Postoperative knee swelling?


Hello! It has been a month since you underwent arthroscopic distal femoral osteotomy and partial meniscectomy.
You have been consistently doing bending and leg lifting rehabilitation exercises, as well as applying ice, but you have noticed significant swelling in your knee.
Is swelling a normal phenomenon? How long after the surgery can I walk normally on my own? Thank you!

Swelling is a normal phenomenon, and you can try to walk after about six weeks; it will take three months to return to normal.

More Info


After undergoing knee surgery, such as arthroscopy for femoral distal correction and partial meniscectomy, experiencing swelling is a common occurrence. Swelling, or edema, is a natural response of the body to surgical trauma. It is part of the healing process, as the body sends fluids and inflammatory cells to the area to promote recovery. However, the degree of swelling can vary based on several factors, including the extent of the surgery, individual healing responses, and adherence to post-operative care protocols.

In your case, one month post-surgery, it is not unusual to still observe significant swelling in the knee. This can be exacerbated by activities such as bending and lifting the leg, even if you are engaging in rehabilitation exercises. Ice therapy, which you are already utilizing, is beneficial in managing swelling and should be continued as needed. Elevating the leg and minimizing activities that put stress on the knee can also help reduce swelling.

As for when you can walk independently, this largely depends on your specific recovery progress and the recommendations of your orthopedic surgeon or physical therapist. Generally, patients may begin to walk without assistance anywhere from 4 to 8 weeks post-surgery, assuming there are no complications and that the knee is healing well. It is crucial to follow your healthcare provider's advice regarding weight-bearing activities. They may recommend using crutches or a walker initially to ensure stability and prevent undue stress on the healing tissues.

During your recovery, you should also be aware of signs that may indicate complications, such as increased pain, persistent swelling, or changes in the color or temperature of the knee. If you experience any of these symptoms, it is essential to consult your physician promptly.

In summary, swelling after knee surgery is a normal part of the healing process, and while it can be frustrating, it typically resolves over time. Continue with your rehabilitation exercises, ice therapy, and follow your healthcare provider's guidance regarding walking and weight-bearing activities. With patience and proper care, you should gradually regain strength and mobility in your knee.
