HamRepair: Clinical and Functional Outcomes at Least 2 Years After Hamstring Muscle Repair
This study is to evaluate functional outcomes of a new, intraoperative lateral positioning of the anchors on the tuber ischiadicum, in comparison to regular anatomical anchoring direct on top of the tuber ischiadicumafter hamstring muscle repair.
This study is to quantify at least 2 years postoperative functional, biomechanical and clinical outcomes including side-to-side differences in muscle strength, unipedal balance, gait, jumping and squatting function, muscle activity, in patients treated by hamstring muscle repair.

Detaljert beskrivelse
The design of this pilot study is a descriptive cross-sectional single centre analysis involving all patients previously treated with hamstring repair.
All of these patients will be asked to participate in clinical and detailed functional analysis at least 2 years after surgery.
Specifically, biomechanical and functional data including isokinetic muscle strength, clinical scores, ROM, joint kinematics and kinetics during walking, running, squatting and single leg jumps, muscle activity and single leg balance ability in the affected and contralateral leg will be collected.
These parameters will be compared between legs and correlated with clinical scores.

Perth Hamstring Assessment Tool
Tidsramme: at baseline (total timeframe for each participant approx 20 minutes)
|
The Perth Hamstring Assessment Tool (PHAT) is to evaluate functional outcomes of proximal hamstring re-attachment surgery.
The PHAT provides a score out of 100, with a higher score corresponding to higher function.
The questionnaire uses a visual analogue scale for pain scores as well as categorical scores for activity levels.

EQ-5D-5L
Tidsramme: at baseline (total timeframe for each participant approx 20 minutes)
|
The EQ-5D-5L essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).
The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems.

|
Lower Extremity Functional Scale (LEFS)
Tidsramme: at baseline (total timeframe for each participant approx 20 minutes)
|
The Lower Extremity Functional Scale (LEFS) is intended to assess functional status in patients with disability of the lower extremity.
It is a 20 item questionnaire.
The maximum score obtainable is 80 which means complete function and the lowest score is 0 which means very low and severely impaired function.
