To evaluate the response of symptomatic degenerative tears of the posterior horn of the medial meniscus to guided intra-articular knee steroid/bupivacaine injection and to correlate clinical outcomes with preprocedural findings at magnetic resonance imaging (MRI). Arthroscopy to remove such cysts is the conclusion. Knee. Preprocedural MRI findings were correlated with duration of symptoms, clinical response to injection (recorded as complete, partial or no response) and duration of response to injection. Knees with mucoid ACL degeneration had significantly more meniscal damage compared to controls (mean WORMS of medial meniscus of 2.7 vs. 2.1, P=0.033; and mean WORMS of lateral meniscus of 1.1 vs 0.6, P=0.012).
