Patient Specific Knee Replacement

This procedure is performed in the same manner as for Total Knee Replacement. The same tried and tested implants are used but a sophisticated technique is used to plan the procedure. 

Indications (why I do the procedure)

As with total knee replacement, this procedure is performed for pain relief. It is a surgical technique used when non-operative treatments including physiotherapy, analgaesia (pain killers) and lifestyle modifications no longer control your pain.

Implants used

I use only ‘tried and tested’ implants. I am a strong believer in evidence based medicine and use implants with a long heritage (they have been in use for many years and have good evidence that they work well). The only addition to the procedure is the production of computer generated patient specific moulds that fit your knee precisely.

Pre-operative planning

Following listing for the procedure, you will have an MRI scan (magnetic resonance imaging), a painless scan taking less than an hour. This allows me to make a precise plan of your operation, based on your exact knee anatomy. Using a sophisticated computer package, your knee is mapped and the best fit of implant is selected. A specific mould is produced that fits only your knee and is used during the operation. This process generally takes less than 6 weeks.

Hospital Admission and Surgery

You will generally be admitted on the day of surgery. Your surgery will be performed through a short incision on the front of the knee, covered with a dressing after the operation. You will receive physiotherapy shortly after your operation to improve your mobility prior to discharge. This physiotherapy is essential to knee movement in the immediate period and aids range of movement in the longer term. The anesthetist, the nursing staff and I will optimise pain relief to make this post-operative period as comfortable as possible and allow early and safe mobilisation. We would expect you to be able to go home on crutches 3 to 4 days after your operation.


I will generally see you 6 weeks after your operation in a specialist clinic. This appointment will be made for you by the ward staff, prior to your discharge. If you have any problems after the operation you can contact the team at any time, either the clinic nurses, the ward or my secretary.
