Abstract
The study was established to assess the long-term results and differences between autogenous and synthetic anterior cruciate ligament (ACL) reconstruction.
We randomised 50 patients into 2 groups: 26 (52%) underwent reconstruction with middle third patellar tendon graft (PTG) harvested using the ‘Graftologer’ (Neoligaments) and 24 (48%) underwent reconstruction with the Leeds-Keio ligament (LK).
Subjective knee function was assessed using the Lysholm score, Tegner activity score, IKDC grading, and clinical assessment of anterior knee pain. Laxity was tested clinically, including anterior draw at 20° (Lachman), pivot shift, and arthrometric measurements using the Stryker laxometer.
At five years we have noted no significant difference in Lysholm scoring and Pivot shift between the LK group and patellar tendon group. But there was a significant difference in Tegner activity level and IKDC activity scores with PTG faring better at five years. There is no significance difference in anterior knee symptoms between the groups.
Conclusion: Due to the success of PTG/Hamstring in routine primary ACL reconstruction there does not seem to be a role for artificial ligaments. However, if we just look at functional outcome and patient satisfaction, LK patients seem to be doing as well as PTG at five years. So, there may be a place for the Leeds Keio graft where autologous tissue is unavailable.
