Objectives: Modern lateral extra-articular tenodesis (LET) has shown promising results at short term follow-up but there is a lack of studies investigating the incidence of complication and lateral osteoarthritis (OA) at long-term. The aim of the study was to compare in terms of failure rates, clinical outcomes and OA incidence three different ACL reconstruction techniques including hamstring single-bundle (HS group), patellar tendon (BTB) and hamstring over-the-top with LET (LET group). Methods: Seventy-five patients were randomized to receive one of the three ACL reconstruction techniques. At the last follow-up, patients reported outcomes (PROMs), complication and reoperation were collected for every patient. An objective clinical evaluation was performed including anteroposterior laxity measurement (KT-1000) and pivot shift quantification (PS, triaxial-accelerometer). Clinical failures were considered patients with evidence of graft rupture or those with KT-1000 side-to-side > 5mm or with PS side-to-side > >1mm/s2. A radiographic evaluation was performed to assess the incidence of tibiofemoral and patellar OA. Results: Final analysis was conducted on 61 patients (81.3%) at an average 23.0 ± 1.1 years follow-up, 38 patients completed the clinical and radiological evaluation. The LET group showed a higher Tegner score compared to the BTB (p=0.026), mean of 4.41 (up to 7) against 3.47 (up to 5). No difference was identified in the other clinical scores among the three groups (p>0.05). Revision rate and clinical failure were respectively 15.8% and 57.1% for the BTB group, 4.6% and 38.5% for the HS group and 4.6% and 18.8% for the LET group (P= 0.09 to 0.8, ns). No difference in the quantitative evaluation of the Pivot Shift were reported, while AP side-to-side difference was lower in the BTB group compared to the HS group (mean -0.1mm vs. +1.5mm). Finally, the BTB group showed a higher rate of patellofemoral OA compared to the other two groups (p=0,009) while the incidence of lateral OA was not increased in the LET group compared to the other techniques (p=0.50). Conclusions: Satisfactory clinical outcomes after ACL reconstruction at long-term follow-up could be achieved with different modern surgical techniques. However, the BTB graft was associated with increased incidence of patellofemoral OA when compared with the other techniques. Finally, LET was associated with increased sport participation and similar rate of lateral OA compared to other techniques at long-term follow-up. [ABSTRACT FROM AUTHOR] |
