An effective technique for corticosteroid injection into the knee joint

Local injection of a corticosteroid into the knee joint is a commonly used modality for the treatment of various inflammatory processes. Injection of these agents at the superomedial or superolateral poles of the patella have led to problems with pain and discomfort for the patients, as well as damage to the chondral surface of the patella. Injection through the patellar tendon can lead to side effects related to injection into the fat pad and into the anterior cruciate ligament. These problems can be avoided by using the inferomedial or inferolateral poles of the patella as a needle insertion site.
