Background: Active rehabilitation has an important role in the management of patellofemoral pain syndrome (PFPS). Although some studies have shown the benefit of hip-muscle strengthening, the effect of combining hip-muscle stretching with strengthening has not yet been defined. Purpose: To evaluate the effect of combined strengthening of the hip external rotators and abductors and stretching of the hip internal rotators on pain and function in patients with PFPS. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: A total of 109 patients with PFPS (75 female and 34 male; mean age, 31.6 ± 10.8 years) were first randomly assigned to protocol A (n = 67) of the A-B arm (AB group; standard rehabilitation) or protocol B (n = 42) of the B-A arm (BA group; standard rehabilitation with strengthening of the hip external rotators and abductors and stretching of the hip internal rotators). Each protocol consisted of 3 sessions a week for 4 weeks. After a washout period, corresponding to a symptom-free period, rehabilitation programs were crossed over. A visual analog scale (VAS) evaluating perceived pain, the Functional Index Questionnaire (FIQ), and the Kujala score were administered at baseline, the end of each rehabilitation protocol, and 12 weeks after the completion of the second protocol for each group. Results: Until the final follow-up, VAS, FIQ, and Kujala scores were significantly improved in both the A-B and B-A arms ( P < .05 for all). Compared with protocol A, protocol B provided significant improvement in terms of pain and function in both the BA (VAS and Kujala; P < .001) and AB (VAS and Kujala; P < .001) groups. Conclusion: Combined strengthening of the hip abductors and external rotators with stretching of the hip internal rotators provided better outcomes, which were maintained for at least 12 weeks, in terms of pain and function in patients with PFPS.

Abstract Context: Very few authors have investigated the relationship between hip-abductor muscle strength and frontal-plane knee mechanics during running. Objective: To investigate this relationship using a 3-week hip-abductor muscle-strengthening program to identify changes in strength, pain, and biomechanics in runners with patellofemoral pain syndrome (PFPS). Design: Cohort study. Setting: University-based clinical research laboratory. Patients or Other Participants: Fifteen individuals (5 men, 10 women) with PFPS and 10 individuals without PFPS (4 men, 6 women) participated. Intervention(s): The patients with PFPS completed a 3-week hip-abductor strengthening protocol; control participants did not. Main Outcome Measure(s): The dependent variables of interest were maximal isometric hip-abductor muscle strength, 2-dimensional peak knee genu valgum angle, and stride-to-stride knee-joint variability. All measures were recorded at baseline and 3 weeks later. Between-groups differences were compared using repeated-measures analyses of variance. Results: At baseline, the PFPS group exhibited reduced strength, no difference in peak genu valgum angle, and increased stride-to-stride knee-joint variability compared with the control group. After the 3-week protocol, the PFPS group demonstrated increased strength, less pain, no change in peak genu valgum angle, and reduced stride-to-stride knee-joint variability compared with baseline. Conclusions: A 3-week hip-abductor muscle-strengthening protocol was effective in increasing muscle strength and decreasing pain and stride-to-stride knee-joint variability in individuals with PFPS. However, concomitant changes in peak knee genu valgum angle were not observed.

Patellofemoral Pain Syndrome (PFPS) is pain in the front knee joint due to muscle imbalance especially weakness of the vastus medialis oblique muscle and the stiffness of the hamstrings leads to a patellar position shift to the lateral side (maltracking). Selective VMO exercise is one of conservative therapy to restore VMO muscle strength. The purpose of this study was to determine the effect of Selective Vastus Medial Obliquus Exercise on decreasing the degree of pain and attainment of  Range Of Motion patients with PateloFemoral Pain Syndrome. The method of this research used pre experimental design with one group pre-post test design without group control. The number of samples is 13 respondents PFPS who meet the criteria of inclusion and exclusion with purposive sampling. Data were obtained from observation of difference of Visual Analogue Scale (VAS) and ROM (universal goniometer) pain score before (pre-test) and after (post-test) doing exercise therapy. All data were analyzed statistic using Wilcoxon Signed Ranks Test with significance value (p <0,05).. The result of this research shows that there is selective effect of Vastus Medial Obliquus Exercise on the decrease of pain degree with p value = 0.001 (α = 0,05) and attainment of Range Of Motion patient with flexy value p value = 0,039 (α = 0,05) p value = 0.001 (α = 0.05). Decreasing the degree of pain post selective VMO exercise and attainment full ROM showed strengthening of VMO muscle so patella returned to optimal tracking. Suggestion: Measurement of VMO and VL muscle strength can be done with EMG.

Purpose: Patellofemoral Pain Syndrome (PFPS) is among the most prevalent complaints observed in healthcare clinics. This group of patients encounters Pelvic Drop (PD) and Dynamic Knee Valgus (DNV); its’ causes have been reported as pain and decreased muscle strength. The current study aimed to explore the effects of a 12-week Sensorimotor Exercise (SME) on pain, strength, PD, and DNV in males with PFPS. Methods: This randomized double-blind clinical trial involved 32 patients with PFPS. The study samples were randomly divided into the experimental (n=16) and control (n=16) groups. To assess pain, the Visual Analogue Scale (VAS) was used. Moreover, quadriceps muscle strength was measured by the hip abductor hand dynamometer. To analyze PD and DNV, camera and Kinova software were used during stairs descent. The experimental group performed 12 weeks of SME for 3 one-hour weekly sessions. However, the control group received no therapeutic intervention during this time. The obtained data were analyzed in SPSS using Analysis of Covariance (ANCOVA).  Results: The data analysis results suggested that pain significantly reduced in the experimental group, compared to the control group, after twelve weeks of SME (P<0.001). Besides, quadriceps muscle strength (P<0.002) and hip abductor muscle strength (P<0.001) improved, and PD angle (P<0.002) and DNV (P<0.003) were reduced. Conclusion: SME reduced pain and facilitated the frequency and time of muscle activation. It also increased the strength of the gluteus medius muscle as the main stabilizer of the pelvis chain and led to a reduction in PD and DNV. Thus, SME could be used as a comprehensive protocol treatment to improve various disorders in patients with PFPS.
