We retrospectively reviewed the success of meniscus repair with the FasT-Fix meniscus repair device for vertical unstable medial meniscus tears at the time of anterior cruciate ligament (ACL) reconstruction. A repair failure was defined as patients having medial knee symptoms leading to a subsequent arthroscopy confirming a tear at the repair site. Objective follow-up was obtained on 27 patients at a mean of 3.1 years postoperatively (range, 2-5 years). Two of 22 repairs (9%) in the red-red vascular zone and 4 of 5 repairs (80%) in the red-white vascular zone retore at the repair site at an average of 9 months postoperatively (range, 3-20 months). The results of this study showed a high failure rate (22%) of unstable vertical medial meniscus repairs with ACL reconstruction, especially for repairs done to tears in the red-white vascular zone.

Objectives: To compare the biomechanical strength and stiffness of the native posteromedial and posterolateral meniscotibial ligament complex (MTLC) to suture anchor repair of the MTLC.
Methods: Biomechanical testing was performed on 24 fresh-frozen pediatric human knees. Four conditions were tested: native posteromedial MTLC (n=14), native posterolateral MTLC (n=14), posteromedial MTLC repair (n=5), and posterolateral MTLC repair (n=5).

A meniscus injury is a common cartilage disease of the knee joint. Despite the availability of various methods for the treatment of meniscal injuries, the poor regenerative capacity of the meniscus often necessitates resection, leading to the accelerated progression of osteoarthritis. Advances in tissue engineering have introduced meniscal tissue engineering as a potential treatment option.

Inside-out repair of meniscal tears is the gold standard surgical approach; however, its use is limited by the need for a posterior incision and neurovascular risk. In this Technical Report, we present details of the all-inside arthroscopic tie-grip approach for repairing a radial tear of the midbody of the lateral meniscus using an all-inside device (TRUESPAN) and a slotted cannula. In contrast to the inside-out approach, this technique helps reduce surgical invasiveness and provides stable fixation as the vertical mattress sutures bundle the circumferential fibers and act as rip stops for the horizontal sutures.

Background: Meniscus tears can change the biomechanical environment of the knee joint and might accelerate the development of osteoarthritis. The aim of this study was to investigate the dynamic biomechanical effects of different medial meniscus tear positions and tear gaps on the knee during walking.
Methods: Seven finite element models of the knee joint were constructed, including the intact medial meniscus (IMM), radial stable tears in the anterior, middle, and posterior one-third regions of the medial meniscus (RSTA, RSTM, RSTP), and the corresponding unstable tears (RUTA, RUTM, RUTP).
