Worried about your recovery period after knee replacement surgery? You’re not alone! According to recent stats, almost 800,000 knee replacements are performed each year in the US, and an average recovery period ranges from 6 to 12 months.

Your healing period highly depends on your physical condition and the surgical implant quality. However, shortening the duration of the recovery period is completely in your hands.

Following your doctor’s advice and undergoing continuous physical therapy can help you fasten your knee replacement recovery.

Here are expert tips and guidance to speed up your healing process and get back to your foot within months.

Boost Your Knee Replacement Recovery

1. Follow Your Exercise Routine Strictly

Almost all physical therapists suggest that regular exercise helps you to build strength and gradually return to your everyday activities. Therefore, it is essential to strictly follow your exercise schedule suggested by your orthopedic surgeon or physical therapist.

According to the American Academy of Orthopedic Surgeons (AAOS), you can begin your low-impact exercises after your surgery. Your physician might suggest you start,

  • Walking for 30 minutes daily
  • 20-30 minutes of low-impact exercise

Remember, post-operative exercise will help you strengthen your knee muscles and prevent blood clot formation. So, it is crucial to follow your daily exercise routine to enhance your healing from surgery.

As suggested by your doctor, you can continue high resistance exercises after six weeks of knee replacement surgery when you can fully perform your daily activities.

2. Eat A Balanced Diet to Heal Faster

After surgery, your body is already bearing the wear and tear stress of surgery. This stress reaction elevates the need for healthy nutrition and maintaining a balanced diet routine.

Many orthopedic surgeons recommend avoiding food full of calories and have no nutritional value.

The doctors at Proliance Orthopedic Associates recommend the following diet to speed up your recovery:

  • Proteins: fish, meat, beans, and nuts will allow your muscles to gain strength and boost your immune system.
  • Calcium: Dairy products like milk, cheese, and yogurt will maintain strong bones and help to regain your energy.
  • Vitamin C: Fruits, vegetables, and potatoes will help your body make collagen and prevent infections by boosting your immune system.
  • Iron: nuts, dried fruits, legumes, and green leafy vegetables are high sources of iron that will fasten the production of blood cells and regain your energy levels.

3. Wear Knee Brace & Use Walking Equipment

Once you’re discharged from the hospital, your doctor will prescribe you to walk using crutches. After your surgery, your knee needs adequate rest to avoid any unnecessary strain that can hinder your recovery. Thus, you must be careful while moving and use walking aids whenever you move.

Wearing your knee braces will facilitate your recovery in the following ways:

  • Give extra support to your knee.
  • Help you to keep your knee straight.
  • Reduces discomfort after surgery.
  • Minimize pain and swelling.

Remember, braces and walking aids give rest to your knee joint so that you can recover at a faster rate. Most orthopedics surgeons recommend using crutches or walkers for 3 to 4 weeks after surgery until you can resume your strenuous activities.

4. Wound Care To Prevent Infections

One research estimated that 5.6% of a group of 180 people who had undergone total knee replacement developed surgical site infections.

You can prevent wound infections by following your orthopedic surgeon’s instructions. And if you properly monitor your wounds, they will recover faster.

According to Allina Health, it’ll take 2 to 3 weeks for your wounds to heal. Experts advise the following 5 steps to promote faster wound healing:

  • Do not soak your surgical site in water for the first 6 weeks after surgery.
  • Wash your hands with soap before touching your wound.
  • Do not scrub your wound
  • Keep it clean and dry
  • Watch for signs of infections that include yellow or green discharge, redness, fevers, or chills.

5. Right Knee Positions After Surgery

A TKR will cause discomfort and pain for some days. For the first 2 weeks of surgery, you must minimize any movements that can hurt your knee. Right knee positions will prevent discomfort and pain during this period, leading to faster recovery.

When seated or lying down, keep your leg straight and place a soft pillow under your knee to elevate it. Also, you should refrain from sleeping on your stomach for 3 to 6 weeks until your knee is completely healed.

Follow the above 5 steps and boost your knee replacement recovery in a few months.

5 Activities to Avoid During Knee Replacement Recovery

1. High-impact Activities

Until your knee completely heals, you must avoid any strenuous activity that may lead to a sudden jerking or twisting of the knee. Some high-impact activities that can hinder your recovery process are:

  • Running, jogging, or jumping
  • Football, basketball, soccer
  • Kneeling
  • Gymnastics or any high force exercise

Specialists suggest avoiding any high-impact activity for up to 3 months after surgery. So take complete rest for a few months and gradually resume your daily activities

2. Long Sittings

Prolonged sitting positions increase the risk of swelling and hamper the blood flow towards your lower limb. So, you must not sit for more than 45 to 60 minutes in the first 7 to 10 days.

According to new research, about 1 in 100 patients who undergo knee replacement will develop a blood clot that is also deep vein thrombosis. And sitting for a long time enhances the risk of blood clots. Therefore, it is essential to do low-impact exercises suggested by your orthopedic surgeon.

3. Wear Proper Shoes

After TKR, your foot swells up even with minimum activity. So, shoe experts recommend wearing shoes with more space, better grips, and decent arch support.

Experts recommend investing in quality walking shoes that positively impact your knee. You must buy shoes that have:

  • Decent arch support
  • Shock-absorbing cushioning
  • Has the right amount of grip
  • Easy to clean
  • Easy On and off
  • Expandable

4. Sitting on Low Chairs or Beds

Avoid sitting on low chairs and beds for about a few months as any stress on your knee while getting up can dislocate, twist or pivot your leg. After a few days of surgery, your physician recommends you get up or sit down using external support.

One of the best ways to avoid unnecessary stress on your knee is to sit on armchairs at an appropriate height. Your hips must not be lower than your knee, and your thighs must be parallel to the ground.

Also, refrain from sitting on overstuffed sofas or couches as much as possible.

5. Lifting Heavy Weight Objects

A knee replacement takes approximately 6-12 months for complete recovery. Although your knee might not feel pain after some months, you must not forget that it is still healing. And during the healing period, it is best to avoid lifting any heavy-weight objects that can put pressure on your knee.

However, if you are an athlete or a professional runner, your physical therapist will guide you with proper resistance training to strengthen your leg muscles. Following your therapist’s advised workouts will help train your body to lift heavy weights gradually.
