Dose atrophy of vastus medialis obliquus and vastus lateralis exist in patients with patellofemoral pain syndrome

Abstract Background Whether vastus medialis obliquus atrophy exists in patients with patellofemoral pain syndrome and whether the amount of differs between lateralis muscles remain unknown. Materials From June 2016 to March 2019, 61 were retrospectively included study group, an age-, sex-, body mass index-matched cohort normal knees was randomly selected as control group. All enrolled subjects had undergone CT scans supine position. The cross-sectional areas muscle sections 0, 5, 10, 15, 20 mm above upper pole patella measured, obliquus/vastus area ratio evaluated. Results In that significantly smaller than respective group ( P < 0.05). at (the section 0 patella) corresponding No significant difference noted two groups > Conclusion syndrome, existed 0–20 patella, compared controls, more evident patella. These findings support rationale for use general quadriceps exercise combined strengthening part rehabilitation programme syndrome.
