There are four basic steps to a knee replacement procedure: (Left) Severe osteoarthritis. The motion of your knee replacement after surgery can be predicted by the range of motion you have in your knee before surgery. Dressing is required for proper wound management. Surgeons have performed knee replacements for over three decades generally with excellent results; most reports have ten-year success rates in excess of 90 percent. Individuals with rheumatoid arthritis and related conditions need to be evaluated and followed by a physician who specializes in those kinds of treatments called a rheumatologist. In some patients the symptoms wax and wane causing good days and bad days. Knee arthritis does not usually improve on its own. The warning signs of possible blood clots in your leg include: Warning signs of pulmonary embolism. The damaged cartilage surfaces at the ends of the femur and tibia are removed along with a small amount of underlying bone. Your new knee may activate metal detectors required for security in airports and some buildings. This broad category includes a wide variety of diagnoses including rheumatoid arthritis, lupus, gout and many others. When a knee is replaced, a nylon stitch is typically used. Joint replacement surgery is a safe and effective procedure to relieve pain, correct leg deformity, and help you resume normal activities. Next, specialized alignment rods and cutting jigs are used to remove enough bone from the end of the femur (thigh bone), the top of the tibia (shin bone), and the underside of the patella (kneecap) to allow placement of the joint replacement implants. Each knee has two rings of cartilage called "menisci" (this is the plural form of "meniscus"). Let your dentist know that you have a knee replacement. This is done to re-orient the loads that occur with normal walking and running so that these loads pass through a non-arthritic portion of the knee. You should have major dental procedures (such as tooth extractions and periodontal work) completed before total knee replacement surgery in order to reduce the risk of infection. At first physical therapy includes range-of-motion exercises and gait training (supervised walking with an assistive device like a cane crutches or walker). Pain relief and function enhancement are the goals of surgery. Several modifications can make your home easier to navigate during your recovery. Magnetic resonance imaging can reveal peri-prosthetic lucencies that a plain film may not show. Complications with the knee, such as a knee joint infection, account for less than 2% of cases. Broadly speaking there are two types of knee replacements: Both have long track records and good clinical results in this country and in Europe. Bone spurs are a common feature of this form of arthritis. Regular range of motion exercises and weight bearing activity are important in maintaining muscle strength and overall aerobic (heart and lung) capacity. Radionuclide uptake is influenced by blood flow, osteoclastic activity, and sympathetic tone in addition to blood flow. These bacteria can lodge around your knee replacement and cause an infection. Warning signs of blood clots. One patient with a complete tear was treated . Finally, the bone is cleaned using saline solution and the joint replacement components are cemented into place using polymethylmethacrylate bone cement. AAOS does not endorse any treatments, procedures, products, or physicians referenced herein. During the operation, the surgeon will make incisions on the front and back of the knee and then carefully remove the damaged bone and cartilage. Total knee replacement, or total knee arthroplasty, is a surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses). In this stage, the wound clots through a so-called clotting cascade. Anyone seeking specific orthopaedic advice or assistance should consult his or her orthopaedic surgeon, or locate one in your area through the AAOS Find an Orthopaedist program on this website. In addition, the patients own high level of motivation and enthusiasm for recovery are very important elements in determining the ultimate outcome. They are cheap and easy to use. Eleven patients had a complete tear, and twenty-three had a partial tear. People who feel they need narcotics to achieve pain control should consider seeing a joint replacement surgeon (an orthopedic surgeon with experience in knee replacements) to see whether surgery is a better option. Because of its occlusive nature, some advanced wound dressings have been shown to reduce blistering. Unless the type dissolve during the wound healing process, stitches or staples will be used to close the wound, and you will most likely need to remove it after 10-12 days. It is preferable to this surgery because complications from a more complex operation may outweigh the advantages you receive. If X-rays dont show very much arthritis and the surgeon suspects (or has identified by MRI) a torn meniscus, knee arthroscopy may be a good choice. After the epidural is removed pain pills usually provide satisfactory pain control. If you have had knee replacement surgery, you may damage your new knee implant if you fall on it. Other treatment options including medications, injections, physical therapy, or other types of surgery will also be considered and discussed.

