[Purpose] This study aimed to determine the relationship between preoperative and
discharge assessments in patients undergoing around-the-knee osteotomy. [Participants and
Methods] We enrolled patients admitted to our hospital who underwent around-the-knee
osteotomy. We measured knee joint range of motion, pain numeric rating scale, pain
catastrophizing scale, hospital anxiety and depression scale, and 10-m walk time were
measured preoperatively and before discharge. Pre-post comparisons and correlation testing
were performed. [Results] A total of 18 patients were analyzed. Resting and exercise pain
numeric rating scale, knee flexion and extension range of motion, and pain catastrophizing
scale were significantly better during discharge. A significant correlation was observed
between the preoperative pain catastrophizing scale total score and 10-m walking time,
knee flexion and extension range of motion, pain catastrophizing scale total score, and
hospital anxiety and depression scale-depression subscale preoperatively. [Conclusion]
Appropriate postoperative rehabilitation after around-the-knee osteotomy improved physical
function and cognitive/psychological evaluation at discharge. The correlation between the
preoperative pain catastrophizing scale total score and 10-m walking time at discharge
suggests that the prolonged walking pain that occurred preoperatively may have affected
the cognitive and psychological evaluation of pain.
