Int J Rheum Dis 2023; 26:1722-1728. [PMID: 37358256 DOI: 10.1111/1756-185x.14800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 05/05/2023] [Accepted: 06/13/2023] [Indexed: 06/27/2023]
Abstract
OBJECTIVE To investigate whether baseline joint space narrowing (JSN) predicted disease remission, knee pain, and physical function changes in persons with knee osteoarthritis (OA). METHODS This study is a secondary analysis of a two-armed randomized controlled trial. Participants were aged ≥50 years (n = 171) with a body mass index ≥28 kg/m2 and radiographic medial tibiofemoral OA. Participants in the intervention group received diet and exercise programs and special treatment (cognitive behavioral therapy, knee brace, and muscle strengthening exercises) according to the disease remission. Remission of pain and remission of patient global assessment of disease activity and/or functional impairment were used to define the disease remission. The control group were provided with an education pamphlet. The primary outcome was disease remission at 32 weeks, and the secondary outcomes were the changes in knee pain and physical function at 20 and 32 weeks. Baseline JSN was scored from 0 to 3, and the association between baseline JSN and outcomes was assessed using multiple regression. RESULTS There was no association of baseline JSN with disease remission at 32 weeks when the disease remission has been achieved. The baseline JSN grade 3 was associated with changes in knee pain at 20 weeks (p < .05). There was no association between baseline JSN and physical function. CONCLUSION Baseline JSN severity predicted changes in knee pain but not the disease remission or changes in physical functions. Identification of baseline radiographic severity may be helpful in identifying differences in response to diet and exercise programs in knee OA.

[PMID: 36572505 DOI: 10.1111/1756-185x.14536] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 11/15/2022] [Accepted: 12/02/2022] [Indexed: 12/28/2022]
Abstract
INTRODUCTION Subjective knee stiffness is a common symptom in patients with knee osteoarthritis treated conservatively. However, the influencing factors or effects of knee joint stiffness are unknown. The aim of this study was to explore the factors associated with subjective knee stiffness in patients with knee osteoarthritis. METHODS The MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, Cumulative Index to Nursing and Allied Health Literature, Web of Science, and PEDro databases were searched in November 2021. Prospective or retrospective cohort studies were included. The methodological quality of the selected articles was assessed using the Scottish Intercollegiate Guidelines Network checklist. RESULTS Twenty out of 1943 screened articles were included in this systematic review. Eighteen and two studies were rated as having acceptable and low quality, respectively. All the included studies measured subjective knee stiffness using the Western Ontario and McMaster Universities Osteoarthritis Index. The main findings were that worse preoperative subjective knee stiffness was associated with worse pain, subjective knee stiffness, and patient satisfaction at 1 year after total knee arthroplasty. In addition, worse subjective knee stiffness was associated with future degenerative changes in the knee joint, such as joint space narrowing and osteophyte growth progression. CONCLUSION Subjective knee stiffness may be associated with the prognosis after total knee arthroplasty and degenerative changes in the knee joint. Early detection and treatment of knee stiffness could lead to a good prognosis after total knee arthroplasty and prevent the progression of degenerative changes in the knee joint.

Abstract
BACKGROUND Osteoarthritis of the knee is a chronic inflammatory condition resulting in significant patient disability, with intra-articular platelet rich plasma (PRP) injections having shown potential to improve symptomatic outcomes. This retrospective cohort pilot study aimed to observe whether PRP injections were beneficial in the symptomatic management of knee osteoarthritis in an Australian population, based on patient reported outcomes. An additional aim was to observe for an association between the number of injections and patient characteristics, such as body mass index, age, sex and radiologically determined severity of the disease. METHODS The cohort was drawn from those who attended Ballarat Orthopaedic and Sports Medicine for PRP injections and who had completed the appropriate pre- and post-injection Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire. WOMAC scores were analysed to observe for any difference following a course of PRP injections. RESULTS The data suggest that the use of PRP improved patient reported WOMAC scores. Additionally, it was shown that two injections had a greater effect than one injection, with a third injection providing no further benefit. Finally, there was an association with lower WOMAC scores post PRP therapy amongst male participants compared to female participants. CONCLUSION These results suggest two PRP injections are optimal for the symptomatic management of knee osteoarthritis, identifying a need for further prospective research in this Australian population.

