Abstrakt:	Unlabelled: To evaluate whether, after total knee arthroplasty, there is any correlation between patellar height and range of motion (ROM) achieved by patients six months after the operation. Methods: Forty-five patients who underwent total knee arthroplasty were assessed at least 12 months after the operation (total of 54 knees). The maximum and minimum ROM of all the knees was recorded under fluoroscopy, along with patellar height according to the Blackburne and Peel ratio. Two possible correlations were evaluated: patellar height and ROM; and patellar height and ROM variation from before to after the operation. Results: A correlation was found between patellar height and postoperative ROM (p = 0.04). There was no correlation between patellar height and ROM variation (p = 0.182). Conclusion: After total knee arthroplasty, the lower the patella is, the worse the ROM is.
