A total knee replacement, also known as TKR or Total Knee Arthroplasty, is a medical procedure that is used to reduce knee pain and improve your activity levels.[13] TKR is a highly successful and frequently performed surgical intervention. The procedure is capable of successfully improving health-related quality of life soon after the surgery is complete, with some physical therapy milestones being achieved already within the first 7-14 days after surgery.[5]

However, what can you expect multiple years after surgery? As with any medical procedure, TKR can present both long-term risks and benefits. Considering the long-term outcomes of total knee replacement can provide you with better insight into whether total knee replacement is right for you.

In the video below, Kinesiologist Milena explores the intermediate and long-term quality of life after total knee replacement at 1, 5, 10, 15, and 20 years after a total knee replacement.

Read the full blog that discusses what to expect from 1 to 20 years after a knee replacement here.

Curovate has a recovery plan specifically for Total Knee Replacement. This plan helps you to stay on track with your recovery by using video-guided exercises, reminders, and the ability to measure your knee bending and straightening (called range of motion). Your exercises will gradually get harder as you begin to regain your knee movements and strength, helping you to recover over time using our physical therapy app, Curovate.

To try the app today, click the download links below. If you’re wondering what to expect after your surgery, you can read our blog on 6 Things You Need to Know After a Total Knee Replacement.
