Objectives: To compare the functional outcome of biceps tenotomy vs biceps tenodesis as an operative treatment for Long head of biceps tendon lesions associated with rotator cuff injuries and study the associated complications. Materials and Methods: 30 arthroscopic shoulder surgeries were performed at Sanjay Gandhi Institute of Trauma and Orthopedics from November 2020 to June 2022. 15 patients of Tenotomy and 15 patients of Tenodesis of biceps tendon associated with rotator cuff injuries. All patients were evaluated pre-operatively & post-operatively with VAS score, ASES score and CONSTANT score. Average pre-operative ASES score was 33.43 & CONSTANT score was 33.66. Follow up period ranged from 6 months to 12months. Results: 15 (60.0%) of the participants had Group: Tenotomy. 10 (40.0%) of the participants had Group: Tenodesis. The mean Age (Years) was 49.36 ± 12.28. 8 (32.0%) of the participants had Age Group: <40 Years. 17 (68.0%) of the participants had Age Group: >40 Years. 17 (68.0%) of the participants had Gender: Male. 8 (32.0%) of the participants had Gender: Female. The mean Duration of Symptoms (Months) was 6.44 ± 6.48. The mean VAS (Pre-Operative) was 8.64 ± 0.49. The mean VAS (6 Weeks) was 7.24 ± 0.44. The mean VAS (12 Weeks) was 5.08 ± 0.57. The mean VAS (18 Weeks) was 3.84 ± 0.55. The mean VAS (24 Weeks) was 3.48 ± 0.59. The mean ASES Score was 81.52 ± 5.33. The mean CONSTANT Score was 79.36 ± 6.16. There was statistically significant improvement in the trend of VAS Score, ASES Score and CONSTANT Score over time in each group but it was favourable towards the Tenodesis group in younger patients. Conclusion: In conclusion the ASES Scores and the CONSTANT Scores were higher in the Tenodesis group when compared to the tenotomy group respectively. Correspondingly, the improvement in the Visual Analogue Scale suggested an increased patient satisfaction in both the groups. Tenodesis can be a considered as a favourable option to treat young patients with long head of biceps tendon lesion with RCTs.
