As with all surgeries, recovery time can vary depending on the patient, type of surgery, type of damage repaired, and their physical and mental condition. Most patients won’t have pain after the first few months after knee replacement surgery. It can take up to 2-3 months to return to most activities of daily living and 6 months to one year before your knee is strong and resilient and you begin to forget you had a knee replacement. For the best possible experience with your joint replacement, contact SPORT Orthopedics + Physical Therapy at 469-200-2832 today.
Knee Joint Anatomy
Knee joints are large hinge joints that connect the thigh bone (femur) with the shinbone (tibia). There is also a smaller bone that runs beside the shinbone and the kneecap at the front of your knee. Ligaments surround these bones, keeping the knee steady, connecting bones to each other, and then tendons attach the muscles to the bones.
- Anterior Cruciate Ligament (ACL): keeps the shinbone from tibia from sliding forward on the femur.
- Posterior Cruciate Ligament (PCL): keeps the tibia from sliding backward on the femur.
- Medial and Lateral Collateral Ligaments (MCL & LCL): on either side of the knee, keeping the bones from shifting from side to side.
There are two cushions made of cartilage where the tibia and femur meet, these are called the medial and lateral meniscus. They are shaped like a “C” and provide shock absorption, keeping the two bones from rubbing together. Bursae are also found within the joint. They are sacs that provide lubrication for movement.
Knee Replacement Surgery: Total Knee Replacement vs Partial Knee Replacement
Both a total knee replacement and a partial knee replacement are surgical procedures performed by an orthopedic surgeon to replace damaged bony surface and cartilage, or the cushion between your joints.
Total Knee Replacement
Total knee replacement surgery is when all the damaged bone and cartilage of the knee is replaced with metal or plastic components. This surgery can help ease the pain and make the knee function better. Patients that suffer from knee arthritis or a severe knee injury are most commonly considered for this procedure.
Partial Knee Replacement
Partial knee replacement surgery normally lasts about one hour and is performed under spinal, epidural, or general anesthesia. Only the damaged portion of the knee is replaced during this procedure. A partial knee replacement is a minimally invasive procedure that is an alternative option for those who have damage to the knee in just a single limited area.
What to Expect from Knee Replacement Recovery and How to Prepare
The recovery period after knee replacement surgery is crucial to the success of your procedure. You will typically be in the hospital for one night and some even go home the same day. You’ll be busy getting rest, taking care of your knee, and beginning physical therapy. It’s best to prepare your home well before surgery.
Recovery Room
Right after surgery is when your rehabilitation begins. The day of surgery, you will have the help of a Dallas physical therapist to stand up and walk using an assistive device, such as a walker, cane, or crutches. You will have help from a nurse or occupational therapist to change bandages, dressing, bathing, and using the bathroom. The physical therapist will show you how to get in and out of bed and how to move around using the assistive device. They might ask you to sit at the side of the bed, walk a few steps, and then transfer yourself to the bedside commode.
The day after surgery, you may walk for brief periods of time using the assistive device. Your activity level will increase gradually as you recover from surgery. You can shower the day after surgery if our surgical team used waterproof dressings. If waterproof dressings were not used, you will have to wait for 5-7 days before showering and avoid soaking the incision for 3-4 weeks so that it fully heals. Your physical therapist may ask you to try to climb a few steps at a time. At this stage, you will need to work on achieving full knee extension.
Recovering at Home
Your surgery’s success will depend on how well you follow your surgeon’s instructions at home during the first few weeks following surgery.
- Wound Care- You will have either absorbable sutures (stitches) and skin glue or staples along your incision. You will not need to remove your absorbable sutures, if staples were used they will be removed several weeks after surgery. You will need to avoid soaking the wound in water until it has sealed and dried thoroughly. You can continue bandaging the wound to prevent irritation from clothing or support stockings.
- Diet- Loss of appetite is common for a few weeks after surgery. It is important to have a balanced diet to help your wound heal and to restore muscle strength.
- Activity- A critical component of your recovery at home is exercise, especially in the first few weeks after surgery. Most normal daily living activities can be resumed within 2-4 weeks after surgery. Pain with activity and at night is common initially.
2 Weeks After Surgery
You should be able to move around more freely and experience less pain. Your daily routine should include the exercises that your physical therapist has given you. Walking and standing for 10 minutes or more, bathing, and dressing should be easier. Your knee may actually be strong enough to not need your walker anymore. People progress to a cane or no assistive device at all by 2-3 weeks.
4-6 Weeks After Surgery
You should notice a dramatic improvement in your knee if you’ve stayed on your physical therapy exercises and rehabilitation schedule. Swelling and inflammation should also be reduced by now. Increasing your knee strength and range of motion is the goal at this point of your recovery. Some people may start driving within this period, but it is best to consult your doctor beforehand. Traveling before 6 weeks post surgery can increase your risk of a blood clot due to prolonged sitting, so it is best to wait until after 6 weeks. If you can not wait to travel, your doctor may recommend blood thinners be used.
7-11 Weeks After Surgery
Physical therapy will continue for about 12 weeks after your surgery. Your physical therapist will most likely modify your exercises as your knee improves. These may include, but are not limited to bicycling on a stationary bike, toe and heel raises, mini squats, hip abductions, leg balances, and step-ups. This time of your recovery is very important! Commiting to your rehabilitation will determine how fast you can return to your normal lifestyle. The pain and stiffness should be significantly reduced and you may be able to walk without an assistive device for a couple of blocks.
12 Weeks After Surgery
At 12 weeks, you will still need to do your exercises but also avoid high impact activities to avoid damaging your knee or the tissues that surround it. Many patients are beginning to enjoy activities such as golf, dancing, and bicycling. Your pain may be minimal or gone completely at this point.
What’s Expected in Physical Therapy After a Knee Replacement Surgery?
Your physical therapist will teach you exercises to target your specific limitations. We know that it can be difficult to get your knee moving after surgery, however it is very important. The two most common exercises prescribed are quad sets and heel slides. These exercises work on straightening and bending your knee, and are crucial to a full recovery.
- Quad sets: Work on strengthening your quadriceps muscle. This muscle is responsible for straightening the knee. It also plays a large role in your single leg balance, squatting, and climbing stairs. These are performed by lying on your back, sitting with your legs stretched out in front of you, or standing with or without a towel roll under your knee or ankle. Your hold times and repetitions are based on your individual needs.
- Heel slides: Work on bending the knee. Restoring normal mobility for squatting, climbing stairs, etc. is important. Heel slides can be performed either lying on your back or sitting and with or without a strap or towel. Again, your hold times and repetitions will depend on your individual needs.
