[Intramuscular tendon injuries of the thigh: diagnostic evaluation, surgical treatment, and rehabilitation].

Intramuscular tendon injuries of the thigh muscles are a relatively common and significant problem in sports medicine, particularly in high-speed sports. MRI is a valuable tool for diagnosing and evaluating the severity of these injuries. Depending on the severity and chronicity of the injury, treatment options include conservative or surgical treatment. We present the typical MRI criteria for acute and chronic injuries to the intramuscular thigh tendons and provide a detailed description of the surgical treatment and technique. Both acute and chronic lesions can be successfully treated with surgery. In rehabilitation, MRI remains a valuable tool for monitoring, but functional tests such as EMG, force plate measurements and isokinetic testing should also be included. A return to competitive sport is typically possible within approximately four months.
