Chondroblastoma Treatment Pune
At Sancheti Hospital, our Ortho Onco experts manage Chondroblastoma with precise surgery and post-op rehab to preserve joint movement and function.
Overview
Chondroblastoma is a rare, non-cancerous bone tumor that develops from immature cartilage cells called chondroblasts. While these cells normally help maintain healthy cartilage structure, in chondroblastoma, they remain immature and continue dividing uncontrollably, which can damage nearby bone, joints, and growth plates.
This benign bone tumor is extremely uncommon, making up less than 1% of all primary bone tumors. The condition primarily occurs in children and young adults, with most cases diagnosed between ages 11 and 25. Males are affected twice as often as females.
Chondroblastoma typically develops at the ends of long bones, such as the thigh bone (femur), upper arm bone (humerus), and shin bone (tibia). The knee area is particularly common. While classified as benign, in very rare cases (less than 1%), these tumors can spread to the lungs.
Symptoms
The symptoms of chondroblastoma usually develop slowly over months or even years before diagnosis. Understanding these signs is crucial for early detection and treatment.
The most common symptoms include:
- Pain: The primary complaint, ranging from mild aching to severe sharp sensations. This pain often gets worse over time and may initially be mistaken for a sports injury or minor strain.
- Swelling: Localized swelling, redness, and warmth around the affected area due to inflammation. However, there may not always be a visible lump since tumors develop deep within the bone.
- Joint stiffness: Patients experience reduced range of motion in nearby joints, often with fluid buildup.
- Limping: When the tumor affects weight-bearing bones like those in the leg, walking becomes difficult and limping is common.
- Muscle weakness: The muscles near the affected bone may become weak or appear smaller due to decreased use.
In rare cases, if the tumor damages a growth plate in children, differences in limb length may occur. For tumors in unusual locations like the skull, patients might experience seizures, ringing in the ears, dizziness, or hearing problems.
Causes
The exact cause of Chondroblastoma remains unknown. Scientists believe these tumors develop from immature cartilage cells located in the growth plates at the ends of bones near joints.
Current research suggests that changes in growth signaling molecules might play a role, possibly related to hormonal changes before growth plate closure. Recent studies have identified specific genetic mutations in the H3F3B gene that are commonly found in chondroblastoma cases.
Interestingly, 20-25% of chondroblastoma cases occur alongside aneurysmal bone cysts, though this association doesn’t explain the root cause of the tumor itself.
Risk Factors
While chondroblastoma is rare, certain factors increase the likelihood of developing this condition:
- Age: Most cases occur in people under 30, with the highest risk between ages 11-25
- Gender: Males are affected twice as often as females
- Bone location: Over 75% of cases occur in long bones, particularly near joints
- Growth plate status: Higher risk in individuals with open growth plates
Diagnosis
Diagnosis of chondroblastoma requires a comprehensive approach combining clinical examination, imaging studies, and tissue analysis.
The diagnostic process typically includes:
Physical Examination: Doctors check for tenderness, swelling, joint stiffness, and reduced range of motion in the affected area.
Imaging Studies:
- X-rays: Usually the first test, showing areas of bone loss with possible dense borders around the tumor
- MRI: Provides detailed images to distinguish chondroblastoma from other conditions and assess the tumor’s extent
- CT scan: Offers detailed cross-sectional images, excellent for detecting subtle calcifications within the tumor
Biopsy: A definitive diagnosis of chondroblastoma requires examining tissue samples under a microscope. This confirms the presence of characteristic features unique to chondroblastoma.
Types
Chondroblastoma doesn’t have distinct types, but its presentation varies based on location and patient age:
Classic Location: Most common in the epiphysis of long bones in children and young adults, particularly affecting the upper arm, thigh, and shin bones.
Atypical Locations: Less commonly occurs in flat bones (pelvis, shoulder blade), skull bones, or smaller bones of hands and feet. These cases can be more challenging to diagnose.
With Aneurysmal Bone Cyst: 20-25% of cases include a secondary aneurysmal bone cyst component, which can complicate diagnosis if not properly sampled during biopsy.
Stages
Chondroblastoma is staged using the Enneking classification system, which helps guide treatment decisions:
- Stage 1 (Latent): Inactive tumors that are often discovered accidentally, well-contained within the bone
- Stage 2 (Active): Most chondroblastoma cases fall here – symptomatic tumors showing active but contained growth
- Stage 3 (Aggressive): Tumors that break through bone and extend into surrounding soft tissues, requiring more extensive treatment
Treatment
The primary treatment for chondroblastoma is surgical removal, as these tumors don’t resolve on their own. The goal is complete tumor removal while preserving healthy bone and joint function.