Among the causes of these failures is metal hypersensitivity. Patients who are considering knee replacements should ask their surgeon whether minimally-invasive partial knee replacement (mini knee) is right for them. TJA has used hydrofiber dressings, such as Aquacel, in the past. The use of staples or sutures to reconstruct the skin is still a contentious topic that could have a significant impact on both patient safety and surgical outcomes. The pictures can be helpful in understanding the procedure and what to expect during surgery. Knee replacement is a surgical technique that has many variables. Recurrent haemarthrosis is uncommon in people who have had TKR, with an incidence of between 3.3% and 1.6% reported. Hip ABD/Adduction. Surgeons with this level of experience have been shown to have fewer complications and better results than surgeons who havent done as many knee replacements. It is important to distinguish broadly between two types of arthritis: inflammatory arthritis (including rheumatoid arthritis, lupus and others) and non-inflammatory arthritis (such as osteoarthritis). Arthritis is often progressive and symptoms typically get worse over time. Some pain with activity and at night is common for several weeks after surgery.

X-rays with the patient standing allow your physician to view the way the knee joint functions under load (i.e. So, choosing a fellowship-trained and experienced knee replacement surgeon is important. To decide whether a knee replacement is right for you, a surgeon checks your knee's range of motion, stability . Access to an online platform allows patients to participate in a personalized rehabilitation program that has been tailored to their recovery needs. Your orthopaedic surgeon will review the results of your evaluation with you and discuss whether total knee replacement is the best method to relieve your pain and improve your function. In a healthy knee, these structures work together to ensure smooth, natural function and movement. Any infection in your body can spread to your joint replacement. For patients who are unable to attend outpatient physical therapy, home physical therapy is arranged. This is normal. It may even occur years later. A randomized trial evaluating the cost and time benefits of scalp laceration closure. When TJA has finished, dressings made of hydrocolloid and hygroscopy should be used because they have high absorptive capacity and permeability and can withstand exudate production. The presence of infected TKRs is strongly influenced by the presence of indium leukocytes scan for infection. These researchers argue that TKA should be performed between the ages of 70 and 80 due to the high risk of heart failure in this age group. Despite this success, it produces 20% unsatisfactory results. There is good evidence that the experience of the surgeon correlates with outcome in total knee replacement surgery.

If you have severe pain, consult with your surgeon as soon as possible. In the video below, orthopedic surgeon Dr. Seth Leopold demonstrates minimally invasive knee replacement surgery and discusses the benefits to patients. Watch a Video: Minimally-Invasive Joint Replacement. Regardless of whether a traditional total knee replacement or a minimally-invasive partial knee replacement (mini knee) is performed the goals and possible benefits are the same: relief of pain and restoration of function. These differences often diminish with time and most patients find them to be tolerable when compared with the pain and limited function they experienced prior to surgery. Position the metal implants. An important factor in deciding whether to have total knee replacement surgery is understanding what the procedure can and cannot do. A total knee replacement typically takes 12 weeks to complete. These are recommendations only and may not apply to every case. Activity limitations due to pain are the hallmarks of this disease. Your new knee may cause metal detectors in some buildings and airports to detect metal. Furthermore, the study found that patients who are well-versed in their medical histories and are prepared for surgery have a better chance of success with a joint replacement. Thats why it doesnt work well if more than one compartment of the knee is involved--in those patients there is no good place through which the load can be redistributed. Exudate is absorbed by these dressings and forms a gel, which helps to increase dressing permeability. It is not uncommon for a significant amount of time to go misdiagnosed with persistent pain after total knee replacement. In the J. Pediatr. This device is similar to the one that is used to help women deliver babies more comfortably. As a result of the surgery, you will need to wear an ACE bandage to provide support and reduce swelling. Narcotics are designed for people with short-term pain (like after a car accident or surgery) or for people with chronic pain who are not surgical candidates. So-called non-inflammatory conditions including osteoarthritis (sometimes called degenerative joint disease) also sometimes respond to oral medications (either painkillers like Tylenol or non-steroidal anti-inflammatory drugs like aspirin, ibuprofen, or celebrex) but in many cases symptoms persist despite the use of these medications. Most patients take some narcotic pain medication for between 2 and 6 weeks after surgery. TegadermTM is used in Aquacel, which results in a wound with no complications and less blistering (2.4%) than Cutiplast. Seven patients with a partial tear were treated nonoperatively, and all had a satisfactory outcome. Obesity, Weight Loss, and Joint Replacement Surgery, Preparing for Surgery: Health Condition Checklist. Proper sizing and alignment of the implants, as well as balancing of the knee ligaments, all are critical for normal post-operative function and good pain relief. Remember that scars can take a long time to heal and that they can be managed in a variety of ways. Improvement of knee motion is a goal of total knee replacement, but restoration of full motion is uncommon. To reduce the risk of infection, major dental procedures (such as tooth extractions and periodontal work) should be completed before your total knee replacement surgery. It is possible to catch a lateral femoral condylar osteophyte that is still attached to the popliteus tendon. Your orthopaedic surgeon will discuss with you whether you need to take preventive antibiotics before dental procedures. Although you will be able to walk with a cane, crutches, or a walker soon after surgery, you will need help for several weeks with such tasks as cooking, shopping, bathing, and doing laundry.

