Through a rare case of tibial tunnel encystment, we will try to elucidate the causes of this complication and its clinical and anatomical consequences. Case report: This case is about a 45-year-old patient who underwent ACL reconstruction two and a half years ago and presented with mechanical knee pain. On examination, palpation of the internal joint space was painful, and knee mobility was 6-120°. X-rays showed a bone defect with peripheral condensation along the path of the tibial tunnel, which had widened by 138.89% with an encysted appearance. Discussion and conclusion: Encystment of the tunnel after ACL reconstruction is a rare phenomenon and sparsely described in the literature (8 reported cases). Its etiology is unclear. Theories include necrosis, inflammatory reaction to a foreign body, lack of graft Osseointegration, and extravasation of joint fluid into the tunnel. MRI is the key exploration for establishing a positive diagnosis by showing tunnel widening and the formation of a unilocular or multilocular cyst. It also helps differentiate it from infection or foreign body granuloma. Encystment can pose a problem of bone substance loss in case of ACL reconstruction revision. ) [rank_math_internal_links_processed] => Array ( [0] => 1 ) [ple-content_has_sections] => Array ( [0] => ) [_eael_post_view_count] => Array ( [0] => 18 ) [trx_addons_post_views_count] => Array ( [0] => 16 ) [ekit_post_views_count] => Array ( [0] => 16 ) [trx_addons_post_likes_count] => Array ( [0] => 0 ) )
