- We prospectively randomized 233 patients with unstable trochanteric hip fractures for treatment with a 120° fixed angle blade-plate having a buttress rod (group A, n 111) or a 135° compression hip screw (group B, n 122). the minimum follow-up time was 1 year. the ratio of technical failure was 9% in group A and 19% in group B (p = 0.06). 79 (87%) fractures in group A and 65 (68%) fractures in group B healed without any complication (p = 0.003). Malunion occurred in 2 cases in group A and in 15 cases in group B (p = 0.002).

Pain drawing evaluation–the problem with the clinically biased surgeon : Intra- and interobserver agreement in 50 cases related to clinical bias
- 1998

Ingår i: Acta Orthopaedica. - : Medical Journals Sweden AB. - 1745-3674 .- 1745-3682 .- 0001-6470. ; 69:4, s. 408-411

- To assess whether the clinical knowledge of the treating surgeon had any effect on the reliability of the pain-drawing evaluation, drawings from 50 low-back pain patients were evaluated by the treating surgeon and by three colleagues who had no clinical knowledge of the patient. The evaluation was repeated after 10 days. The treating surgeons were also blinded to clinical data. The kappa value in the evaluation when the surgeon had clinical knowledge of the patient was lower (0.29 (95% CI 0.13–0.45)) than the kappa value in the evaluations made without clinical knowledge (0.60 (CI 0.45–0.75)). The differences observed in interobserver reliability between open and blind evaluations suggest that clinical knowledge of a patient influences the evaluation of the pain drawings.

Outcome of arthroscopic meniscectomy : A 13-year physical and radiographic follow-up of 43 patients under 23 years of age
- 1995
-
Ingår i: Acta Orthopaedica. - : Medical Journals Sweden AB. - 1745-3674 .- 1745-3682 .- 0001-6470. ; 66:2, s. 113-117

- We reexamined 43 patients with stable knees at a mean of 13 years after arthroscopic meniscectomy. The patients had a maximum age of 22 years at the operation and no patient had had previous surgery on the involved knee. At the follow-up examination, no differences in range of motion, muscle strength or tibial A/P displacement were seen between the operated and the nonoperated knees and 36 patients had no problem with their knee in daily life. Radiographic changes were found in the operated knee in 20 patients and in the nonoperated knee in 5 patients. 8 patients had a reduction of the joint space on the involved side, but none had more severe changes. Cartilage fibrillation at the index arthroscopy did not increase the radiographic changes at follow-up, but radiographic changes were commoner after subtotal meniscectomy (7/8) than after partial meniscectomy (17/35). These findings are similar to previous studies of arthroscopic meniscectomy of medium duration and do not differ considerably from studies of open meniscectomy.

Aggrecan degradation in osteoarthritis and rheumatoid arthritis
- 1995

- Aggrecan turnover is critically important to maintain extracellular matrix homeostasis in articular cartilage. Cartilage aggrecan metabolism has been studied in chondrocyte cell cultures, cartilage explant cultures, and in whole animal models. In many of these studies, matrix metalloproteinases (MMPs) are proposed to degrade cartilage aggrecan. MMP expression appears elevated in joint tissues from patients with osteoarthritis (OA) and rheumatoid arthritis (RA) (Dean et al. 1989, Wolfe et al. 1993) and inhibitors of both MMPs and thiol proteinases have been shown to block aggrecan (Buttle et al. 1992) and type II collagen (Mort et al. 1993) degradation in cartilage explant cultures. Using antibodies and cDNA probes, elevations in expression and concentration of many of these enzymes in animal models and in OA and RA have been described. Human cartilage aggrecan has now been cloned and sequenced (Doege et al. 1991). This information, in combination with the ability to sequence aggrecan and aggrecan fragments at the protein level, has resulted in the identification of several aggrecan fragments which appear to result from proteinase degradation. In this report, we describe data which suggest that MMPs may in part be responsible for aggrecan catabolism in normal articular cartilage, as well as in the elevated catabolism seen in OA and RA.

- All players in Swedish soccer teams are required to have insurance in the same company. from the archives of the insurance company, all 3,735 injuries reported in 1986 in 188,152 Swedish soccer players were reviewed. of these, 937 were knee injuries. All players were asked by mail to fill in a questionnaire and 83 percent replied. the patient records from the different hospitals were requested. the anterior cruciate injuries represented one third of the reported knee injuries. the relative risk of sustaining an anterior cruciate ligament Injury was increased in female players, in elite players, and in players in the forward position. the odds ratios were 1.6 (1.3-2.1), 3.3 (1.7-6.1) and 1.8 (1.4-2.5), respectively. the injuries occurred at a younger age in females than in males. 50 percent of the injured players were treated with anterior cruciate ligament surgery, predominantly as a reconstructive procedure, with use of a patellar tendon transplant. 30 (20) percent of the players with anterior cruciate ligament injury were active in soccer after 3 (7) years, compared to 80 (50) percent of an uninjured control population of soccer players. None of the elite players was active at the same level after 7 years. A comparison of anterior cruciate ligament-injured players, whether treated by surgical reconstruction or not, revealed no difference with regard to the proportion of players still playing soccer after 7 years.
