My doctor prescribed a Splint by a company called Dynasplint. You wear it 6 to 8 hours a day. It applies backward Pressure from 5 to 25 pounds adjustable to slowly stretch and bend your knee. You can achieve about 3° of stretch per week. You wear it while sitting and watching TV. The rental is about $200 a month and covered by most insurance companies. However after wearing it a couple of days I realized that you can achieve the same stretch while watching TV by resting your foot against an immovable object. By moving your foot About an inch you can change the amount of pressure by 5 pound increments. I plan to send the split back.
Expect to get about 10° per month which is consistent with what the company advertises. This is a slow but sure way to get your range of motion back .
I have read that if you have limited range of motion prior to replacement...you will have that same level of range of motion. I am between 110 and 120; however, the limited motion I had previously tightens up my hamstring so I am doing a lot of stretching. I surgery was 5 months ago. I don't have much pain...from time to time I have some on the inside of my knee area, but the stronger my quad and hamstring gets the less and less pain I feel.
Hi there!
Poor range of motion can be caused due to several reasons such as muscular issues, inflammation, loose bodies etc. It might be worthwhile getting a review with your treating orthopedician to check if any of the factors is involved. Meanwhile it si advised to continue with physiotherapy.
Hope this is helpful.
Take care!
