How Long Do You Stay in the Hospital After Knee Replacement?

Total knee replacement surgery is a common orthopedic procedure designed to alleviate pain and restore function in a severely damaged knee joint. It involves replacing worn or injured parts of the knee with artificial components, typically made from metal and plastic. The primary goal is to improve mobility and quality of life, helping individuals regain the ability to walk, climb stairs, and perform routine movements with greater ease.

Typical Hospital Stay Duration

The duration of a hospital stay following total knee replacement has significantly decreased. Many individuals now anticipate a hospital stay ranging from one to three days. Some patients may even be candidates for same-day discharge, reflecting advancements in surgical techniques and pain management protocols.

This reduced time in the hospital does not typically increase the rate of complications or readmissions. Patients are encouraged to mobilize early after surgery, which contributes to quicker discharge times.

Factors Influencing Your Stay

Several factors influence how long an individual remains in the hospital after total knee replacement. A patient’s overall health before surgery plays an important role; pre-existing conditions like diabetes, hypertension, or heart and lung disease can lead to longer stays. Age is another consideration, as older patients, particularly those over 75, may have an increased length of stay.

A patient’s mobility prior to surgery, including the use of walking aids, also affects the recovery timeline. Body mass index (BMI) is a factor, with some studies indicating a correlation between lower BMI and increased length of stay. Intraoperative factors, such as surgery duration and blood loss, can also influence the immediate post-operative period.

Post-operative progress in physical therapy is a key factor for discharge. The ability to mobilize early, achieve specific knee flexion goals, and effectively manage pain are important milestones. Complications like infection, blood clots, or the need for a blood transfusion can extend the hospital stay. Social support available at home for post-discharge care can also contribute to a shorter inpatient period.

Discharge Criteria and Post-Hospital Planning

To be discharged from the hospital after knee replacement surgery, patients must meet specific criteria to ensure they can safely continue recovery at home or in another care setting. These typically include having pain adequately controlled with oral medications and demonstrating the ability to move independently, such as getting in and out of bed.

Functional milestones like walking with an assistive device, such as a walker or crutches, are also assessed. If the patient’s home environment includes stairs, they may need to show they can navigate them safely before leaving the hospital. Patients also need to be able to perform basic self-care activities.

Post-hospital planning is an important part of the recovery process, beginning even before surgery. Options for continued care include returning home with support from home health services and outpatient physical therapy. For some, a transition to an inpatient rehabilitation facility may be arranged if their recovery requires more intensive, supervised care.

Preparing for a Smoother Recovery

Preparation before knee replacement surgery can contribute to a smoother and potentially shorter recovery. Engaging in prehabilitation, which involves physical therapy and exercise, can enhance physical fitness and mental readiness. This approach strengthens muscles around the knee, improves cardiovascular health, and increases overall mobility.

Optimizing general health is another important step. This includes stopping smoking at least six weeks prior to surgery, as nicotine can delay healing. Managing weight through healthy eating and exercise can reduce stress on the knee and improve recovery. For those with conditions like diabetes, ensuring blood sugar levels are well-controlled before and after surgery is also beneficial.

Preparing the home environment can also facilitate recovery. This involves arranging furniture to create clear pathways for walking aids and ensuring frequently used items are easily accessible. Arranging for assistance from family or friends for daily tasks and transportation in the initial weeks post-surgery is advisable. Active participation in post-operative physical therapy, both in the hospital and at home, is important for regaining strength and mobility.
