Abstract:
The objectives of this study were to find out the knee joint diseases using high resolution ultrasound in patients who complaining of knee joint pain and swelling. And characterizing the sonographic feature of each cause, as well as to detect the most common knee joint diseases that affect the Sudanese populations and how it does relates to the age, sex. And To correlate between different knee joint diseases and side of pain, site of pain , nature of pain , duration of pain, joint movement, and presence of swelling.
This study was conducted in Elsahafa Medical Complex and Omdurman Military Hospital from November 2011 to March 2012.
Fifty patients were investigated (23 male, 27 female) aged between 20 -70 years, all of them had a knee joint pain, and all patients who were aged below 20 years were excluded.
The researcher found that in 34 patients (68%) there were detectable sonographic abnormalities, and in 16 patients (32%) the scanning result was normal.
The result showed that: the anterior knee compartment is the most compartment affected with pain, and the causes of the pain are suprapatellar joint effusion and bursitis (28%) of the total patients. cartilaginous edema of the patella-femoral articulation (6%). and patellar tendonitis (4%).
The posterior knee compartment is second compartment affected with pain and the causes are baker's cyst (14%), ruptured baker's cyst (8%), deep vein thrombosis of the popliteal vein (2%), and Periosteal desmoids tumor (2%).
The medial knee compartment is a third compartment affected with knee pain, and the detected cause is Lipoma only (4%).
The lateral knee compartment is a least compartment affected with pain, and the researcher doesn't detect any cause sonographically.
In view of this result the researcher found that the ultrasound has a great value in evaluation of the knee joint pain and swelling.
