Introduction: Orthopaedicians treats the patients with local injection of corticosteroid (CS) will get the short term pain relief after, not for the long term. Platelet-rich plasma (PRP) injection for lateral epicondylitis (LE) reduces pain and induces healing of the common extensor tendon injury and vascularisation of the diseased tendon. Currently this study evaluates the treatment outcome results of the PRP injection when compared with CS in the treatment of LE.
Materials and Methods: Study was conducted at orthopedic department of Birds hospital, Tirupathi, Chitoor, A. P., with 40 patients of 20 cases in each group, Group A patients were injected with 2 ml of PRP was injected and In Group B 2 ml of methyl prednisolone (40 mg/ml) was injected at the most tender point over the lateral epicondyle of the humerus using the peppering technique and evaluation was carried out to assess the amount of the pain and the amount of disability in the pre-injection phase, and on subsequent consultations at 4 weeks, 12 weeks & 6 months (the final follow up). The pain was assessed by using the Visual Analogue scale (VAS) and the disability was assessed by Nirschl staging.
Results: Pre-injection, the mean VAS scores for pain and Nirschl stages were similar in group A and group B with P value of 0.74, mean Nirschl stage in group A and group B was 5.84 and 6.05 respectively with P value of 0.45. There was significant difference between the groups in VAS score (0.56 versus 1.88) and Nirschl stage (0.32 versus 1.84) at 6 months of follow up. At the six-month follow-up 90% patients had complete pain relief in group A in comparison to only 45% in group B. Seven out of 20 (35%) patients had recurrence of pain at 6 months of follow up in group B but none of patients reported recurrence of pain or disability in group A.
Conclusion: PRP appeared to enable biological healing of the lesion, whereas CS appeared to provide short term, symptomatic relief but resulted in tendon degeneration.
