Background Local depot steroid injections can consistently and predictably relieve tennis elbow pain in the short term. Prolotherapy, extracorporeal shockwave therapy, autologous blood, and local injections of platelet-rich plasma (PRP) are examples of novel treatment approaches. Objective The objective of this study is to compare the effectiveness of autologous blood injection and local steroid injection in providing pain relief for patients with lateral epicondylitis (tennis elbow) using the visual analog scale (VAS) over 12 weeks. Methods A descriptive case series was conducted from July 10, 2019, to July 9, 2021, at the Department of Orthopaedic and Spine Surgery, Ghurki Trust Teaching Hospital. A total of 396 patients with tennis elbow, aged 20 to 50 years, were included (198 in each group). Patients managed with non-operative methods and those with other associated injuries in the same elbow were excluded. Group I received an injection of 40 mg of methylprednisolone acetate with 1 ml of 2% lignocaine solution. Group II received an injection of 2 ml of autologous venous blood. The final outcome was assessed at 12 weeks. Results In Group I, the average age of the patients was 36.04 ± 8.26 years, while in Group II, it was 37.23 ± 7.32 years. The male-to-female ratio was 2.3:1; 276 (69.81%) of the 396 patients were male, while 120 (30.19%) were female. Group I's mean baseline VAS score was 6.99 ± 0.99, while Group II's mean baseline VAS score was 6.99 ± 1.06 (p = 1.000). Group I had a mean post-therapy VAS score of 3.11 ± 1.62, while Group II had a mean score of 2.48 ± 1.26 (p = 0.0001). About 118 (59.60%) individuals in Group I and 156 (78.79%) patients in Group II experienced pain alleviation from lateral epicondylitis (p = 0.0001). Conclusion This study found that autologous blood injection significantly reduces pain in patients with lateral epicondylitis compared to steroid injection, with a statistically significant p-value of 0.0001. Pain relief was more frequent in the autologous blood group (78.79%) than in the steroid group (59.60%). These findings suggest that autologous blood injections may offer a more effective treatment, reducing the need for repeat procedures and improving patient outcomes.
