A study on 50 subjects with anterior cruciate ligament (ACL) injuries and 50 uninjured subjects hinted at a higher danger of ACL injury for people with hyperpronation of the foot and ankle complex. The navicular drop test was utilized to ascertain their hyperpronation, but further research may be neededin light of recent trends involving evaluation of abnormal biomechanics in rehabilitating lower extremity pathologies. The investigations generated biomechanic information which could provide athletes with valuable knowledge needed in injury prevention.

The etiology of Osgood-Schlatter's disease remains a topic for debate. Previous studies by Ogden and Southwick (Osgood-Schlatter's disease and tibial tu bercle development. Clin Orthop 116: 180-189, 1976) strongly support the concept of multiple mi croavulsions of the anterior surface of the developing ossification center of the tibial tubercle as the under lying cause.Orthopaedic literature fails to associate Osgood- Schlatter's disease with traumatic disruption of the extensor mechanism of the knee. Though the mech anism of injury for such trauma is as common as Osgood-Schlatter's disease itself, such occurrences are rare.Failure of the point of attachment of the patellar tendon in a patient with markedly symptomatic Os good-Schlatter's disease tends to confirm the etio logic concept of Ogden and Southwick.Patients with markedly symptomatic Osgood- Schlatter's disease who engage in activities involving rapid deceleration or vigorous vertical acceleration are in a relatively high risk category for disruption of the extensor mechanism. Traumatic avulsion of the patellar tendon in such a patient establishes this re lationship. [ABSTRACT FROM PUBLISHER]
