• Total Knee Arthroplasty - Knee Replacement

    What are the causes of knee pain and disability?

    Having a healthy knee is important. Over a lifetime there is a cumulative wear and tear on our knee joints. Chronic knee pain can continue to progress and cause many issues with a person’s walking or everyday activities. Arthritis and general deterioration with aging are the most common causes of a knee disability that require a total knee replacement. Osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis are just a few of the common causes of knee degeneration. These conditions usually cause a degeneration in the knee joint that results in a bone on bone joint deformity.

    Considering total knee replacement is a big decision for many people. A person should consult with a doctor if a total knee replacement is a good option to improve their knee pain. 

    Who is eligible for a Total Knee Replacement? 

    Indications for a total knee replacement include:  

    • Intractable knee pain
    • Walking, going up stairs, getting out of a chair is painful
    • Knee pain during sleep
    • Bone or joint deformity
    • Chronic irritation or inflammation to the knee 

    About 90% of the candidates who receive a total knee replacement experience a significant decrease in overall knee pain after the procedure. If your knee pain related to arthritis severely impacts your daily life and function, then you should consider consulting with your doctor regarding your options for a knee replacement.

    What are Common Treatments for Total Knee Replacements?

    The most common preventative and post-operative rehabilitation is physical therapy. Performing physical therapy even before surgery can vastly improve outcomes and can increase performance after surgery as many studies show.

    • There is a positive correlation between preoperative and postoperative function following joint replacement
      • Improved functional ability 1 month preoperatively correlates with improved functional ability 3 months postoperatively
    • Pain and flexibility prior to joint replacement was predicative of pain and flexibility following surgery
    • Patients undergoing total knee replacement receiving "prehab" intervention improved sitting and standing preoperatively 
      • Control group reported increased pain with walking and and going up stairs preoperatively 
      • Sitting and standing ability was maintained in prehab group postoperatively
    • 6 minute walk test and quadriceps strength was decreased in control group postoperatively
      • Control group also demonstrated quadriceps strength asymmetry between operative knee and nonoperative knee
    • 6 minute walking test distance was greater in patients who received rehab
    • Going up and down stairs, sitting and standing, strength and pain improved 3 months after surgery in prehab group

    F.I.T. physical therapy can help improve range of motion, strength, stability, balance, and overall function.
