Abstract
Lateral epicondylitis (tennis elbow) is a major cause of musculoskeletal pain involving common extensor origin of the forearm. This study was done to determine the effects of platelet-rich plasma on 15 patients with lateral epicondylitis. Selected patients were given intralesional platelet-rich plasma injection, activity of daily living instructions and paracetamol. Patients were assessed every 14 days interval by visual analogue scale, and the patient rated tennis elbow evaluation. Treatment response according to visual analogue scale and patient rated tennis elbow evaluation tool, the difference of improvement was found in respect to time, from pretreatment W1 (just before 1st Intervention) score to W11 score in every alternate week (p<0.005). This indicates that intralesional platelet-rich plasma is effective in the patients with lateral epicondylitis of elbow.
Highlights
One of the most common causes of musculoskeletal pain is the lateral epicondylitis, which involves common extensor origin of the forearm
W9 vs W11 score was 1.4 ± 0.6 vs 0.5 ± 0.5 respectively (p=0.000). This indicates that intralesional platelet-rich plasma was effective in lateral epicondylitis of elbow (Table II)
W9 vs W11 score was 12.9 ± 5.5 vs 4.2 ± 3.1 respectively (p=0.000)
Summary
One of the most common causes of musculoskeletal pain is the lateral epicondylitis, which involves common extensor origin of the forearm. Its incidence and prevalence are 1-3% and 10% respectively on general population among working people aged over 45 years old with high-risk jobs (strenuous for the arms).[1, 2] It arises due to repetitive manual work involving overexertion of wrist and finger extensors and imparts significant disability in terms of quality of daily life activities. Non-surgical treatment includes rest, physiotherapy, epicondylar counterforce braces, non-steroidal anti-inflammatory drugs, corticosteroid injection, autologous blood injection, platelet-rich plasma injection, percutaneous radiofrequency thermal treatment, extracorporal shock wave therapy, use of low-level laser therapy, acupuncture and botulinum toxin A injection.[4,5,6,7]
