Abstract

Background: Lateral epicondylosis has been found to occur in approximately 2% of general population. It’s etiology and management still remains controversial. Various studies have shown benefits with local injection of autologous blood and polidocanol individually. However, there is paucity of studies comparing the results between these both, hence we envisage to compare the clinical and functional outcomes of local autologous blood versus polidocanol injection for the treatment of lateral epicondylosis of elbow.
Materials and methods: 60 patients (age group- 18 to 60 years)with clinically diagnosed lateral epicondylosis of elbow were enrolled for the study. They were randomized into 2 groups. Group I (n = 30) was treated with autologous blood injection and Group II (n = 30) with polidocanol injection after Nirschl staging. Patients were evaluated clinically at 6& 12 weeks after the injection and were again staged by Nirschl staging on both the visits.
Results: 34 patients successfully completed 12 weeks follow-up and were included in the analysis. It was observed that clinical outcomes in terms of Nirschl score at 6 and 12 weeks was better in Group I as compared to Group II. Statistical comparison between the two groups revealed that mean values of Nirschl score were lower in group I (4.41+1.004 and 3.71+1.532 at 6 weeks and 12 weeks of follow-up respectively) as compared to group II (4.76+1.300 and 4.47+1.281at 6 weeks and 12 weeks follow-up respectively). Down staging of disease symptom was clinically better in group I (16/17) as compared to group II (11/17). However the difference in the mean values of Nirschl score between the groups was not statistically significant (p=0.342).
Conclusion: Although autologous blood injection showed a better clinical improvement as compared to polidocanol injection, the difference was not statistically significant between these both.