Main Treatment Options:
Surgical Curettage: The most common approach, involving careful scraping of the tumor from the bone using specialized instruments. Complete removal is essential to prevent recurrence.
Extended Curettage: Involves removing additional tissue layers around the tumor cavity to further reduce recurrence risk.
Bone Grafting: After tumor removal, the bone defect is filled with healthy bone tissue from the patient’s own body or a donor, or with bone cement.
Adjunctive Therapies: Additional treatments during surgery to destroy remaining tumor cells:
- Chemical treatments using agents like phenol
- Cryosurgery using extreme cold (liquid nitrogen)
- Heat cauterization to burn remaining cells
Radiofrequency Ablation: A minimally invasive option for smaller tumors (1.5-2.5 cm), using high-frequency electrical currents to generate heat and destroy tumor cells.
Chemotherapy and radiotherapy have limited roles in chondroblastoma treatment due to its benign nature.
Rehabilitation
Recovery after treatment for chondroblastoma focuses on restoring joint function, rebuilding muscle strength, and returning to normal activities.
Recovery Timeline:
- Immediate recovery: Significant pain reduction shortly after surgery, with possible overnight hospital stay
- Early mobilization: Non-weight-bearing exercises begin within one week
- Gradual progression: Light weight-bearing exercises start around six weeks post-surgery
- Full recovery: Most patients return to normal activities within six months
Physical therapy is essential for optimal recovery, focusing on gradually increasing activity levels while protecting the healing bone and joint.
Complications
While chondroblastoma is benign, several complications can occur:
- Recurrence: The most common complication, with rates ranging from 5-40%. Usually occurs within the first two years after treatment.
- Growth plate damage: In children and young adults, aggressive surgery may cause premature growth plate closure, leading to limb length differences.
- Joint damage: Surgery near joints can damage cartilage, potentially causing early arthritis.
- Surgical complications: Include infection, bleeding, nerve damage, and bone fractures.
Metastasis: Extremely rare (less than 1%), but chondroblastoma can occasionally spread to the lungs. These cases are usually non-progressive and manageable.
Prevention
Since the exact cause of chondroblastoma is unknown, there are no established prevention methods. The focus remains on early recognition of symptoms and prompt medical evaluation.
Key prevention strategies include:
- Awareness of symptoms like persistent pain or swelling near joints
- Prompt medical attention for unexplained bone or joint pain in children and young adults
- Regular check-ups for those with risk factors
Living With Chondroblastoma
Living with chondroblastoma primarily involves successful treatment and careful follow-up care to monitor for recurrence or complications.
Long-term Management:
- Regular follow-up appointments every 3-4 months for the first two years, then annually
- Routine X-rays and imaging to monitor for recurrence
- Physical therapy to maintain joint function and muscle strength
- Activity modification as recommended by healthcare providers
Quality of Life: With successful treatment, most patients return to normal activities, including sports and physical activities. The prognosis is generally excellent for those who receive appropriate care.
Multidisciplinary Care: Management involves a team of specialists including orthopedic oncologists, radiologists, pathologists, and rehabilitation specialists working together to provide comprehensive care.

Frequently Asked Questions
Will my child be able to play sports after chondroblastoma treatment?
Yes, most children return to full sports activities within 6 months after successful treatment. However, contact sports may need to be avoided temporarily during initial recovery, and your doctor will provide specific activity guidelines based on the tumor location.
Are there any dietary restrictions after chondroblastoma surgery?
No specific dietary restrictions are needed. However, eating calcium-rich foods (dairy, leafy greens) and protein can help bone healing. Avoid smoking and limit alcohol as these can slow recovery.
Can chondroblastoma be detected in routine health checkups?
Regular checkups rarely detect chondroblastoma since it requires specific imaging. However, don’t ignore persistent bone pain in teenagers – this warrants immediate medical attention even if recent X-rays were normal.
What happens if we choose to wait and watch instead of surgery?
Chondroblastoma doesn’t resolve on its own and will likely continue growing, causing more pain and potential joint damage. Delaying treatment may lead to more complex surgery and longer recovery time, especially if growth plates are affected.
