Abstract:
Ischaemic complications of total knee arthroplasty (TKA) are unusual and tend to occur in patients with peripheral vascular disease (PVD). A prospective study was undertaken to investigate the effect of TKA on blood flow in patients without clinical evidence of PVD. Ankle brachial index (ABI) did not alter post-operatively and no changes in arterial waveforms were found. Unless there is clinical evidence of PVD, TKA under tourniquet control is therefore very unlikely to cause ischaemic complications.
