Complications of Hamstring Injury
The potential complications of hamstring injury range from delayed recovery to long-term dysfunction and chronic pain. Addressing these risks early in the treatment and rehabilitation process is crucial for minimising negative outcomes. Understanding the complications of hamstring injury also helps clinicians and patients make informed decisions about return-to-play readiness and long-term muscular health.
One of the most common complications is re-injury. Recurrence rates for hamstring strains are among the highest for muscle injuries in sports, often due to premature return to activity, incomplete rehabilitation, or unresolved muscle imbalances. Re-injury usually occurs within the first two months post-recovery and is often more severe than the initial strain.
Another significant complication is chronic tendinopathy. In cases where the proximal hamstring tendon is affected, persistent inflammation and microtrauma can lead to degenerative changes, resulting in ischial tuberosity pain or high hamstring tendinopathy. This condition causes deep buttock pain that worsens with sitting, running, or stretching the hamstring. Management often requires prolonged therapy, activity modification, and, in severe cases, surgical intervention.
Muscle scarring and fibrosis can also impair recovery. Following a moderate or severe injury, the body forms scar tissue as part of the healing process. This tissue lacks the elasticity and contractile ability of normal muscle, creating weak points that reduce performance and increase the risk of re-injury. Techniques such as manual therapy, massage, and progressive eccentric loading may help remodel scar tissue more functionally.

Inadequate rehabilitation can result in long-term strength deficits and asymmetry. Without targeted strengthening of the injured muscle and its synergists, the affected leg may remain weaker and more susceptible to future injury. This imbalance may also affect gait mechanics, increasing the strain on other joints and muscles in the kinetic chain.
Neurological complications, though rare, may arise if the sciatic nerve is involved. Direct trauma, excessive swelling, or scar tissue encasing the nerve can lead to symptoms such as radiating pain, numbness, tingling, or muscle weakness. These symptoms warrant immediate investigation with imaging and may require surgical decompression if conservative treatment fails.
Psychological effects are another important, often overlooked, complication. Athletes recovering from a significant hamstring injury may struggle with fear of re-injury, anxiety about performance, and loss of identity. Mental health support and gradual exposure to training loads can help overcome these barriers.
Surgical complications, while infrequent, must also be considered. These include infection, delayed wound healing, nerve damage, or failure of tendon reattachment. Skilled surgical technique and post-operative monitoring are key to reducing these risks.
Complications of Hamstring Injury
In summary, the complications of hamstring injury can be wide-ranging and debilitating if not properly managed. Early intervention, complete rehabilitation, and careful monitoring during return to activity are essential to prevent long-term issues and ensure optimal recovery outcomes.
