Patellar fracture


Hello Doctor: I suffered a patellar fracture at the end of August (it was a transverse fracture, splitting into two parts) and I am currently in the fourth week post-surgery.
I am undergoing rehabilitation and have achieved 90 degrees of knee flexion.
My physical therapist mentioned that I need to strengthen my quadriceps, as I feel some muscle atrophy.
I would like to ask you:
1.
When I perform short arc straight leg raises (knee extension), I experience significant pain above the patella in a deep area, making it difficult to lift my leg.
Could this pain be related to the presence of the steel pins? After performing patella mobilization, the pain improves slightly, but it still persists.
2.
Will the steel pins and wires inside my knee need to be removed later? Is this typically done one year after surgery? I feel tightness and tension when bending my knee to 90 degrees.
3.
During the time that I have the steel pins, will I be able to achieve full range of motion in my knee flexion?

Dr. Li Yongheng reply Orthopedics


Hello, it has been 4 weeks since your patellar fracture surgery, and currently, your knee flexion has reached 90 degrees.
Due to the protrusion of the screws, it may cause pain.
It is recommended to remove the screws and wires one year after the fracture.
You should be able to achieve full range of motion in your knee flexion within 3 months post-surgery.
Wishing you a speedy recovery.

Understanding patellar fractures, particularly in the context of recovery, pain management, and rehabilitation, is crucial for achieving optimal outcomes. Given your situation, where you experienced a transverse patellar fracture and are currently four weeks post-surgery, it’s important to address your concerns systematically.

1. Pain During Rehabilitation: The pain you are experiencing during short arc straight leg raises (SLR) is not uncommon, especially after a patellar fracture. The discomfort you feel above the patella could be attributed to several factors. First, the presence of hardware, such as screws or plates, can sometimes cause localized pain, particularly if they are pressing against surrounding tissues or if there is inflammation in the area. Additionally, muscle atrophy and weakness in the quadriceps can lead to compensatory movements that may exacerbate pain. It’s also possible that the pain is related to the healing process of the bone and surrounding soft tissues. If the pain persists or worsens, it would be advisable to consult your orthopedic surgeon to evaluate the hardware and ensure that there are no complications.

2. Removal of Hardware: Typically, the decision to remove internal fixation devices like screws or wires depends on various factors, including the type of fracture, the healing process, and any ongoing symptoms. In many cases, if the hardware is not causing significant pain or complications, it may be left in place indefinitely. However, if you are experiencing persistent discomfort, your surgeon may recommend removal, often around one year post-surgery, but this can vary based on individual circumstances. It’s essential to have a follow-up appointment with your orthopedic surgeon to discuss your specific case and the need for hardware removal.

3. Achieving Full Range of Motion: The goal of rehabilitation after a patellar fracture is to regain full range of motion and strength. While you are currently able to flex your knee to 90 degrees, achieving full range of motion (typically 0-135 degrees or more) is a common goal in rehabilitation. The presence of hardware can sometimes limit motion initially, but with appropriate rehabilitation, many patients can achieve full range over time. It’s crucial to follow your physical therapist’s guidance and engage in exercises that promote flexibility and strength in the quadriceps and surrounding muscles.
In addition to these points, here are some general recommendations for your recovery:
- Pain Management: Continue to manage pain with prescribed medications, and consider using ice therapy to reduce inflammation. If NSAIDs are contraindicated for you, discuss alternative pain management strategies with your healthcare provider.

- Physical Therapy: Engage in a structured physical therapy program that focuses on both passive and active range of motion exercises, strengthening the quadriceps, and improving overall knee function. Your therapist can provide tailored exercises that accommodate your pain levels.

- Monitoring Progress: Keep track of your pain levels, range of motion, and any changes in your symptoms. Regular follow-ups with your orthopedic surgeon and physical therapist will help ensure that you are on the right track.

- Patience and Consistency: Recovery from a patellar fracture can be a gradual process. Consistency in your rehabilitation exercises and patience with your body’s healing process are key to achieving the best possible outcome.

In summary, while the journey to recovery from a patellar fracture can be challenging, with proper management, rehabilitation, and communication with your healthcare team, you can work towards regaining full function and minimizing pain. Always feel free to reach out to your medical team with any concerns or questions as you progress through your recovery.
