Identifying Knee Osteoarthritis: Classification, early recognition and imaging
Osteoarthritis (OA) is one of the most frequently
occurring health problems in middle aged and older
people. Treatment of OA is focused on treating
symptoms while it might be more effective to start
treatment before symptoms are present. Early
predictive signs for evident knee OA need to be
identified, so it will be possible to define people that
will get OA in the future. This thesis describes the
evaluation of different classification criteria and the
identification of radiographic and MRI features that
are related to different aspects of clinical symptoms
and risk factors of (early) knee O
344 RISK FACTORS AND SYMPTOMS OF RADIOLOGICAL KNEE OSTEOARTHRITIS: DOES BMI MAKE A DIFFERENCE?
Towards sex-specific osteoarthritis risk models: evaluation of risk factors for knee osteoarthritis in males and females
Objectives The aim of this study was to identify sex-specific prevalence and strength of risk factors for the incidence of radiographic knee OA (incRKOA). Methods Our study population consisted of 10 958 Rotterdam Study participants free of knee OA in one or both knees at baseline. One thousand and sixty-four participants developed RKOA after a median follow-up time of 9.6 years. We estimated the association between each available risk factor and incRKOA using sex stratified multivariate regression models with generalized estimating equations. Subsequently, we statistically tested sex differences between risk estimates and calculated the population attributable fractions (PAFs) for modifiable risk factors. Results The prevalence of the investigated risk factors was, in general, higher in women compared with men, except that alcohol intake and smoking were higher in men and high BMI showed equal prevalence. We found significantly different risk estimates between men and women: high level of physical activity [relative risk (RR) 1.76 (95% CI: 1.29–2.40)] or a Kellgren and Lawrence score 1 at baseline [RR 5.48 (95% CI: 4.51–6.65)] was higher in men. Among borderline significantly different risk estimates was BMI ≥27, associated with higher risk for incRKOA in women [RR 2.00 (95% CI: 1.74–2.31)]. The PAF for higher BMI was 25.6% in women and 19.3% in men. Conclusion We found sex-specific differences in both presence and relative risk of several risk factors for incRKOA. Especially BMI, a modifiable risk factor, impacts women more strongly than men. These risk factors can be used in the development of personalized prevention strategies and in building sex-specific prediction tools to identify high risk profile patients
Knee joint bone shape is related to BMI but only marginally to early signs of knee osteoarthritis in healthy middle-aged women
Patterns of knee osteoarthritis management in general practice:a retrospective cohort study using electronic health records
Objective: This study determined patterns of knee osteoarthritis (OA) management by general practitioners (GPs) using routine healthcare data from Dutch general practices from 2011 to 2019. Design: A retrospective cohort study was conducted using the Integrated Primary Care Information database between 2011 and 2019. Electronic health records (EHRs) of n = 750 randomly selected knee OA patients (with either codified or narrative diagnosis) were reviewed against eligibility criteria and n = 503 patients were included. Recorded information was extracted on GPs’ management from six months before to three years after diagnosis and patterns of management were analysed.Results: An X-ray referral was the most widely recorded management modality (63.2%). The next most widely recorded management modalities were a referral to secondary care (56.1%) and medication prescription or advice (48.3%). Records of recommendation of/referral to other primary care practitioners (e.g. physiotherapists) were found in only one third of the patients. Advice to lose weight was least common (1.2%). Records of medication prescriptions or recommendation of/referral to other primary care practitioners were found more frequently in patients with an X-ray referral compared to patients without, while records of secondary care referrals were found less frequently. Records of an X-ray referral were often found in narratively diagnosed knee OA patients before GPs recorded a code for knee OA in their EHR. Conclusion: These findings emphasize the importance of better implementing non-surgical management of knee OA in general practice and on initiatives for reducing the overuse of X-rays for diagnosing knee OA in general practice.</p

Opioid prescriptions in patients with osteoarthritis: a population-based cohort study
OBJECTIVES: To examine the incidence, prevalence and trends for opioid prescriptions in patients with OA. Furthermore, types of opioids prescribed and long-term prescription rates were examined. Finally, the patient characteristics associated with the prescription of opioids wer
Best evidence osteoarthritis care: What are the recommendations and what Is needed to improve practice?
This article provides an overview of osteoarthritis (OA) management recommendations and strategies to improve clinical practice concordance with clinical guidelines. In many countries, the primary point of care for a person with OA is typically general practitioners and physiotherapists. Optimal primary care focuses on core OA treatments, namely education for self-management and lifestyle interventions encompassing increased physical activity, therapeutic exercise, and weight loss (if indicated). Quality indicators are used in clinical practice and research to determine the quality of care and in some settings, are used as knowledge translation tools to address existing evidence-to-practice gaps
Prevalence of small osteophytes on knee MRI in several large clinical and population-based studies of various age groups and OA risk factors
Objective: Osteophytes, also small ones, are an important imaging feature of OA. However, due to their high prevalence on MR, the question has arisen whether these are truly pathophysiologic features of early OA, a result of physiologic aging, or rather a merely transient phenomenon. The aim of this study was to explore the prevalence of osteophytes on MR in various locations of the knee, with special emphasis on small osteophytes, across multiple large studies conducted in our institution comprising a wide range of subjects at different ages. Method: Retrospective explorative study of the prevalence of osteophytes, particularly grade 1 according to MOAKS, among four studies with a wide variety in age and OA risk factors. Results: A large number of grade 1 osteophytes were found in all four studies. The largest number of osteophytes were present in the youngest age group of <30 years (69.6%) compared to 36.8% in the age group of ≥30 ​< ​50 years and 54,3% when aged ≥50 years, of which most were grade 1 osteophytes. Conclusion: Small osteophytes are highly prevalent among populations with varying age and OA risk factors, in particular among young subjects without other OA features. This might suggest that these “osteophytes” do not necessarily represent early OA, but rather indicate a transient physiologic phenomenon.</p
