Background: In most cases, the results of arthroscopic fixation for the treatment of avulsed tibial spine in kids and teens are usually satisfactory. Arthroscopic fixation has greater results in younger patients. This study aimed to evaluate the clinical as well as radiological outcomes of avulsed tibial spine management by arthroscopic fixation.

Subject & Methods: This is a prospective study carried out on 18 cases, presented with fractures of the tibial intercondylar eminence, and managed by arthroscopic fixation at Zagazig University Hospitals. The follow-up duration was 6 months. Clinical as well as radiological assessments were applied pre- and post-operative.

Results: Regarding classification according to Mayers and Mckeever 10 cases (55.5%) were type II and 8 cases (44.5%) were type III. According to the lysholm score, 15 cases (83.3%) had excellent outcomes and 3 cases (16.6%) had good outcomes, all cases were negative Lachman postoperatively, and no symptoms of instability. Postoperative complications include effusion which subsided within one month in two patients, superficial wound infection in another one which subsided after usage of appropriate antibiotic, and one patient had lost the last 5o of terminal extension.

Conclusion: Arthroscopic management of avulsed tibial spine injuries has many advantages, including complete joint evaluation, treatment of related injuries, early mobilization, rapid rehabilitation, and a shorter length of stay in the hospital
