Meniscal Roots: Current Concepts Review
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...
متن کاملMeniscal root injury and spontaneous osteonecrosis of the knee: an observation.
We describe injuries to the posterior root of the medial meniscus in patients with spontaneous osteonecrosis of the medial compartment of the knee. We identified 30 consecutive patients with spontaneous osteonecrosis of the medial femoral condyle. The radiographs and MR imaging were reviewed. We found tears of the posterior root of the medial meniscus in 24 patients (80%). Of these, 15 were com...
متن کاملClinical Evaluation of the Root Tear of the Posterior Horn of the Medial Meniscus in Total Knee Arthroplasty for Osteoarthritis
PURPOSE To investigate the incidence of root tears of the posterior horn of the medial meniscus in total knee replacement arthroplasty for knee osteoarthritis and retrospectively analyze clinical results and factors associated with root tears. MATERIALS AND METHODS There were 197 knees of 140 enrolled patients who had undergone total knee replacement arthroplasty between September 2010 and Ma...
متن کاملBiomechanical Consequences of a Complete Radial Tear Adjacent to the Medial Meniscus Posterior Root Attachment Site
BACKGROUND Complete radial tears near the medial meniscus posterior root attachment site disrupt the circumferential integrity of the meniscus (similar to a posterior root avulsion). These tears can compromise the circumferential integrity, and they have been reported in biomechanical studies to be comparable with the meniscectomized state. PURPOSE To quantify the tibiofemoral contact pressur...
متن کاملPosterior horn medial meniscal root repair with cruciate ligament/medial collateral ligament combined injuries.
Many meniscal root tears remain unrepaired, potentially due to under-recognition and the technical challenge of repairing them. A great effort is made to preserve the native meniscus and restore the circumferential fibers for hoop stress resistance. It has been well demonstrated in the literature that failure to repair this will lead to increased contact pressures in the medial compartment and ...
