BACKGROUND: Association of tendon degeneration, pre-existing posterior heel pain, Haglund's bump, retrocalcaneal spur, and mode of injury varies for the insertional and non-insertional type of tendoachilles tears (TA). PURPOSE: The study compares the various predisposing factors that determine the distinct type of TA tear and the outcome following a repair. METHODS: This is a retrospective study of the patients who underwent tendoachilles repair during January 2012-June 2018. Patients above 18 years with a minimum follow-up of two years were included. Patients with calcaneal tuberosity avulsions, prior surgeries, and open injuries were excluded. Patients were divided into groups 1 (insertional tears (IT)) and 2 (non-insertional tears (NIT)), and further subdivided based on the tendon degeneration (as D-degenerative and N-normal sub types) from ultrasound findings. AOFAS score and predisposing factors like degeneration, posterior heel pain, Haglund's bump, spur, and mechanism of injury were compared between the groups. RESULTS: The study included N = 146 with a mean age of 51.6 years and mean follow-up of 38.6 (range 24 to 96) months. IT associated with degeneration (IT-D) had a trivial fall as the predominant mechanism (P
