Adductor Longus Tendon Tear: Symptoms, Diagnosis, and Treatment

Introduction

Adductor longus tendon tears are a significant cause of groin pain in athletes, particularly those involved in sports requiring quick changes of direction or powerful leg movements. Understanding the symptoms, diagnosis, and treatment options for this injury is crucial for proper management and a successful return to sports.

Symptoms of Adductor Longus Tendon Tear

Recognizing the symptoms of an adductor longus tendon tear is the first step towards proper diagnosis and treatment. Common symptoms include:

• Acute groin pain, often described as a "popping" sensation during activity
• Tenderness and swelling in the groin area
• Weakness in hip adduction (bringing the leg towards the midline)
• Pain when lying on the affected side
• Difficulty with activities like running, kicking, or changing directions

According to Serner et al. (2018), adductor longus injuries typically occur at three main locations: the proximal insertion (26%), the intramuscular musculotendinous junction of the proximal tendon (26%), and the musculotendinous junction of the distal tendon (37%).

Diagnosis of Adductor Longus Tendon Tear

Accurate diagnosis of an adductor longus tendon tear involves a combination of clinical examination and imaging studies:

1. Physical Examination: A healthcare provider will assess pain, swelling, and strength in the affected area. Specific tests, such as the adductor squeeze test, can help evaluate the injury.
2. Magnetic Resonance Imaging (MRI): MRI is considered the gold standard for diagnosing adductor tendon tears. Serner et al. (2021) found that MRI can accurately depict the location and extent of the injury.
3. Ultrasound: While less detailed than MRI, ultrasound can be useful for quick, dynamic assessment of the tendon.

Treatment Options

Treatment for adductor longus tendon tears depends on the severity of the injury and the patient's activity level. Options include:

1. Conservative Management

For partial tears or less severe injuries, conservative treatment is often the first line of approach. This may include:

• Rest and activity modification
• Ice and compression to reduce swelling
• Physical therapy to improve strength and flexibility
• Non-steroidal anti-inflammatory drugs (NSAIDs) for pain relief

2. Surgical Intervention

In cases of complete tears or when conservative treatment fails, surgical repair may be necessary. Gill et al. (2020) reported that surgical repair of adductor longus tendon tears in athletes resulted in a 97% return to sport rate, with 94% returning to their previous level of play.

Recovery and Rehabilitation

Regardless of the treatment approach, a structured rehabilitation program is crucial for optimal recovery. This typically includes:

• Progressive strengthening exercises
• Flexibility and range of motion work
• Sport-specific training
• Gradual return to activity

The timeline for return to sport can vary, but Gill et al. (2020) found that athletes typically returned to play around 12 weeks after surgical repair.

Conclusion

Adductor longus tendon tears can be a significant setback for athletes, but with proper diagnosis and treatment, a full return to sport is often possible. Early recognition of symptoms, accurate diagnosis through clinical examination and imaging, and appropriate treatment selection are key to optimal outcomes. Whether managed conservatively or surgically, a comprehensive rehabilitation program is essential for regaining strength, flexibility, and function, ultimately allowing athletes to return to their pre-injury level of performance.
