Patella Fracture
Have you fallen on your knee and are experiencing intense pain with inability to bend your leg? Patella fracture is a common knee injury that requires rapid orthopedic or surgical management. In Tunisia, experienced orthopedists ensure the treatment of patella fractures with modern techniques (screws, pins, cerclage) at competitive prices.
Patella Fracture: What is it?
Patella fracture (or kneecap) is a break of the bone located at the front of the knee. The patella is a small triangular bone that protects the knee joint and allows transmission of quadriceps force for leg extension.
Patella fractures often occur following a fall on the knee, a direct impact (car accident) or a violent contraction of the quadriceps. They can be simple (non-displaced) or complex (displaced, comminuted).
Types of Patella Fractures
Patella fractures are classified according to their location and complexity. Transverse fracture is the most common. Comminuted fracture has multiple fragments. Vertical fracture is less common. Osteochondral fracture affects the articular cartilage. Finally, a fracture may be associated with patellar tendon injury. These fracture types guide treatment choice.
Causes of Patella Fracture
Patella fractures have several causes. A fall on the knee is the most common cause. A direct impact during a car accident is also a cause. A violent contraction of the quadriceps can cause a fracture. A sports accident is another possible cause. Osteoporosis weakens bones and promotes fractures. These mechanisms must be considered for diagnosis.
Symptoms of Patella Fracture
A patella fracture manifests with characteristic symptoms. Intense pain is localized to the front of the knee. Significant swelling appears quickly. Bruising is visible. Inability to bend the knee is common. Inability to stand up is also possible. Deformity is visible in case of displaced fracture. These signs should alert and lead to consultation.
Diagnosis of Patella Fracture
Diagnosis of a patella fracture is based on several examinations. Clinical examination includes inspection and palpation. X-rays from front and side of the knee are performed. CT scan is used for comminuted fractures. These examinations allow specification of the fracture type and guide treatment.
Treatment of Patella Fracture
Treatment depends on the type of fracture, its displacement and the integrity of the patellar tendon.
1. Orthopedic Treatment (non-surgical)
Conservative treatment is indicated for non-displaced fractures with a gap less than 3 mm. Immobilization with a cast or resin splint in extension is maintained for 4 to 6 weeks. Weight-bearing is prohibited during this period. Radiological monitoring is provided with checks at 15 days and 1 month. This approach is suitable for simple fractures.
2. Surgical Treatment (osteosynthesis)
Patella surgery is indicated for displaced, comminuted fractures or with tendon injury. Screw osteosynthesis is used for simple transverse fractures. Tension band wiring is the reference technique. Plate and screw osteosynthesis is reserved for comminuted fractures. Patellar tendon repair is performed if necessary. The procedure is under general or spinal anesthesia. It lasts 45 to 90 minutes. Hospitalization is 2 to 4 days.
Specific Surgical Techniques
Surgical options for patella fractures are varied. Tension band wiring uses two pins connected by a figure-eight wire. Compression screws are used for transverse fractures. Locking plate is reserved for complex comminuted fractures. These techniques allow optimal stabilization of fragments.
Post-Operative Course and Recovery
Recovery after a patella fracture is well codified. Immobilization with a splint or cast in extension is maintained for 4 to 6 weeks. Moderate pain is controlled with painkillers. Rehabilitation by physiotherapy begins after 4 to 6 weeks. Mobilization is progressive for knee flexion. Full recovery occurs in 3 to 6 months.
Rehabilitation Exercises
Rehabilitation after a patella fracture is essential. It includes knee mobilization in progressive flexion-extension. Muscle strengthening of the quadriceps and hamstrings is performed. Balance work is important for standing. Walking is progressively resumed with aids. These exercises allow recovery of knee function.
Risks and Complications
Several complications may occur after a patella fracture. Infection is rare and prevented by antibiotic prophylaxis. Minimal bleeding resolves spontaneously. Joint stiffness is prevented by early rehabilitation. Risk of post-traumatic arthritis exists in the long term. Non-union is a rare healing defect. Patellar tendon injury is a possible complication.
Prices for Patella Fracture Treatment in Tunisia
Tunisia offers very competitive prices for patella fracture treatment. An orthopedic consultation costs between €80 and €120. A cast or resin splint costs from €150 to €300. Screw osteosynthesis is offered from €1,500 to €2,500. Tension band wiring is available from €2,000 to €3,500. Plate osteosynthesis costs from €3,000 to €4,500. A rehabilitation package of 15 physiotherapy sessions is offered from €300 to €600.
Frequently Asked Questions about Patella Fracture
1How long is the hospital stay for a patella fracture in Tunisia?
Hospitalization is generally 2 to 4 days for a fracture requiring osteosynthesis. For simple fractures treated with a cast, a 24-hour hospital stay may be sufficient. Duration depends on the complexity of the fracture.
2When can you bend the knee after a patella fracture?
Immobilization lasts 4 to 6 weeks depending on the type of fracture. After cast removal, rehabilitation is started to progressively restore knee flexion. Full flexion is generally achieved in 2 to 3 months.
3What are the risks of patella fracture surgery?
Risks are low and include: infection, bleeding, joint stiffness, post-traumatic arthritis, non-union, and patellar tendon injury.
4Can a patella fracture cause knee arthritis?
Yes, post-traumatic arthritis is a common long-term complication of patella fractures, particularly if the articular surface is irregular. Precise anatomical reduction reduces this risk.
5When can you return to sports after a patella fracture?
Return to sports is progressive: low-impact sports (swimming, cycling) after 3-4 months, impact sports (football, basketball, running) after 4-6 months. Complete rehabilitation is essential.
6What is the difference between a simple and a complex patella fracture?
A simple fracture is a non-displaced fracture or with a gap less than 3 mm, treated by immobilization. A complex fracture is a displaced, comminuted fracture or with patellar tendon injury, requiring osteosynthesis with screws, pins or cerclage.
7Should osteosynthesis hardware (screws, pins, cerclage) be removed?
Removal of osteosynthesis hardware is optional and depends on symptoms. It is generally performed 12 to 18 months after surgery if the hardware is uncomfortable (pain, skin irritation). Removal is a short surgical procedure under local or general anesthesia.
