knee injuries occur following trauma or fall. Knee is a major weight bearing joint and the knee injuries require proper management with appropriate treatment. Following are few xrays of knee injuries and other conditions of the knee.
Image I – Knee Xray Showing Fracture Patella
The image in the view shows lateral view of the knee joint. The xray shows fracture of patella bone. Patella is the bone that is present on anterior aspect of knee. It is also called knee cap.
Fracture of patella is commonly associated with rupture of quadriceps mechanism which results in inability to extend the knee.
Patellar fractures are quite common injuries and frequently require surgical fixation.
The patient in present image suffered this injury after he tripped on banana peel. The patient has been operated with tension band wiring and is mobile with crutches now.
Image 2 – Xray of United Fracture Distal Femur With Condylar Plate In Situ
Distal femur fractures are also called intercondylar fractures and supracondylar fractures. Former are intra-articular injuries and often need surgical stabilization.
This is an xray of patient who was treated surgically for intercondylar fractures with use of condylar plate as implant.
The fracture has united very well and articular congruity is very well maintained.
Image 3 – Supracondylar Fracture Of Femur – Anteroposterior Xray
This fracture was sustained by a 47 years old bike driver in a rad traffic accident.
Interestingly, the patient refused the surgery and was treated with traction.
Image 4 – Knee xray Showing Fracture Shaft Of Femur With Ipsilateral Medial Condyle Tibia Fracture
Concomitant fractures of tibia and femur are increasing due to increase in motor vehicular trauma. The following images are radiographs of a young man who suffered from injury to his femur and tibia when his bike struck with an auto-rickshaw and he was toppled over.
Following xray is of the thigh bone. A fracture in middle third – lower third is visible along with a butterfly fragment.
Here is xray of his knee and leg revealing medial condyle fracture of tibia.
The person was treated with interlock nailing for femur and condylar plating for tibia.

The fracture fragments are widely displaced and require tension band wiring.
Image 8 – Lateral View of Knee Showing Broken Stainless Steel Circlage Wire In United Fracture Patella
Lateral view of united fracture patella showing a broken stain steel circlage wire.
The circlage was done two years back for fracture of patella which is well united on this xray.
The implant was removed.
Image 9 – Comminuted Distal Third Femur Fracture Fixed By Distal Femur Plate
Sixty five years old lady presented with history of injury three months back operated at a distant place. She gave a history of fracture in femur which had been fixed.
Her latest xray showed comminuted fracture of distal femur fixed by distal femoral plate.
The fracture had still not united. She was advised bone grafting but never followed up.
Image 10 -Xray of Fracture of Distal Femur
Following xray of is of 24 years old male patient who suffered injury following a motor vehicle injury. The xray reveals a distal femoral fracture in intercondylar and supcondylar region.
There was no neurovascular deficit. The patient was splinted and advised fixation of fracture but patient chose not to get operated.
Image 11 – Xray of Oblique Fracture Femur In Supracondylar Region
Following xray is of 42 years old lady with fracture of supracondylar region of femur. The patient had post polio residual paralysis in the limb and also had about 60 degree flexion deformity prior to injury.
The patient was suggested open reduction and internal fixation for the fracture but she chose not to get operated. The limb was splinted with posterior slab in same flexion deformity.
Image 12 – Knee Xray with Loose Bodies in Knee With Osteoarthritis
Loose bodies in knee may be found in osteoarthritis and represent a loose [unattached to any tissue] piece of bone or cartilage or any other foreign object.
Following xray belongs to 56 years old lady who complained of knee pain that aggravated with walking. Loose bodies are visible.
She was advised arthroscopic removal of the loose body.
Image 13 – Xray of Comminuted Fracture of Patella
The xray in the image belongs to 23 year old man who sustained a fall from motorbike . The xray is lateral view of the knee and shows comminuted fracture of the patella.
The patient was operated with tension band wiring and has recovered uneventfully.
Image 14 – Xray of Undisplaced Transverse Fracture of Patella
Patella fracture is a very common injury. The xray shows a transverse undisplaced fracture of patella in 44 years old man. The fracture of patella is usually not visible in anteropsterior view. The fracture was treated in a cylinder cast.
Undisplaced fractures of patella are usually amenable to non operative treatment.
Image 15 – Xray of Bilateral Medial Compartment Osteoarthritis of knee
Osteoarthritis of knee is very common problem in Asian region. The disease typically starts in medial compartment of the knee and then progresses to all the compartments.
The xray belongs to a lady of 49 years old whose main complaint was pain on climbing stairs. An xray doen revealed bilateral medial compartment involvement.
The patient is being managed on conservative treatment.
Image 16 – Fracture Of Medial Condyle Of Right Femur – Anteroposterior and Lateral Xray
Xrays of condyles of femur are common injuries. Lateral condyle injuries are more common as compared to medial condyle. If undisplaced the medial condyle fractures can be managed by non operative means. Displaced fractures require open reduction and internal fixation.
Following xray belongs to a 39 years old male who got injured following fall from bicycle.
The fracture is marked by arrows in both the views.
The fracture was managed with above knee cast.

Xray of knee showing fracture of patella in an adult male who got injured in a motor vehicle accident.
Image 22 – Xray of Hoffa Fracture
Hoffa fracture is fracture of femoral condyle in coronal plane [a plane that divides the body into front and back half]. This xray is of 33 years old male who injured his knee in an accident.
The xray is lateral view and the condyle involved was lateral femoral condyle.
The fracture was operated by open reduction and internal fixation and used 2 cannulated cancellous screws for fixation of the fracture.
Here is a Carm view after fixation
This kind of fracture requires open reduction and internal fixation in form of tension band wiring.
