Effect of Exercise Rehabilitation Combined with Alfacalcidol Administration on Patellofemoral Traumatic Dysfunction.

Objective: To investigate the efficacy and clinical value of alfacalcidol combined with exercise rehabilitation in therapy of the postoperative dysfunction of patients with patella fractures.

Methods: In this study, 100 patients who underwent patella fracture surgery at Peking University People's Hospital between April 2018 and December 2019 were randomly selected and divided into a control group (n=50) and an experimental group (n=50) by lottery. The control group received exercise therapy, while the experimental group received alfacalcidol based on exercise rehabilitation. The functional assessment measure (FAM) score, visual analog scale (VAS) score, therapy efficiency, adverse effects, callus volume, and callus density were compared between the two groups.

Results: The FAM score and therapy efficiency in the experimental group were significantly higher than in the control group [P < .001, RR: 95%CI (10.28, 5.12 to 15.52)], but the VAS score was lower [P < .001 RR: 95% CI (22.83, 1.99 to 3.31)]. Patients in the experimental group had fewer adverse effects [P < .001, RR: 95% CI (14.62, 6.49 to 32.92)] than those in the control group but significantly larger callus volume and density [both P < .001, RR: 95% CI (26.03, 3.21 to 4.07): (17.92, 2.83 to 3.34)].

Conclusion: Alfacalcidol combined with exercise rehabilitation therapy could significantly improve motor function, callus volume, and callus density in patients with patella fracture, resulting in a high applicable value in managing postoperative functional impairment of patellar fractures.
