Hi All
Does anyone have experience of Zwifting post a knee replacement?
I’m particularly interested in 3 things:
Any comments or advice is most welcomed.
Many thanks
Some discussion recently over here…
my wife has had both knees replaced. Riding the bike is highly recommended to aid recovery along with other physio. After the second knee replacement she was back on the bike in a couple of weeks. No you will not be applying full force - it takes time to build back up. No you will not get full flex for a while - it takes time. You must be patient. If it hurts back off.
I can expand on my paragraph in the other thread.
My knee had arthritis and a previous meniscus tear that was repaired. While sprinting on Zwift, the knee “popped”. Literally blew the cartilage apart. After 6-7 months living with bone-on-bone (various reasons for the long wait), the knee was replaced.
I had PT in the house the day after surgery…the first two weeks of PT were in the house. The entire goal was to increase range of motion. That hurts…no two ways about it but it helped. I iced as much as I could stand including overnight. I would wake up after 3-hours of sleeping freezing my ass off. I used one of the circulating machines that are all over Amazon. I filled water/gatorade bottles and froze them. Work much better than the ice blocks.
In the 2-3 week range I started using a cane and only used a walker at night getting out of bed. Swelling started to reduce at 3 weeks (knee to groin…thigh swelled more than the knee). Improvement all-around started daily at 3 weeks; very noticeable.
4 weeks to the day I could finally get the pedals around on my bike. I then got on a 3.5 hour flight. dumb…very sore when we landed. I did not stand and walk enough on the flight.
Started going on short walks (.5-.7 miles) at 4 weeks. By 6 weeks I could walk 2-3 miles and spin very easy on a bike for 30-40 minutes.
At 7 weeks returned home and got on Zwift…45 minutes 120 watts and less. by this time my swelling was pretty much gone except for around the knee. I had no thigh muscle being inactive for the time prior to surgery. All bone from knee to hip… That 45-minute ride expanded what muscle was left. The next two days hurt just as much as immediate post-surgery.
Started PT and they used cycling just to loosen since I was doing it on my own. After 11-months I still get a bit of stiffness around the knee. My 30-40 minute power is back to pre-knee blowout. My 60 minute power is still down 5-8% but I have been more focused on 90-minute plus zone two and have not done any racing to build that stamina strength. My top sprint wattage is down 100 watts or so but I think that is mostly reluctance on my part. I do not do “workouts”. I ride how I feel. The knee is strong but higher wattage efforts for 4-7 minute durations, the knee will start feeling “chunky”. I think the muscle and implant connectors are still building.
Range: Once I hit 120 degrees after 7 weeks, surgeon was happy. Told me to keep doing what I am doing and do not run. No problem with that. I have to concentrate on straightening the leg while I walk and I work on that while watching TV. I am bow-legged and my “straight” leg was actually past straight…I can do that on my right still, but that left leg stops straight.
Note this is all my experience…I am running 100 kg or so…my FTP is currently 218. I have had big improvement over the last three weeks as i am recovered from a shoulder scope and am pushing just a bit.
Anything else let me know. Good luck!
