The biomechanical and clinical importance of the meniscus is now well-accepted. In accordance with this understanding, recent focus has shifted toward techniques that preserve the meniscus, including repair and meniscal allograft transplantation (MAT). Although MAT is a technically challenging procedure, evidence has suggested that it restores knee kinematics and tibiofemoral contact pressures, which may subsequently delay or prevent cartilage degeneration. Recent literature has reported concerns as to the high rate of reoperations after MAT, bringing into question the clinical utility of this procedure and its place in th...

We would like to thank Dr. Zhong1 for expressing interest and concern regarding our recently published article, “Return to Work Following High Tibial Osteotomy With Concomitant Osteochondral Allograft Transplantation.”2 His letter identifies several discussion points, and we thank the journal for the opportunity to address these concerns.

We read with great interest the article “Return to Work Following High Tibial Osteotomy With Concomitant Osteochondral Allograft Transplantation” by Agarwalla et al.1 The authors performed a retrospective analysis on 26 patients who underwent high tibial osteotomy (HTO) + concomitant osteochondral allograft (OCA) and concluded that HTO + OCA provides a high rate of return to work (RTW) for the treatment of focal chondral deficiency and varus deformity in the knee. We think this finding is of value for clinicians in decision-making.

Despite its overall good results, meniscal allograft transplantation is considered a salvage procedure, and abstention from sport practice is considered a valid solution to preserve the transplanted meniscus as long as possible. However, many patients want to return to sport, and this is often beneficial for them. Therefore, we should know how meniscal allograft transplantation performs in terms of return to sport to better counsel our patients. It is thus of primary importance to discuss general and sport-related expectations with each patient, whom should be informed of the potential short- and long-term risks of strenuo...

Surgical management of osteochondral lesions of the talus without an osteotomy depends on the size, location, and chronicity of the lesion. Bone marrow stimulation techniques, such as microfracture, can be performed arthroscopically and have consistently good outcomes in lesions less than 1  cm in diameter. For lesions not amenable to bone marrow stimulation, one-stage techniques, such as allograft cartilage extracellular matrix and allograft juvenile hyaline cartilage, may be used. Arthroscopy may be used in many cases to address these lesions; however, an arthrotomy may be required to use osteochondral autograft and...

The altered knee joint function and symptomatic state in younger patients after meniscectomy and progressive tibiofemoral arthritis remain an important unsolved treatment dilemma. Meniscal allograft transplantation has evolved as an acceptable treatment because there are few (if any) other options. The procedure is effective in most patients, who experience a decrease in tibiofemoral pain and improved knee function, even allowing a return to light recreational activities. However, biological remodeling of the implant occurs over time, with replacement of the complex circumferential and radial fibers with disorganized colla...

AbstractPurposeTo investigate degenerative morphological changes in meniscus allograft after lateral meniscus allograft transplantation (MAT) based on extrusions.MethodsNinety-one patients who underwent lateral MAT were divided into extruded and non-extruded groups. Serial magnetic resonance imaging scans obtained 6  weeks, 1 year, and at the last follow-up (midterm, 3–7 years) post-surgery were evaluated retrospectively. Degenerative morphological changes at each time point in each group were compared using the postoperative meniscal width, thickness, and intrameniscal signal intensity (IMSI) at the a...

This study aims to evaluate the role of staging arthroscopy in the diagnosis of knee chondral defects and subsequent surgical planning prior to autologous chondrocyte implantation (ACI), osteochondral allograft transplantation (OCA), and meniscus allograft transplantation (MAT). All patients who underwent staging arthroscopy prior to ACI, OCA, or MAT at our institution from 2005 to 2015 were identified. Medical records were reviewed to document the diagnosis and treatment plan based on symptoms, magnetic resonance imaging (MRI) findings and previous operative records. Operative records of the subsequent staging arthroscopy...
