Over 70,000 people in England and Wales undergo knee replacement surgery each year, with most patients being 65 and older. However, for younger individuals, especially athletes, knee surgery can be a daunting decision. For Karl Hicks, a passionate runner, severe knee osteoarthritis threatened not only his mobility but also his ability to continue competing.
Determined to find a solution that would allow him to stay active, Karl sought the expertise of Mr. Pierre Nasr, a highly regarded orthopaedic surgeon specialising in knee replacement surgery. Under Mr. Nasr’s expert care, Karl underwent a partial knee replacement, a minimally invasive procedure that successfully restored his mobility and allowed him to return to competitive running.
This is Karl’s inspiring journey from knee pain to recovery, demonstrating the benefits of partial knee replacement and the importance of choosing a specialist surgeon.

Karl’s Journey: From Knee Pain to Recovery
Karl had been struggling with severe knee osteoarthritis in the medial compartment of his knee joint. Over time, the cushioning cartilage wore away, causing bone-on-bone contact, chronic pain, and inflammation. Despite trying conservative treatments such as physiotherapy, anti-inflammatory medications, and lifestyle adjustments, his symptoms persisted.
Doctors initially recommended a total knee replacement, but Karl feared that this would prevent him from running competitively. Unwilling to give up his passion, he sought a second opinion from Mr. Pierre Nasr, a specialist in joint replacement surgery, at Three Shires Hospital in Northampton.
The Solution: Partial Knee Replacement
After a thorough assessment, Mr. Nasr determined that Karl was an ideal candidate for a partial knee replacement. Unlike a total knee replacement, which replaces the entire joint, a partial knee replacement surgery replaces only the damaged section of the knee while preserving the healthy compartments of the knee and crucial ligaments like the ACL.
Key benefits of partial knee replacement include:
✔ Minimally invasive knee surgery with a smaller incision
✔ Faster recovery time compared to a full knee replacement
✔ Preservation of the knee’s natural range of motion
✔ Reduced risk of complications such as deep vein thrombosis
Understanding Partial Knee Replacement Surgery
A partial knee replacement procedure is a surgical procedure that removes only the damaged part of the knee while leaving the healthy bone and tissue intact. It is most commonly performed when arthritis is limited to one part of the knee, such as the medial compartment.
How It Differs from Total Knee Replacement
Partial Knee Replacement | Total Knee Replacement |
Replaces only the damaged part of the knee | Replaces the entire knee joint |
Smaller incisions and less invasive | Larger incisions and more invasive |
Faster recovery (often home within 24 hours) | Longer hospital stay and recovery |
Preserves natural knee movement | May feel less natural post-surgery |
The Procedure and Recovery
Karl’s surgery was performed using the partial knee replacement system, a trusted implant with a strong track record in the National Joint Registry.
Surgical Procedure
- Anaesthetic: Karl received a spinal anaesthetic, ensuring a pain-free experience during surgery.
- Incision & Implant: A small incision was made at the front of the knee. Using advanced surgical techniques, Mr. Nasr removed the damaged area and replaced it with an implant while preserving the healthy knee joint.
- Minimal disruption: The surrounding tissues and deep veins remained largely unaffected, reducing post-operative complications.
Recovery Time & Return to Running
After the surgery, Karl was able to return home within 24 hours. He committed to an intensive physiotherapy programme, focusing on strengthening his quadriceps and hamstrings, improving balance, and regaining flexibility.
Thanks to Mr Nasr’s expertise and Karl’s dedication to his rehabilitation, he was back to competitive running in just eight weeks after surgery. He later competed at the World Masters Athletics Championships in Sweden, where he finished fourth in the 5000m and won a silver medal in the 8000m cross-country event.
