With more than 600,000 surgeries performed in the U.S. 一年又一年 估计4.700万美国人生活在植入物中， 膝关节置换术非常普遍. 预计这个数字只会继续增长. 事实上， 威尼斯人官网研究和质量机构 estimates that by 2030 the number of knee replacements each year will grow to over 3 million – due in large part to the aging Baby Boomer 人口. 在威尼斯人官网医院 联合修复研究所在博士之间. Dearborn and myself, we perform more than 900 total knee replacements each year, or a little over half our total annual joint surgery volume.
People are living longer and expecting to maintain their quality of life as they age, which includes maintaining mobility, independence and employment. Hip and knee replacement can help them achieve that.
Before you decide to undergo surgery, here are some frequently asked questions 关于膝关节置换术.
全膝关节置换术涉及到什么?
At the IJRR, we specialize in both traditional and minimally invasive knee 置换手术.
In traditional knee replacement, an 8 to 10-inch incision is made on the front of the knee to expose the damaged area of your joint. 在这 process the quadricepts tendon is cut and the kneecap is dislocated, allowing the surgeon to cut away damaged bone and cartilage and replace them with 假体关节. Due to incision length, muscle dissection and other tissue trauma occurring during this procedure, the recovery process can 长达数月之久.
However, some patients may be candidates for minimally invasive knee replacement. As the name implies, a smaller incision (only about 4” long) is made, and, more importantly, the muscle isn’t cut and the kneecap 是移位而不是脱臼. 对于正在接受手术的病人 the procedure, there’s less trauma, less pain, shorter hospital 留下，更快的恢复.
我真的需要这个手术吗?
As an elective surgery, the decision to undergo knee replacement is entirely 由你决定. If knee pain is affecting your ability to go about daily activities like working or walking the dog, it may be the best option for maintaining 你的生活质量.
Of course, there are other routes you can explore before deciding. 物理 therapy and exercise can help strengthen the muscles around the knee, 稳定关节. Your orthopedic surgeon may recommend other procedures or treatments to try, like steroid injections or less invasive surgical approaches, before resorting to total knee replacement.
But, ultimately, it all depends on what you want to be able to physically 完成你现在和未来的生活.
疼痛怎么办？?
在这 procedure, you will be under regional anesthesia. 虽然它的 not without its risks, complications from anesthesia are extremely rare. Epidural and spinal anesthesia effectively and safely numb the waist down, 这样就可以避免全身麻醉.
After surgery, you may experience some pain, but that generally lasts less 超过一周. At the IJRR, we practice multi-modal pain management. 什么 that means is we use a variety of different medications in smaller doses to optimize pain based on an individual’s tolerance. 这可以帮助 us avoid using narcotics and opioids and helps patients recover more quickly 而且副作用更少.
So how long can you expect to experience post-surgical pain or discomfort? While there’s no way to predict results, it can be affected by your willingness to perform the physical therapy and lifestyle modifications 必须优化手术后的恢复.
手术后我能期待什么?
Immediately after the operation is complete, patients spend 2-3 hours in 恢复室. At the IJRR, patients are then transferred to the Center for Joint Replacement building, where they’re placed in the care of nurses and therapists who specialize in joint replacement patients. After 2-3 hours, you’ll regularly meet with physical therapists to work on stretching exercises and techniques for performing routine 独立的任务. Single knee patients are usually up and walking (with a walker or crutches) the day of surgery and discharged that same day 或者下一个.
After discharge, regular occupational or physical therapy will continue 接下来的几个星期. The exact length depends on your healing progress, 操作方法，及关节功能. 你应该能够表演 basic activities like assisted walking and bathing within a week, but you should always consult your physical therapist before introducing exercise or other physical activities during this rehabilitation period.
这个替换关节可以使用多久?
In general, the need to perform a revision surgery occurs at a rate of 每年不到1%. 事实上，研究表明，全膝关节 replacements will last for 20 years or longer in 80 to 90 percent of cases. 种植体失败的常见原因包括：
Additionally, the plastic joint liners, while durable, can wear over time, but can be removed and changed without disturbing metal components or bone-prosthesis固定.
While a worn knee joint may not affect how long you live, it can affect 你充实生活的能力. 慢性疼痛和活动能力丧失 can affect your ability to work, play, and even perform simple daily tasks 比如洗澡或步行去你的车. 如果骨关节炎或损伤是不利的 affecting 你的生活质量, knee replacement may be an option for you.
