The health crisis caused by COVID-19 has had a huge impact on the provision of physiotherapists’ services during the pandemic. Patellofemoral pain syndrome (PFPS) is a major health problem and one of the most common causes of pain in the front of the knee in outpatients. The objective was to evaluate the effectiveness of a therapeutic physical exercise (TPE) program supervised by a physiotherapist using telematic channels in reducing pain and disability in a sample of 54 patients with PFPS in the Physiotherapy Service of the San José de la Rinconada Health Center (Seville). Subjects were evaluated pre- and post-intervention (4 weeks—12 treatment sessions). An analysis was made of perceived pain—using the visual analog scale (VAS) and the DN4 neuropathic pain questionnaire—and functional balance—through the Kujala Score test and the Lower Extremity Functional Scale. The supervised TPE program in patients with PFPS produced a reduction in pain: VAS F(1, 52) = 8.68 (p = 0.005) η(2) = 0.14 and DN4: F(1, 52) = 69.94 (p = 0.000) η(2) = 0.57; and in Lower Extremity Functional Scale (LEFS) disability: F(1, 52) = 19.1 (p = 0.000) η(2) = 0.27 and KUJALA: F(1, 52) = 60.28 (p = 0.000) η(2) = 0.54, which was statistically significant (p = 0.000 for p < 0.05). Hence, the TPE program presented was effective in reducing pain and disability in patients with PFPS.
