High lateral portal for sparing the infrapatellar fat-pad during ACL reconstruction.

ABSTRACT

During arthroscopic ACL reconstruction, intra-articular visualization can be compromised by the interposition of the infrapatellar fat pad (IPFP) between the scope and the notch. In this technical note, we describe our technique of using lateral higher arthroscopic portal, starting arthroscopy with the resection of the ligamentum mucosum and performing the tibial tunnel in 40° of knee flexion to optimise the intra-articular view without IPFP debridement. This technique was performed in 112 consecutive arthroscopic ACL reconstructions and compared to that in the previous 112 cases in which a conventional method was used. The use of this technique was associated with a shorter operative time and no increase in the difficulty in performing associated meniscal procedures.
