Tape versus cast for non-operative treatment of primary patellar dislocation: a randomized controlled trial

Purpose We hypothesized that taping results in better short-term functional outcome and comparable redislocation rates. Methods In a prospective randomised clinical trial, 18 patients with a primary patellar dislocation ≥18 years old without accompanying fractures or previous surgery to the knee were included. After 1 week of dorsal splinting, they were randomized into two groups: taping and cylinder cast immobilization. Physical examination and knee function according to the Lysholm Knee Scoring Scale were taken at 1-, 6- and 12-week and at 1- and 5-year follow-up. We also compared the redislocation rates. Results Taping resulted in a significantly better Lysholm score at 6 and 12 weeks post-dislocation ( P
