Arthroscopic and magnetic reasonance tens

The purpose of the present study was to evaluate the accuracy of MRI compared with arthroscopy in staging of osteochondral lesions of the talus (OLTs). The authors prospectively investigated 50 patients (52 cases) who had undergone both MRI and ankle arthroscopy for OLTs. The 30 males (32 ankles) and 20 females (20 ankles) had an average age of 43 years (range 19-64 years). The correlations between MRI and arthroscopic stagings were also investigated. Preoperative MRI resulted in 7 stage I, 11 stage II, 25 stage III, and 9 stage IV lesions, and ankle arthroscopic findings in 3 stage I, 5 stage II, 35 stage III, and 9 stage IV lesions...

BACKGROUND: A type VIII superior labrum anterior posterior lesion represents pathologic posteroinferior extension of a type II superior labrum anterior posterior lesion with injury to the insertion of the posterior band of the inferior glenohumeral ligament. No reports in the literature describe arthroscopic treatment of a type VIII superior labrum anterior posterior lesion and its associated glenohumeral instability. HYPOTHESIS: Arthroscopic capsulolabral reconstruction is effective in alleviating pain and restoring stability and function in athletes with glenohumeral instability due to the type VIII superior labrum anterior posterior lesion...

In an arthroscopic-MRI correlation study of acute injuries to the knee it was found that anterolateral meniscocapsular separations of the lateral aspect of the knee were missed on MRI reporting. Eighty sports-related injuries of the knee were seen by experienced orthopaedic surgeons at the University of Malaya Medical Centre and at the National Sports Centre, Malaysia from January 1996 to July 1997. Fifty of the patients were suspected to have meniscal tears that were either lateral or medial on clinical examination and they were sent for MRI...
