Introduction:
Early post-operative x-rays are often taken in total knee replacements (TKRs). Patient mobilisation may be delayed until these x-rays are obtained and this may prolong discharge. The aim of this study was to assess the value of such early x-rays and whether they influenced the early post-operative management of these patients.
Methods:
A total of 624 consecutive TKRs performed at the Blackpool Victoria Hospital over a 34-month period were evaluated. Plain anteroposterior and lateral x-rays were examined.
Results:
Two patients were found to have significant abnormalities: an undisplaced periprosthetic tibial fracture and a partial inferior pole patellar avulsion. Neither of these required further treatment or influenced mobility. No other complications were noted that changed routine post-operative management.
Conclusions:
These results question the need for immediate x-rays in primary TKRs.
