What is a Partial Knee Replacement?

Partial knee replacements (unicompartmental knee replacements) are a type of knee replacement that only replaces the arthritic part of the knee. Patients with a partial knee recover from their surgery faster and are more likely to have a knee that feels like a normal knee compared to a total knee replacement.

Partial knee replacements only replace the part of the knee that is arthritic. In a total knee replacement, there are two ligaments that are normally removed – the anterior cruciate ligament and the posterior cruciate ligaments. In addition, partial knee replacements allow you to keep the good cartilage that is in your knee. Unlike a traditional knee replacement, partial knees are considered resurfacing surgery.

膝关节部分置换术有哪些类型？

部分膝关节有几种不同的类型。
膝关节内侧被视为 “内侧室”。
膝关节外侧为 “外侧室”。
膝盖下方的部分称为 “髌股关节室”。
可以通过外侧、内侧或髌股关节置换术分别独立置换这些腔室。
有时可以置换两个隔间，即 “双隔间置换术”。

膝关节部分置换手术适合你吗？

Partial knee replacements are a good option for you if you have severe knee pain that does not improve with conservative treatment. In addition, you should have arthritis isolated to only location. If you have arthritis in more than one compartment, having a partial knee replacement may lead to an early revision surgery.  You should consider surgery when you have problems in certain areas of your life secondary to your knee pain such as:

日常生活活动有问题：做家务或买菜

进行你喜欢的活动：散步、打高尔夫球、骑自行车或园艺

职业活动：无法履行工作职能

享受天伦之乐：与孙辈玩耍或与配偶一起活动时的疼痛

我有关节炎，但我被告知不适合做膝关节部分置换术

If you have severe deformity, loss of ACL function, inflammatory arthritis, or severe osteoarthritis, a partial knee replacement may lead to a high chance of failure of your partial knee replacement and likely future revision knee replacement.

益处

Patients who undergo a partial knee replacement have:

切口较小

减少疼痛

减少失血

手术后恢复更快

缺点

A partial knee replacement only resurfaces part of your knee. Some patients can have excess pressure placed on the un-resurfaced portion of their knee. This increase in pressure can lead to degenerative wear in the areas of the knee that was not replaced. This increase in wear leads to further arthritis of the joint. The best way to prevent this is by better placement of components using robotic-assistance. Talk with Dr. Morton to see if you are a candidate for a partial knee replacement. Dr. Morton can help explain why you might not be a good candidate for a partial knee replacement.

膝关节部分置换术后的恢复

After your partial knee replacement, you will begin walking on the day of surgery after you recover from anesthesia. Many patients are able to go home after surgery. Your physical therapist will assist you in beginning to walk again. Often you will have pain while you are recovering and you will have to work on recovering your muscle strength. You may require a walker or a cane to get around for the first couple of months after surgery. During your surgery, we provide multiple modes of anesthesia to reduce your pain including nerve blocks, intra-operative injections, and a low-narcotic pain medication regimen.

目标

Many patients are able to walk normally 2 – 3 weeks after surgery. Most patients are able to return to many of your activities by 6 weeks after surgery.  Over the course of a year, you will continuously gain benefits from your knee replacement. Sometimes it may take 2 years to get the full benefit of your new knee.

The goal of your partial knee replacement is to give you the best opportunity to have a normal feeling knee that will allow you to return to activities that you enjoy such as long walks, dancing, golfing, gardening, and biking. A partial knee replacement has been performed for many years with an excellent track record for improving quality of life, returning patients to their independence, and reducing pain.

抱有现实的期望

Unfortunately, a knee replacement may not solve all of your knee problems. More than 90% of patients who undergo a partial knee replacement have a dramatic improvement in their knee pain. This gives patients the ability to return to a normal lifestyle and perform everyday activities. Over time, the plastic component in your partial knee replacement can wear out. Increased weight, or high levels of impact activity may speed up this wear and cause problems with your knee. The American Association of Hip and Knee Surgeons advise patients to avoid high impact activities such as running, jogging, jumping, or other high-impact activities with a knee replacement.

风险

Despite the technological and medical advancements that we have made, there are still risks with partial knee replacement surgery. Risks include:

感染

失血量

血凝块

非关节炎部位的磨损

断裂

种植体松动

膝关节僵硬

神经或血管损伤
