Dual–Posteromedial Portal Technique for Complex Arthroscopy in the Posterior Knee

Abstract

Arthroscopy in the posterior knee continues to improve as new techniques arise. Traditionally, posterior techniques included posteromedial and posterolateral portals. Although frequently used, these techniques do have some limitations. We propose the use of dual posteromedial portals for complex arthroscopy cases to improve access and instrumentation in the posterior knee. Applications include, but are not limited to, resection of tumors or masses in the posterior knee, meniscal posterior horn repair, ramp lesion repair, repair of posterior cruciate ligament avulsions, and use as accessory portals for arthroscopic posterior cruciate ligament reconstruction. We describe a technique for establishing dual posteromedial portals for complex arthroscopy in the posterior knee, specifically in relation to a case of a posterior knee mass biopsy and resection.
