[Comparative study of anterior cruciate ligament reconstruction between the One Band and U-Two techniques].

Introduction: ACL injuries are found within the most common ligament injuries. This has led to the development of different surgical techniques to restore knee stability.

Material Y Methods: Clinical study, randomized, blind comparing ACL reconstruction techniques with One Band and «U-Two» using clinical scales and arthrometria with KT-1000 and Pivot Shift Meter.

Results: Of 36 patients, 52.94% was drawn for the One Band technique and 47.06% for «U-Two». 11.76% of patients had a displacement greater than 11mm in the affected knee with KT-1000. 8.82% showed an equal anterior displacement on both knees. One patient had a major previous displacement after reconstruction surgery with the one band technique, but with improvement on clinical scales. Pivot Shift measurements found a difference in displacement greater than 4,000 m/s on the X axis following the One Band technique compared to the healthy knee calculating integrals, while with U-Two the difference was less than 600 m/s. On the Y axis a difference of 3,500 m/s was found between the healthy and the injured leg, which decreases to less than 2,000 m/s after reconstruction using U-Two technique.

Conclusions: Differences have been found throughout the study in patient evolution, indicating that repair using the U-Dos technique has better results in recovering the anteroposterior and rotational stability of the affected limb.
