OBJECTIVE: : To determine
the effect on pain, function, and ultrasonographic findings of
ultrasonography-guided Baker's cyst aspiration followed by corticosteroid
injection in a group of patients with Baker's cyst secondary to knee
osteoarthritis. DESIGN: : Prospective observational study. RESULTS: : Twenty-six
subjects participated in this study. Clinical and instrumental evaluations were
performed at baseline (T0), 1 wk (T1), and 4 wks (T2) after procedure. Mean
Visual Analog Scale scores significantly dropped after the procedure (T0 = 6.2
[1.2]; T1 = 4.48 [1.5]; T2 = 4.32 [1.3]; T0 vs. T1 and P < 0.0001). A significant
difference between preprocedure and postprocedure Western Ontario and McMaster
Universities scores was found for pain (P < 0.0001) but not for joint stiffness
(P = 0.7239) and disability
(P = 0.6318). Ultrasonographic evaluation showed a
significant reduction for both axial (P = 0.006) and sagittal
(P = 0.01) areas of
Baker's cyst, but no correlation was found between pain relief and Baker's cyst
volume reduction. CONCLUSIONS: : Cyst aspiration with corticosteroid injection
give pain relief and cyst volume reduction in patients with Baker's cyst and
concomitant knee osteoarthritis. However, when compared with current literature,
our results are similar to those obtained with intra-articular knee
corticosteroid injection.
