“…As peças foram projetadas de forma que a área útil de coleta de fi bras forme um anel completo com 60 mm de diâmetro externo e 12 mm de espessura, a fi m de produzir um scaffold compatível com as dimensões do menisco medial humano (MICKIEWICZ et al, 2015).…”

“…Overall, magnetic resonance imaging proved only slightly more accurate than conventional radiography 167 . Mickiewicz et al 168 used X-ray microcomputed tomography to measure the size of the meniscus allograft. A further aspect of interest in the technique of meniscal allograft is the method for fixing the graft to the joint capsule and tibia.…”

Objective: the menisci are easily injured and difficult to repair. The aim of this study was to analyze the current state of meniscal surgery aimed at preserving morphology and conserving the biomechanics of the knee to prevent joint degeneration. Methodology: a search of the electronic medical literature database Medline was conducted, from http://www.ncbi.nlm.nih.gov/pubmed. The search was not limited by language. Candidate articles were identified by searching for those that included the keywords meniscus, surgery, suture, implant, allograft. The limits were included for clinical research and clinical trials. Basic research was not included. The studies selected were evaluated and classified in three different categories: basic science, reconstruction (suture and meniscectomy) and implants (scaffolds and allograft). Results: the consequences of meniscectomy performed at a young age can lead to a joint cartilage degeneration twenty years later. There are few surgical options for the repair of meniscal injuries in order both to preserve the meniscus and to ensure the long term survival of the knee joint, meniscectomy, repair, suturing the tear, or reconstruction, when a meniscal allograft or synthetic substitute is used to replace the meniscus, but the biomechanical properties of the native meniscus are not reproduced entirely by the scaffolds that exist today.Conclusion: therapies that successfully repair or replace the meniscus are therefore likely to prevent or delay osteoarthritis progression.

“…This process is to protect cell viability by preventing the formation of intracellular ice crystals. It is difficult to perform and expensive, and recent data have suggested that as little as 4%–10% of cells actually survive although the collagen net architecture does remain largely intact 24–26,29,30. Further evidence suggests that tissue, metabolic, and cell structural changes do occur after cryopreservation 31,32.…”

“…Further evidence suggests that tissue, metabolic, and cell structural changes do occur after cryopreservation 31,32. Although it does allow prolonged storage of the meniscal tissue, it offers no significant benefits over fresh frozen techniques 24,29…”

Meniscal allograft transplantation (MAT) is a possible treatment option for patients with joint pain after meniscectomy. It is necessary that the joint be aligned and stable. Current evidence shows that MAT improves pain and mechanical function in the mid to long term with patients reporting significantly improved outcomes at up to 15 years following surgery. Studies on survivorship showed up to 76% graft survival at 10 years. Recent studies have suggested a chondroprotective effect, but there is, at present, no evidence to support MAT in the prevention of osteoarthritis. This review article reported the current evidence for MAT showing support for fresh frozen, nonirradiated allografts. However, further research is required to determine the ideal indications for MAT, the optimal graft fixation method, and the safest rehabilitation protocol.
