Introduction: Navigated TKA (Total Knee Arthroplasty) has heightened awareness of mal-alignment in conventional TKA, as well as providing an accurate means of measuring alignment intra-operatively. Debate as to the importance and significance of alignment versus knee balance continues.
Aim: To assess cutting error, and examine the hypothesises:
• ‘Slotted osteotomies are more accurate than non-slotted’
• ‘Second pass of the saw blade improves the accuracy of osteotomies’
Method: Three pairs of fresh frozen human knees were prepared, exposed, and positioned as for primary TKA. Standard cutting guides were used in conjunction with a clinical navigation system, and the error (difference between the achieved resection, and the planned resection) in each osteotomy wa..
