In this study, we compared the functional outcome of repair of cut flexor tendons using modified Kessler technique versus the four stands technique. Patients and Methods: Thirty Two adult patients with forty one severed flexor tendon underwent primary tendon repair. In group A, we used two strands repair technique and in group B we used four strand repair technique. We used early controlled physiotherapy rehabilitation protocols for both groups. Results: Regarding total active range of motion and DASH score, there were no statistically significant differences between the outcomes of these two groups. Tendon rupture occurred in one case in group A. Discussion: Primary tendon repair is the optimum treatment for cut flexor tendons. However, several repair techniques and rehabilitation protocols exist. In vitro tests concluded that the more the strands that cross the repair site, the stronger the repair but in vivo studies did not reflect such benefits except the four strands technique. Conclusion: We were not able to identify any statistically significant differences in total active motion and DASH scores between two and four strands repair techniques. However, the results of four strands technique were more favorable.
