- Mean Change from Baseline in Hip Function on the International Hip Outcome Tool (iHOT-12) at 24 Months [ Time Frame: 24 Months ]Participant-reported hip function. Minimum score 0, maximum score 100 (higher score mean a better outcome).
- Mean Change from Baseline in Hip Function on the Copenhagen Hip and Groin Outcome Score (HAGOS) at 24 Months [ Time Frame: 24 Months ]Participant-reported hip function. Minimum score 0, maximum score 100 (higher score mean a better outcome).
- Mean Change from Baseline in Maximal Isometric Hip Muscle Force in Newton at 24 Months [ Time Frame: 24 Months ]Maximal hip isometric muscle force will be assessed using a dynamometer (Hoggan MicroFET2, Hoggan, Scientific L.L.C., Salt Lake City, USA) for hip flexion, adduction, abduction, and extension. The maximal developed force in Newton will be recorded. Higher Newton value means a better outcome.
- Mean Change from Baseline in Hop Performance at 24 Months [ Time Frame: 24 Months ]Hop performance will be measured with 3 single-leg hops: vertical hop (Muscle lab, Ergotest Technology, Oslo, Norway), hop for distance and a 30-second side-hop test. Each hop test is performed with the patients holding their hands behind their back. For the vertical hop, the time from take-off to landing is converted into hop height in centimeters. In the hop for distance test, the distance between top of the toes at take-off to heel at landing is measured in centimeters. For the 30 second side hop test, one trial per leg is allowed, where the patient is instructed to hop as many times as possible over 2 lines 40 centimeters apart. The number of hops is recorded. Higher height, longer distance and higher number of hops means a better outcome.
- Mean Change from Baseline in Hip Function on the EuroQoL-5 Dimensions (EQ-5D) at 24 Months [ Time Frame: 24 Months ]Participant-reported health-related quality of life. Minimum score 0, maximum score 1 (higher score mean a higher health-related quality of life).
- Mean Change from Baseline in Hip Function on the Hip Sport Activity Scale (HSAS) at 24 Months [ Time Frame: 24 Months ]Participant-reported sport activity level. Minimum score 0, maximum score 8 (higher score mean a higher sport activity level).
- Type and Number of Adverse Events at 24 Months [ Time Frame: 24 Months ]Adverse events collected via phone interview.
- Single Question "Satisfied with Treatment?" at 24 Months [ Time Frame: 24 Months ]Participant-reported satisfaction with treatment (yes/no).