Total knee arthroplasty (TKA) or total knee replacement (TKR) is a common orthopaedic surgery that involves replacing the articular surfaces (femoral condyles and tibial plateau) of the knee joint with smooth metal and highly cross-linked polyethylene plastic. Frequently the stiffness from arthritis is also relieved by the surgery. The knee joint has three compartments that can be involved with arthritis (see figure 1). -Foam dressings: Foam dressings are similar to hydrocolloid dressings but are less expensive. The author has read and agreed to the final manuscript. Many studies show that 90-95 percent of total knee replacements are still functioning well 10 years after surgery. Hydrofiber dressing (Aquacel) and a basic central pad (Mepore) have been shown to be both more cost effective in cost analysis studies. Patients with inflammatory arthritis of the knee usually have joint damage in all three compartments and therefore are not good candidates for partial knee replacement. Minimally-invasive partial knee replacement (mini knee) is the topic of another article on this website. Most patients obtain and keep at least 90 degrees of motion (bending the knee to a right angle) by the second week after surgery and most patients ultimately get more than 110 degrees of knee motion. There are few pre-existing health conditions that should disqualify a candidate for minimally invasive knee replacement who has only limited or moderate deformity, maintains a healthy weight, and does not have any known deformity problems. Brandon Callahan, MD is a board-certified orthopedic physician with a decade of experience in providing comprehensive orthopedic care to patients with musculoskeletal injuries and disorders. Physical therapy and muscle building will make stair climbing easier. Very often the distance one can walk will improve as well because of diminished pain and stiffness. Realistic activities following total knee replacement include unlimited walking, swimming, golf, driving, light hiking, biking, ballroom dancing, and other low-impact sports. In this procedure, the surgeon will be able to replace the knee joint with a new one. (Left) An x-ray of a severely arthritic knee. Most people walk using crutches or a walker for 3-4 weeks then use a cane for about 2-3 more weeks. This is a natural part of the healing process. The causes of painful knee replacement are broadly classified as intrinsic and extrinsic (see Table I). The surgical procedure usually takes from 1 to 2 hours. Sometimes patients with knee pain don't have arthritis at all. Wound dressing and wound management after hip, knee, and shoulder arthroplasty are covered in a number of articles. Although there are many types of arthritis, most knee pain is caused by just three types: osteoarthritis, rheumatoid arthritis, and posttraumatic arthritis. Our team of experts, doctors, and orthopedic specialists are here to share their knowledge and experience with you in order to help you make informed decisions about your health and well-being.

