- Posterolateral reconstruction combined with one-stage tibial valgus osteotomy: Technical considerations and functional results(2019) HELITO, Camilo Partezani; SOBRADO, Marcel Faraco; GIGLIO, Pedro Nogueira; BONADIO, Marcelo Batista; DEMANGE, Marco Kawamura; PECORA, Jose Ricardo; CAMANHO, Gilberto Luis; ANGELINI, Fabio JansonBackground: To report the functional outcomes and complications from reconstructing the knee posterolateral complex (PLC), associated with one-stage opening-wedge tibial valgus osteotomy, and discuss the technical feasibility of this procedure. Methods: Five patients with chronic PLC injuries and varus deviation of the mechanical axis, associated with central pivot injuries or not, underwent medial opening-wedge high tibial osteotomy combined with PLC reconstruction. The lateral collateral ligament, popliteal tendon, and popliteofibular ligament were reconstructed using a single femoral tunnel. Patients were assessed on physical examination, range-of-motion and functional scales, and radiographs. The International Knee Documentation Committee (IKDC) score, Lysholm score, and Knee Injury and Osteoarthritis Outcome score (KOOS) were determined. Results: Five patients were evaluated: four presented with central pivot injury, and one had an isolated PLC injury. The mean time between injury and surgery was 40 +/- 6.5 months (+/- is indicating standard deviation value). Four patients had minimal residual instability on physical examination, with a lateral opening at varus stress of +/- 3 + at 30 degrees flexion. The means of the IKDC score, Lysholm score, and KOOS were 67.8 +/- 9.2, 83.0 +/- 9.3, and 79.2 +/- 5.9, respectively. All patients showed satisfactory consolidation of osteotomy in 2.6 +/- 0.9 months. Conclusions: The results of this series indicate that one-stage PLC ligament reconstruction associated with medial opening-wedge valgus osteotomy is feasible and shows satisfactory functional results with a low rate of complications. A one-stage procedure might be indicated for young patients with high functionality and more pronounced posterolateral instabilities.
- Screw loosening and iliotibial band friction after posterolateral corner reconstruction(2014) HELITO, Camilo Partezani; BONADIO, Marcelo Batista; DEMANGE, Marco Kawamura; ALBUQUERQUE, Roberto Freire da Mota e; PECORA, Jose Ricardo; CAMANHO, Gilberto Luis; ANGELINI, Fabio JansonBackground: Many reconstruction techniques have already been developed for treating posterolateral corner (PLC) injuries, with still no consensus regarding what would be the best option. Some techniques use non-bone tunnel fixation, attaching the graft to the femur using a cortical screw with toothed washer. The main objective of the present study is to evaluate complications related to fixation performed by a screw and toothed washer technique. Methods: A prospective study with surgical reconstruction of the PLC structures of the knee between January 2008 and December 2009 was performed. PLC reconstruction included reconstruction of the lateral collateral ligament, popliteofibular ligament and popliteal muscle tendon. Fixation of the grafts in the femur was achieved by means of a 4.5 mm screw with a toothed washer. The assessments were done using the following methods: objective IKDC, subjective IKDC, Lysholm and Tegner. Radiographic evaluations were performed immediately after the operation, at 3, 6 and 12 months after surgery, and yearly thereafter. Complications were documented. Results: The mean subjective IKDC score after the operation was 69.2; Lysholm scale was 80.7. Two patients presented failure of reconstructions of the PLC. In the radiographic evaluations, signs of loosening of the screw with toothed washer in the femur were observed in eight cases (66.6%). Six patients (50%) complained of lateral pain after the operation. Conclusion: The technique of femoral fixation was shown to be efficient in restoration of stability. However there was a high rate of complications secondary to implant, such as loosening of the screws and iliotibial tract friction.
- Plateau-patella angle: An option for the evaluation of patellar height in patients with patellar instability(2017) BONADIO, Marcelo Batista; HELITO, Camilo Partezani; TORRES, Julio Augusto do Prado; GOBBI, Riccardo Gomes; PECORA, Jose Ricardo; CAMANHO, Gilberto Luis; DEMANGE, Marco KawamuraBackground: Patellar instability is a debilitating disease. An important factor related to recurrent dislocation is patellar height. A new method of patellar height measurement, the plateau-patella angle (PPA), was proposed in 2011. However, to date, there is no study evaluating the use of this method in patients with patellar instability. The aim of this study was to evaluate the PPA in patients with recurrent patellar dislocation. Methods: This was a retrospective evaluation of the radiographs of 78 knees with patellar instability. Patellar height was measured using the Insall-Salvati (VS), Caton-Deschamps (C/D) and Blackburne-Peel (B/P) indices and the PPA. The qualitative and quantitative correlations between the various methods and between observers were calculated. Results: The PPA had a Pearson correlation of 0.76 (P <0.001) with the I/S index, 0.78 (P < 0.001) with the C/D index and 0.90 (P < 0.001) with the B/P index. In the qualitative correlation using the Spearman coefficient, the PPA had a correlation of 0.52 (P < 0.001) with the I/S index, 0.72 (P < 0.001) with the C/D index and 0.70 (P < 0.001) with the B/P index. The correlations between the conventional methods were as follows: 0.57 (P < 0.001) between the I/S and C/D indices; 0.61 (P < 0.001) between the I/S and B/P indices; and 0.73 (P < 0.001) between the C/D and B/P indices. Conclusion: The determination of the PPA is a reproducible method that is consistent with the methods currently used to measure patellar height in patients with recurrent patellar dislocation.
