The aim of the study was to compare the effects of corticosteroid
injection with lidocaine injection in treating tennis elbow.
DESIGN: It is a
prospective, double-blinded, randomized controlled trial. Patients with tennis
elbow for more than 1 mo were recruited from a hospital-based rehabilitation
outpatient clinic. A total of 70 patients were recruited, and 61 patients
completed the study. Patients received an injection of either 10 mg (1 ml) of
triamcinolone (corticosteroid group, n = 30) or 1 ml of 1% lidocaine (lidocaine
group, n = 31). All of the outcome measures were evaluated before the
intervention and at 2 wks and 2 mos after treatment. RESULTS: No significant
group differences were observed between the corticosteroid and lidocaine groups
regarding Patient-Rated Tennis Elbow Evaluation, Disability of the Arm, Shoulder,
and Hand, visual analog scale for pain, and grip strength at baseline and at 2
wks and 2 mos after treatment (P > 0.05). However, within-group comparison showed
significant improvement after injection with regard to Patient-Rated Tennis Elbow
Evaluation, Disability of the Arm, Shoulder, and Hand, visual analog scale for
pain, and grip strength in both groups (P > 0.05). CONCLUSIONS: No differences in
the short-term outcomes were found between lidocaine and corticosteroid injection
in a small sample of people with tennis elbow with mean duration of 3.8 mos.
