Development of a Test Battery for Measurement of Knee Function in Patients With Patellar Instability

Development of a Test Battery for Measurement of Knee Function in Patients With Patellar Instability

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.
