30 Μαρ 2011 · The anteriolateral portal was 97% accurate by real-time ultrasound imaging. The modified anteriolateral bent knee portal is an effective, accurate, and equivalent alternative to the standard lateral midpatellar portal for intraarticular injection of the knee. ClinicalTrials.gov: NCT00651625
The lateral midpatellar injection was performed with the knee almost fully extended (in 10 to 15 degrees of flexion), and the needle was directed from the lateral surface of the knee to the...
The lateral midpatellar site was found to have a 93% accuracy compared to the anteromedial and anterolateral with only 75% and 71% accuracy, respectively (Strength-ofrecommendation - SOR B)8. Ultrasound has been shown to increase accuracy rates as well, providing 95.8% injection accuracy for the knee joint compared to only 77.8% without using any
We hypothesized that a modified anteriolateral portal where the synovial membrane of the medial femoral condyle is the needle target would be highly accurate and provide equivalent clinical outcomes as the standard lateral midpatellar approach for intraarticular injection of the knee.
For lateral midpatellar approach, the injection was made between patella and patellar groove of femur at mid lateral patellar junction with the knee in an extended position . In the superolateral patellar injection, the needle was inserted 1 cm above and 1 cm lateral to superolateral margin of patella in a 45° angle cephalolateral to ...
Injection via the MMP approach is undertaken with the needle entering the medial aspect of the knee joint under the middle of the patella (midpole), and is directed towards the lateral patellar midpole3).
