The results of meniscal allograft transplantation surgery: what is success?

Background: Meniscal allograft transplantation (MAT) may improve symptoms and function, and may limit premature knee degeneration in patients with symptomatic meniscal loss. The aim of this retrospective study was to examine patient outcomes after MAT and to explore the different potential definitions of 'success' and 'failure'.

Methods: Sixty patients who underwent MAT between 2008 and 2014, aged 18-50 were identified.

Patellar chondral defect treatment with a cell-free polyglycolic acid-hyaluronan-based implant and platelet-rich fibrin glue after previously failed microfracture.

Cartilage defects of the patella are difficult to treat due to the complex anatomy of the patellofemoral joint. First-line treatment of chondral patellar defects often results in failure independent of the surgical technique. Moreover, there is no recommendation for second-line treatment of failed patellar defect treatment.

Meniscal tears, repairs and replacement: their relevance to osteoarthritis of the knee.

The menisci of the knee are important load sharers and shock absorbers in the joint. Meniscal tears are common, and whenever possible meniscal tears should be surgically repaired. Meniscectomy leads to a significant increased risk of osteoarthritis, and various options now exist for replacing missing menisci, including the use of meniscal scaffolds or the replacement of the entire meniscus by meniscal allograft transplantation.

The ABC of Physical Activity for Health: a consensus statement from the British Association of Sport and Exercise Sciences.

Our understanding of the relationship between physical activity and health is constantly evolving. Therefore, the British Association of Sport and Exercise Sciences convened a panel of experts to review the literature and produce guidelines that health professionals might use. In the ABC of Physical Activity for Health, A is for All healthy adults, B is for Beginners, and C is for Conditioned individuals.

What tissue bankers should know about the use of allograft meniscus in orthopaedics.

The menisci of the knee are two crescent shaped cartilage shock absorbers sitting between the femur and the tibia, which act as load sharers and shock absorbers. Loss of a meniscus leads to a significant increase in the risk of developing arthritis in the knee. Replacement of a missing meniscus with allograft tissue can reduce symptoms and may potentially reduce the risk of future arthritis.

A biomechanical study of the meniscofemoral ligaments and their contribution to contact pressure reduction in the knee.

The aim of this study was to test the hypothesis that the meniscofemoral ligaments (MFLs) of the human knee assist the lateral meniscal function in reducing tibiofemoral contact pressure. Five human cadaveric knee joints were loaded in axial compression in extension using a 4-degree of freedom rig in a universal materials testing machine. Contact pressures pre- and post-sectioning of the MFLs were measured using pressure sensitive film.

The effects of lateral meniscal allograft transplantation techniques on tibio-femoral contact pressures.

This paper reports a series of comparative tests in vitro, that examined how meniscectomy and meniscal allografting affected tibio-femoral joint contact pressure. Knees were loaded in axial compression and pressure maps obtained from the lateral compartment using Fuji Prescale film inserted below the meniscus. This was repeated after meniscectomy, and then after meniscal allografting with fixation by a bone plug for the insertional ligaments, plus sutures.
