A prospective, randomized, placebo-controlled, pilot study was conducted to determine the efficacy of chiropractic patella mobilization in the treatment of patellofemoral pain syndrome. Thirty subjects were randomly allocated into two treatment groups. Group A received patella mobilization and group B received detuned ultrasound. Objective data to assess patient progress were obtained with the algometer. Subjective data were obtained by the McGill Pain Questionnaire, Numerical Pain Rating Scale-101, and the Patient-Specific Functional Scale. The nonparametric Mann-Whitney U-test and Wilcoxin Sign-Rank test were used for intergroup and intragroup statistical data, respectively. From the intragroup comparisons, group A showed a better statistical response to treatment than group B, subjectively and objectively. Although subjectively there was minimal intergroup difference, comparison of algometer findings revealed statistically significant differences objectively in favor of group A. The study concluded that patella mobilization was superior to placebo in the treatment of patellofemoral pain syndrome.
