Patellar comminuted fracture
I have a large open wound on my knee due to a car accident, and I have a comminuted fracture of the patella with one-third removed and two-thirds preserved without the use of steel pins.
How long will it take for the bone to heal? How long will rehabilitation take? Will there be any long-term effects? What else should I be aware of?

The approximate healing time is three months, with rehabilitation lasting three to six months.
There is a possibility of degenerative joint changes between the patella and femur in the future.
Before complete healing, the knee joint should not be flexed excessively.

Recovering from a patellar fracture, especially one that involves significant damage and the removal of a portion of the patella, is a complex process that requires careful management and rehabilitation. Given the details of your injury, including the open wound and the fact that one-third of the patella was removed, it is essential to understand the recovery timeline, rehabilitation considerations, potential complications, and precautions you should take.
Recovery Timeline
1. Initial Healing Phase (0-6 weeks): After surgery, the initial focus will be on healing the surgical site and managing pain. During this period, you will likely be advised to keep weight off the affected leg and may be given a brace to stabilize the knee. The bone healing process typically begins within the first few weeks, but complete healing of the bone can take longer, especially with a significant injury like yours. Generally, bone healing can take anywhere from 6 to 12 weeks, depending on the severity of the fracture and individual healing rates.
2. Rehabilitation Phase (6-12 weeks): Once the initial healing has occurred, physical therapy will become crucial. Rehabilitation usually starts with gentle range-of-motion exercises to prevent stiffness and improve flexibility. As healing progresses, strength training and functional exercises will be introduced. The timeline for returning to normal activities can vary, but many patients can expect to engage in more active rehabilitation around the 6 to 12-week mark.
3. Long-Term Recovery (3-6 months): Full recovery, including the return to sports or heavy physical activities, may take several months. It is not uncommon for patients to experience lingering pain or discomfort for up to 6 months or longer, particularly if there was significant damage to the surrounding soft tissues or if the knee joint was affected.
Rehabilitation Considerations
- Physical Therapy: Engaging in a structured physical therapy program is essential. Your therapist will guide you through exercises tailored to your specific needs, focusing on restoring range of motion, strength, and stability in the knee.
- Gradual Weight Bearing: Depending on your surgeon's advice, you may start with partial weight-bearing activities and gradually progress to full weight-bearing as tolerated.
- Pain Management: Managing pain effectively during rehabilitation is crucial. Your healthcare provider may recommend medications or alternative therapies to help with pain control.
Potential Complications and Long-Term Effects
- Post-Traumatic Arthritis: One of the most common long-term complications after a patellar fracture is the development of post-traumatic arthritis. This can occur due to the damage to the cartilage or the joint surfaces during the injury and surgery.
- Knee Instability: Depending on the extent of the injury and the surgical intervention, some patients may experience knee instability, which can affect mobility and function.
- Range of Motion Limitations: Some individuals may have difficulty regaining full range of motion in the knee, which can impact daily activities and quality of life.
Precautions and Recommendations
- Follow-Up Appointments: Regular follow-ups with your orthopedic surgeon are essential to monitor the healing process and make necessary adjustments to your rehabilitation plan.
- Avoid High-Impact Activities: Until you have fully healed and received clearance from your healthcare provider, avoid high-impact activities that could stress the knee joint.
- Listen to Your Body: Pay attention to any signs of pain or discomfort during rehabilitation. If you experience increased pain, swelling, or instability, consult your healthcare provider.
- Nutrition and Bone Health: Ensure you are consuming a balanced diet rich in calcium and vitamin D to support bone healing. Discuss with your healthcare provider if supplements are necessary.
In summary, the recovery from a patellar fracture with significant damage can be a lengthy process, often requiring several months of rehabilitation. It is crucial to adhere to your healthcare provider's recommendations, engage in physical therapy, and monitor for any complications. With proper care and rehabilitation, many individuals can return to their previous level of activity, although some may experience long-term effects.
