- There is broad consensus that good outcome measures are needed to distinguish interventions that are effective from those that are not. This task requires standardized, patient-centered measures that can be administered at a low cost. We developed a questionnaire to assess short- and long-term patient-relevant outcomes following knee injury, based on the WOMAC Osteoarthritis Index, a literature review, an expert panel, and a pilot study. The Knee Injury and Osteoarthritis Outcome Score (KOOS) is self- administered and assesses five outcomes: pain, symptoms, activities of daily living, sport and recreation function, and knee-related quality of life. In this clinical study, the KOOS proved reliable, responsive to surgery and physical therapy, and valid for patients undergoing anterior cruciate ligament reconstruction. The KOOS meets basic criteria of outcome measures and can be used to evaluate the course of knee injury and treatment outcome.

- The Knee injury and Osteoarthritis Outcome Score (KOOS) is a self-administered instrument measuring outcome after knee injury at impairment, disability, and handicap level in five subscales. Reliability, validity, and responsiveness of a Swedish version was assessed in 142 patients who underwent arthroscopy because of injury to the menisci, anterior cruciate ligament, or cartilage of the knee. The clinimetric properties were found to be good and comparable to the American version of the KOOS. Comparison to the Short Form-36 and the Lysholm knee scoring scale revealed expected correlations and construct validity. Item by item, symptoms and functional limitations were compared between diagnostic groups. High responsiveness was found three months after arthroscopic partial meniscectomy for all subscales but Activities of Daily Living.

- Objective: To compare the sensitivity of WOMAC and the two added dimensions Sport and Recreation Function and Knee Related Quality of Life in subjects with radiographic knee OA to that in controls. To study the influence of age on the reported outcomes. Design: Outcomes were compared between subjects having had meniscectomy 21 years ago and which at time of follow-up had definite radiographic OA (N=41, mean age 57), and age- and sex- matched controls without radiographic OA (N=50, mean age 53). For the purpose of studying the impact of age, the groups were divided in two age groups, younger and older than 50 years, respectively. Close to 50% of both groups reported current physical activity levels of at least recreational golf, dancing, hiking, etc. Symptoms and function were assessed by WOMAC Osteoarthritis Index and the added dimensions Sport and Recreational Function (Sport/Rec) and Knee Related Quality of Life (QOL). A percentage score was calculated, 0 indicating extreme knee problems and 100 indicating no knee problems. Results: The control group had mean scores of 88-98 for the different dimensions. The OA group scored significantly lower in all dimensions (P

- Objective. To study the long-term outcome of surgical removal of a meniscus in the knee with regard to radiographic signs of osteoarthritis (OA). Methods. Of the 123 patients who underwent an open meniscectomy due to an isolated meniscus tear in 1973 at Lund University Hospital, 107 were followed up 21 years later by clinical examination and by review of knee radiographs obtained with weight bearing. Seventy-nine of the 107 patients were men, and the mean age of the total study group at examination was 55 years (range 35-77). Sixty-eight sex- and age-matched individuals with healthy knees served as controls. Results. Mild radiographic changes were found in 76 (71%) of the knees, while more advanced changes, comparable with a Kellgren-Lawrence grade of 2 or higher, were seen in 51 (48%). The corresponding prevalence values in the control group were 12 (18%) and 5 (7%), respectively. The relative risk for the presence of the more advanced radiographic changes representing definite radiographic tibiofemoral OA was 14.0 (95% confidence interval 3.5-121.2), using age- and sex-matched pairs for comparison. No correlation with sex, localization to compartment, type of meniscus tear, or work load was found. Knee symptoms were reported twice as often in the study group as in the controls. Conclusion. Surgical removal of a meniscus following knee injury represents a significant risk factor for radiographic tibiofemoral OA, with a relative risk of 14.0 after 21 years.

Frequency-resolved time-gated high-order harmonics

- We report measurements of high-order harmonic spectra obtained with a 800-nm 150-fs loser pulse with a time-varying degree of ellipticity. The modulation of the polarization in time is achieved by using birefringent optics and self-phase modulation in a glass plate. We can create one or two temporal gates of a few femtoseconds width, during which the polarization is linear and harmonic emission is efficient. The harmonic spectra observed experimentally demonstrate that harmonics generated with linear polarization are frequency chirped. The values measured experimentally are consistent with theoretical predictions based on the strong field approximation. [S1050-2947(98)05511-5].

- The products of the reaction of Sc and dioxygen have been reinvestigated. By adding the electron-trapping molecule CCl4 additional information about the IR spectra has been obtained, as well as the observation of new bands. New ab initio calculations are also performed on possible products of the Sc plus O-2 reaction. The previously observed band at 722.5 cm(-1) is assigned as the b(2) mode of ScO2-. Bands arising from ScO+, Sc(O-2)(+), and(O-2)ScO are also assigned. We are still unable to assign any bands to OScO. The problems associated with the computational study of ScO2 are discussed.
