Is magnetic resonance imaging reliable for the evaluation of the ruptured or healed anterior cruciate ligament?

Magnetic resonance imaging (MRI) is the preferred imaging technique to evaluate the intact, ruptured or healed anterior cruciate ligament (ACL). However, its effectiveness in the diagnosis of chronic tears with synovialization has not been searched. During conservative treatment of torn ACL, there is a reparative process with proliferation of synovial scar tissue which may produce a bridge. This healing, so called synovialization, may cause ACL to be misdiagnosed as intact on MRI. This is true for old ruptures of ACL. Magnetic resonance imaging is reliable in the evaluation of acute ACL ruptures. However, MRI is not reliable to evaluate the stability of the healed ACL after conservative treatment, and the ruptures due to degenerated ACLs

Neglected bilateral congenital dislocation of the patella

Congenital dislocation of the patella is a disorder that presents with dysfunction in extensor mechanism. Although congenital dislocation of the patella mostly occurs in children with genetic disorders, it may also occur in totally healthy children, despite rarely. In this article, we report a 16-year-old male patient who referred to our clinic with complaints of gait disturbance, frequent falls, and muscular weakness in lower extremity. The patient had no complaints during walking, but had difficulty in running and walking up and down the stairs. It was observed that the range of motion of the knee joint was completely painless and the quadriceps muscle strength was evaluated as 3/5. An evaluation of computed tomography and magnetic resonance imaging results showed that the patella was dislocated. It became clear with magnetic resonance imaging that extensor mechanism was continuous but patellar tendon was not attached to its anatomical position. Surgical treatment was not planned because the patient did not describe any pain complaint and there was no limitation of joint movement, he could walk without support and without device and also refused to be operated. The choice of treatment should be based on the patient's preference, and pain and functional status

One patient, one bone, and two different tumoral lesions

In this article, we report a 67-year-old female patient who has two different tumoral lesions located in left humerus with clinical and radiological findings. Previously, the patient was diagnosed as impingement syndrome in shoulder, but, tumoral lesions were detected on the radiograms incidentally during evaluation
