Summary: The group of partial resection of Hoffa’s fat pad has comparable patient satisfaction and functional outcomes compared with the group of total resection at short-term follow-up.
Abstract:
Background
No reported study has compared the clinical outcomes of partial resection and that of total resection against Hoffa’s disease
Introduction
This study compared the clinical outcomes of partial resection and that of total resection of Hoffa’s fat pad
Study Design: prospective comparative study
Methods
59 patients who were confirmed and treated arthroscopically following by diagnosed of Hoffa’s fat pad impingement(= Hoffa’s disease) by physical exam, MR image and steroid injection study in our hospital were included. We set prospectively that the patients with Hoffa’s fat pad impingement in left knee were treated by partial resection of Hoffa’s fat pad and classified as group A and the patients with impingement in right knee were treated by total resection and classified as group B. Group A has 33 patients and group B has 27 patients. Clinical outcomes were evaluated a minimum 1 years (mean 24.89 months; range, 12–36) postoperatively using the VAS, IKDC 2000 subjective knee score, Lysholm scores.
Results
At the final follow-up, the average VAS, IKDC, Lysholm scores improved significantly, to 1.97, 85.99, and 91.27 respectively in the group A and to 2.38, 87.26, and 91.42 respectively in the group B. The VAS, IKDC, Lysholm scores improved in both groups postoperatively (all P < 0.001); however, there was no significant difference between the two groups at final follow-up (P = 0.586, 0.120, and 0.306, respectively).
Conclusions
The group of partial resection of Hoffa’s fat pad has comparable patient satisfaction and functional outcomes compared with the group of total resection at short-term follow-up.
