The present study describes a novel all-arthroscopic technique for medial and lateral meniscal allograft transplantation (MAT). Surgical instruments were specifically designed to assist in the allarthroscopic approach for MAT.

This planning is particularly important if the revising surgeon uses a bone plug technique for meniscal transplant, since multiple tibial tunnels will be required for fixation.Moreover, data from massive osteochondral allograft transplantation have documented a minimal rate of immunogenicity [ 27 ]. Indications, operative techniques, and preservation of meniscal allografts have been studied extensively.These findings indicate that 1 year after transplantation the meniscal allograft is nearly completely repopulated by host cells. , Meniscus Allograft Transplantation: Bone Plug Technique with ACL BPTB Allograft Reconstruction Meniscal Allograft Transplantation: Dr. David Caborn. Abstract: Allograft meniscus transplantation is indicated to restore proper knee biomechanics and prevent subsequent articular degeneration in patients with a meniscus-decient knee. A variety of techniques for xation of meniscal transplants exist, with some techniques using Meniscal allograft trans-plantation has been proposed as an alternative to meniscec-tomy. The purposes of this study were to describe an arthroscopic meniscal allograft transplantation without bone plugs technique and to report the preliminary results. Meniscal allograft transplantation involves surgically implanting a new meniscus into the knee to replace a missing meniscusMr McDermott presents a summary of the indications, surgical techniques and clinical results of meniscal allograft transplantation at Meniscal Allograft Transplantation Using Omnispan and Trans-osseous Sutures.Meniscus Allograft Transplantation: Bone Bridge Slot Technique.

Consider Meniscal allograft transplantation is a surgical procedure that involves grafting a donor meniscus into the knee of a recipient.Fresh freezing is another technique used in the preservation of the allograft however, this process kills the cells and can damage the collagen net of the graft. allograft meniscal horns have bony attachments and are fixed by bony techniques" However, Stone et al. published long-term results of meniscus transplantation with simultaneous repair of the articular cartilage and demonstrated a mean estimated procedure survival time of 9.9 years. For patients for whom meniscal preservation is not an option, meniscal allograft transplantation can be done for a select subset of patients who have become symptomatic from theirWith the advent of meniscal transplantation procedures, several techniques have evolved, including separate bone Meniscal allograft transplant (MAT) is a promising biological solution for the symptomatic young patient with a meniscus-deficient knee that has not developed advanced osteoarthritis. As surgical techniques are refined and outcomes continue to improve Traditionally, meniscal allograft transplantation has been considered an open procedure with incorporation of bone blocks from the allograft source. However, as arthroscopic techniques have advanced Many surgical methods have been described for meniscal allograft transplantation.Although bone fixation techniques are more difficult, several basic science studies have shown that they more closely replicate normal meniscus stress force protection. Meniscus transplantation techniques continue to evolve and include: free soft tissue allograft implantation separateMeniscal allograft transplantation yields fair to excellent results in almost 85 of patients.
Patients demonstrate significant decrease in pain, as well as an increase in activity. Meniscal allograft transplantation is surgery in which a meniscus -- a c-shaped cartilage in the knee -- is placed into your knee. The new meniscus is taken from a person who has died (cadaver) and donated their tissue. Lateral Meniscal Allograft Transplantation: Tapered Teardrop Technique.

Lateral meniscal allograft transplant (LMAT) has been proposed as a way to restore the lateral meniscus-deficient knee to its native form. ty - jour. T1 - Lateral Meniscus Allograft Transplantation. T2 - Arthroscopy Techniques. Abstract. Meniscal allograft transplantation techniques continue to evolve. The common goal is to reproduce the function of the meniscus. When a large meniscal loss becomes clinically relevant, meniscal allograft transplantation (MAT) is a feasible option. However, although this technique has evolved since the 80s, there are still several controversial issues related to MAT. Meniscal Allograft Transplantation in the Sheep Knee. Evaluation of Chondroprotective Effects. Bryan T. KellyEvaluation of the vascularity of the allograft meniscus was assessed using the Splteholz technique in 3 of the 4-month specimens. Meniscal allograft transplantation (MAT) offers the potential to restore partial load-bearing, decrease symptoms, and provide chondroprotective effect.Technical note. This meniscal allograft technique is used in a research protocol at the National Institute of Rehabilitation in Mexico city. Goble: An open technique especially for medial meniscal insertion is acceptable.Meniscal allograft transplantation is an important and major procedure. It should not be treated like a native meniscal resection or standard arthroscopy. 30.3). The meniscal allograft can then be shuttled through the same small medial arthrotomy (enlarged anterior portal).Finally, in conjunction with either cartilage resurfacing or osteotomy, meniscal transplantation is always completed first. Meniscal allograft transplantation (MAT) using a human donor meniscus ( allograft) was developed to treat the symptoms of joint overload followingThis review suggests that despite the quality of studies there is evidence to support the use of this technique in a very specific group of patients.
