Proyección de Rosenberg en la evaluación radiológica de la osteoartrosis de rodilla

Background: Knee osteoarthritis is highly prevalent in our country. An early diagnosis is very important to provide an accurate and early treatment, and eventually delay its progression. Aim: To compare the diagnostic yield for osteoarthritis of two projections in knee Xray examination. Material and...

An early diagnosis is very important to provide an accurate and early treatment, and eventually delay its progression. Aim: To compare the diagnostic yield for osteoarthritis of two projections in knee Xray examination. Material and Methods: We evaluated 44 knees with conventional (AP weight-bearing, in full extensión) and Rosenberg (PA weight-bearing in 45 degrees of flexión) X ray projections in 32 patients (24 women and 8 men), aged 26 to 78 years. All patients were symptomatic at the time of evaluation, with a suspicion of knee osteoarthritis. Both projections were analyzed and compared. Results: Joint space in the lateral compartment with conventional AP weight-bearing and Rosenberg projections were 8.6±11.5 mm and 7.8±10.9 mm, respectively (NS). The joint space for the medial compartment were 8.2±10.9 mm and 6.7±8.6 mm, respectively (p <0.05). Conclusions: Rosenberg prqjection is more sensitive to detect knee joint space narrowing as compared with conventional AP weight-bearing prqjection, at least in the medial compartment ofthe knee. Therefore, Rosenberg prqjection should be included in the initial study of any patient with suspicion ofknee osteoarthritisinfo:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.136 n.7 20082008-07-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872008000700009es10.4067/S0034-98872008000700009
