In some rare cases, a surgeon may not recommend surgery because the potential risks outweigh the benefits. If a person has a high risk of complications, the surgeon will discuss this with them during the evaluation process. Of these, 29.8 percent are due to the joint coming loose, 14.8 percent due to infection, and 9.5 percent due to pain. Revision is when a person needs a second knee replacement at some point in time after their initial operation.Įxperts estimate that 5 percent of people will need a revision within the first 10 years. Statistics vary, but according to one estimate, 20 percent of people may continue to experience persistent pain despite a well-performed operation. Pain usually reduces as a result of knee surgery. The best way to avoid stiffness is to follow the exercise regimen that your healthcare providers recommend. It occurs when scar tissue forms in the knee and limits movement of the new joint. Stiffness, or arthrofibrosis, is one of the more common complications after knee replacement surgery. Loosening of the knee joint can occur over time.Īccording to research, osteolysis is the most common reason for long-term failure of a total knee replacement, requiring a second (revision) operation. Osteolysis (destruction of bone) happens when microscopic plastic particles from the knee implant cause inflammation. Of these, 0.9 percent had DVT and 0.3 percent had PE, a more serious condition. One study found that 1.2 percent of people were hospitalized with blood clots within 90 days of total knee replacement surgery. If a DVT breaks off and travels to the lungs, it results in a pulmonary embolism (PE), which can be life threatening. These are called deep vein thromboses (DVTs). Blood clots and DVTīlood clots can develop after surgery. Risk factors for infection include diabetes, obesity, and older age. Newer practices of giving antibiotics before and during the operation have reduced the risk dramatically to around 1 to 2 percent. In 1981, one expert estimated that the infection rate for knee surgery was 9.1 percent. According to the AAOS, fewer than 2 percent of people experience severe complications, such as an infection or a blood clot. Knee replacement surgery is relatively safe and effective for most people.
