Patellar Fracture: Do I Need Surgery or Just a Cast? - Orthopedics

Patellar fracture


Hello, doctor.
I fell on January 6 and fractured my patella into two pieces.
The doctor mentioned surgery to insert screws and wires for fixation, but also suggested the option of using a cast for a month.
I would like to opt for surgery and return for a follow-up.
My swelling has decreased somewhat.
Do I still need to undergo surgery?

Dr. Chen Bochen reply Orthopedics


Whether surgery is needed should primarily be determined by X-rays! Just reducing swelling does not mean surgery is unnecessary.
If there is a displaced patellar fracture, it is advisable to proceed with surgical repair; otherwise, it may lead to knee weakness and premature degeneration in the future.
Wishing you a speedy recovery!

When it comes to patellar fractures, the decision to undergo surgery or to simply use a cast largely depends on the specifics of the fracture, including its type, displacement, and the overall condition of the knee joint. In your case, since you mentioned that your patellar fracture involves two fragments, it is essential to evaluate the degree of displacement and the stability of the fracture.

1. Surgical vs. Non-Surgical Treatment: Generally, if the fracture is non-displaced or minimally displaced, conservative treatment with a cast may be sufficient. This approach allows the bone to heal naturally while maintaining the knee's function. However, if the fracture is significantly displaced, surgery is often recommended to realign the fragments and stabilize them using screws or wires. This is crucial for restoring the knee's function and preventing long-term complications such as malunion or nonunion.

2. Recovery and Rehabilitation: If you opt for surgery, the recovery period typically involves immobilization for a few weeks, followed by a structured rehabilitation program. This program usually starts with gentle range-of-motion exercises and progresses to strengthening exercises as healing occurs. If you choose the non-surgical route, you will still need to engage in rehabilitation once the cast is removed to regain strength and mobility.

3. Timing for Surgery: The timing of surgery can also be a critical factor. If the fracture is stable and there is no significant swelling or pain, waiting a little longer may be beneficial. However, if there is any concern about the alignment or stability of the fracture, it is advisable to proceed with surgery sooner rather than later. Delaying surgery in cases of unstable fractures can lead to complications that may require more extensive treatment later.

4. Consultation with Your Surgeon: It is essential to have an open discussion with your orthopedic surgeon regarding your options. They can provide insights based on the specifics of your fracture, your activity level, and your overall health. If you have concerns about surgery, express them to your doctor; they can help clarify the risks and benefits of each approach.

5. Potential Risks of Non-Surgical Treatment: While many patients do well with conservative treatment, there are risks associated with not having surgery, especially if the fracture is unstable. These risks include improper healing, persistent pain, and decreased function of the knee joint. In some cases, if the fracture does not heal correctly, a second surgery may be necessary.

6. Post-Operative Considerations: If you decide to go ahead with surgery, be prepared for a recovery process that may involve physical therapy. The goal of rehabilitation is to restore knee function, strength, and range of motion. Adhering to your rehabilitation program is crucial for a successful outcome.

In summary, the decision to proceed with surgery for your patellar fracture should be based on the fracture's characteristics, your symptoms, and your surgeon's recommendations. If the fracture is stable and you are not experiencing significant pain or swelling, conservative treatment may be a viable option. However, if there is any doubt about the fracture's stability, surgery may be the best course of action to ensure proper healing and function of your knee. Always consult with your orthopedic specialist to make the most informed decision regarding your treatment plan.
