Parosteal Osteosarcoma Surgery and Recovery - Orthopedics

Osteoma surgery


I previously consulted Dr.
Lee regarding the surgery for a bone tumor on my knee.
There is a lump below my left knee that has been present for nearly three years.
I have undergone surgery to take a piece of bone from my right leg and implant it into my left leg.
The pathology report was not available last time, but it has now been diagnosed as: 1.
Parosteal osteosarcoma.
2.
Will it recur? What is the likelihood? 3.
It has been over three months since the surgery, and I can walk normally, but I still cannot squat, run, or jump.
The area around the surgical scar still experiences pain and numbness; is this normal? How long will it take to fully recover? After recovery, will I be able to engage in vigorous exercise? Are there any potential long-term effects?

Hello: In response to your question regarding parosteal osteosarcoma:
1.
The likelihood of recurrence varies based on the histological grade and surgical approach.
The recurrence rate for grade I is 100%; for grade II, it is greater than 80%.
For grades III and IV, if appropriate chemotherapy is administered, the recurrence rates are comparable to those of traditional osteosarcoma.
2.
The primary goal of orthopedic tumor surgery is to save lives, with complete tumor resection being the foremost objective to prevent recurrence and metastasis.
Additionally, preserving the function of the affected limb is important.
The fact that you can walk normally three months post-surgery is a very positive outcome.
For issues such as squatting, running, jumping, and any numbness or pain around the scar, you should consult your attending physician.
Given the excellent results of your surgery, it is important to trust and communicate openly with your physician, as this will be beneficial for you.
Wishing you a speedy recovery.

More Info


Parosteal osteosarcoma is a type of bone tumor that typically arises on the surface of the bone, often affecting the long bones of the body, such as the femur near the knee. Your recent surgery, which involved the removal of the tumor and the grafting of bone from your other leg, is a common approach to treating this condition. Understanding the recovery process and potential complications is crucial for your rehabilitation.

1. Recurrence Rate: The likelihood of recurrence for parosteal osteosarcoma can vary significantly based on several factors, including the tumor's grade and the completeness of the surgical resection. Generally, low-grade tumors (Grade I) have a recurrence rate of about 10-20%, while higher-grade tumors (Grade II and above) can have recurrence rates exceeding 50%. Since your tumor has been diagnosed as parosteal osteosarcoma, it is essential to follow up with your oncologist for regular imaging and assessments to monitor for any signs of recurrence.

2. Post-Surgical Recovery: After three months post-surgery, being able to walk normally is a positive sign of recovery. However, limitations in activities such as squatting, running, and jumping are common in the early stages of rehabilitation. Pain and numbness around the surgical site can also occur as part of the healing process. This discomfort is often due to nerve irritation or inflammation in the surrounding tissues. It is essential to communicate these symptoms to your healthcare provider, as they can provide tailored advice and possibly recommend physical therapy to aid in your recovery.

3. Duration of Recovery: The timeline for complete recovery can vary widely among individuals. Generally, it may take anywhere from six months to a year for full recovery, depending on factors such as your overall health, the extent of the surgery, and adherence to rehabilitation protocols. Engaging in physical therapy can significantly enhance your recovery, helping to regain strength and mobility in your leg.

4. Return to Physical Activity: Once you have fully healed and received clearance from your healthcare provider, you may gradually return to physical activities. However, it is crucial to approach this cautiously. High-impact activities like running and jumping may need to be avoided initially, as they can place excessive stress on the healing bone and surrounding tissues. Your healthcare provider or physical therapist can guide you on when and how to safely resume these activities.

5. Potential Long-term Effects: While many patients recover well from parosteal osteosarcoma surgery, some may experience long-term effects, such as chronic pain or stiffness in the affected area. Regular follow-ups with your healthcare team can help manage these symptoms effectively. Additionally, maintaining a healthy lifestyle, including proper nutrition and exercise, can support your overall recovery and well-being.

In conclusion, while the journey of recovery from parosteal osteosarcoma surgery can be challenging, understanding the potential for recurrence, the recovery timeline, and the importance of rehabilitation can empower you to take an active role in your healing process. Always keep an open line of communication with your healthcare team to address any concerns and to optimize your recovery strategy.
