Implication

Randomized trial reveals a 0.5-degree tibial angle difference in knee replacement patients, indicating comparable radiological outcomes between intramedullary and extramedullary guides.

Key Points

To critically evaluate radiological alignment outcomes and methodological limitations in a trial comparing extramedullary and intramedullary tibial alignment guides during total knee replacement.
Critique of a prospective randomized trial comparing extramedullary versus intramedullary alignment guides in 135 recruited total knee arthroplasty patients.
Evaluation of post-operative tibial component angles, radiographic standardization, and attrition bias from missing imaging data (35 of 135 patients).
The mean difference in tibial component angle between the extramedullary and intramedullary groups was 0.5˚.
Only four patients (two in each group) fell outside the acceptable alignment range of 90 ± 4˚.
Acceptable radiographs were unobtained in 35 of 135 recruited patients without reported group distribution, limiting definitive claims of intramedullary superiority.
