Development of a Test Battery for Measurement of Knee Function in Patients With Patellar Instability
Study Details
Study Description
Brief Summary
About six months after patellastabilizing surgery postoperative restrictions are commonly lifted and patients may consider whether a return to activity/sports is feasible. Currently, there are no evidence-based criteria to determine a patients readiness for sports and/or activity (RTS) following stabilizing surgery. The purpose of this project was therefore to investigate the feasibility of a test battery to evaluate knee function in postoperative follow-up evaluation - and in RTS decisions - for patients with patellar instability. Banff Patellofemoral Instability Instrument 2.0 and Norwich Patellar Instability Score is being translated and validatend in a Norwegian population.

Outcome Measures
Primary Outcome Measures
- Banff Patellofemoral Instability Instrument 2.0 change from pre- to postopertaive score [Baseline and 6 months after surgery.]
Self-administered, disease-specific quality of life score. It will be administered as a patient completed questionnaire.
- Norwich patellar Instability score change from pre- to postopertaive score. [Baseline and 6 months after surgery.]
Patient-perceived symptoms of patellar instability during activity. It will be administered as a patient completed questionnaire.
Secondary Outcome Measures
- Forward step down test [Baseline and 6 months after surgery.]
Is performed on a 20-cm step and evaluates function and movement quality.
- Y-balance test [Baseline and 6 months after surgery.]
Evaluates knee stability and asymmetrical balance in three directions (anterior, posteromedial and posterolateral).
- Single legged hop tests [Baseline and 6 months after surgery.]
Comprises four tasks: single-leg hop for distance, triple hop for distance, triple cross-over hop for distance and six-meter timed hop.
- Isokinetic strength test [Baseline and 6 months after surgery.]
Strength testing of knee extension / flexion (Biodex system 4 dynamometer, Biodex Medical Systems Inc., Shirley, New York). With a standardized protocol of five repetitions at 60 o/sec and 30 repetitions at 240 o/sec.
- IKDC-2000 [Baseline and 6 months after surgery.]
Is a knee-specific, patient reported tool, including 18 questions across three domains: symptoms, physical activity and function. It will be administered as a patient completed questionnaire.
- KOOS [Baseline and 6 months after surgery.]
Is an instrument to assess the patient's opinion about their knee and associated problems. It comprises five domains: pain, other symptoms, function in daily living, function in sports and recreational activities and knee-related QOL. It will be administered as a patient completed questionnaire.
- Tampa scale of kinesiophobia [Baseline and 6 months after surgery.]
TSK is a 17-item patient-reported questionnaire aimed at quantifying the fear of re-injuries due to movement and physical activity. It will be administered as a patient completed questionnaire.
