PRP for treatment of Osteoarthritis

<a href=""></dt><dd class=

PRP has been used in surgeries, dentistry and aesthetics for many years now, but recently there have been a number of clinical studies published that support it’s use in treating osteoarthritis.

[1]Osteoarthritis affects 8.75 million people in the UK, and a third of people aged 45 or over has sought treatment.

One study[2] looked at 78 patients with osteoarthritis in both knees. Each knee had one of three treatments; either one PRP injection, two PRP injections, or one placebo saline injection. The patients’ knees were assessed at 6 weeks, 3 months and then 6 months post treatment. The results were impressive. Knees treated with one or two PRP injections all had a reduction in pain and stiffness, plus an improvement of function at 6 weeks and 3 months. At the 6 month point there was a reduction in results but pain and function remained better that pre-treatment. However the knees treated with the placebo injection saw an increase in pain and a decrease in function.

Another study[3] looked at patients with knee pain that had been present for around 14 months. Each knee underwent an MRI and then had one single PRP injection. Assessment was made at 1 week, 3 months, 6 months and 1 year with a second MRI also taking place at the 1-year point. The results showed that most patients had less pain, and the MRIs showed that the degenerative process has not progressed in the majority of knees.

Having previously worked in rheumatology, Dr Sister is very excited about the benefits PRP can bring his patients who suffer from osteoarthritis. He’s used PRP to treat his own elbow [link to previous article] and has completed a number of successful knee treatments.
