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 < 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.
Conclusion:
Tape bandage immobilization seems superior to a cylinder cast even after 5 years.
