Managing Knee Injuries: Patellar Healing and ACL Reconstruction Options - Orthopedics

More Info

---

Managing knee injuries, especially after significant trauma such as a car accident, can be quite complex. In your case, you have multiple factors to consider: the healing of your patella (kneecap), the presence of metal hardware (the steel pins), and the recent injury to your posterior cruciate ligament (PCL).
First, let’s address the healing of your patella. It’s crucial that the bone has healed sufficiently before any surgical intervention. If your orthopedic surgeon has indicated that the steel pins can be removed, this suggests that the bone has healed to a degree that it can withstand the stresses of daily activities without the support of the hardware. However, the presence of a small crack or fissure in the patella may require careful monitoring.
Regarding your recent PCL injury, the timing of surgery is essential. Generally, if a ligament is torn, surgical reconstruction is often recommended to restore stability to the knee. However, the decision to perform surgery on the PCL or to remove the steel pins from the patella first depends on several factors, including the extent of the ligament injury, the stability of your knee, and the condition of your patella.

In many cases, it is possible to perform both procedures simultaneously, especially if the surgeon believes that doing so will not compromise the healing of either structure. However, this decision ultimately lies with your orthopedic surgeon, who will assess the risks and benefits based on your specific situation. It is important to communicate openly with your surgeon about your concerns and the best course of action.

As for your question about how long you can delay the ligament surgery, it is generally advisable to proceed with ligament reconstruction sooner rather than later, particularly if you are experiencing instability or pain. Delaying surgery can lead to further complications, including additional damage to the knee joint or surrounding structures.

In terms of sleeping positions, it is often recommended to keep the knee in a neutral position, avoiding excessive bending or twisting. You may find it helpful to use a pillow under your knee for support, which can help alleviate discomfort and promote better alignment. If you experience swelling, elevating your leg can also be beneficial.

Before surgery, gentle rehabilitation exercises can help maintain range of motion and prevent stiffness. Here are a few simple exercises you can do at home:
1. Quadriceps Sets: Sit with your leg straight and tighten the muscle on the top of your thigh. Hold for 5 seconds and release. Repeat 10-15 times.

2. Straight Leg Raises: While lying down, keep one leg bent and the other straight. Slowly raise the straight leg to the height of the bent knee, hold for a few seconds, and lower it back down. Repeat 10-15 times.

3. Heel Slides: While sitting or lying down, slowly slide your heel towards your buttocks, bending your knee as much as comfortable. Then slide it back out. Repeat 10-15 times.

4. Ankle Pumps: While lying down, flex and point your toes to promote circulation in your leg. This can be done frequently throughout the day.

Always consult with your healthcare provider before starting any new exercise regimen, especially after a significant injury. They can provide personalized recommendations based on your current condition and recovery goals.

In summary, the management of your knee injuries requires a careful assessment of both the healing of your patella and the state of your PCL. Open communication with your orthopedic surgeon will be key in determining the best surgical approach and timing. In the meantime, gentle rehabilitation exercises and proper sleeping positions can help maintain your knee's function and comfort.
