Proto-oncogene expression in cultured synovial fibroblasts of patients with rheumatoid arthritis

Total RNA was isolated from cultured synovial fibroblasts of nine patients with rheumatoid arthritis and two controls (cruciate ligament ruptures). RNA was dot-blotted and hybridized with nine different, cloned cellular or viral oncogene probes. None of the proto-oncogenes showed a significant difference of expression in cultured fibroblasts from patients with rheumatoid arthritis when compared to the expression of control fibroblasts.

Active knee motion after cruciate ligament rupture

Active knee motion after cruciate ligament rupture. Stereoradiography.

In 10 patients with an old injury of the anterior cruciate ligament, the three-dimensional movements of the knee joint were studied when the patients flexed their knees. Tibial motions were recorded using roentgen stereophotogrammetric analysis. Internal rotation and adduction of the tibia were reduced in the injured knees when compared with the intact knees; during flexion of the knee joint, the tibial intercondylar eminence occupied a more lateral and posterior position on the injured side. Our results may indicate that the knee joint is continuously exposed to abnormal stresses when the anterior cruciate ligament is torn.

Surgical Management of Multiple Ligamentous Injuries of the Feline Stifle Joint: Case Report

We report a case of complete rupture of the tendon of origin of the long digital extensor at the myotendinous junction, with concurrent ruptures of the posterior cruciate and lateral collateral ligaments in the stifle joint of a cat. Stabilization was accomplished by direct suturing of the long digital extensor injury, imbrication of the joint capsule and lateral retinacular fascia, and creation of a synthetic lateral collateral ligament

Stress radiographical measurements of post-traumatic knee instability. A clinical study.

In a prospective, consecutive, clinical and stress radiographical study, comprising 153 traumatic knee injuries, the value of stress radiographical measurements, gonylaxometry, was studied. Clinical evaluation, gonylaxometry and preoperative evaluation under general anaesthesia were carried out in that order. Then the operative findings were recorded as drawings on standard diagrams. These were used as a basis for evaluation of the preoperative tests. Of all the methods evaluated, gonylaxometry was found to provide the most accurate information regarding the knee injury. Very close to this result were the findings under general anaesthesia. Anterior drawer sign was measured gonylaxometrically when damage to the anterior cruciate ligament was present; posterior drawer meant damage to the posterior cruciate ligament. Partial ruptures of cruciate ligaments did not allow antero-posterior displacements exceeding the critical levels of the test. Small positive medial instability was found with ruptures of profound medial structures, higher values with total rupture of the long superficial collateral band, and still higher values when cruciate ligament ruptures were also present. The predictive values of a positive radiographical test were 100 per cent as regards medial instability and 98 per cent for drawer looseness. The predictive values of a negative test were 96 per cent for drawer and 92 per cent for medial instability. These figures are based on the total material. 95 per cent confidence limits are given.