The majority of total knee replacement patients are over the age of 50. Turned out it was about 1/4" long and the bottom was dissolved; the top part that was sticking out had not dissolved. The surgeon will then begin work on the bone. Two to three therapy sessions per week are average for this procedure. The menisci work similarly to shock absorbers in a car. It is important to learn as much as possible about the condition and the treatment options that are available before deciding whether--or how--to have a knee replacement done. Following TJA, a type of foam dressing is used to aid in wound healing. Tenderness or redness above or below your knee, New or increasing swelling in your calf, ankle, and foot, Persistent fever (higher than 100F orally), Increasing redness, tenderness, or swelling of the knee wound, Increasing knee pain with both activity and rest. Studies show that strengthening your muscles before your knee replacement surgery can help you to recover more quickly and achieve better outcomes. The large majority walk without a limp and most dont require a cane, even if they used one before the surgery. Excellent non-surgical treatments (including many new and effective drugs) are available for these patients; those treatments can delay (or avoid) the need for surgery and also help prevent the disease from affecting other joints. Buried or capular closures are typically performed using either interrupted knotted sutures or continuous barbed sutures. In this study, the staple skin closure and the suture skin closure were compared in patients undergoing primary total knee arthroplasty. Again, these steps are complex and considerable experience in total knee replacement is required in order to make sure they are done reliably, case after case. Blood clots in the leg veins are one of the most common complications of knee replacement surgery. It is therefore important that the surgeon performing the technique be not just a good orthopedic surgeon, but a specialist in knee replacement surgery. An orthopedic surgeon will begin the evaluation with a thorough history and physical exam. In general, the incision should be covered by a bandage for at least two to three weeks following surgery. This surgery may be considered for someone who has severe arthritis or a severe knee injury. Patients who prefer not to have inpatient rehabilitation may spend an extra day or two in the hospital before discharge to home. Aggressive rehabilitation is desirable following this procedure and a high level of patient motivation is important in order to get the best possible result. This is needed to make sure you are healthy enough to have the surgery and complete the recovery process. The wound is closed with internal stitches to keep all the ligaments and muscles securely together, and sutures or special tape on the skin. In many cases, patients will experience mild to moderate pain behind their knee after a total knee replacement, indicating that the tissues surrounding the knee are still healing. Some surgeons believe that a CPM machine decreases leg swelling by elevating your leg and improves your blood circulation by moving the muscles of your leg, but there is no evidence that these machines improve outcomes. Patients with a good epidural can expect to walk with crutches or a walker and to take the knee through a near-full range of motion starting on the day after surgery. Prior to surgery an orthopedic surgeon may offer medications (either non-steroidal anti-inflammatory medications or analgesics like acetaminophen which is sold under the name Tylenol) knee injections or exercises. The success of your surgery will depend largely on how well you follow your orthopaedic surgeon's instructions at home during the first few weeks after surgery. If you feel a clicking or snapping sensation in the posterolateral aspect of your knee, it could indicate impingement. However, there is no evidence to suggest that wound healing efficacy or patient satisfaction is the same in the same knee. The surgery to replace your knees is critical for your overall health. If not treated promptly knee infections can cause rapid destruction of the joint. Oral pain medications help this process in the weeks following the surgery. Three to five recovery days are typically required in the hospital following surgery, with a recovery time of approximately 12 weeks. The large majority of patients report substantial or complete relief of their arthritic symptoms once they have recovered from a total knee replacement. Many patients with chronic medical conditions, like heart disease, may also be evaluated by a specialist, such as a cardiologist, before the surgery. As a result of their use and overdose, prescription drug addiction and overdose are both critical public health issues in the United States. Your surgerys success will be determined primarily by how well you follow your orthopaedic surgeons instructions at home. The cause of pain associated with activity, such as a loose component, instability, or impingement, is likely to be a loose component. After the wound has been treated, a dissolvable stitch is placed under the skin to close it. Bed supported knee bends: Lying down, slide your foot back toward your buttock, keeping your heel on the bed. Arthritis patients who develop such infections would notice a significant worsening in their pain as well as some of the other symptoms listed above. It is most suitable for middle-aged and older people who have arthritis in more than one compartment of the knee and who do not intend to return to high-impact athletics or heavy labor. Again the overall likelihood of a severe complication is typically less than 5 percent when such steps are taken. Most patients who undergo total knee replacement are age 50 to 80, but orthopaedic surgeons evaluate patients individually. Generally speaking patients with inflammatory arthritis (like rheumatoid arthritis or lupus) and patients with diffuse arthritis all throughout the knee should not receive partial knee replacements. Repeat 10 times (1 set). Some loss of appetite is common for several weeks after surgery. It is unknown how many patients who have had knee replacement continue to experience pain. Because there is no need for the surgeon to go through the muscle, this procedure is minimally invasive.
