Surgical versus conservative management of traumatic proximal adductor longus avulsion injuries: A systematic review

Proximal avulsion injuries of the adductor longus have been managed both conservatively and operatively with good clinical outcomes, but there is no consensus on which option yields the best results. Thus, the present study aimed to review the available literature, comparing the outcomes and the time to return to sports with different management options.

This study was conducted according to the PRISMA statement. The literature search was conducted in September 2020. All the clinical trials investigating the management of traumatic proximal adductor longus avulsion injuries were considered for inclusion. Only studies reporting data from athletes were considered. The outcomes of interest were the time to return to sport and return to preinjury activity level.

Data from 46 patients were retrieved. The mean follow-up was 24.6 ± 23.8 months. The study population was represented by male athletes with a mean age of 30.0 ± 4.8. Mean stump retraction was 3.3 ± 0.6 cm in the surgical and 1.7 ± 0.6 in the conservative cohort (P = 0.07). The rate of patients returning to prior activity level was similar in the two groups, but surgically treated patients required a longer time to return to sport (3.9 ± 1.5 months vs. 2.2 ± 1.0 months, P = 0.0001).

Conservative management for traumatic avulsion of the proximal adductor longus insertion may produce shorter time to return to sport. Both conservative and operative strategies allowed to achieve similar pre-injury activity level.
