BACKGROUND Radial transection of the peripheral fibers of the meniscus could render it nonfunctional; however, the biomechanical consequences of a complete lateral meniscal radial tear and repair in human specimens have not been elucidated. HYPOTHESIS A complete radial tear will exhibit knee contact mechanics approaching those of total meniscectomy. Repair of complete radial tears will re-cre...

Of 353 arthroscopic peripheral meniscal repairs performed using the "outside to inside" suturing technique with rasp preparation of the tear region, 74 repairs (50 medial and 24 lateral) were assessed by second-look arthroscopy and are the basis of this report. Results were graded as either healed, incompletely healed, or failed; these findings were correlated with clinical symptoms and associa...

Purpose The purpose of this study was to examine the incidence of lateral meniscal tears associated with lateral tibial plateau fractures and report the clinical outcomes of meniscal treatment with internal fixation of fractures. Materials and Methods All lateral tibial plateau fractures (Schatzker types II and III) in skeletally mature patients treated operatively at our institution between ...

Meniscal cysts are rare and often are a result of extrusion of synovial fluid through a tear of the meniscus, resulting in a one-way valve effect of the tear. Arthroscopic partial meniscectomy of the meniscus with intra-articular cyst drainage has become the standard of care. We report a case of an unusually large symptomatic medial meniscal cyst, situated postero-medially and pressing on the p...

Surgical reattachment of medial meniscus posterior root tear (MMPRT) with transtibial sutures can delay the presenceof medial knee joint compartment osteoarthritis. Most suture configurations are placed five mm away from the tornmargin in the meniscal substance which is already degenerated and may decrease the pull out strengths of repairconstruct. The number of meniscus penet...

Background: The meniscus is a semilunar fibro-cartilaginous tissue performing various function including knee joint stability, shock absorption, load distribution, joint lubrication, and joint congruity. Menisectomy often leads to articular cartilage degeneration and ends up in osteoarthritis of knee. Authors described use of mesenchymal stem cells for evaluation of healing of meniscus tear. Pu...

BACKGROUND The menisci are integral to normal knee function. The purpose of this study was to measure the contact pressures transmitted to the medial tibial plateau under physiological loads as a function of the percentage of the meniscus involved by the radial tear or repair. Our hypotheses were that (1) there is a threshold size of radial tears above which contact mechanics are adversely affe...

Meniscal radial tears are equivalent to the meniscectomized state. However, successful healing rates by current repair methods for meniscal still not satisfactory. Several suture configurations that could approximate tear gap and stabilize tissue have been developed overcome shortcomings of simple horizontal stitches cross stitches. The hybrid stitch method, composed vertical stitches, has intr...
