Leg and knee injuries, often resulting from sports-related activities, falls, or trauma, present with symptoms such as pain, swelling, and restricted mobility. Common conditions include ligament sprains, meniscus tears, or fractures, impacting daily activities and stability. Emergency signs like severe pain, visible deformity, or the inability to bear weight require immediate medical attention. Diagnosis involves a thorough physical examination and may include imaging studies such as X-rays or MRI to assess the severity of the injury. Treatment approaches encompass rest, ice, compression, and elevation (R.I.C.E.), along with physiotherapy to enhance strength and flexibility. In severe cases, surgical intervention may be considered, followed by a structured rehabilitation program to optimize recovery. Early identification of symptoms and prompt medical evaluation are critical for effective management and facilitating a successful recovery from leg and knee injuries.
