Right knee swelling surgery (rehabilitation issues)


Hello, Doctor.
When I was about 13 years old, I had an accident while riding a bicycle, which caused bruising or swelling in my right knee; the bone was not injured (I'm not sure, as I was treated at Linkou Chang Gung Memorial Hospital).
After that, I was able to walk without issues, but if I use my knee for a long time (such as during exercise or hiking), I experience pressure pain.
Therefore, I wanted to have the swelling removed while I am still young, and I underwent surgery on September 13 of this year.
Due to severe swelling after the surgery, I would like to ask if it is normal that I still cannot bend my knee about a month post-operation (currently, I can walk, but there is bruising on the inner side of my right thigh, and my muscles feel tight; I need to use a crutch to go up and down stairs).
If this is normal, how long does recovery typically take? How should I gradually rehabilitate my knee to regain its range of motion? Thank you, Doctor.

Dr. Shi Guozheng reply Orthopedics


Swelling after knee surgery typically lasts for about six weeks.
Rehabilitation involves gradually bending the knee, which can be assisted with heat therapy.
The muscles of the thigh and calf can be stretched while sitting, and then slowly bent back.
This should be done three times a day for about 20 minutes each session.
If the knee becomes very swollen after exercising, cold or ice therapy can be applied to reduce the swelling.
Most individuals will see improvement within three months.

Post-surgery recovery, especially after knee surgery, can be a challenging journey, particularly when dealing with swelling and limited range of motion. Your situation, having undergone surgery for a tumor removal in the knee, is not uncommon. It’s important to understand that the healing process varies significantly from person to person, influenced by factors such as the extent of the surgery, individual health conditions, and adherence to rehabilitation protocols.

Firstly, it’s normal to experience swelling after knee surgery. This is part of the body’s natural healing response. Swelling can be exacerbated by factors such as prolonged sitting or standing, and it can also affect your range of motion. In your case, the inability to bend your knee one month post-surgery is not unusual, especially if the surgery involved significant manipulation of the tissues around the knee joint.
To manage swelling, several strategies can be employed:
1. Elevation: Keeping your knee elevated above the level of your heart can help reduce swelling. This is particularly effective when combined with ice therapy.

2. Ice Therapy: Applying ice packs to the knee for 15-20 minutes several times a day can help reduce inflammation and numb the area, providing pain relief.

3. Compression: Using a compression bandage can help control swelling. However, it’s important not to wrap it too tightly, as this can impede circulation.

4. Gentle Movement: While it may be painful, gentle movement can help promote circulation and reduce stiffness. Consult your physical therapist for appropriate exercises that can be done without exacerbating your pain.

Regarding your rehabilitation process, it’s crucial to follow a structured program designed by your healthcare provider or physical therapist. Here are some general guidelines for gradually increasing your knee flexion:
1. Passive Range of Motion Exercises: Initially, your therapist may guide you through passive range of motion exercises, where they help you bend and straighten your knee without you actively using your muscles.

2. Active Range of Motion Exercises: As you begin to regain some flexibility, you can start doing active range of motion exercises. This includes gentle bending and straightening of the knee while seated or lying down.

3. Strengthening Exercises: Once you have regained some range of motion, strengthening exercises for the quadriceps and hamstrings will be important. These can include straight leg raises, heel slides, and eventually more weight-bearing exercises as tolerated.

4. Functional Activities: Gradually reintroducing functional activities, such as walking, climbing stairs, and eventually more dynamic movements, will be essential for your recovery.

In terms of timeline, many patients can expect to see significant improvements in their range of motion within 6 to 12 weeks post-surgery, but this can vary widely. It’s important to communicate openly with your healthcare team about your progress and any concerns you have. They can adjust your rehabilitation plan as needed based on your recovery.

Lastly, if you continue to experience significant pain or swelling, or if you notice any unusual symptoms such as increased redness, warmth, or fever, it’s crucial to contact your physician. These could be signs of complications that may require further evaluation.

In conclusion, while your recovery may feel slow, patience and adherence to a structured rehabilitation program are key. With time and the right approach, you can expect to regain function and reduce pain in your knee. Always consult with your healthcare provider before making any changes to your rehabilitation plan.
