Background: The new tape locking screw (TLS) anterior cruciate ligament reconstruction technique is a variation on the widely used anteromedial portal (AMP) reconstruction technique. A difference between the AMP and the TLS technique is that the AMP technique uses both the semitendinosus and the gracilis tendon where the TLS technique uses the semitendinosus tendon only. The influence of using 1 or 2 hamstring tendons on muscle strength deficit at the long term remains questionable in the existing literature, and muscle strength deficit on the short term have not been studied. Purpose: To compare the muscle strength deficit between the AMP and TLS anterior cruciate ligament reconstruction techniques at the short term and to determine whether specific variables are related to muscle strength deficit. Methods: In this non-randomized comparative pilot study isokinetic muscle testing (at 60, 180 and 240 deg/sec flexion and 180 and 240 deg/sec extension) was performed 12 weeks postoperative to measure the muscle strength deficit. Results: 16 patients were included of which 5 patients in the TLS group and 11 patients in the AMP group. The only significant difference between groups was age. Except for the appearance of a significant relation (P0.009) in favor of the AMP technique between operation and peak torque deficit at 240 deg/sec extension when a correction was carried out concerning age, no significant differences between the groups but just trends were found in the other isokinetic strength deficit measures. Age and peak torque deficit turned out to be significantly related. No other variables were correlated to peak torque deficit. Conclusion: The study showed a significant relation between operation and peak torque deficit at 240 deg/sec in favor of the AMP technique, suggesting preoperative less quadriceps muscle strength deficit existed in patients operated with the AMP reconstruction technique. The flexion peak torque deficit did not show significant differences between groups but was on average less in the TLS group. This endorses the theory less hamstring muscle strength deficit occurs in the TLS group in comparison to the AMP group. Continuation of this pilot-study is recommended.
