About this trial

Microinstability of the hip joint is an important cause of hip pain and reduced hip function in young and active individuals. Hip microinstability is due to extraphysiologic hip motion and could be secondary to acetabular dysplasia, connective tissue disorder, macrotrauma, microtrauma, iatrogenic- and idiopathic causes. Treatment for hip microinstability is initiated with non-surgical treatment consisting of physiotherapy aimed mainly at stability. If non-surgical treatment fails, surgery with arthroscopic plication of the hip joint capsule is the preferred method. This study evaluates non-surgical and arthroscopic treatment for hip microinstability regarding hip function and adverse events.

Trial outcomes

Primary outcomes

1

Mean Change from Baseline in Hip Function on the International Hip Outcome Tool (iHOT-12) at 24 Months

Participant-reported hip function. Minimum score 0, maximum score 100 (higher score mean a better outcome).

Time frame
24 Months
2

Mean Change from Baseline in Hip Function on the Copenhagen Hip and Groin Outcome Score (HAGOS) at 24 Months

Participant-reported hip function. Minimum score 0, maximum score 100 (higher score mean a better outcome).

Time frame
24 Months
3

Mean Change from Baseline in Maximal Isometric Hip Muscle Force in Newton at 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.

Time frame
24 Months
4

Mean Change from Baseline in Hop Performance at 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.

Time frame
24 Months

Secondary outcomes

1

Mean Change from Baseline in Hip Function on the EuroQoL-5 Dimensions (EQ-5D) at 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).

Time frame
24 Months
2

Mean Change from Baseline in Hip Function on the Hip Sport Activity Scale (HSAS) at 24 Months

Participant-reported sport activity level. Minimum score 0, maximum score 8 (higher score mean a higher sport activity level).

Time frame
24 Months
3

Type and Number of Adverse Events at 24 Months

Adverse events collected via phone interview.

Time frame
24 Months
4

Single Question "Satisfied with Treatment?" at 24 Months

Participant-reported satisfaction with treatment (yes/no).

Time frame
24 Months
