A runner completed the London Marathon and the Great North Run after undergoing years of surgery and treatment for a fractured knee.

Carol Shone, from Wrexham, sustained the injury after her chocolate Labrador puppy Skye ran into her, shattering her left knee.

Before the incident, the 60-year-old was a keen runner and regularly attended gym classes.

However, the accident left her in 'excruciating' pain.

Mrs Shone spent years in and out of surgery, having her knee reconstructed and then eventually replaced.

Despite the knee replacement, Mrs Shone's pain persisted, and she faced significant mobility issues.

Due to her employer's private medical insurance, she was able to seek private treatment, which led her to Spire Yale Hospital Wrexham.

There, consultant orthopaedic surgeon Tony Smith successfully performed the knee replacement.

However, the pain continued, and Mr Smith suggested Mrs Shone consult with Professor Thomas Haag, a renowned pain management consultant at Spire Yale Chesney Court Outpatient and Diagnostic Centre.

Professor Haag, with more than 28 years of expertise in the field, recommended sensory denervation of the left knee using cooled radiofrequency—a procedure targeting the knee's pain-related nerves.

Professor Haag said: "This is a minimally invasive treatment which takes approximately 40 minutes to complete.

"It’s carried out using a local anaesthetic, so hospital admission is not required."

Mrs Shone underwent the procedure and had six nerves treated.

She said: "I experienced very little pain—more of a sensation.

"The last nerve was the most uncomfortable, but I chose to stay awake rather than go under general anaesthesia.

"I was able to walk out after pain-free."

The treatment proved successful, allowing Mrs Shone to focus on regaining her mobility.

She recently completed the Great North Run in Newcastle and walked the London Marathon in April, raising funds for Macmillan Cancer Research.

She said: "Now that the pain is gone, I can focus on regaining my mobility.

"The procedure was absolutely worth it.

"Both consultants at Spire Yale were fantastic, and I could see Professor Haag’s joy at the progress I had made.

"I am incredibly grateful to them and the wonderful staff at the hospital who took such great care of me."

Professor Haag said: "Some patients who undergo successful surgery are unfortunately left with ongoing pain which can also be treated in this way.

"In fact, this is the only non-surgical treatment option recommended by NICE for mild to moderate knee osteoarthritis."
