Abstract: Tenosynovial giant cell tumors (TGCTs) are a group of rare, benign tumors that involve the synovium,
bursae and tendon sheath and arise from the synovial tissue of the tendon sheath. Here, we reported a 21-
year-old male patient with a 4-year history of mild pain in his right knee. Magnetic resonance (MR) study
revealed a well-defined solid mass which was successfully excised by arthroscopic surgery. No recurrence
was observed after 6 months of follow up. This is a first of its kind case report of a (TGCT) arising from the
tibial attachment of the anterior cruciate ligament (ACL).Keywords: Giant cell tumors, knee, anterior cruciate ligament
