Background: Ankle sprains are amongst the most common sports injuries. Our study aimed to evaluate the results of arthroscopic surgery of detachable osteochondritis lesions in the talus (OLT) following rotational trauma in military patients referred to us.
Methods:  We assessed 120 patients referred to our Hospital from June 2021 to June 2021 due to detached osteochondritis lesions in the talus of the foot. The lesion was due to rotational trauma and ankle sprain. Time to return to activity, ATFL rupture, PTFL rupture, OS trigonum, rupture of the lower desperation CFL, Loose body, and location were compared.
Results: Out of 120 patients, 107 (89.2%) were male. The mean age of the patients was 38.17±12.70 years. The mean time to return to activity was 108.07±27.87 days in women and 92.89±25.56 days in men (P = 0.066). ATFL rupture was 11 (84.6%) in women and 48 (44.9%) (P = 0.007). Lower syndesmosis was 8 (61.5%) in women and 30 (28.0%) (P = 0.014). The mean time to return to activity in patients <45 years was 87.54±23.59, and in patients >45 years was 114.51±22.81 days (P = 0.0001). There was no significant difference in the distribution of ATFL rupture, PTFL rupture.
Conclusion: The results of this study showed that the mean time to return to activity in female patients was longer than in males. Also, the return time to activity in patients less than 45 years was less than in patients over 45 years. The rupture of ATFL, and inferior Syndesmosis was higher in female than male patients.
