Rehabilitation after knee surgery
1.
After knee surgery, it is common to experience poor blood circulation in the lower extremities and hematoma around the knee for several weeks to months.
Therefore, while the wound has not yet healed, passive range of motion exercises for the knee can be performed.
As the swelling gradually subsides, active muscle contraction exercises for the lower extremities (including the quadriceps and gastrocnemius muscles) can be initiated.
To reduce lower extremity edema, it is advisable to elevate the legs above heart level periodically to promote venous return.
2.
Redness and swelling around the wound may indicate immature scar tissue, a foreign body reaction to the sutures, or a wound infection.
A proper assessment of the actual condition is necessary for accurate diagnosis.
3.
Cosmetic tape is generally applied perpendicular to the wound, and it should be changed every two to three days.

Post-surgery knee rehabilitation is crucial for a successful recovery and to regain full function of the knee joint. Here are some essential tips and guidelines for recovery and care after knee surgery:

1. Initial Care and Rest
After knee surgery, it is vital to allow the knee to rest and heal. For the first few days, you should keep your leg elevated to reduce swelling. Use ice packs on the knee for 15-20 minutes every couple of hours to help manage swelling and pain. Make sure to follow your surgeon's instructions regarding weight-bearing activities.

2. Managing Swelling
Swelling is a common occurrence after knee surgery. To manage it, keep your leg elevated above the level of your heart when resting. Compression bandages can also help reduce swelling. If you notice excessive swelling, redness, or warmth around the incision site, it is essential to contact your healthcare provider, as these could be signs of infection.

3. Rehabilitation Exercises
Rehabilitation exercises typically begin within a few days after surgery, depending on your doctor's recommendations. Here are some common exercises:
- Ankle Pumps: While lying down, flex and point your toes to promote circulation.

- Quadriceps Sets: Tighten the muscles on the top of your thigh, hold for a few seconds, and then relax.

- Straight Leg Raises: While lying down, keep one leg bent and lift the other leg straight up to strengthen the quadriceps.

- Heel Slides: While sitting or lying down, slide your heel towards your buttocks to bend your knee gently.

- Knee Flexion and Extension: Gradually work on bending and straightening your knee to improve range of motion.

4. Progressive Weight Bearing
As you recover, your doctor will guide you on when to start putting weight on your knee. Initially, you may need crutches or a walker. Gradually increase your weight-bearing activities as tolerated, but avoid putting too much pressure on the knee too soon.

5. Pain Management
It is normal to experience some pain and discomfort after surgery. Over-the-counter pain medications or those prescribed by your doctor can help manage this. If you experience severe pain that does not improve with medication, consult your healthcare provider.

6. Monitoring the Incision Site
Redness and swelling around the incision site can be normal, especially in the first few weeks. However, if the redness spreads, or if you notice pus or an increase in pain, it may indicate an infection. Keep the incision clean and dry, and follow your surgeon's instructions regarding dressing changes.

7. Use of Topical Treatments
If you are using silicone gel sheets or other topical treatments for scar management, apply them as directed. Typically, these should be applied to clean, dry skin and can be worn for several hours a day. Follow the specific instructions provided by your healthcare provider regarding when and how to use these products.

8. Follow-Up Appointments
Regular follow-up appointments with your orthopedic surgeon or physical therapist are essential to monitor your recovery progress. They can adjust your rehabilitation plan as needed and provide additional guidance based on your healing process.

9. Patience and Consistency
Recovery from knee surgery can take time, and it is essential to be patient with yourself. Consistency in performing your rehabilitation exercises and following your healthcare provider's advice will lead to better outcomes.

Conclusion
In summary, post-surgery knee rehabilitation involves a combination of rest, elevation, gradual weight-bearing, and specific exercises to restore function. Monitoring the incision site for signs of infection and managing swelling are also critical components of recovery. Always consult your healthcare provider for personalized advice and adjustments to your rehabilitation plan. With dedication and proper care, you can achieve a successful recovery and return to your daily activities.
