Some doctors have bad aim for bad knees

People with osteoarthritis in the knee should watch out if they’re on the receiving end of drugs such as corticosteroids, which are injected directly into the knee to relieve the symptoms of arthritis by reducing the inflammation in the knee joint.

But the drugs can’t work if they’re injected into the wrong place. Doctors have been found to miss the correct injection site up to 25 per cent of the time – regardless of how experienced they are (J Bone Joint Surg Am, 2002; 84: 1522-7).
