I have often found it difficult to get to the desired spot in the femur for drilling holes in ACL/PCL reconstructions. Invariably the Beath needle would feel as if it slips a few millimeters when I start to rotate it.
Here's how I systematically execute this challenge now to eliminate drill tracking errors during arthroscopic stabilization sequences.
The Proposed Technique Strategy:
Once the graft has been prepared and I know its thickness and the desired tunnel size in the femur, I would use the relevant size reamer as a sleeve and impact it lightly at the desired tunnel spot. Through the reamer, the Beath needle is safely introduced and drilled through the femoral condyles.
Reaming proceeds routinely thereafter. Utilizing this modified approach ensures that the final tunnel configuration aligns precisely where intended without edge-slippage complications.
