Anyone do BJJ with an artificial knee?

I’ve needed a knee replacement for about the last 5-10 years but kept putting it off because of BJJ. My doc can’t give me a definitive answer on what my limitations will be in BJJ. He said “people who get new knees don’t usually do what you do.” Lol.

Anyone still doing BJJ after getting a new knee?

I have a friend who’s 55 years old and has a knee replacement. He still does BJJ and rolls, and can roll hard. He mainly passes on his knees and does not employ standing passes much. Many of his limitations seem to be mental, but I’m sure he can’t do some of the things a young 20 yr old might do. He’s a black belt and a good one


Glad to hear he can still pass on the knees! That’s my biggest area of concern. I’m concerned about being able to kneel in someone’s guard.


Really, that’s all he does. Play half guard > sweep, pass on the knees, go to side control, and submit or restrain from there

He probably could pass standing but isn’t comfortable with it, and much. of it seems mental opposed to physical limitations

So good to hear this. This is totally my game, awesome to hear I can continue it. I’ve had ACL reconstructions on both my knees … a knee replacement is likely in my future.


I’m a physical therapist and jiu jitsu black belt. I have yet to work with a jiu jitsu athlete who wanted to get back following a full knee replacement. Unfortunately there is no research on this topic specifically.

I found this article on return to sport following hip / knee replacements for judo. I think judo would actually be more challenging on the knee than jiu jitsu. Looks like the return to sport data is promising.

Michael Bisping had a double knee replacement and he is doing wild stuff: running, kicking the heavy bag.

Clinically I am most worried about the lack of knee bending and getting comfortable kneeling (kneecap on the mat). Knee flexion (bending ROM) at best will be 140 degrees, and not everyone gets that much ROM. Doing a full kneel might be challenging. Take rehab seriously and get your mobility as good as possible.

There are different implants, some remove the ACL and use a metal post. This implant would make standing passing and dynamic movements more challenging. Some implants spare the ACL. This variant would be much better for maintained athletic movements. You would have to discuss with the surgeon what approach he wants to use and what impact options there are available.

If I get the opportunity to work with a jiu jitsu athlete following a knee replacement I will probably do a case study and talk about it on my social media page: h