Abstract
OBJECTIVE The purpose of this study is to assess if incident radiographic osteoarthritis (OA) is associated with clinical OA symptoms at midterm follow-up after arthroscopic partial medial meniscectomy (APMM). DESIGN A total of 44 patients (43% females, mean age 50.1 ± 2.8 years, minimum 5.6-year follow-up) with isolated medial meniscal tears and no-to-mild preoperative radiographic OA underwent APMM. Incident radiographic OA was assessed using the modified Kellgren-Lawrence (K-L) classification. Patients completed the Knee Injury and Osteoarthritis Outcomes Score (KOOS), and subscale thresholds for assessment of a symptomatic knee (KOOS OA criteria) and for Patient non-Acceptable Symptom State (PASS-N) following anterior cruciate ligament reconstruction (ACL-R) were calculated. RESULTS Incident medial compartment OA occurred in 50% of patients. Morbidly obese patients (body mass index ≥35 kg/m2) were more likely to demonstrate incident radiographic OA (100% vs. 41%, P = 0.002). Forty-three percent of patients met KOOS OA criteria, while 77% were PASS-N. Females were more likely to meet KOOS OA criteria (73% vs. 21%, P = 0.009). Patients with incident radiographic OA in any compartment were more likely than those without radiographic OA to meet KOOS OA criteria (71% vs. 17%, P = 0.008). Patients with preoperative K-L grade 2 changes in any compartment were more likely to meet KOOS OA criteria than those without K-L grade 2 changes in any compartment (83% vs. 35%, P = 0.037). CONCLUSIONS Roughly half of APMM patients will have incident radiographic OA within 6 years of APMM, and this risk increases with obesity. Females and patients with incident radiographic OA are more likely to meet clinical thresholds for OA.

The presence of erosive joints is a strong predictor of radiological progression in hand osteoarthritis: results of a 2-year prospective follow-up of the Liège Hand Osteoarthritis Cohort (LIHOC). Arthritis Res Ther 2021; 23:12. [PMID: 33407767 PMCID: PMC7788934 DOI: 10.1186/s13075-020-02390-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Accepted: 12/09/2020] [Indexed: 11/10/2022] Open
Abstract
Background This study measured the magnitude and determinants of clinical and radiological progression in patients with hand osteoarthritis (HOA) over a 2-year prospective follow-up to gain a greater understanding of the disease time course. Methods Two hundred three consecutive outpatients diagnosed with HOA were followed for 2 years (183 women, median age 69 years). Pain and function were evaluated using the Australian/Canadian Osteoarthritis Hand Index (AUSCAN), and clinical examination recorded the number of painful/swollen joints and nodes. X-rays were scored using Kellgren-Lawrence (KL) and Verbruggen-Veys scales. Clinical progression was defined as deterioration in AUSCAN ≥ the minimal clinically important difference. Radiographic progression was defined as (a) one new erosive/remodeled joint, (b) progression of ≥ one anatomical stage in one joint, or (c) change in KL total score above the smallest detectable difference. Logistic regression was performed to determine whether patient characteristics influenced clinical and radiological progression. Results After 2 years, all radiographic scores deteriorated significantly in the study population (p < 0.05), and the number of proximal and distal interphalangeal nodes was significantly higher (p < 0.01). The AUSCAN, number of painful joints at rest or at pressure, number of swollen joints, and pain measure on a visual analog scale remained unchanged. At the individual level, the number of patients with clinically meaningful progression ranged from 25 to 42% (clinical progression) and from 22 to 76% (radiological progression). The only significant predictor of worsening of total AUSCAN was AUSCAN pain subscale < 74.5 (odds ratio [OR] 1.02 [1.01, 1.03]; p < 0.01). The presence of ≥ four swollen joints (OR 2.78 [1.21, 6.39]; p = 0.02) and erosive osteoarthritis (OR 13.23 [5.07, 34.56]; p < 0.01) at baseline predicted a new erosive joint. A meaningful change in KL was more frequent with painful joints at baseline (OR 3.43 [1.68, 7.01]; p < 0.01). Conclusions Evidence of radiological progression over 2 years was observed in patients with HOA in the LIHOC population even without clinical worsening of disease. For individual patients, baseline pain level is predictive for clinical progression and the presence of erosive or swollen joints are significant predictors of radiological progression.

