02 / Her knee story
Beyond the pool.
Back to everyday life.
Sharron is known for a life in sport. But the knee symptoms she described also affected exercise and day-to-day activities. Her priority was finding a way forward after years of injury and surgery.

A knee with a long history
The clinic’s published account records an ACL injury in 1995, nine reconstructive operations and advanced arthritis in her right knee by 2022. Further surgery was something she wanted to avoid if a suitable alternative was available.

Assessment before a decision
In September 2022, Sharron had an MRI scan and movement analysis with Professor Lee’s team, followed by an Arthrosamid injection. The films below show the imaging review and movement testing that formed part of her visit.

Following her progress
Her early video update describes less creaking and grinding in the knee and a return to cycling. Professor Lee also explains how the team followed her movement over time, alongside her own account of how she felt.

How Arthrosamid worksRead Professor Lee’s film transcript
Professor Paul Lee
We have been monitoring Sharron’s movement, monitoring her jumping, monitoring her landing and acceleration, deceleration, as well as smoothness of a joint. Before, after and long-term follow-up.
We also have done an MRI scan before Sharron’s Arthrosamid injection. We have three months’ data, six months’ data and getting along for the next 12 months’ data. It is something that we will continue to monitor and present when we have all the results.
Sharron was then injected with Arthrosamid under local anaesthetic. We have used the ultrasound scanner to identify the knee joint and ensure that the injection is entered into the joint before we change the needle to inject the Arthrosamid.
Following the injection, Sharron has been doing very well. She told me that she had been for a 34 miles bike ride last week and her knee is doing great.
