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

Purpose and Hypothesis: Trigger points (TrP) is one of the most common causes of musculoskeletal disorders. Myofascial trigger point in vastus lateralis muscle has been reported high prevalently in subjects with patellofemoral pain syndrome. The purpose of this study was to investigate the effects of dry needling and kinesio tape on trigger point in vastus lateralis muscle. Randomized controlled trial designed to investigate the effect of Dry Needling (DN) and Kinesio Taping (KT) on pain intensity and knee disability after session’s treatment in individuals with trigger point (TrP) in Vastus Lateralis (VL) muscle. Methods: 30 subjects with TrP in the VL muscle participated in this study. Subjects were randomly assigned to a DN group ([Formula: see text]) or KT group ([Formula: see text]). Results: Statistical analysis (paired [Formula: see text]-test) revealed a significant improvement in VAS during activity and KOOS scores after three sessions treatment in both of groups compared with before treatment ([Formula: see text]). But PPT was not increased after one week treatment. VAS using an algometer was decreased only at DN group ([Formula: see text]). The results showed no significant changes in variables immediately after intervention. The ANCOVA revealed no significant differences between the DN and KT groups on the post-measurement VAS during activity, VAS using an algometer, PPT, KOOS scores ([Formula: see text]). Conclusion: DN and KT produce an improvement in pain intensity and knee disability and may be prescribed for PFPS subjects with TrP in VL muscle especially when pain relief is the goal of the treatment.
