What condition is characterized by acute onset of limp with knee and thigh pain?

The condition characterized by an acute onset of a limp accompanied by knee and thigh pain is indeed slipped capital femoral epiphysis. This condition typically affects adolescents during their growth spurts, and it occurs when the femoral head slips from its normal position at the growth plate.

Patients often present with hip pain that may be referred to the knee, and they frequently exhibit a noticeable limp due to the impairment in hip movement. The acute onset of symptoms can sometimes be mistaken for less severe injuries, but immediate medical evaluation is crucial because neglected or delayed diagnosis can lead to serious complications, including avascular necrosis of the femoral head.

In contrast, Osgood-Schlatter disease is usually associated with localized knee pain that worsens with activity and is not characterized by an acute limp arising from hip dysfunction. Legg-Calve-Perthes disease can present with hip pain and a limp, but it typically develops gradually rather than acutely. Septic arthritis usually includes signs of infection, such as fever and marked joint swelling, and it also typically presents differently regarding the pain pattern and severity.

Recognizing slipped capital femoral epiphysis is vital for timely treatment, which may involve surgery or monitoring, depending on the degree of slip and
