Nonoperative treatment and return to play after complete proximal adductor avulsion in high-performance athletes

Purpose To assess the outcome of nonoperative treatment after complete avulsion of the proximal adductor longus tendon in high-performance athletes. Methods Six consecutive athletes were included. Treatment was conservative following a strict rehabilitation plan. Following parameters were analysed: basic data, mechanism of injury, classification, tendon retraction, size of defect in MRI and return to play (RTP). Results Mean age at injury was 28 ± 5 (range 20–32) years. Overstretch (83 %) and kicking (50 %) were the most frequent injury mechanisms, and the dominant leg was involved in 83 %. Average retraction of the avulsed tendon amounted 21 ± 5 mm. Follow-up MRIs demonstrated a gradual reattachment of the tendon in all cases. All athletes returned to full sportive activity on preinjury level within 88.7 ± 12.8 (range 75–110) days with no functional deficiencies. Manual muscle strength was equal to the contralateral side. Conclusion Nonoperative treatment with a healing phase and a strict rehabilitation plan results in a functional, efficient reattachment of the tendon and allows unrestricted RTP. Since these injuries are rare, present study may help sports physicians when dealing with this type of injuries in professional athletes. Return to sports can be expected at approximately 13 weeks after injury, but can take even longer. Level of evidence Case series, Level IV.
