What Are the Risks of Delaying My Knee Replacement Surgery?

Patients delay knee replacement surgery for a number of reasons, mostly out of fear and misinformation. "Most patients delay unnecessarily for several perceptual reasons: fear of the unknown, fear of surgery, fear of 'losing' a body part, fear of the post-op surgery pain, fear that they will end up worse than they started."

The risks related to delaying knee replacement surgery often involve the deterioration of the joint, increased pain, and lack of mobility. Depending on the severity of the joint disease, a surgeon may attempt several less invasive, non-surgical methods first (including glucosamine, anti-inflammatory medications, cortisone injections, and physical therapy). If none of these methods appear to be working or if the patient has become sedentary due to joint pain, a surgeon may recommend knee replacement surgery. For many of the reasons listed above, patients sometimes consciously delay their knee replacement surgery, which can have some of these risks:

• risk of deformities developing inside and outside the joint
• risk of muscles, ligaments and other structures becoming weak and losing function increased pain / inability to manage pain
• increased disability/lack of mobility
• difficulty with normal activities of daily living

When a knee replacement surgery is delayed, there are also several risks that arise with regard to the surgical procedure. For example, the risk of deformities due to postponement tends to make knee replacement surgery a more complicated process. The surgery may then take longer and require a longer amount of time under anesthesia. In addition, postponement can limit knee replacement options. For example, joint disease that is spotted early on and treated may only require a "unicompartmental knee joint on the medial side." But after delay, destruction to the knee joint becomes so severe that a total knee replacement (a more complex surgery) is required - with possibly even the addition of a knee cap ("patellar") resurfacing. Recent studies have shown that timing does make a difference in joint replacement surgery. if surgery is performed early it may be more successful. When a patient is relatively healthy and gets a knee replacement, she is more likely to recover sooner and with less complications. Knee replacement surgery is not recommended for everyone, and we do suggest that you visit your doctor and find out what is best for you. But if you are a knee replacement surgery candidate, postponement can leac to a number of unnecessary and avoidable issues.
