Purpose: Describe the evolution of the reconstruction of meniscal rim with semitendinosus tendon in a patient\r\nwith knee pain after a subtotal meniscectomy and absence of meniscal wall.\r\nMethod: 32 years old male with a six-month history of the left knee pain after a subtotal meniscectomy. The MRI\r\nindicated a small internal meniscal remainder without posterior horn attachment. Taking this absence as a relative\r\ncontraindication for implant and meniscal transplantation, the reconstruction of a new meniscal wall with semitendinosus\r\ntendon autograft was considered. A collagen meniscal implant was attached to the new wall five months later.\r\nResults: After two years the patient referred only non specific discomfort with full pain relief in the medial compartment.\r\nThe MRI revealed integration of implants without significant degenerative changes compared to previous images.\r\nConclusions: This staged technique was designed to restore medial meniscus-like biologic tissue in a symptomatic\r\npatient following arthroscopic subtotal meniscectomy with a significant loss of the peripheral meniscus rim. Symptomatic\r\nimprovement was obtained at two years follow-up.