Abstract
PURPOSE The purpose of this study was to assess the impact of developed minimally invasive operation such as the partial lateral facetectomy (PLFE) with patella thickness resection in patients with lateral patellofemoral (PF) osteoarthritis on short-term clinical and radiographic outcomes. METHODS This is a prospective study of 27 knees in 27 patients (18 females and 9 males, mean aged at surgery 59.1-year old) whom a PLFE with patella thickness resection using developed minimally invasive method was performed. Data of preoperative and postoperative questionnaires, physical examinations, and radiographs were analyzed. The minimum follow-up was 12 months (mean, 24.1 months; range, 12-36 months). RESULTS The subjective outcomes included the anterior pain relief assessed by scores using the Western Ontario and McMaster Universities Arthritis Index score (scores improved considerably by 2.34 points with respect to pain and by 1.63 points with respect to function), visual analog scale, and Knee Society Score (that improved in 78% of the knees). The majority of these patients experienced improvement in their PF symptoms. The PF index decreased considerably after surgery. The mean patellar width and thickness were decreased after surgery, maintaining a width/thickness ratio of 1.8:1.0 after surgery. CONCLUSION PLFE with patella thickness resection aiming to decrease the high pressure in the lateral facet and improving congruence of the patella confirmed frequent pain relief. This surgical procedure is minimally invasive, relatively simple, and effective in selected patients and can be a valid early alternative to more complex operations. Level of Evidence: Level IV Therapeutic study.

The prognostic value of pain catastrophizing in health-related quality of life judgments after Total knee arthroplasty. Health Qual Life Outcomes 2018; 16:126. [PMID: 29914521 PMCID: PMC6006578 DOI: 10.1186/s12955-018-0955-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2017] [Accepted: 06/11/2018] [Indexed: 11/15/2022] Open
Abstract
Background Total knee arthroplasty (TKA) is a highly effective procedure that yields reductions in pain and disability associated with end stage osteoarthritis (OA) of the knee. Quality of life instruments are frequently used to gauge the outcomes of total knee arthroplasty (TKA). However, research suggests that post-TKA reductions in symptom severity may not be the sole predictors of quality of life post-TKA. The primary objective of the present study was to examine the prognostic value of catastrophic thinking in health-related quality of life (HRQoL) judgments in patients with severe OA after TKA. Methods In this study we used a prospective cohort design to examine the value of pain catastrophizing in predicting HRQoL 1 year after TKA. Participants with advanced OA of the knee who were scheduled for TKA were recruited at one of three hospitals in Canada. The study sample consisted of 116 individuals (71 women, 45 men) who completed study questionnaires at their pre-surgical evaluation and 1 year after surgery. Hierarchical regression analysis was used to assess the unique contribution of pre-surgical pain catastrophizing to the prediction of post-surgical HRQoL judgments. Results The results of the hierarchical regression equation revealed that the overall model was significant, F (9,106) = 8.3, p < 001, and accounted for 36.4% of the variance in the prediction of post-surgical physical component score of HRQoL. Pain catastrophizing was entered in the last step of the equation and contributed significant unique variance (β = −.35, p < .001) to the prediction of post-surgical physical component score of HRQoL above and beyond the variance accounted for by demographic variables, co-morbid health conditions, baseline HRQoL, and post-surgical reductions in pain, joint stiffness and physical disability. Conclusions The current findings highlight the importance of pre-surgical catastrophic cognitions in influencing HRQoL judgments after TKA. The findings suggest that psychosocial interventions designed to reduce pain catastrophizing before TKA might contribute to better quality of life outcomes following surgery.

Abstract
While OA is predominantly diagnosed on the basis of clinical criteria, imaging may aid with differential diagnosis in clinically suspected cases. While plain radiographs are traditionally the first choice of imaging modality, MRI and US also have a valuable role in assessing multiple pathologic features of OA, although each has particular advantages and disadvantages. Although modern imaging modalities provide the capability to detect a wide range of osseous and soft tissue (cartilage, menisci, ligaments, synovitis, effusion) OA-related structural damage, this extra information has not yet favourably influenced the clinical decision-making and management process. Imaging is recommended if there are unexpected rapid changes in clinical outcomes to determine whether it relates to disease severity or an additional diagnosis. On developing specific treatments, imaging serves as a sensitive tool to measure treatment response. This narrative review aims to describe the role of imaging modalities to aid in OA diagnosis, disease progression and management. It also provides insight into the use of these modalities in finding targeted treatment strategies in clinical research.

