The effect of drilling angle on intra-articular tibial tunnel dimensions: Technical considerations

J Knee Surg. 2007 Oct;20(4):289-91. doi: 10.1055/s-0030-1248060.


Tibial tunnel variations are not solely dependent on the location of guide pin placement. There may be significant changes in intra-articular tunnel position and dimensions based on the drilling angle despite ideal pin position. Using a simple mathematical model, this effect was quantified and its clinical implications are discussed.
