Posterior Arthroscopic Tibiotalar Arthrodesis: Anatomic Feasibility Study.

Anterior arthroscopic tibiotalar arthrodesis has been well codified. A posterior approach with the patient in prone position is indicated when the anterior approach is precluded by soft tissue issues or for a 1-step procedure associated with posterior subtalar fusion. In an anatomic study, we assessed the feasibility of posterior arthroscopic tibiotalar fusion and sought to determine the arthroscopy entry points, mortise cartilage freshening quality, and risk of osseous, tendinous, vascular, and neural complications.

Does patellofemoral congruence following total knee arthroplasty correlate with pain or function? Intraoperative arthroscopic assessment of 30 cases.

Background: Anterior knee pain (AKP) is observed in total knee arthroplasty (TKA) both with and without patellar resurfacing, and neither patellar denervation nor secondary resurfacing are effective for treating the symptoms. The exact causes for pain remain unclear, though abnormal patellofemoral forces due to patellar malalignment or inadequate implant design can play an important role. The purpose of this study was to arthroscopically evaluate patellofemoral congruence after wound closure following TKA without patellar resurfacing and correlate it to patellar morphology and postoperative pain and function.

Anatomic Feasibility Study of Posterior Arthroscopic Tibiotalar Arthrodesis.

Background: Operative indications for an anterior arthroscopic tibiotalar arthrodesis are well defined. A posterior approach with the patient in a prone position may be indicated when the anterior approach is precluded by the soft tissue condition or for a 1-step procedure associated with posterior approach subtalar fusion.

Methods: An anatomic study assessed the feasibility of posterior arthroscopic tibiotalar fusion and sought to determine arthroscopy entry points, mortise cartilage freshening quality, and the risk of osseous, tendinous, vascular, and neural complications.