Abstract
Objectives To estimate the multi-dimensional health impact of radiographic knee OA and quantify the overall health-related quality of life (HRQoL) burden, using a preference-based health utilities measure. Methods Data on self-reported HRQoL, measured using the SF-12 multi-dimensional health state instrument, were obtained for 2895 patients with radiographic knee OA (Kellgren-Lawrence grade of at least 2) from the Osteoarthritis Initiative and for a general population sample of 3202 from the National Health Measurement Study. The SF-12 was converted to the six-dimensional SF-6D classification to compute preference-based health utilities. Generalized ordinal regression and multinomial regression were used to estimate the health loss on each SF-6D dimension for Osteoarthritis Initiative participants with radiographic knee OA relative to the general population, adjusted for differences in age, BMI, sex, ethnicity and educational level. Predicted SF-6D profiles were then used to compute the average HRQoL loss attributable to radiographic knee OA. Results Radiographic knee OA was associated with substantial health losses on all dimensions of the SF-6D except for social functioning. Health losses increased with the radiographic severity of OA in dimensions related to physical health, while there was no relationship between worse radiographic disease and worse self-assessed health in mental and emotional dimensions of health. Overall, radiographic knee OA was associated with a HRQoL detriment of 0.040-0.044 at Kellgren-Lawrence grade 2, increasing to 0.045-0.050 at grade 3 and 0.073-0.081 at grade 4. Conclusion Radiographic knee OA is significantly associated with worse HRQoL across most dimensions of health.

Abstract
AIMS The objective of this study is to characterize, based on clinical, radiographic, health-related, quality-of-life-related, and demographic variables, the profile of a large, homogeneous, cohort of patients undergoing knee or hip arthroplasty, in a public hospital. Current regulatory guidelines for structure-modifying agent are not clear regarding hard clinical endpoint. The "need for surgery" has been suggested as a potential relevant outcome, but, until now, it is poorly defined. By characterizing a large number of patients who undergo total hip or total knee replacement, this paper aims at providing a contribution to the better definition of the "need for surgery" in advanced OA of the lower limbs. METHODS Consecutive patients who underwent primary knee arthroplasty (KA) or hip arthroplasty (HA) between December 2008 and February 2013, in an academic hospital, and who were diagnosed with hip or knee osteoarthritis (OA) (ACR criteria). Data collected at baseline included demographic and clinical data; Kellgren-Lawrence radiological grading; Western Ontario and Mc Master Universities Arthritis Index (WOMAC); EuroQol five dimensions questionnaire and EuroQol visual analog scale; and 36-item Short Form Health Survey. RESULTS 626 subjects were included, 346 with hip OA and 280 with knee OA. Significant differences between subjects in need of an HA or of a KA were seen in terms of age (66.5 years versus 65 for hip), duration of complaints (2188 days versus 1146.5 for hip), BMI (28.68 kg/m² versus 27.07), radiological status (severe OA were found in 79.85% in knee group and 68.73% in hip group), comorbidities (FCI higher in knee group), traumatic of surgical history (37 versus 6%), and health-related quality of life and function (patients with HA had a poorer clinical status regarding WOMAC and WOMAC subscale). CONCLUSION Significant differences were observed between patients undergoing KA or HA. These differences might be useful to better understand the "need for surgery" status in these indications. This concept may help to define responders and failures to pharmacological treatment of OA.

Abstract
BACKGROUND Significant correlation has been previously demonstrated between radiographic and clinical diagnoses of knee osteoarthritis (OA); however, the specific findings on clinical examination that relate best to a radiographic diagnosis have not been fully elicited. AIMS We aimed to explore the relationship between clinical symptoms and physical findings with radiographic diagnoses of tibiofemoral and patellofemoral OA. METHODS This study was based on 409 individuals from the Hertfordshire Cohort Study, born between 1931 and 1939. Antero-posterior and lateral radiographs were taken of both knees. The presence of tibiofemoral and patellofemoral OA was defined according to the Kellgren and Lawrence score. Clinical symptoms, assessed using WOMAC, and physical findings were ascertained by examination. Relationships were assessed using multilevel univariate logistic regression. RESULTS In the 775 knees studied, the prevalence of physical findings was crepitus (25%), tibiofemoral tenderness (15%), bony swelling (12%), and pain on flexion (10%). Thirty-one percent (n = 238) knees demonstrated tibiofemoral OA, 28% (n = 220) showed patellofemoral OA, and 16% demonstrated OA in both locations. A global clinical symptom score was associated with increased risk of tibiofemoral OA (OR 12.5, 95% CI 5.4-29.0) and patellofemoral OA (OR 5.1, 95% CI 2.3-13.1). On clinical examination, the presence of crepitus, tibiofemoral tenderness, bony swelling, and pain on flexion was associated with increased risk of tibiofemoral OA; however, only tenderness was found to be associated with patellofemoral OA. CONCLUSION Global clinical symptom score was associated with radiographic tibiofemoral and patellofemoral OA. However, individual clinical signs were more strongly associated with tibiofemoral than patellofemoral OA.

