Read this article below to find out about the general outcomes in the different types of knee replacement surgery, as distinguished consultant orthopaedic surgeon, Mr Sam Yasen, provides us with the key nuggets of information. 

What is a knee replacement, and what types are there?

When we talk about knee replacements, we're talking about a resurfacing procedure of the joint. Most knee replacements involve reskimming the end of the thigh bone and the top of the shin bone.

 

There are two types: total knee replacements and partial knee replacements. Both types are performed to recreate the mechanics of a full, normal knee joint. Partial knee replacements feel more natural as the knee ligaments aren't violated as much as in total knee replacement surgery. 

 

What are the outcomes in knee replacement surgery?

Outcomes can be variable. Overall, one can achieve excellent results, especially if the joint is treated appropriately. We often say that around 20 per cent have excellent outcomes, 60 per cent have good outcomes, and about 20 per cent of people are less happy with their results. About one to two per cent of patients suffer complications.

 

Bad outcomes generally tend to be age-related. If you are over 80, you are likely to have a worse outcome, but if you are 50 or under, you're likely to have a good to excellent outcome.

 

Are total knee replacements better than partial knee replacements?

The longevity of a total knee replacement is slighly better and longer when compared to that of a partial knee replacement. Good outcomes that last for 10 years or longer are around 97 per cent for total knee replacements and around 90 per cent for partial knee replacements.

 

Are there any advances in knee replacement surgery that may help me?

Yes, there are many advancements, but some may not be useful or appropriate. The most important thing is the diagnosis. Once a decision has been made, then executing the technical plan to perfection is the next step.

 

Computer-navigated knee replacement is a great technological advancement, as well as robotic surgery, which has come into force within the last few years. Personalised, custom-made implants are also another option and have been a great recent advancement when it comes to performing knee replacement surgery.

 

Are there alternatives to knee replacement that should be considered?

We absolutely should consider and discuss alternatives. Alternatives such as injection therapies, meniscal transplant technologies, realignment options, and ligament reconstructions can all be considered.
