Optimised return to play: high treatment success rate in core muscle injury with surgical release of the anterior tendon of the rectus abdominis muscle and proximal tenotomy of the adductor longus muscle.

OBJECTIVES: Core muscle injury is a debilitating condition that causes chronic groin pain in athletes, particularly common in soccer players. The condition is characterised by pain in the inguinal region and can lead to a significant number of absences from high-intensity physical activity. It is caused by repetitive overload without proper counterbalance from the abdominal muscles, hip flexors, and adductors in susceptible athletes. Surgical indications for core muscle injury consider cases where non-surgical treatments have not provided sufficient relief. The aim of this study was to assess the results of surgical intervention for core muscle injury using the technique employed by the Sports Medicine Group of (NAME WITHHELD). The procedure involves releasing the anterior portion of the tendon of the rectus abdominis muscle near the pubic symphysis, along with proximal tenotomy of the adductor longus muscle tendon.

METHODS: This study utilised a consecutive historical cohort analysis of the medical records of 45 male athletes, of which, 75.6% were professional soccer players, who underwent surgical treatment between January 1, 2002, and December 31, 2021. The participants included active athletes aged between 18 and 40 years, with a mean age of 23.9 years, and were diagnosed with myotendinous core muscle injury. These athletes experienced pain in the pubic symphysis and adductor tendon region and had previously undergone medical treatment and physical therapy for a duration of three to six months without significant improvement.

RESULTS: The average time for athletes to return to sport after surgery was 135 days, with a majority of participants being soccer and futsal players. The surgical intervention yielded promising results, with a positive correlation between unilateral injuries and the time taken to return to sport. The complication rate was low, at 6.7%. Notably, the rate of symptom resolution was high, at 93.3%. Furthermore, the analysis indicated that the player's position on the field significantly influenced the discharge period, suggesting that the game position plays a role in the recovery process.

CONCLUSION: The combined surgical procedure involving the release of the rectus abdominis tendon and adductor longus muscle tenotomy demonstrates favourable outcomes for athletes with core muscle injury. This study provides strong support for the effectiveness of this surgical approach in managing the condition and offers a potential path to recovery and return to sports activities.

STUDY DESIGN: Cross-sectional study.