Abstract
Abstract
Introduction: The objective of this paper is to analyse the correlation between pain and the degree of disability, and the lesions shown on radiological examination of KOA.
Material and method: The study encompassed 31 female patients (42 knees) aged 51-70 years, with diagnosed idiopathic knee osteoarthritis. Medical history and analysis of previously performed x-ray scans were conducted. The history included questions regarding pain (VAS, WOMAC index) and the maximum marching distance, the presence of oedema and instability as well as disability in everyday life (WOMAC index). The radiological lesions were assessed using the Kellgren and Lawrence Grading Scale. Moreover, the widths of the joint spaces were measured.
Results: The patients’ pain in everyday activities (WOMAC) showed a positive correlation with the presence of osteophytes (r=0.32), and the intensity of the pain on the VAS correlated with the presence of joint osteophytes (r=0.46) and with the elevation of the intercondylar eminence (r=0.32). The other disorders on the x-ray image did not correlate with the pain. Positive correlations were identified between the presence of oedema (r=0.57) and instability (r=0.39), and the presence of lesions in the patellofemoral joint. The patients’ disability in everyday activities (WOMAC) showed a negative correlation with the width of the joint spaces (r<-0.34). However, no correlations were observed between the remaining x-ray lesions and the WOMAC index.
Conclusions: Only a small number of subjects showed a correlation indicating an interdependency between the painful sensations and the degree of disability versus the progression of radiographic lesions. Among the KOA risk factors, it is worth noting the presence of obesity which, in these studies, affected more than half of the female patients.

Abstract
CONTEXT Assessment of health-related quality of life (HRQOL) after injury is important. Differences in HRQOL between nonathletes and athletes and between injured and uninjured athletes have been demonstrated; however, the evidence has not been synthesized. OBJECTIVE To answer the following questions: (1) Does HRQOL differ among adolescent and collegiate athletes and nonathletes? (2) Does HRQOL differ between injured adolescent and collegiate athletes or between athletes with a history of injury and uninjured athletes or those without a history of injury? DATA SOURCES We systematically searched CINAHL, MEDLINE, SPORTDiscus, and PubMed. A hand search of references was also conducted. STUDY SELECTION Studies were included if they used generic instruments to compare HRQOL outcomes between athletes and nonathletes and between uninjured and injured athletes. Studies were excluded if they did not use a generic instrument, pertained to instrument development, or included retired athletes or athletes with a chronic disease. DATA EXTRACTION We assessed study quality using the modified Downs and Black Index Tool. Bias-corrected Hedges g effect sizes and 95% confidence intervals (CIs) were calculated. The Strength of Recommendation Taxonomy (SORT) was used to determine the overall strength of the recommendation. A random-effects meta-analysis was performed for all studies using the composite or total score. DATA SYNTHESIS Eight studies with modified Downs and Black scores ranging from 70.6% to 88.4% were included. For question 1, the overall random-effects meta-analysis was weak (effect size = 0.27, 95% confidence interval = 0.14, 0.40; P < .001). For question 2, the overall random-effects meta-analysis was moderate (effect size = 0.68, 95% confidence interval = 0.42, 0.95; P < .001). CONCLUSIONS Grade A evidence indicates that athletes reported better HRQOL than nonathletes and that uninjured athletes reported better HRQOL than injured athletes. However, the overall effect for question 1 was weak, suggesting that the differences between athletes and nonathletes may not be clinically meaningful. Clinicians should monitor HRQOL after injury to ensure that all dimensions of health are appropriately treated.

