- Clinical Outcomes of Posterolateral Complex Reconstruction Performed with a Single Femoral Tunnel(2021) HELITO, Camilo Partezani; SOBRADO, Marcel Faraco; GIGLIO, Pedro Nogueira; BONADIO, Marcelo Batista; PECORA, Jose Ricardo; GOBBI, Riccardo Gomes; CAMANHO, Gilberto Luis; ANGELINI, Fabio JansonThe objective of this study is to report the functional outcomes, complications, and reconstruction failure rate of patients undergoing posterolateral complex reconstruction with a single femoral tunnel technique. Patients with posterolateral complex injuries associated with injury of the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), or both undergoing surgical treatment with the single femoral tunnel technique were included in the study. The International Knee Documentation Committee (IKDC) and Lysholm's scales were evaluated, in addition to age, gender, time between trauma and surgery, trauma type, range of motion (ROM) restrictions, peroneal nerve injury, and reconstruction failure. Sixty-six patients were included. Eighteen underwent ACL and posterolateral complex (PLC) reconstruction (group 1), 24 underwent ACL, PCL, and PLC reconstruction (group 2), and 24 underwent PCL and PLC reconstruction (group 3). The mean follow-up was 63 months. The subjective IKDC was 83.7 +/- 14.6 for group 1, 74.3 +/- 12.6 for group 2, and 66.3 +/- 16.0 for group 3 ( p <0.001). The Lysholm's score was 87.112.8 for group 1, 79.5 +/- 15.0 for group 2, and 77.7 +/- 15.2 for group 3 ( p =0.042). There were six reconstruction failures among the patients (9.1%) with no differences among the groups ( p =0.368). Female gender and reconstruction failure were associated with worse outcomes. Patients undergoing reconstruction of PLC structures with the single femoral tunnel technique achieved good functional outcomes and a failure rate similar to literature. Patients undergoing only combined ACL reconstruction showed better outcomes than patients undergoing combined PCL reconstruction. Female gender was associated with a worse functional outcome irrespective of the injury type.
- High Incidence of Osteoarthritis Observed in Patients at Short- to Midterm Follow-Up after Delayed Multiligament Knee Reconstruction(2022) SOBRADO, Marcel Faraco; GIGLIO, Pedro Nogueira; BONADIO, Marcelo Batista; PECORA, Jose Ricardo; GOBBI, Riccardo Gomes; ANGELINI, Fabio Janson; HELITO, Camilo PartezaniThe aim of this study was to evaluate the incidence of knee osteoarthritis, failure rate of reconstruction, and clinical outcomes of patients with chronic multiligament knee injuries subjected to surgical treatment. Sixty-two patients with chronic knee dislocation subjected to multiligament reconstruction between April 2008 and July 2016 were evaluated, with a minimum follow-up of 24 months. Anteroposterior and lateral radiographs were performed in the pre- and last postoperative evaluation; the progression of degenerative changes according to the Kellgren-Lawrence classification (KL) was assessed. The Schenck classification, Knee Injury and Osteoarthritis Outcome Score (KOOS), time between injury and surgery, type of postoperative rehabilitation protocol (brace vs. external fixator), and physical examination for ligament instability were also evaluated. Univariate and multivariate analysis were performed, p <0.05 was considered significant. Fifty-two (83.9%) patients were men and 16.1% ( n =10) were women, with a mean age of 38.81.3 years. The time from injury to surgery was 31.1 +/- 6.1 months, and the follow-up time was 6.1 +/- 0.5 years. The mean final KOOS was 79.3 +/- 10.4 and the overall reconstruction failure occurred in 25.8%. Of all patients, 64.5% ( n =40) presented a KL classification of >= 2 and were defined as having radiographic osteoarthritis (OA). As 11.7% ( n =7) also presented arthritis in the contralateral knee, in 53.2% ( n =33) the progression was most likely due to the initial injury. The failure of ligament reconstruction or residual instability was present in 15 (35.7%) of patients with OA, and only one patient (4.5%) without OA. In the multivariate analysis, only reconstruction failure was an independent predictor of OA (odds ratio=13.2 [ p =0.028]). There is a high incidence of knee OA following ligament reconstruction for chronic multiligament knee injuries. Ligament reconstruction failure was the only independent predictor for the development of OA in our study.
- Anatomical Risk Factors for Anterior Cruciate Ligament Injury Are Not Important As Patellar Instability Risk Factors in Patients with Acute Knee Injury(2022) GOBBI, Riccardo Gomes; VIDEIRA, Livia Dau; SANTOS, Anderson Albuquerque dos; SARUHASHI, Marcello Barni; LUCARINI, Bruno Romano; FERNANDES, Renan Jose Rodrigues; GIGLIO, Pedro Nogueira; PECORA, Jose Ricardo; CAMANHO, Gilberto Luis; HINCKEL, Betina BremerTo compare in magnetic resonance imaging the anatomical risk factors for anterior cruciate ligament (ACL) injury and patellar dislocation among patients who suffered acute knee injury, 105 patients with acute knee injury resulting in 38 patellar dislocations (patella group), 35 ACL injuries (ACL group), and 32 meniscus or medial collateral ligament injuries (control group) were included. These groups were compared for risk factors for patellar dislocation (patellar height, trochlear dysplasia, and quadriceps angle of action) and for ACL injury (intercondylar width, posterior inclination of tibial plateaus, and depth of the medial plateau). Univariate analysis found statistically significant differences ( p <0.05) between the patella and ACL groups in patellar height (Caton-Deschamps [CD] 1.23 vs. 1.07), trochlear facet asymmetry (55 vs. 68%), PTTG (13.08 vs. 8.01mm), and the patellar tip and trochlear groove (PTTG) angle (29.5 vs. 13.71 degrees). The patella group also differed from control in medial plateau inclination (4.8 vs. 1.87 degrees), patellar height (CD 1.23 vs 1.08), trochlear facet asymmetry (55 vs. 69%), lateral trochlear inclination (17.11 vs. 20.65 degrees), trochlear depth (4.1 vs. 6.05mm), PTTG (13.08 vs. 9.85mm), and the PTTG angle (29.5 vs. 17.88 degrees). The ACL and control groups were similar in all measures. Multivariate analysis found the following significant determinants between the Patella and Control groups: patellar height (CD index, odds ratio [OR]: 80.13, p =0.015), trochlear anatomy (asymmetry of facets M/L, OR: 1.06, p =0.031) and quadriceps action angle (PTTG angle, OR: 1.09, p =0.016); between the ACL and control groups: PTTG angle (OR: 0.936, p =0.04) and female gender (OR: 3.876, p =0.032); and between the patella and ACL groups, the CD index (OR: 67.62, p =0.026), asymmetry of the M/L facets (OR: 1.07, p =0.011) and PTTG angle (OR: 1.16, p <0.001). In conclusion, in patients with acute knee injury, the anatomical factors patellar height, trochlear dysplasia, and quadriceps angle of action were related to the occurrence of patellar dislocation. None of the anatomical factors studied was related to the occurrence of anterior cruciate ligament injury.
