Posterior root medial meniscus reconstruction: an option in chronic posterior root meniscal injury management.

Posterior root medial meniscus (PRMM) tears have shown to be biomechanically equivalent to complete meniscectomy. Drawbacks from PRMM tears repair are unsatisfactory healing rates. In this case report, we outlined a PRMM reconstruction with gracilis graft healing outcome in chronic PRMM tear case, based on clinical and MRI evaluation. A 60-year-old man reported a chief complaint of increasing pain on the right knee joint in the last 1 year after a deep-flexion injury. On MRI investigation, we confirmed the chronic PRMM tear as Osteoarthritis Kellgren-Lawrence grade II. Then, we planned to perform a PRMM reconstruction with gracilis graft per arthroscopy. At the 6-month MRI evaluation, we found healing of the attached PRMM on its footprints, with intact graft transition from the meniscus to the tibial bone tunnel.
