The osteochondral autograft transfer system (OATS) procedure is at the forefront of cartilage restoration surgeries of the knee, offering superior return to sport rates and long-term functionality. This technique reports an arthroscopic OATS procedure of the lateral femoral condyle with donor-site backfill using an osteochondral allograft plug. Potential complications from unfilled donor site sockets are eliminated through donor site backfill with an allograft plug.

Managing rerupture of the triceps brachii tendon after surgical repair is challenging due to poor tissue quality, retraction, and adhesions. This clinical scenario often requires augmentation with native tissue or tendon allografts. Traditional techniques include V-Y advancement, reinforced triceps advancement with double row or suture bridge fixation, and allograft tendon augmentation.

We present an elite footballer in his 20s with a large and symptomatic osteochondral lesion of the weight-bearing area of the medial femoral condyle, who was proposed for a single plug fresh osteochondral allograft transplantation. The lesion was due to repetitive micro traumas and had become highly symptomatic being responsible for making the football practice at a professional level almost impossible, reaching a point that keeping an elite sports career was compromised. Six months after surgery, the athlete returned to sports and, at a 3-year follow-up, still participated in elite high-level football, with a Tegner Activity Scale 10/10, IKDC 93.

Background: Chondrocyte viability is associated with the clinical success of osteochondral allograft (OCA) transplantation.
Purpose: To investigate the effect of distal femoral OCA plug harvest and recipient site preparation on regional cell viability using traditional handheld saline irrigation versus saline submersion.
Study Design: Controlled laboratory study.

Based on recent evidence-based advances in meniscus allograft transplantation (MAT), fresh (viable) meniscus allografts have potential for mitigating key risk factors associated with MAT failure, and preclinical and clinical data have verified the safety of fresh meniscus allografts as well as possible efficacy advantages compared with fresh-frozen meniscus allografts. The objective of this study was to prospectively assess clinical outcomes for the initial cohort of patients undergoing MAT using fresh meniscus allografts at our center. Patients who were prospectively enrolled in a dedicated registry were included for analyses when they had undergone primary MAT using a fresh meniscus allograft for treatment of medial and/or lateral meniscus deficiency with at least 1-year follow-up data recorded.
