Treatment options are limited for young, meniscal-deficient patients with pain. This patient population is not age appropriate for total joint replacement, but the loss of the meniscus leaves them at significant risk for the development of osteoarthritis. One increasingly popular option is the use of allograft meniscal transplantation. However, many questions still surround allograft meniscus transplantation. Furthermore, most reports in the literature on the results of meniscal transplantation describe small case series using clinical outcome measures and/or incomplete direct evaluation of the meniscus. Therefore, the results of meniscal allograft transplantation have been difficult to interpret and compare due to many confounding variables. In this study, we reviewed the current research of concerns on the results of meniscal allograft transplantation.

Meniscal allograft transplantation is considered to restore important functions of the meniscus after total and subtotal meniscectomy. There are patients who need meniscal allograft transplantation have concomitant lesions; chronic anterior cruciate ligament tear, chondral defect, and malalignment of the knee. Therefore proper selection of the patients and thorough preparation of operative procedure are imperative to get satisfactory results.

We report the case of a 21-year-old man with acute septic arthritis of the knee after meniscal allograft transplantation, which was successfully treated with repeated arthroscopic debridement and irrigations. Our procedures included arthroscopic debridement and irrigation with 10L normal saline, repeated arthroscopic irrigations (5 times), and intravenous antibiotics. Our decision to repeat the debridement was based on clinical and laboratory results. The significance of this case is that early aggressive arthroscopic debridement and repeated irrigations as part of a treatment protocol of acute septic arthritis after meniscal allograft transplantation can be an effective treatment option in selected cases.

The current treatment of extensive meniscal injuries has resulted in numerous investigations and clinical trials to restore normal meniscal functions. A cryopreserved meniscal allograft transplantation is one of the successful methods available to restore the meniscus. All the procedures of 26 cases were performed in an minimal open fashion, though initial four cases were done with the aid of arthroscope. In all of the grafts, we used a bone bridge which was attached to meniscus for better stability and healing. Anterior cruciate ligament reconstructions were also performed simultaneously with the meniscal procedures. We attempted to minimize articular cartilage by employing so called the "Key-hole technique" for the medial meniscus transplantation. First, the meniscal cartilage bone bridge was shaped into a cylinder and a bone tunnel was made just beside the medial border of the anterior criciate ligament insertion of the recipient knee joint, and the bone bridge of the meniscal cartilage was push to press-fit. The inserted meniscal cartilage was sutured by the usually employed technique under arthroscopic control. The lateral meniscus was shaped different to the medial meniscus in that the bone bridge was semicylindrical and the bone trough was made beside the lateral border of the anterior criciate ligament insertion of the recipient knee joint. The meniscus was put into the bone trough and the leading suture was extracted anterior to the tibia and tied the knot. The inserted meniscus was sutured in the same manner as the medial meniscus transplantation. By the above described method, the authors were able to minimize the articular cartilage invasion and transplant the meniscus with relative accuracy.

Meniscal allograft transplantation (MAT) is an accepted treatment for the symptomatic postmeniscectomized knee in younger patients. However, the likelihood of a successful outcome is reduced by various complications. One of the complications after MAT is manifested as grafted meniscal tear. However, a bucket handle meniscal tear (BHMT) following MAT is an uncommon complication and furthermore a BHMT after revisional MAT (RMAT) is a extremely rare complication. We encountered a case of BHMT after RMAT in a lateral meniscus. Retrospectively reviewing the case, we could assume the cause, which would be helpful to prevent the complication in further MAT procedures.

Purpose: We report mid to long - term results of meniscal transplantation and evaluate the important factors for successful outcomes. Materials and Methods: Between December 1999 and September 2002, 25 meniscal transplantations were performed using fresh frozen allograft. The lateral meniscus was transplanted in 19 cases and medial meniscus in 6 cases. The mean age was 34 years (range, 17~50 years) and the mean follow up was 54.8 months (range, 6~85 months). Preoperative measurements were made using a ruler graded in millimeters. Lateral meniscus was fixed by keyhole technique and medial meniscus was fixed by double bone plug technique with suturing the periphery of the meniscal transplant. All patients were evaluated with Knee Assessment Scoring System (KASS), Lysholm knee score, and Tegner activity scale for daily activity. Results: Symptoms improved in all cases. The average KASS score increased from 61.7 preoperatively to 83.8 postoperatively. The average Lysholm knee score increased from 77.7 preoperatively to 87.7 postoperatively (excellent in 3 cases, good in 17 cases, fair 4 cases, poor 1 case). But painful swellings were 3 cases, numbness in 1 case, and granuloma due to non-absorbable suture material in 1 case. Peroneal nerve palsy in 1 case was recovered after 6 weeks postoperatively. Conclusion: Meniscal allograft transplantation after subtotal or total menisectomy can significantly relieve pain and improve function of the knee joint. The exact preoperative sizing and secure fixation are essential for successful outcomes.

Recently, meniscal allograft transplantation has been regarded as a successful procedure in terms of pain relief and functional improvement for the symptomatic patients previously underwent subtotal or total meniscectomy. However, the likelihood of a successful outcome would be reduced by various complications including graft tear, shrinkage, extrusion, infection, progressive chondral injury, and granuloma due to nonabsorbable suture material. Therefore, knee surgeons need to be all aware of the complications and to make an effort to minimize them. The purpose of this article is to review the current literatures regarding clinical results and complications after meniscus allograft transplantation.

The first human meniscal allograft transplantations (MATs) were performed 30 years ago. In the early era, candidates were limited to patients who have favorable joint conditions. MAT is currently indicated for patients with post-meniscectomy symptoms, such as compartmental pain or effusion after a subtotal or total meniscectomy. The current indication for MAT is being expanded to other patients who were not indicated previously. The present article reviews how the indications of MAT have changed over the years.
