Abstract
Tibial spine avulsion fractures (TSAFs) are an uncommon cause of knee pain in children and adolescents and are exceedingly rare in adults. In skeletally mature individuals, these injuries typically result from high-energy trauma, such as motor vehicle accidents, and are often associated with concomitant knee injuries. We present the case of an adult female who sustained a TSAF after a fall while skateboarding. Given the nature of the injury, the risks and benefits of nonoperative versus operative management were discussed, and the patient elected to undergo surgery. Arthroscopic fixation of the tibial spine via the suture pull technique, along with a concomitant repair of the posterior horn of the medial meniscus, was performed and yielded satisfactory results at the final follow-up visit. This case highlights an uncommon injury in adults while demonstrating the effectiveness of the arthroscopic suture pull fixation in achieving favorable clinical outcomes.
