Background: Lateral epicondylitis, commonly known as tennis
elbow, is a common musculoskeletal condition affecting the extensor tendons of
the forearm, specifically the common extensor tendon originating at the lateral
epicondyle of the humerus. Individuals engaged in professions or sports that
involve frequent and forceful use of the forearm, such as carpentry, painting,
or playing racquet sports, are at an increased risk.
Objective: The objective is to compare the efficacy, in
terms of pain relief and functional improvement, of autologous whole blood and
corticosteroid injection in managing lateral epicondylitis.
Methods: This was a comparative study conducted in the
Department of Orthopedics, National Institute of Medical Sciences Jaipur,
Rajasthan, India. Eighty patients diagnosed to be having lateral epicondylitis
were included in this study on the basis of predefined inclusion and exclusion
criteria. A detailed history was obtained in terms of the presence of any
chronic system illness such as hypertension, diabetes mellitus, arthritis, or
any autoimmune disorder. The patients were divided into 2 groups on the basis
of whether they were given autologous whole blood (Group B) or corticosteroid
injection (Group S). The efficacy of both the treatment modalities was compared
in terms of Pain relief (as assessed by a reduction in Visual Analogue Score
[VAS] score) and functional improvement (as assessed by an improvement in the
Mayo Elbow performance score). SSPS 22.0 software was used for statistical
analysis and p<0.05 was taken as statistically significant.
Results: A total of 80 patients were included in this study
out of which there were 37 (46.25%) males and 43 (53.75%) females with a M: F
ratio of 1:1.16. The mean age of patients in Group B and Group S was found to
be 52.36±9.98 years and 48.46±10.12 years, respectively. The mean age of
patients in both groups was found to be comparable with no statistically
significant difference (p=0.0866). In this study, till 2 weeks after injection,
the reduction in VAS score was found to be comparable in both groups. At the
time of 4 weeks, 8 weeks, and 12 weeks follow–up, the mean VAS score in Group B
was less as compared to Group S, and the difference was found to be
statistically highly significant (p<0.0001). At the time of 4 weeks, 8
weeks, and 12 weeks follow-up, the mean MEPS in Group B was more as compared to
Group S, and the difference was found to be statistically significant
(p<0.05).
Conclusion: It is concluded that both interventions
exhibited a favourable safety profile, with minimal and manageable adverse
effects. However, for lateral epicondylitis, whole blood injection demonstrated
superior efficacy in terms of pain relief and functional improvement as
compared to injection of corticosteroid.
