The Biomechanical Basis for Rupture of Extensor Mechanism of Knee Joints at Different Sites

Rupture of the extensor mechanism knee joints is rare in patients without any systemic disease. Many reports have described tendons getting ruptured at various sites mechanism. We report a case patellar tendon avulsion from tibial tuberosity on right side and quadriceps patella left sustained one accident. A 54 years old man presented with above non-identical bilateral rupture who had no pre-existing systematic diseases was not steroid treatment. Tendon ruptures were always related to degenerative/inflammatory conditions or usage steroids. However, reason for different parts after minor trauma tendinopathy significant normal patient well explained. believe that degree flexion time injury plays an important role site
