PURPOSE To identify the structural integrity of the healing site after arthroscopic repair of a posterior root tear of the medial meniscus by second-look arthroscopy and to determine the clinical relevance of the findings. MATERIALS AND METHODS From January 2005 to December 2010, 20 consecutive patients underwent arthroscopic modified pull-out suture repair for a posterior root tear of the me...

Meniscal root tears are defined as radial tears located within 1 cm from the meniscal attachment or a bony rootavulsion. This injury is biomechanically comparable to a total meniscectomy, leading to compromised hoop stressesresulting in decreased tibiofemoral contact area and increased contact pressures in the involved compartment.These changes are detrimental to the articular cartilage and ult...

OBJECTIVE To evaluate whether an alteration of the lower limb axis is associated with meniscal extrusion. MATERIALS AND METHODS Ninety-four patients who had complained of knee pain with good knee function and had a knee magnetic resonance image (MRI) and a full-length X-ray taken of the lower limb were included in the study. Meniscal extrusion was measured in the coronal MRI. Subluxation of t...

BACKGROUND Most knee joint biomechanics studies have involved knees with an isolated anterior cruciate ligament (ACL) injury. However, a large portion of patients with injured ACLs have accompanied meniscus tearing. In this study, the in vivo alteration of knee biomechanics after tearing the ACL with or without combined medial or lateral meniscus tear was investigated during stair-ascending act...

Case Report A sixteen-year-old white girl had a history of pain in the right knee for four months, especially in the medial joint line, and occasional episodes of giving-way during sports activities. She could recall no trauma to the knee. Examination of the knee was unremarkable except for slight tenderness over the medial joint line. There was no effusion, and the McMurray and Lachman tests w...

BACKGROUND Tears of the posterior root of the medial meniscus are becoming increasingly recognized. They can cause rapidly progressive arthritis, yet their biomechanical effects are not understood. The goal of this study was to determine the effects of posterior root tears of the medial meniscus and their repairs on tibiofemoral joint contact pressure and kinematics. METHODS Nine fresh-frozen...

Knowledge regarding changes of proteoglycans (acid mucins) in human osteoarthritis (OA) meniscus may help understanding development meniscal degeneration. Therefore, present study was planned to know acid mucins knee OA menisci by histochemical analysis different parts medial and lateral both legs. Medial were collected from 110 joints sexes. Normal tissue sheep taken as control studied for his...
