    Footwear makes our feet weak even if we are active. So there is a foot strength/ rest of body strength imbalance, even before an exercise program is begun.

    Now we start an athletic training program but still with splinted feet. The bodies muscles get stronger but not the foot vital muscles, and this may lead to injury. A period of rest allows the injury to recover but also allows the trained muscles to get a bit weaker again. The feet are initially under less strain as training resumes so all is ok for a while .

    But: The other muscles get stronger again and once more the foot cant cope with the demands being placed on it.

    And round and round we go. The solution..........

    So a runner, complaining of knee pain, walks in to see a physio .
    The physio says " yes you have PFP " and gives the patient exercises to strengthen the quads , hamstrings, and glutes but does nothing about the probably gross weaknesses in the man's feet .
    So now the strength imbalances between the pts lower limb and foot become even greater and the PFP may even get worse.

    Recently a treatment regime called peace and love was suggested by a group of physios. This should work, at least short term , as it allows the leg muscles to power down and prevents the capacity of the feet being exceeded .

    Might be better though, simply strengthening the pathetically weak feet which most habitually shod people have.

    Here is the abstract from another recent ( 2022) study on PFPS ( knee pain ).

    Conclusions: Our study is a novel approach to the potential impact of foot interventions on patellofemoral pain. Foot intervention including TJM and FCS is effective for pain control and function improvement in individuals with PFPS.

    Abstract

    Background: Patellofemoral pain syndrome (PFPS) is defined as pain around the patella while performing activities such as squats, running, and climbing steps. One of the inherent risk factors for PFPS is an excessively pronated foot posture. The aim of this study was to investigate the effect of foot intervention, talonavicular joint mobilization (TJM) and foot core strengthening (FCS), on PFPS.
    Methods: Forty-eight patients with PFPS (mean age, 21.96 ± 2.34 years; BMI, 22.77 ± 2.95 kg/m2) were enrolled in the study. Participants were randomly assigned in a 1:1:1 ratio to three groups, and received 12 sessions of TJM, FCS, and blended intervention at university laboratory for 4 weeks. The primary outcomes were pain while the secondary outcomes were lower extremity function, valgus knee, foot posture, and muscle activity ratio measured at baseline, after 12 sessions, and at the 4-week follow-up.
    Results: The two-way repeated-measures ANOVA revealed significant interactions in all groups (p < 0.05). TJM reduced pain more than the FCS at post-test (mean difference, - 0.938; 95% Confidence interval [CI], - 1.664 to - 0.211; p < 0.05), and blended intervention improved lower extremity function (mean difference, 6.250; 95% CI, 1.265 to 11.235; p < 0.05) and valgus knee (mean difference, - 11.019; 95% CI, - 17.007 to - 5.031; p < 0.05) more than the TJM at 4 weeks follow-up. TJM was more effective in post-test (mean difference, - 1.250; 95% CI, - 2.195 to - 0.305; p < 0.05), and TJM (mean difference, - 1.563; 95% CI, - 2.640 to - 0.485; p < 0.05) and blended intervention (mean difference, - 1.500; 95% CI, - 2.578 to - 0.422; p < 0.05) were more effective in foot posture than the FCS in 4 weeks follow-up. Blended intervention displayed greater improvement in muscle activity than the TJM (mean difference, 0.284; 95% CI, 0.069 to 0.500; p < 0.05) and the FCS (mean difference, 0.265; 95% CI, 0.050 to 0.481; p < 0.05) at 4 weeks follow-up.
    Conclusions: Our study is a novel approach to the potential impact of foot interventions on patellofemoral pain. Foot intervention including TJM and FCS is effective for pain control and function improvement in individuals with PFPS.

    Note ; Although it can be argued that increased quad/glut strength can help reduce peak forces in leg structures during some parts of the running cycle, it should be noted that peak stain in the plantar fascia occurs during push off as the heel clears the ground . Extra power at this point will presumably lead to increased load in the PF.
