Eligibility

Sex/Gender

All

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: -indication for isolated gluteal tendon refixation without accompanying additional surgical measures in the hip joint area -patient age = 18 years

Exclusion criteria

Exclusion criteria: -Symptomatic accompanying pathologies of the hip joint to be treated -symptomatic, but radiologically significant degenerative, congenital or surgically induced changes in the hip joint to be treated (e.g. coxarthrosis grade 3 or higher according to Kellgren and Lawrence, higher grade hip dysplasia with CE angle <20°, after osteotomy or endoprosthetic treatment) -accompanying diseases that have an influence on the gait pattern -obesity, which makes it impossible to carry out a valid gait analysis (guideline value BMI <30-35, depending on fat distribution pattern).

Design outcomes

Primary

Measure	Time frame
The primary endpoint is defined as the difference between the modified Harris Hip Score (mHHS) at 12-month follow-up and the mHHS at preoperative assessment. The hypothesis is that surgery is expected to improve the mHHS.	—

Secondary

Measure	Time frame
Secondary goals are the acquisition of: -pain on the visual analogue scale and other clinical scores Harris Hip Score and Western Ontario and McMaster Osteoarthritis Index, WOMAC VA, International Hip Outcome Tool 33 -iHOT33, Nonarthritic Hip Score -NAHS) -hip abduction strength and the ability to stabilize the pelvis in the monopedal position during the clinical examination -gait analysis parameters to objectify the gait pattern -maximum hip abduction moment in isokinetic force measurement -Gathering of serological parameters to be investigated as biomarkers for correlation with tendon healing.	—
