Mr Dennis Kosuge — Consultant Orthopaedic Hip and Knee Surgeon

Mr Kosuge is a fully accredited Consultant orthopaedic surgeon (BMedSci, FRCS Trauma & Orthopaedics) with a specialist practice in hip and knee surgery. He treats private patients at The Rivers Hospital, Sawbridgeworth, and NHS patients at The Princess Alexandra Hospital, Harlow.

His approach is conservative first. Surgery is recommended only when it is genuinely the right step, and non-surgical options are explored thoroughly before an operation is considered. Patients consistently value the time he takes to explain the diagnosis and the options honestly, which is reflected in more than 450 five-star patient reviews and a Certificate of Excellence from iWantGreatCare awarded every year from 2019 to 2025.

• Knee replacement — total knee replacement, including robotic-assisted surgery (see below).

• Partial knee replacement — resurfacing only the worn part of the knee, for suitable patients.

• Knee arthroscopy — keyhole surgery for problems such as a torn meniscus or loose body.

Robotic-Assisted Knee Replacement at The Rivers Hospital

The Rivers Hospital now offers the VELYS™ Robotic-Assisted Solution for total knee replacement, and Mr Kosuge performs robotic-assisted knee replacement there. Robotic assistance does not replace the surgeon. It adds a detailed, patient-specific plan and real-time feedback that help position the implant and balance the knee with a high degree of accuracy. Mr Kosuge offers both conventional and robotic-assisted total knee replacement and will be happy to discuss which is more appropriate for your knee at consultation.
