title: Tape versus cast for non-operative treatment of primary patellar dislocation: a randomized controlled trial.
abstract: OBJECTIVE
  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 < 0.05), and also after 5-year follow-up (P < 0.01). Knee function was better at 1-year follow-up. There were no cases of recurrent dislocation.
  
  
  CONCLUSIONS
  Tape bandage immobilization seems superior to a cylinder cast even after 5 years.
