Medial approach to injection of the knee joint

Based on contributions from Dr Elspeth Wise and Dr Alan Walker on behalf of the Primary Care Rheumatology and Musculoskeletal Medicine Society

  • the patient should be resting on a couch with their knee extended

  • the space between the patella and the femoro-tibial articulation should be palpated

  • the needle is inserted at the mid point of the medial border of the patella and is directed laterally and slightly posteriorly

  • it may be helpful to apply pressure to the lateral aspect of the patella whilst injecting so as to tilt the patella laterally and open up the medial space
