Efficacy of neural prolotherapy versus local corticosteroid soft tissue injection for treatment of chronic anserine bursitis: a prospective randomized clinical trial

Ain-Shams Journal of Anesthesiology

Table 4 Comparison between the two treatment groups regarding the degree of improvement of chronic anserine bursitis at the postinjection assessment visit

Degree of improvement	Group I (NP) (n = 34 lower limbs obtained from 22 patients) n(%)	Group II (CS) (n = 33 lower limbs obtained from 21 patients) n(%)	Test of significance	P
Improvement	30(88.2)^†	32(97.0)^‡	(X²) 1.850	0.356^§
Complete improvement	13(38.2)	20(60.6)	(X²) 3.353	0.089
Partial improvement	17(50.0)	12(36.4)	(X²) 1.268	0.327

NP neural prolotherapy group, n(%) number (percentage) of lower limbs, CS corticosteroid group, X² value of Chi-square test
*P is significant at < 0.05
^†No improvement was present among three patients (13.6%) with four lower limbs with chronic anserine bursitis (11.8%)
^‡No improvement was present among one patients (4.8%) with unilateral chronic anserine bursitis (3%)
