The Use of the 70° Arthroscope for Anatomic Femoral and Tibial Tunnel Placement and Tunnel Viewing in Anterior Cruciate Ligament Reconstruction Thomas A. Bucher, M.B.B.S., F.R.C.S.(Tr&Orth), M.Sc., Soulat Naim, M.S.(Orth), M.Ch.(Orth), F.R.CS.(Tr&Orth), Vipul Mandalia, M.B.B.S., F.R.C.S., F.R.C.S.(Tr&Orth) Arthroscopy Techniques Volume 3, Issue 1, Pages e79-e81 (February 2014) DOI: /j.eats Copyright © Terms and Conditions

Fig 1 Stryker camera covered with Clinicon quick-change camera drape (left) and Olympus 30° and 70° arthroscopes (right). This allows rapid changing between the 30° and 70° arthroscopes and the need for only 1 camera. Arthroscopy Techniques 2014 3, e79-e81DOI: ( /j.eats ) Copyright © Terms and Conditions

Fig 2 (A) Femoral footprint view with 30° arthroscope from AL portal showing inadequate visualization of femoral footprint. (B) Femoral footprint view with 30° arthroscope from anteromedial portal. (C) Femoral footprint view with 70° arthroscope from AL portal. Excellent visualization of the femoral footprint is achieved.

Fig 3 (A) Bird’s-eye view of the tibial footprint through the 70° arthroscope from the AL portal, showing the relation of the PBAHLM (arrow) with the center of the tibial stump (marked with diathermy). (B) View of the same patient using the 30° arthroscope from the AL portal, which does not show a clear relation between the PBAHLM and the tibial stump because of the more oblique view obtained with the 30° arthroscope.

Fig 4 (A) View of femoral tunnel with 70° arthroscope from AL portal. (B) Tibial tunnel viewed through 70° arthroscope from AL portal. (C) Tibial tunnel view in revision ACLR with 70° arthroscope through AL portal. One should note the ability to inspect the entire tunnel, which is particularly important if using an interference screw as femoral fixation and is also useful in revision ACLR.
