Swelling After ACL Reconstruction and Meniscus Repair - Orthopedics

More Info

---

Swelling after ACL reconstruction and meniscus repair is a common concern among patients, and it can be attributed to several factors. First, it's essential to understand that the healing process following such surgeries can take time, and swelling is a natural part of that process.
When you undergo ACL reconstruction and meniscus repair, the surgical procedure involves significant manipulation of the knee joint, which can lead to inflammation and swelling. This is your body's response to the trauma of surgery, and it typically peaks within the first few weeks post-operation. However, in some cases, swelling can persist for months, as you've experienced.

There are several reasons why you might still be experiencing swelling in your knee six months after surgery:
1. Inflammation: After surgery, the body initiates an inflammatory response to promote healing. This inflammation can lead to fluid accumulation in the knee joint, causing swelling. While this should gradually decrease, some individuals may experience prolonged inflammation due to various factors, including activity levels and individual healing responses.

2. Scar Tissue Formation: Post-surgical scar tissue can develop around the knee joint, which may contribute to swelling and discomfort. This scar tissue can sometimes restrict movement and lead to a sensation of tightness in the knee.

3. Activity Level: Engaging in physical activities or exercises that put stress on the knee can exacerbate swelling. If you find that walking for extended periods leads to increased swelling, it may be a sign that your knee is still in the recovery phase and requires more time to heal.

4. Meniscus Repair Complications: Although your surgery aimed to repair the meniscus, there is a possibility of re-injury or complications related to the repair itself. If the meniscus has not healed properly or if there is a new tear, this could lead to swelling and discomfort.
5. Joint Effusion: This term refers to the accumulation of excess fluid in the knee joint, which can occur due to inflammation, injury, or irritation. Joint effusion can cause the knee to feel tight and swollen, especially after activity.

6. Underlying Conditions: Sometimes, underlying conditions such as arthritis or other joint issues can contribute to swelling and discomfort in the knee.

Given your symptoms, it is crucial to consult with your orthopedic surgeon or physical therapist. They can perform a thorough evaluation, which may include physical examinations and imaging studies like an MRI, to determine the exact cause of your swelling. They can assess whether the meniscus has re-torn, if there is excess fluid in the joint, or if other complications are present.

In the meantime, here are some general recommendations to manage swelling:
- Rest: Allow your knee to rest, especially after activities that exacerbate swelling.

- Ice Therapy: Applying ice to the knee can help reduce swelling and alleviate pain. Aim for 15-20 minutes of ice application several times a day.

- Elevation: Elevating your knee above heart level can help reduce swelling by promoting fluid drainage.

- Compression: Using a compression bandage or knee sleeve can provide support and help control swelling.

- Gentle Exercises: Engage in gentle range-of-motion exercises as advised by your physical therapist to maintain mobility without overexerting the knee.

In conclusion, while swelling can be a normal part of the recovery process after ACL reconstruction and meniscus repair, persistent swelling warrants further investigation. It is essential to communicate your concerns with your healthcare provider to ensure appropriate management and to rule out any complications. Your recovery journey is unique, and with the right support and rehabilitation, you can work towards regaining full function of your knee.
