 50% of all knee injuries. The aim of this study was todeter mine the differences in the morphometry of knee injury patients with an intact and a ruptured anterior cruciate ligament. METHODS The study included 33 matched pairs of patients divided into two groups: the study grou...

Open-book fractures are defined as the separation of pubic symphysis or rami and disruption anterior sacroiliac, sacrotuberous, sacrospinal ligaments. They can be stabilized by fixation arch. However, indications advantages additional placement iliosacral screws remain unknown. A CT-based model healthy pelvis was created ligaments were modeled tension springs. Range motion sacroiliac joint symp...

Meniscal injury has been well documented in association with injury to the anterior cruciate ligament. The purpose of this study was to evaluate the effect of anterior cruciate ligament transection and reconstruction on meniscal strain. Four differential variable reluctance transducer strain gauges were placed in the medial and lateral menisci of nine cadaveric knees. Each specimen was mounted ...

BACKGROUND Checkrein ligament release for treatment of proximal interphalangeal joint Dupuytren contractures does not address the shortened arteries or deficient skin. The Digit Widget uses soft-tissue distraction to overcome these issues. This study compares checkrein ligament release after fasciectomy versus preliminary soft-tissue distraction, followed by operative release, for treatment of ...

OBJECTIVE To determine how normal gait patterns may change as a result of chronic anterior cruciate ligament deficiency and subsequent reconstructive surgery. DESIGN Gait testing of 10 chronic anterior cruciate ligament deficient subjects prior to and 3 months following reconstructive surgery, and 10 uninjured controls. BACKGROUND There is controversy whether persons with chronic anterior c...

OBJECTIVE To investigate the biomechanical effects of the lumbar posterior complex on the adjacent segments after posterior lumbar interbody fusion (PLIF) surgeries. METHODS A finite element model of the L1-S1 segment was modified to simulate PLIF with total laminectomy (PLIF-LAM) and PLIF with hemilaminectomy (PLIF-HEMI) procedures. The models were subjected to a 400N follower load with a 7....

OBJECTIVE To evaluate the resistance and regeneration of the patellar ligament after harvesting a graft for reconstruction of the anterior cruciate ligament, using the traditional technique of a single longitudinal skin incision or a technique of two transverse mini-incisions, in sheep. METHODS Ten sheep were used. In the right knee, we removed the graft using the traditional method, and in t...

BACKGROUND Biomechanics studies can help improve athletic performance. However, the biomechanics of knee joint ligament length changes and moment arms over six degrees of freedom (DOF) have yet to be established. OBJECTIVE To construct a knee model to investigate the length and moment arm changes of the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral lig...

OBJECTIVES To determine if regional variations in strain patterns occur within the suspensory ligament under tensile load. Local increases in strain may put certain regions of the suspensory ligament at risk and may explain the poor healing and high recurrence rates associated with suspensory branch injuries. METHODS The suspensory ligament and its bone attachments were isolated from each of ...

Cranial cruciate ligament disease (CCLD) is the most common cause of hindlimb lameness in the dog, being associated with and eventually leading to stifle osteoarthritis. Canine cranial cruciate ligament disease is a gradual degeneration of the ligament extracellular matrix (ECM) leading to ligament rupture. The aetiopathogenesis of this condition is still poorly understood but several risk fact...
