Prior to transfemoral surgery, your physical therapist may:
- Prescribe exercises for preoperative conditioning to improve your upper and lower extremity strength and flexibility
- Teach you how to walk with a walker or crutches
- Educate you about what to expect after the procedure
Immediately After Surgery
You should expect to stay in the hospital for approximately 5 to 14 days following your surgery. Your wound will be bandaged, and you may also have a drain at the surgery site. Pain will be managed with medication.
Physical therapy will begin soon after surgery when your condition is stable and the doctor clears you for rehabilitation. A physical therapist will review your medical and surgical history, and visit you at your bedside. Your first 2 to 3 days of treatment may include:
- Gentle stretching and range-of-motion exercises
- Learning to roll in bed, sit on the side of the bed, and move safely to a chair
- Learning how to position your surgical limb to prevent contractures [the inability to straighten the knee joint fully caused by keeping the limb bent too much]
When you are medically stable, the physical therapist will help you learn to move about in a wheelchair, and stand and walk with an assistive device like a walker.
Prevention of Contractures
A contracture is the development of soft-tissue tightness that limits joint motion. The condition occurs when muscles and soft tissues become stiff from lack of movement. For example, if a person with a transfemoral amputation sits in the same position for long periods of time, the hip muscles may adapt to the new position and become stiff. Lying in bed with a pillow between your legs may cause a contracture with the leg positioned too far out to the side, if this position is repeated over sustained periods of time.
Contractures can become permanent if not addressed following surgery, throughout recovery, and after rehabilitation is completed. Contractures can make it difficult to wear your prosthesis and make walking more difficult, increasing the need for an assistive device, such as a walker.
Your physical therapist will help you maintain normal posture and range of motion at your hip. Your physical therapist will show you how to position your limb to avoid development of a contracture, and teach you stretching and positioning exercises to maintain normal range of motion.
Compression to Address Swelling
It is normal to experience postoperative swelling. Your physical therapist will help you maintain compression on your residual limb to protect it, reduce and control swelling, and help it heal. Compression can be accomplished by:
- Wrapping the limb with elastic bandages.
- Wearing an elastic shrinker sock.
These methods also help shape the limb to prepare it for fitting the prosthetic leg.
In some cases, a rigid dressing or a plaster cast may be used instead of elastic bandages. An immediate postoperative prosthesis made with plaster or plastic may be applied. The method chosen depends on each person's unique condition. Your physical therapist will help monitor the fit of these devices and instruct you in their use.
Pain Management
Your physical therapist will help with pain management in a variety of ways, including:
- The use of electrical stimulation and TENS [transcutaneous electrical nerve stimulation] for pain modification. Gentle electrical stimulation of the skin helps relieve pain by blocking nerve signals from underlying pain receptors.
- Performing manual therapy, including massage and joint manipulation to improve circulation and joint motion.
- Providing residual limb management, including skin care and proper stump sock use.
- Desensitization to help modify how sensitive an area is to clothing pressure or touch. Desensitization involves stroking the skin with different types of touch to help reduce or eliminate the sensitivity reaction to the stimulus.
See the Physical Therapy Guide to Phantom Limb Pain for more information about amputation pain.
Functional Recovery
Your physical therapist will work with the prosthetist to prescribe the best prosthesis for your life situation and activity goals. An above-knee prosthesis includes a socket, knee joint, ankle joint, and foot components. You will receive a temporary prosthesis at first while your residual limb continues to heal and shrink/shape over several months of healing. The prosthesis will be modified to fit as needed over this time.
Increasing independent function. After you move from acute care to rehabilitation, you will learn to function more independently. Your physical therapist will help you master wheelchair mobility and walking with an assistive device, such as crutches or a walker. Your physical therapist will also teach you the skills you need for successful use of your new prosthetic limb. You will learn how to care for your residual limb with skin checks and hygiene, and continue contracture prevention with exercise and positioning.
Learning prosthesis use and care. Your physical therapist will teach you how to put your new prosthesis on and take it off, and how to manage a good fit with the socket type you receive. Your physical therapist will help you to gradually build up tolerance for wearing your prosthesis for increasingly longer times, while protecting the skin integrity of your residual limb. You will continue to use a wheelchair for getting around, even after you get your permanent prosthesis, for the times when you are not wearing the limb.
Prosthetic training is a process that can last up to a full year. You will begin when the physician clears you for weight-bearing on the prosthesis. Your physical therapist will help you learn to stand, balance, and walk with the prosthetic limb. Most likely you will begin walking using parallel bars, then progress to a walker, and later, as you get stronger, you may progress to using a cane before walking independently without any assistance. You will also need to continue strengthening and stretching exercises to achieve your fullest potential for a return to many of the activities you performed before your amputation.
