|Procedure: Orthopaedic surgery and/or rehabilitation|The avulsion is repaired and hereafter the patient follows rehabilitation. Some are treated conservatively and only follow rehabilitation.|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Perth Hamstring Assessment Tool (PHAT) (0-100 scale) | Overall tool and pain subscale during sitting, steps and relaxing separately extracted. 0 indicates total problems and 100 no problems. | Change from before surgery to 10-12 months after surgery on the 0-100 scale. | 
| Knee flexion strength of affected leg (Newton meters per kilogram) | Maximal knee flexion strength of affected leg expressed as newton meters per kilogram, measured with a handheld dynamometer | Change from before surgery to 10-12 months after surgery | 
| Hip extension strength of affected leg (Newton meters per kilogram) | Maximal hip extension strength of affected leg expressed as newton meters per kilogram, measured with a handheld dynamometer | Change from before surgery to 10-12 months after surgery | 
| Overall health | 0-100 continuous scale (0 worst imaginable health, 100 best imaginable health) | Change from before surgery to 10-12 months after surgery on the 0-100 scale | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Knee flexion strength of contralateral leg (Newton meters per kilogram) | Maximal knee flexion strength of contralateral leg expressed as newton meters per kilogram, measured with a handheld dynamometer | Change from before surgery to 10-12 months after surgery | 
| Hip extension strength of contralateral leg (Newton meters per kilogram) | Maximal hip extension strength of contralateral leg expressed as newton meters per kilogram, measured with a handheld dynamometer | Change from before surgery to 10-12 months after surgery | 
| Hip Sports Activity Scale (0-8 scale) | Type of activity before injury and present 0, no activity, 8 athlete level. | Change from before surgery to 10-12 months after surgery on the 0-8 scale |
