Multiligamentous knee injuries involve at least two ligaments and usually result from high-energy trauma, causing significant functional limitations.\n\nOne specific injury is the \"Stener-like\" lesion of the medial collateral ligament (MCL), characterized by an avulsion at its distal tibial insertion with interposition of tendons from the pes anserinus, which prevents natural healing. This lesion often occurs with other ligament or bone injuries and requires surgical treatment.\n\nDiagnosis is clinical, supported by MRI to confirm the distal lesion and tendon interposition. Despite its importance, literature on this injury is scarce, with only a few studies and case reports, often limited by small sample sizes and lack of standardized follow-up assessments.\n\nDue to the rarity and complexity of these injuries, there is a need for a comprehensive clinical study with standardized evaluations to improve understanding and develop standardized surgical treatments for isolated and associated Stener-like MCL lesions.",[50,51],"Ligament Injury","Knee Injuries","2025-09-15",{"date":54,"type":55},"2025-09-16","ACTUAL",{"date":57,"type":55},"2025-09-10",{"date":59,"type":46},"2030-08",{"name":32,"class":6},1]
