Brief Summary

The aim of the study is to investigate pain, function and quality of life before and 10-12 months after surgical repair and/or rehabilitation of hamstrings avulsion

Conditions

Hamstring Injury

Outcome Measures

Primary Outcomes (4)

• 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 Outcomes (3)

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

  Change from before surgery to 10-12 months after surgery

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

  Change from before surgery to 10-12 months after surgery

• Hip Sports Activity Scale (0-8 scale)

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

Interventions

Orthopaedic surgery and/or rehabilitation PROCEDURE

The avulsion is repaired and hereafter the patient follows rehabilitation. Some are treated conservatively and only follow rehabilitation.
