The use of stereolithography for an unusual patellofemoral disorder.

A patient with habitual patellar dislocation which was not treated successfully by the Elmslie-Trillat procedure is described. In the knee, a unique morphologic feature of the patellofemoral joint was suspected as a cause, and a stereolithographic model was produced from the patient's computed tomography data to determine the pathologic features. Because the solid model confirmed the speculation, additional surgery was done to modify the geometry of the joint. In the surgery, cancellous bone was removed below the cartilage, and the geometry of the cartilage was modified with the subchondral bone, taking advantage of the elasticity of the bone and cartilage. The second surgery eliminated maltracking of the patella and a satisfactory result was obtained. Therefore, stereolithography is useful for the treatment of atypical patellofemoral disorders, allowing an understanding of the pathologic features and dynamic simulation of the surgery. The surgical procedure could be a promising method to alter the joint geometry without impairing the cartilage.

The importance of soft tissues in certain skeletal traumatic lesions.

Soft tissue aspects of skeletal trauma are discussed according to two categories: (1) those injuries in which the significance of the soft tissue in the pathophysiology of the skeletal lesion is indicated by the characteristics of the skeletal injury (such as extension teardrop fracture, little leaguer's elbow, "baseball fracture," and Bennett's fracture); and (2) those injuries in which the associated soft tissue injury, or complication, may be reasonably inferred by the location and nature of the skeletal injury (such as major facial fractures, posterior sternoclavicular dislocations, fractures of the lower rib and lumbar transverse processes, and pelvic disruptions).

[Injuries of the major blood vessels in joint dislocations].

Experience with the treatment of 12 patients with injuries of major vessels resulting from dislocations of joints is generalized. In 5 of the patients an associated injury of nerve trunks was diagnosed, in 4 patients there were injuries of major veins. Reconstructive operations were made in 11 patients. In 8 patients full recovery was stated, three patients were subjected to amputation of the extremity. The main cause of the failure was late diagnosis of the closed trauma of the artery and progressing ischemia of the extremity.

Ligamentous laxity and scar formation.

The character of scar tissue is relative to or influenced by ligamentous laxity. Patients who are able to passively hyperextend the terminal interphalangeal joint of the index finger to 45 degrees and beyond have a tendency to leave broad scars. This proved to be statistically significance (p less than .001). It is suggested that in female patients in particular, assessment of the passive hyperextensibility of the terminal interphalangeal joint of the index finger can be used preoperatively to determine whether the patient will be left with a cosmetically displeasing scar following any operative procedure.

Knee joint in soccer players: osteoarthritis and axis deviation.

The knee joints of 81 veteran soccer players between ages 40 and 74 were examined. An analysis of and relationships between soccer practice at a top level, osteoarthritis, meniscectomy, and leg axes were evaluated. One-hundred and sixty-two knees were assessed through clinical examination and X-ray examination using a large table in order to observe the entire lower extremity's axis in weight bearing. First, it appears that radiological signs of osteoarthritis in soccer players increase with age in a much greater percentage than in a random population of the same age. Second, all players who have had a meniscectomy presented with radiological signs of osteoarthritis. In this series, 91 knees (56%) had X-ray signs of osteoarthritis. 64 knees (70%) in which the roentgenograms showed significant osteoarthritic changes were clinically asymptomatic. Third, the lower extremities displayed a varus angulation of both knees in 73% (meaning that 59 veteran players have a varus of both legs), while 81% of all the knees showed a varus deviation.
