1. Distal femur fracture

Distal femur fractures can occur in both younger and elderly patients, with different injury mechanisms. Younger patients typically sustain high-energy trauma, resulting in significant displacement, comminution, and associated injuries. Elderly patients often experience low-energy trauma, such as a slip and fall, leading to spiral-type fractures. Treatment options include non-operative management for nondisplaced fractures or stable elderly patients, and various surgical techniques like plate fixation, retrograde intramedullary nailing, and external fixation, depending on the fracture pattern and patient factors.
2. Patella fracture

Patella fractures can occur through direct or indirect injury mechanisms. Direct injuries, such as falls from a standing height, can cause comminuted fracture patterns, while indirect injuries from forceful quadriceps contraction can lead to transverse fractures. Treatment goals include restoring the extensor mechanism and preserving the patellofemoral relationship. Non-operative management may be appropriate for nondisplaced fractures, while operative treatment with techniques like tension band wiring or partial/total patellectomy is indicated for displaced or unstable fractures.
3. Knee dislocation

Knee dislocations are high-energy injuries that can occur in both low-energy and high-energy trauma settings. They are associated with a high risk of neurovascular injuries, which should be the primary focus of initial evaluation and management. Prompt reduction of the dislocation, followed by assessment and treatment of associated injuries, is crucial. Surgical treatment, including early ligament repair or reconstruction, may be necessary, but the optimal management approach remains controversial.
4. Tibial plateau fractures

Tibial plateau fractures can range from simple split or depression patterns to complex, bicondylar fractures. The Schatzker classification system is commonly used to describe these injuries. Treatment goals include restoring joint congruity, alignment, and stability, while managing associated soft tissue injuries. Non-operative management may be appropriate for certain patterns, while surgical treatment, such as open reduction and internal fixation or arthroscopic-assisted techniques, is often required for displaced or unstable fractures.
5. Fractures of tibial shaft

Tibial shaft fractures can occur through various mechanisms, including high-energy trauma in younger patients and low-energy injuries in the elderly. The AO/OTA classification system is used to describe these fractures. Treatment options include non-operative management with casting or bracing, as well as surgical techniques like intramedullary nailing, plate fixation, and external fixation. The choice of treatment depends on the fracture pattern, soft tissue condition, and patient factors.

1. Distal femur fracture

Distal femur fractures are serious injuries that require prompt and appropriate treatment to restore function and prevent long-term complications. These fractures often result from high-energy trauma such as motor vehicle accidents or falls from height. Careful assessment of the fracture pattern, associated injuries, and the patient's overall condition is crucial in determining the optimal treatment approach. Surgical fixation, either with plates and screws or intramedullary nails, is typically the preferred treatment to achieve stable anatomic reduction and early mobilization. Rehabilitation is essential to regain range of motion, strength, and functional independence. Potential complications include nonunion, malunion, knee stiffness, and post-traumatic osteoarthritis, which emphasize the importance of meticulous surgical technique and a comprehensive rehabilitation program. Overall, distal femur fractures require a multidisciplinary approach involving orthopedic surgeons, physical therapists, and other healthcare professionals to optimize patient outcomes.
2. Patella fracture

Patella fractures are relatively common injuries that can significantly impact a patient's mobility and function. These fractures often result from direct trauma to the knee, such as falls or motor vehicle accidents. The primary goals of treatment are to restore the extensor mechanism, maintain joint congruity, and facilitate early rehabilitation. Nondisplaced or minimally displaced fractures may be managed conservatively with immobilization and physical therapy. However, displaced or comminuted fractures typically require surgical intervention, such as open reduction and internal fixation with tension band wiring or other techniques. Careful surgical planning and execution are crucial to achieve anatomic reduction and stable fixation. Potential complications include extensor lag, patellofemoral arthritis, and loss of range of motion, emphasizing the importance of a comprehensive rehabilitation program. Overall, the management of patella fractures requires a multidisciplinary approach to optimize patient outcomes and restore functional mobility.
3. Knee dislocation

Knee dislocations are severe injuries that can result in significant morbidity and even limb-threatening complications if not managed promptly and appropriately. These injuries typically occur due to high-energy trauma, such as motor vehicle accidents or falls from height, and can involve the displacement of the femur, tibia, and/or patella relative to each other. Immediate assessment and stabilization of the joint, as well as evaluation for associated neurovascular injuries, are critical. Surgical treatment, often involving open reduction and ligamentous repair or reconstruction, is frequently required to restore joint stability and function. Rehabilitation is a crucial component of the management process, focusing on regaining range of motion, strength, and proprioception. Potential complications include persistent instability, arthrofibrosis, and post-traumatic osteoarthritis, emphasizing the need for a multidisciplinary approach involving orthopedic surgeons, physical therapists, and other healthcare professionals. Overall, the management of knee dislocations requires a comprehensive and coordinated effort to optimize patient outcomes and minimize the risk of long-term disability.
4. Tibial plateau fractures

Tibial plateau fractures are complex injuries that involve the articular surface of the proximal tibia and can significantly impact a patient's long-term function and quality of life. These fractures often result from high-energy trauma, such as motor vehicle accidents or falls from height, and can be associated with significant soft tissue injury and instability. Careful assessment of the fracture pattern, displacement, and associated injuries is crucial in determining the appropriate treatment approach. Surgical management, either with open reduction and internal fixation or minimally invasive techniques, is often necessary to restore joint congruity, maintain alignment, and facilitate early mobilization. Potential complications include post-traumatic osteoarthritis, loss of range of motion, and instability, emphasizing the importance of meticulous surgical technique and a comprehensive rehabilitation program. The management of tibial plateau fractures requires a multidisciplinary approach involving orthopedic surgeons, physical therapists, and other healthcare professionals to optimize patient outcomes and minimize the risk of long-term disability.
5. Fractures of tibial shaft

Fractures of the tibial shaft are common injuries that can significantly impact a patient's mobility and quality of life. These fractures can result from both low-energy and high-energy trauma, such as falls or motor vehicle accidents. Careful assessment of the fracture pattern, displacement, and associated injuries is crucial in determining the appropriate treatment approach. Surgical management, either with intramedullary nailing or plate fixation, is often necessary to achieve stable fixation, promote bone healing, and facilitate early mobilization. Potential complications include delayed union, nonunion, malunion, and post-traumatic osteoarthritis, emphasizing the importance of meticulous surgical technique and a comprehensive rehabilitation program. The management of tibial shaft fractures requires a multidisciplinary approach involving orthopedic surgeons, physical therapists, and other healthcare professionals to optimize patient outcomes and minimize the risk of long-term disability. Careful consideration of the patient's overall health, functional goals, and personal preferences is essential in developing the most appropriate treatment plan.
