Primary outcomes

  1. Perth Hamstring Assessment Tool (PHAT) (0-100 scale)

    Time frame: Change from before surgery to 10-12 months after surgery on the 0-100 scale.

    Overall tool and pain subscale during sitting, steps and relaxing separately extracted. 0 indicates total problems and 100 no problems.

  2. Knee flexion strength of affected leg (Newton meters per kilogram)

    Time frame: Change from before surgery to 10-12 months after surgery

    Maximal knee flexion strength of affected leg expressed as newton meters per kilogram, measured with a handheld dynamometer

  3. Hip extension strength of affected leg (Newton meters per kilogram)

    Time frame: Change from before surgery to 10-12 months after surgery

    Maximal hip extension strength of affected leg expressed as newton meters per kilogram, measured with a handheld dynamometer

  4. Overall health

    Time frame: Change from before surgery to 10-12 months after surgery on the 0-100 scale

    0-100 continuous scale (0 worst imaginable health, 100 best imaginable health)

Secondary outcomes

  1. Knee flexion strength of contralateral leg (Newton meters per kilogram)

    Time frame: Change from before surgery to 10-12 months after surgery

    Maximal knee flexion strength of contralateral leg expressed as newton meters per kilogram, measured with a handheld dynamometer

  2. Hip extension strength of contralateral leg (Newton meters per kilogram)

    Time frame: Change from before surgery to 10-12 months after surgery

    Maximal hip extension strength of contralateral leg expressed as newton meters per kilogram, measured with a handheld dynamometer

  3. Hip Sports Activity Scale (0-8 scale)

    Time frame: Change from before surgery to 10-12 months after surgery on the 0-8 scale

    Type of activity before injury and present 0, no activity, 8 athlete level.
