BOSTON — Results presented at the Arthroscopy Association of North America Annual Meeting showed at long-term follow-up, lesion size at index microfracture had no effect on function, activity level or patient satisfaction.
“The results were the same regardless of lesion anatomic location within the knee,” William G. Rodkey, DVM, said in his presentation. “This confirmed our hypothesis that outcomes were unaffected by index lesion size if proper technique and rehabilitation protocols are used. Therefore, lesion size should not be a limitation for use of microfracture procedure when done correctly at least up to 600 mm2.”
Rodkey and his colleagues grouped 531 knees with contained focal chondral lesions treated with microfracture according to the following lesion sizes: 200 mm2 or smaller (group 1); 200 mm2 to 400 mm2 (group 2); and 400 mm2 to 600 mm2 (group 3). Lesions were also separated by anatomic location in either the tibiofemoral or patellofemoral areas, according to Rodkey. Researchers measured lesion size and collected SF-12 physical component scores, WOMAC scores, Lysholm function score, Tegner activity level and patient satisfaction with outcomes.
At 10-year to 22-year follow-up, results showed all scores were almost identical for tibiofemoral lesions regardless of lesion size.
“There was no significant difference in outcomes regardless of the index lesion size for the tibiofemoral lesions,” Rodkey said.
Similarly, Rodkey noted outcomes for patellofemoral lesions were almost identical across lesion group size, with no significant difference in outcomes regardless of index lesion size. – by Casey Tingle
