Rehabilitation after screw removal surgery for patellar fracture?


Hello, doctor! I have a patellar fracture in my knee due to a car accident, which broke into three large pieces and several smaller fragments.
I had a health insurance-covered surgery with bone screws, but the first time I didn't use bone graft material.
After six months, when the screws were removed, I may have started walking too early, and an X-ray revealed that there was still a fracture.
Therefore, I consulted another doctor who performed another surgery, this time using artificial bone graft material.
It has been a little over a year since the surgery, and I am scheduled to have the screws removed ten days post-operation.
I would like to ask: (1) After the screw removal, how many days will it take before I can bend my knee to 90 degrees? How many days after that can I practice the maximum angle of my calf and thigh touching? (2) Three days post-surgery, I have been using crutches and a walker.
Can I put weight on the affected limb while walking with assistive devices? How many days after surgery would you recommend before I can walk without assistive devices? Thank you! (3) After the screw removal surgery, how many days will it take before I can ride a motorcycle and drive? How many days after that can I practice squatting? How many days after that can I perform jumping and kneeling movements?

Hello, regarding the general conditions after a patellar fracture, the decision about your personal situation should be made by your surgeon based on the surgical status, X-rays, and physical examination.

(1) After the removal of the screws, when can I bend my knee to 90 degrees? When can I practice the maximum angle of the calf and thigh touching? >>> After screw removal, you can bend to 60 degrees, and after suture removal, you can bend to 90 degrees.
If the fracture has healed well, you can achieve maximum flexion after one month.
(2) Three days post-surgery, I have been using crutches and a walker.
Can I bend and put weight on the affected limb while using these aids? When is it recommended to walk without aids? Thank you! >>> Generally, after screw removal, you do not need to rely on crutches.
(3) After screw removal surgery, when can I ride a motorcycle and drive? When can I practice squatting directly? When can I perform jumping and kneeling movements? >>> You can squat one week after suture removal, and you can jump and kneel after one month.
The above information reflects general conditions, but it is best to consult your attending physician for your specific situation.

Rehabilitation after a patellar fracture and subsequent screw removal is a critical phase in the recovery process. Given the complexity of your injury, which involved multiple fragments and the use of bone grafting, it is essential to approach rehabilitation with care and patience. Here are some key recovery tips and timelines based on your questions:
1. Knee Flexion Post-Screw Removal: After the removal of screws, it is generally advisable to begin gentle range-of-motion exercises as soon as you feel comfortable, typically within a few days post-surgery. However, achieving a 90-degree flexion may take longer, often around 2 to 4 weeks post-surgery, depending on your pain tolerance and the stability of the knee. It is crucial to listen to your body; if you experience significant pain, it may be a sign to ease off and consult your physician or physical therapist.

2. Use of Assistive Devices: Initially, using crutches or a walker is recommended to offload the affected leg and prevent undue stress on the healing structures. While using these devices, you can gently bend your knee, but avoid putting full weight on it until cleared by your healthcare provider. Typically, you may start to transition away from assistive devices within 1 to 2 weeks post-surgery, depending on your progress and comfort level.

3. Resuming Activities: Regarding activities such as riding a motorcycle or driving, it is generally recommended to wait at least 1 to 2 weeks after surgery, provided you have regained sufficient range of motion and strength to operate the vehicle safely. For squatting, you might be able to start practicing within 4 to 6 weeks post-surgery, but again, this depends on your comfort and stability. High-impact activities like running, jumping, or kneeling may take longer—often around 3 to 6 months—before you can safely resume them without risking re-injury.


Additional Rehabilitation Tips:
- Physical Therapy: Engaging in a structured physical therapy program is vital. A physical therapist can provide tailored exercises to improve strength, flexibility, and stability in your knee. They will also monitor your progress and adjust your rehabilitation plan as needed.

- Pain Management: If you experience pain during rehabilitation, consider using ice packs to reduce swelling and discomfort. Over-the-counter pain medications (if not contraindicated) can also help manage pain levels.

- Gradual Progression: Focus on gradual progression in your rehabilitation exercises. Start with gentle range-of-motion exercises, then gradually incorporate strengthening exercises for the quadriceps, hamstrings, and calf muscles as tolerated.

- Listen to Your Body: Pay attention to your body’s signals. If you experience increased pain or swelling, it may be necessary to modify your activities or consult your healthcare provider.

- Avoid High-Impact Activities Initially: Until you have regained sufficient strength and stability, avoid high-impact activities that could stress the knee joint.

- Follow-Up Appointments: Regular follow-up appointments with your orthopedic surgeon or physical therapist are essential to monitor your healing progress and make necessary adjustments to your rehabilitation plan.

In conclusion, recovery from a patellar fracture and screw removal is a gradual process that requires patience and adherence to a structured rehabilitation program. By following these guidelines and working closely with your healthcare team, you can optimize your recovery and return to your desired activities safely.
