Purpose: Surgical management of meniscal tears has undergone several developments in the past few decades, expanding from meniscectomy to novel treatment via repair, transplantation, and collagen implantation. Meniscal scaffolds are a novel treatment option that aim to provide a scaffold for the ingrowth of new meniscal tissue after partial meniscectomy. The implant is made from type I collagen fibers harvested from bovine Achilles tendon. The implant is designed for degradation after tissue reconstitution. This video presents a technique for implantation of this scaffold with subsequent osteochondral allografting. Methods: The video presents the case study of a 39-year-old man who has experienced progressive medial knee pain for several years. Physical examination findings and imaging studies revealed a medial meniscus tear and an osteochondral defect in the weight-bearing portion of the medial femoral condyle. The video reviews the patient's case information, imaging studies, and indications for surgery. The video then details the technique for simultaneous osteochondral allografting and meniscal scaffold implantation. Results: After the procedure, the video reviews the postoperative treatment for the patient. In addition, literature on the outcomes of meniscal collagen implantation is reviewed. Conclusion: Osteochondral lesions and complex, irreparable meniscus tears can be simultaneously managed with the use of an implantable meniscal scaffold and osteochondral allografting. Meniscal scaffolding is a promising technique for the management of meniscal tears.
