TL;DR: The method described in this article is applicable irrespective of the details of the diagnostic or radiologic abnormalities caused by disease or injury and is accurately reproducible by different observers and is sufficiently sensitive to reveal even small changes in function.
Abstract: Several methods have been devised to estimate shoulder function, none of which is entirely satisfactory. The method described in this article is applicable irrespective of the details of the diagnostic or radiologic abnormalities caused by disease or injury. The method records individual parameters and provides an overall clinical functional assessment. It is accurately reproducible by different observers and is sufficiently sensitive to reveal even small changes in function. The method is easy to perform and requires a minimal amount of time for evaluation of large population groups.

TL;DR: A new total knee rating system has been developed by The Knee Society to provide an up-to-date more stringent evaluation form and eliminates the problem of declining knee scores associated with patient infirmity.
Abstract: A new total knee rating system has been developed by The Knee Society to provide an up-to-date more stringent evaluation form. The system is subdivided into a knee score that rates only the knee joint itself and a functional score that rates the patient's ability to walk and climb stairs. The dual rating system eliminates the problem of declining knee scores associated with patient infirmity.

TL;DR: In view of the increasing incidence of stem-type femoral component loosening, a detailed retrospective radiographic zonal analysis of 389 total hip replacements indicated a 19.5% incidence of radiological evidences of mechanical looseness, i.e., fractured acrylic cement and/or a radiolucent gap at the stem-cement or cement-bone interfaces.
Abstract: In view of the increasing incidence of stem-type femoral component loosening, a detailed retrospective radiographic zonal analysis of 389 total hip replacements indicated a 19.5% incidence (76 hips) of radiological evidences of mechanical looseness, i.e., fractured acrylic cement and/or a radiolucent gap at the stem-cement or cement-bone interfaces. Detailed serial radiographic examination demonstrated progressive loosening in 56 of the 76 hips and these were categorized into mechanical modes of failure. The 4 modes of failure characterizing stem-type component progressive loosening mechanisms consisted of stem pistoning within the acrylic (3.3%), cement-embedded stem pistoning with the femur (5.1%), medial midstem pivot (2.5%), calcar pivot (0.7%) and bending (fatigue) cantilever (3.3%).

TL;DR: A new activity grading scale, where work and sport activities were graded numerically, was constructed as complement to the functional score, showing that the symptom-related score gave a more differentiated picture of the disability.
Abstract: Many different methods of evaluating disability after knee ligament injury exist. Most of them differ in design. Some are based on only patients' symptoms. Other include patients' symptoms, activity grading, performance in a test, and clinical findings. The rating in these evaluating systems can be either numerical, as in a score, or binary, with yes/no answers. Comparison between a symptom-related score and a score of more complex design showed that the symptom-related score gave a more differentiated picture of the disability. It was also shown that the binary rating system gave less detailed information than a score and that differences in a binary rating can depend on at what level the symptoms are regarded as "significant." A new activity grading scale, where work and sport activities were graded numerically, was constructed as complement to the functional score. When evaluating knee ligament injuries, stability testing, functional knee score, performance test, and activity grading are all important. However, the relative importance varies during the course of treatment, and therefore they should not all be included in one and the same score.

TL;DR: The fact that nearly 30 per cent of cases showed no demarcation even after 10 years supports the idea that there is no fundamental defect in the principle of employing cement in the acetabulum.
Abstract: The frequency of radiological demarcation of the cement-bone junction in the acetabulum after total hip replacement has been examined in 141 Charnley low-friction arthroplasties followed for an average of 10.1 years. Sixty-nine per cent showed demarcation of various degrees and 9.2 per cent of the series showed evidence of progressive migration of the socket. The vast majority of cases with demarcation were symptomless. In most cases where demarcation was accompanied by migration the operation notes suggested a technical explanation and in three cases low-grade sepsis was responsible. The fact that nearly 30 per cent of cases showed no demarcation even after 10 years supports the idea that there is no fundamental defect in the principle of employing cement in the acetabulum. Better surgical technique may increase the number of cases showing no demarcation.
