The genu valgum is one of the anomalies of the lower extremities in the coronal plane (knocked knees). Children might be vulnerable to it as well. It may also be hereditary, with females being more likely to develop it. A 14-year-old female patient had severe genu valgum anomalies of the bilateral lower extremities. The patient is in pain, unable to stand, and sit on the ground. On the numerical pain rating scale (NPRS), the level of pain was rated as 8/10 while activity and 5/10 during rest. The patient received physiotherapy treatment for a total of six weeks, which included exercises, electrotherapy, and gait training. As a result, the patient experienced a reduction in pain, which was rated 2/10 while activity and 1/10 during rest, and an improvement in range of motion, and functional activities. Correcting the gait, enhancing the quality of life, and restoring functional ability are all significantly impacted by physiotherapy. Based on the current case study, conventional physical therapy improved functional goals gradually and significantly, which in turn potentially aided in a successful recovery.
