background:  parts of the implants placed over the meniscus during meniscal repair can wear down the cartilage in the contact zones and cause chronic synovitis. placing horizontal sutures under the meniscus may overcome this potential hazard. the purpose of this prospective study was to evaluate the midterm results of arthroscopic meniscal repair using submeniscally placed out-in horizontal sut...

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...

PURPOSE Our purpose was to determine if height, weight, and gender can be used to accurately predict proper meniscal allograft dimensions. METHODS Data were obtained from the Joint Restoration Foundation (AlloSource, Centennial, CO) regarding meniscal size and patient characteristics from meniscal donors. Donor height, weight, sex, age, and anatomic meniscal dimensions were recorded for 930 d...

Meniscectomy is recognized as an important risk factor for the development of knee osteoarthritis (OA), a disease that traditionally has been considered as a simple "wear and tear" phenomenon. However, despite numerous reports, little evidence has been presented that a limited meniscal resection, compared with a more extensive resection, reduces the risk of OA by preserving meniscal function. W...

PURPOSE To evaluate the incidence of associated injuries and meniscal tears in children and adolescents with anterior cruciate ligament (ACL) tears, we performed a retrospective review of patients, age 14 and younger, who were treated surgically at our institution. TYPE OF STUDY Retrospective review. METHODS We reviewed 39 patients (30 girls, 9 boys) with an average age of 13.6 years (range...

The first meniscal repair was described by Annandale in 1885. In addition to the patients’ reported 1-month stay in the hospital, many other changes have occurred in the techniques of meniscal repair since that time. Most repairs are performed rthroscopically, with a variety of suture techniques ranging from inside-out, outsiden, to all-inside. Regardless of the technique utilized, vertical sut...

BACKGROUND Meniscal repair offers the potential to avoid the long-term articular cartilage deterioration that has been shown to result after meniscectomy. Failure of the meniscal repair can occur several years postoperatively. Limited evidence on the long-term outcomes of meniscal repair exists. METHODS We performed a systematic review of studies reporting the outcomes of meniscal repair at a...

BACKGROUND Most biomechanical studies for evaluation of the structural properties of meniscal repairs have been performed in tensile loading scenarios perpendicular to the circumferential meniscal fibers. However, meniscal repair constructs are also exposed to shear forces parallel to the circumferential meniscal fibers during healing, particularly in the midportion of the meniscus. HYPOTHESI...

BACKGROUND Meniscal root tears cause menisci and their insertions to inadequately distribute loads and potentially leave underlying articular cartilage unprotected. Untreated meniscal root tears are becoming increasingly recognized to induce joint degradation; however, little information is known about anterior meniscal root tears and how they affect joint tissue. PURPOSE To observe the early...

BACKGROUND Meniscal root tears present in many forms and can have profound consequences on the health of knee articular cartilage. While the biomechanics, natural history, and treatment of root tears have been increasingly investigated, the spectrum of meniscal root tear patterns observed during arthroscopic examination has yet to be defined and categorized. PURPOSE To establish a classificat...
