Patella fracture; Other names: Broken kneecap: A fracture of the patella seen on a lateral view: Specialty: Orthopedics: Symptoms: Pain, swelling, bruising to front of the knee [1] Complications: Injury to the tibia, femur, or knee ligaments [2] Types: Stable, displaced, comminuted, open [1] Causes: Trauma to the front of the knee [1 ...
This is a shortened version of the thirteenth chapter of the ICD-9: Diseases of the Musculoskeletal System and Connective Tissue. It covers ICD codes 710 to 739 . The full chapter can be found on pages 395 to 415 of Volume 1, which contains all (sub)categories of the ICD-9.
Patellar tendon rupture can usually be diagnosed by physical examination. The most common signs are: tenderness, the tendon's loss of tone, loss of ability to raise the straight leg and observation of the high-riding patella. Radiographically, patella alta can be detected using the Insall and Salvati method when the patella is shorter than its ...
[6] [4] Surgery may be indicated in those cases where a fracture occurs within the joint or where the patella has repeatedly dislocated. [3] [4] [5] Patellar dislocations occur in about 6 per 100,000 people per year. [4] They make up about 2% of knee injuries. [1] It is most common in those 10 to 17 years old. [4] Rates in males and females are ...
The patella rests in the trochlear, which is found in the distal part of the femur. The patella can dislocate from the groove because of trauma or an unnatural twisting of the knee. [5] When dislocated, the soft tissue layer that the patella rests in is damaged; the patella is forced out of its groove and back into place.
With the patient supine and the knees flexed 30° off the table, stabilize the thigh and externally rotate the foot. As the foot rotates, watch for external rotation of the tibial tubercle of the affected knee compared to the healthy one. A difference of greater than 10-15° indicates a positive test and likely injuries to the posterolateral knee.
The osteochondral fracture occurs on the weight-bearing portion of the lateral condyle. Typically, the condyle will fracture (and the patella may dislocate) as a result of severe impaction from activities such as downhill skiing and parachuting. [1] Open reduction and internal fixation surgery is typically used to repair an osteochondral fracture.
Stress fractures most frequently occur in weight-bearing bones of the lower extremities, such as the tibia and fibula (bones of the lower leg), metatarsal and navicular bones (bones of the foot). Less common are stress fractures to the femur, pelvis, and sacrum. Treatment usually consists of rest followed by a gradual return to exercise over a ...
