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