Adductor Injuries in Athletes:

Understanding, Diagnosing and Treating a Common Sports Problem 

Justin W. Arner M.D., AANA Communications and Technology Committee and Alexander Markes, M.D. 

Adductor injuries are among the most frequent and impactful musculoskeletal problems encountered in competitive sports. They pose a particular challenge in sports that demand rapid direction changes, high-speed acceleration and powerful kicking or skating motions such as soccer, hockey and basketball. These injuries account for nearly half of all acute hip problems in soccer and about one-quarter of injuries in professional basketball, underscoring their significance in athletic populations. As research evolves, clinicians now better understand the intricate anatomy involved, how to diagnose these injuries and the most effective paths toward prevention and recovery. 

 

Complex Anatomy Behind a Common Injury 

The adductor muscle group includes six muscles on the medial thigh, with the adductor longus the most commonly injured. Recent anatomical studies have emphasized the importance of the pyramidalis  anterior pubic ligament – adductor longus complex (PLAC), a structure that helps explain why adductor injuries often extend beyond a simple tendon tear. In many athletes, proximal adductor injuries involve not only the tendon but also surrounding fibrocartilage and adjacent muscular connections such as the pectineus and gracilis. Understanding this complex relationship has allowed for more accurate diagnosis and improved treatment decision-making. 

 

Improving Diagnosis: Clinical Evaluation First 

The 2015 Doha agreement helped standardize the evaluation of groin pain by dividing it into five categories: adductor-related, iliopsoas-related, inguinal-related, pubic-related and hip-related. Because imaging often reveals abnormalities in asymptomatic athletes, clinical evaluation remains the cornerstone of diagnosis. Key diagnostic criteria for adductor-related groin pain include localized tenderness and pain reproduced with resisted adduction, often assessed with the adductor squeeze test. Differentiating true adductor injury from other causes of groin pain is essential for proper treatment planning. 

 

Role of Imaging in Identifying Injury Severity 

While clinical evaluation is primary, imaging (especially MRI) plays a critical role in classifying the severity and extent of injury. MRI can distinguish between muscle strains, partial tears and complete avulsions and can detect involvement of the PLAC. Validated systems such as the Serner classification and the British Athletics Muscle Injury Classification help predict return-to-play timelines. Ultrasound also serves as a valuable first-line tool for identifying tendon tears, especially in acute settings. 

 

Preventing Adductor Injuries 

Research has uncovered several strong risk factors for adductor injury: previous groin pain, reduced hip rotation and adductor muscle weakness. Strength deficits are among the most modifiable risks, making strengthening programs a central focus of prevention efforts. Some studies show significant reductions in injury rates when athletes engage in targeted adductor training, particularly preseason programs aimed at improving adductor-to-abductor strength ratios. Although findings from randomized trials are mixed, the overall evidence supports regular strength assessment and individualized strengthening routines for at-risk athletes. 

 

Nonoperative Treatment: The Standard for Most Athletes 

Most adductor injuries respond well to conservative treatment, making nonoperative care the first-line approach. Active rehabilitation, including strengthening of the adductors, core and pelvic stabilizers, has consistently proven superior to passive treatments such as stretching or electrotherapy. Landmark research shows that athletes who engage in structured, criteria-based rehabilitation programs not only return to sport more successfully but also maintain better outcomes many years later. 

 

Return-to-play timelines vary based on severity. Athletes with partial tears often resume sport within two to three weeks, while complete tears typically require eight to twelve weeks. Recurrence rates range from 5% to nearly 20% depending on the sport and injury type, but most athletes recover fully without lasting performance decline. 

 

When Surgery Becomes Necessary 

Surgical intervention is reserved for specific situations, such as acute avulsions with more than 2 cm of tendon retraction or chronic cases unresponsive to prolonged rehabilitation. Surgical options include direct repair of the adductor longus, partial release or complete tenotomy. All have demonstrated good success in high-level athletes, with return-to-play rates near 100% in many series. Repairs typically yield a return within 10 to 14 weeks, making this option especially attractive for professional athletes with complete avulsions. 

 

A Path Forward 

Adductor injuries are complex but treatable. A deepened understanding of anatomy, combined with standardized clinical evaluation and advanced imaging, allows clinicians to tailor treatment more effectively. Prevention strategies centered on strength and mobility screening reduce risk, while structured rehabilitation remains the foundation of care. When necessary, surgical repair or release can reliably restore athletes to their pre-injury level of performance. Continuing research will further refine diagnostic standards, rehabilitation protocols and operative indications, ultimately helping athletes recover faster and more safely.
