“…Oh et al 101 found that second-look arthroscopy was performed after MAT in 100% of cases in 2 studies and about 46% of cases in 12 studies; the rate was not reported in 1 study. The authors were unable to find distinct indications for performing second-look arthroscopy, however most studies performed second-look arthroscopy for objective evaluation or to treat another knee problem.…”

Background: A large number of systematic reviews and meta-analyses regarding the meniscus have been published. Purpose: To provide a qualitative summary of the published systematic reviews and meta-analyses regarding the meniscus. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic search of all meta-analyses and systematic reviews regarding the meniscus and published between July 2009 and July 2019 was performed with PubMed, CINAHL, EMBASE, and the Cochrane database. Published abstracts, narrative reviews, articles not written in English, commentaries, study protocols, and topics that were not focused on the meniscus were excluded. The most pertinent results were extracted and summarized from each study. Results: A total of 332 articles were found, of which 142 were included. Included articles were summarized and divided into 16 topics: epidemiology, diagnosis, histology, biomechanics, comorbid pathology, animal models, arthroscopic partial meniscectomy (APM), meniscal repair, meniscal root repairs, meniscal allograft transplantation (MAT), meniscal implants and scaffolds, mesenchymal stem cells and growth factors, postoperative rehabilitation, postoperative imaging assessment, patient-reported outcome measures, and cost-effectiveness. The majority of articles focused on APM (20%), MAT (18%), and meniscal repair (17%). Conclusion: This summary of systematic reviews and meta-analyses delivers surgeons a single source of the current evidence regarding the meniscus.

“…Since the midbody and parts of the anterior and posterior horns of meniscal allografts are fixed to the remaining rim of the native meniscus/joint capsule, a vascularized meniscocapsular junction can be observed in well-healed meniscal allografts during second-look arthroscopy. 26 A circumferentially oriented disruption of the meniscocapsular junction and early meniscocapsular fixation failure were defined as meniscocapsular separation tears.…”

Association Between Meniscal Allograft Tears and Early Surgical Meniscal Allograft Failure

et al. 2021

Background: Meniscal allograft transplantation (MAT) has become a viable treatment option for patients with symptomatic meniscal deficiency. Some patients experience early surgical meniscal allograft failure attributed to causes that have not yet been sufficiently clarified. Purpose: To evaluate the prevalence, types, and distribution of arthroscopically confirmed meniscal allograft tears and the associated effect on surgical meniscal allograft survival. Study Design: Cohort study; Level of evidence, 3. Methods: Patients undergoing MAT with a minimum 2-year follow-up were retrospectively reviewed. Descriptive and surgical data were collected. Type and location of arthroscopically confirmed meniscal allograft tears were recorded and compared between medial and lateral allografts and suture-only and bone block fixation. A survival analysis was conducted to evaluate the effect of meniscal allograft tears on surgical meniscal allograft survival. Results: This study included 142 patients (54% male; mean ± SD age, 29.6 ± 10.4 years) with a mean follow-up of 10.3 ± 7.5 years. The prevalence of meniscal allograft tears was 32%, observed at a median of 1.2 years (interquartile range, 2.8 years) after MAT. The posterior horns were most frequently affected, followed by the posterior roots, midbodies, anterior horns, and anterior roots. The most frequently observed tear types were root tears (43%), followed by longitudinal, horizontal, radial, complex, bucket-handle, and meniscocapsular separation tears. A statistically significant association was found between meniscal allograft tear types and fixation techniques ( P = .027), with root tears predominant after suture-only as compared with bone block fixation (57% vs 22%). Patients with meniscal allograft root tears were a mean of 5.4 years (95% CI, 1.6-9.2 years; P = .007) younger than were patients without root tears. The 1-year surgical meniscal allograft survival rate was significantly lower for torn versus intact meniscal allografts (75% vs 99%; P < .001). Conclusion: Meniscal allograft root tears were predominant, associated with younger patient age, and more often observed when using the suture-only fixation technique versus the bone block fixation technique. Torn meniscal allografts were associated with early surgical graft failure when compared with intact meniscal allografts, resulting in a significantly lower 1-year survival rate.

“…Beyond the patient's native anatomy, surgeons must consider the advantages and disadvantages inherent to the procedure ( Table 2 ). In the short to intermediate term, MAT has been shown to improve pain according to Lysholm and IKDC subjective scales 12 , 14 , 15 and regain lost function. 8 Long-term, it may be chondroprotective based on biomechanical evidence, 15 which ultimately may delay arthroplasty.…”

Over recent years, appreciation for the critical role of the meniscus in joint biomechanics has led to an emphasis on meniscal preservation. 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, it is vital to consider the utility of such procedures and offer a straightforward approach to MAT. This article and accompanying video provide a step-by-step tutorial on how to perform a MAT using the bridge and slot technique, its key pearls and pitfalls as well as the relevant advantages and disadvantages of MAT.
