Table 1 Determinants having an effect on the time to return to play after hamstring muscle complex injury in athletes (according to [16])
Clinical determinants | MRI determinants | US determinants |
|---|---|---|
• Stretching-type injuries | • Positive findings | • Large cross-sectional area |
• Recreational-level sports | • Higher grade of injury | • Injury outside the musculotendinous junction |
• Structural versus functional injuries | • Muscle involvement > 75% | • Hematoma |
• Greater range of motion deficit with the hip flexed at 90° | • Complete transection | • Structural injury |
• Time to first consultation > 1 week | • Retraction | • Injury involving the biceps femoris |
• Increased pain on the visual analog scale | • Central tendon disruption of the biceps femoris |  |
• > 1 day to be able to walk pain free after the injury | • Proximal tendon involvement |  |
• Shorter distance to the ischial tuberosity |  | |
• Length of the hamstring injury |  | |
• Depth, volume, and large cross-sectional area |  |
