Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

About six months after patella stabilizing 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. Furter is patients experience of living with patellar instability explored.

Return to Sport testbattery

At baseline, approximately 3 weeks before surgery and 6 months after surgery: patients conduct a testbattery consisting of 2 PROMs: the NPI-No and BPII2.0-No together with three physical tests: isokinetic strength tests, hop tests and Y-balance test. For the cross-cultural validation of NPI and BPII2.0 patients also conduct KOOS, IKDC 2000 and Tampa Scale.
