Abstract
Background: Ultrasonography is a noninvasive imaging modality used for the assessment of the musculoskeletal system. It can provide clinically useful information on a wide range of pathologic conditions affecting components of the knee joint, including the tendons, ligaments, muscles, synovial space, articular cartilage, and surrounding soft tissues. Now our concern of this study is to find out the modality of investigation of choice with accuracy, promptness and cost effectiveness.
Materials & Methods: In this prospective interventional comparative study patients of all age group of either sex attending the orthopaedic OPD of IPGMER & SSKM Hospital with clinical features suggestive of soft tissue around knee were included in the study during the period of Feb 2008 to Aug 2009. Sonography technique for evaluation of soft tissue injuries of knee as per AIUM 2007 (American Institute of Ultrasound in Medicine) standard protocols for knee joint sonography- The examination is divided into 4 quadrants (anterior, medial, lateral and posterior).
Results: Maximum number of patients belonged to 20-30 age group, which was comprised 36% of the whole study group. The average age of the study group was 32. Male subjects were showing definite male preponderance. In 64% of cases right knee joint was involved. Out of 100 patients, 48 cases showed ACL tears, 22 patients showed PCL tear arthroscopically. Out of 48 ACL tears confirmed by arthroscopy the diagnosis by USG was just 21 out of 48.
Conclusion: Ultrasound is a reliable, noninvasive method for diagnosing injuries to the tendons, ligaments, and muscles of the knee. It is important to recognize the limitations of this method for examining the menisci and bony lesions. In experienced hands, ultrasonography can play an important role in the assessment of pathologic conditions involving the knee joint.
