Anatomic Posterolateral Knee Reconstructions Require a Popliteofibular Ligament Reconstruction Through a Tibial Tunnel

2010

Background: No biomechanical study has been performed analyzing the merits of reconstructing the popliteofibular ligament (PFL) through a tibial tunnel with an anatomic reconstruction of the posterolateral knee. Hypothesis: There is no difference in an anatomic posterolateral knee reconstruction with or without a PFL reconstruction placed through a tibial tunnel in restoring knee motion to the intact, uninjured state, and the knee is not overconstrained with this reconstruction. Study Design: Controlled laboratory study. Methods: Eight paired knees were tested in the intact state and then sectioned to simulate a grade III posterolateral knee injury. The reconstruction for the first paired …

Mid-term results of isolated posterolateral corner reconstruction

2009

Isolated posterolateral corner (PLC) tears are relatively rare events. Various surgical techniques to treat posterolateral knee instability have been described; because surgical results are very much linked to cruciate reconstructions to date it is difficult to define whether one surgical procedure has better prognosis than another. The goal of this study is to determine the clinical outcome of PLC reconstruction following fibular-based technique. MATERIALS AND METHODS: We retrospectively evaluated a case series of patients who had received isolated PLC reconstruction between March 2005 and January 2007. 12 patients were surgically treated for isolated injuries and 10 patients were availabl…

The goal of this study is to determine the clinical outcome of PLC reconstruction following fibular-based technique.

Ten patients were surgically treated for isolated injuries and were availabl…

Proximal Tibiofibular Joint Reconstruction With Autogenous Semitendinosus Tendon Graft

2013

Isolated and chronic anterolateral instability of the proximal tibiofibular joint (TFJ) is an uncommon condition, generally linked to an unrecognized or unhealed dislocation of the TFJ. Clinically, abnormal anterior movement of the head of the fibula is detected. In acute injuries conservative management should be preferred, whereas surgical treatment have been advocated in patients with chronic TFJ instability. Authors describe a new surgical reconstruction technique for chronic instability of the proximal TFJ using an autogenous semitendinosus tendon. The graft is passed through fibular and tibia tunnels and fixed with 2 interference screws. The tibial tunnel is reamed from the posterolat…

Anatomia e biomeccanica del posterolateral corner del ginocchio

2009

“Dark side of the knee”: letteralmente, lato oscuro del ginocchio. Questa definizione ben si adatta alle strutture postero-esterne del ginocchio. Questa regione anatomica negli ultimi anni ha saputo attirare l’attenzione di ricercatori e studiosi, per molto e forse troppo tempo focalizzata sullo studio del legamento crociato anteriore. Comunque, l’analisi dei risultati e degli insuccessi della chirurgia ricostruttiva del legamento crociato anteriore ha dato uno slancio fondamentale per comprendere ancor di più la complessa biomeccanica del ginocchio e le lesioni associate a rottura dei legamenti del pivot centrale come quelle postero-laterali. In questa rivisitazione della letteratura ci si…

Update nella diagnosi delle lesioni posterolaterali del ginocchio

2011

Nell’ultimo decennio sono stati fatti grossi passi in avanti nella chirurgia ricostruttiva legamentosa del ginocchio. La ricerca dei fattori che possono condurre al fallimento della ricostruzione del legamento crociato anteriore (LCA) ha aperto la strada allo studio di diverse strutture anatomiche come quelle posterolaterali, rimaste nella penombra per troppo tempo. Nonostante l’estrema variabilità delle strutture anatomiche posterolaterali, studi di dissezione anatomica hanno permesso di osservare come il legamento collaterale laterale (LCL), il popliteo ed il legamento popliteo-fibulare (LPF) risultino essere quasi costantemente presenti. Sono state inoltre chiarite le specifiche funzioni…