Abstract
Osteoarthritis is a syndrome affecting a variety of patient profiles. A European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis and the European Union Geriatric Medicine Society working meeting explored the possibility of identifying different patient profiles in osteoarthritis. The risk factors for the development of osteoarthritis include systemic factors (e.g., age, sex, obesity, genetics, race, and bone density) and local biomechanical factors (e.g., obesity, sport, joint injury, and muscle weakness); most also predict disease progression, particularly joint injury, malalignment, and synovitis/effusion. The characterization of patient profiles should help to better orientate research, facilitate trial design, and define which patients are the most likely to benefit from treatment. There are a number of profile candidates. Generalized, polyarticular osteoarthritis and local, monoarticular osteoarthritis appear to be two different profiles; the former is a feature of osteoarthritis co-morbid with inflammation or the metabolic syndrome, while the latter is more typical of post-trauma osteoarthritis, especially in cases with severe malalignment. Other biomechanical factors may also define profiles, such as joint malalignment, loss of meniscal function, and ligament injury. Early- and late-stage osteoarthritis appear as separate profiles, notably in terms of treatment response. Finally, there is evidence that there are two separate profiles related to lesions in the subchondral bone, which may determine benefit from bone-active treatments. Decisions on appropriate therapy should be made considering clinical presentation, underlying pathophysiology, and stage of disease. Identification of patient profiles may lead to more personalized healthcare, with more targeted treatment for osteoarthritis.

Abstract
Knee osteoarthritis (OA) is a degenerative joint condition and a leading cause of physical disability in the United States. Quadriceps weakness and inflammatory cytokines contribute to the pathogenesis of knee OA, and both of which, increase with vitamin D deficiency. Other micronutrients, such as vitamins C and E and β-carotene, modulate inflammatory cytokines and decrease during inflammation. The purpose of this study was to test the hypothesis that vitamin D deficiency associates with quadriceps weakness, an increase in serum cytokines, and a decrease in circulating micronutrients in subjects with knee OA. Subjects (age, 48±1 y; serum 25(OH)D, 25.8±1.1 ng/mL) with knee OA were categorized as vitamin D deficient (n=17; serum 25(OH)D≤20 ng/mL), insufficient (n=21; serum 25(OH)D 20–29 ng/mL), or sufficient (n=18; serum 25(OH)D≥30 ng/mL). Single-leg strength (concentric knee extension–flexion contraction cycles at 60 °/s) and blood cytokine, carotene (α and β), ascorbic acid, and tocopherol (α and γ) concentrations were measured. Quadriceps peak torque, average power, total work, and deceleration were significantly (all p<0.05) impaired with vitamin D deficiency. Serum γ-tocopherol concentrations were significantly (p<0.05) increased with vitamin D deficiency. In the vitamin D sufficient group, γ-tocopherol inversely correlated (r=−0.47, p<0.05) with TNF-α, suggesting a pro-inflammatory increase with a γ-tocopherol decrease despite a sufficient serum 25(OH)D concentration. We conclude that vitamin D deficiency is detrimental to quadriceps function, and in subjects with vitamin D sufficiency, γ-tocopherol could have an important anti-inflammatory role in a pathophysiological condition mediated by inflammation. We investigated the vitamin D association with mediators of knee osteoarthritis. Vitamin D deficiency associated with quadriceps dysfunction. Vitamin D deficiency was not associated with serum cytokines. Vitamin D deficiency associated with increased plasma γ-tocopherol concentrations. γ-Tocopherol inversely correlated with TNF-α in vitamin D sufficient subjects.

Abstract
In this study, we aimed to explore the relationship between radiological findings and functional status in patients with knee osteoarthritis (OA). In this study, 117 female patients diagnosed with knee osteoarthritis according to the ACR criteria were included. Antero-posterior knee radiographs of the patients were graded according to Kellgren-Lawrence, and functional capacity was evaluated with WOMAC and Lequesne indexes. Quadriceps and hamstring muscle strengths were also concentrically measured using an isokinetic dynamometer, five repetitions at 90°/s and 20 repetitions at 180°/s. In this study, a significant relationship was determined between the age, weight, praying period, and pain period of the patients with the radiological findings. No significant relationship was determined between the functional capacity of knee and muscle strength and the radiological findings. However, left hamstring functioning capacity was found as lower in the group with the radiological findings. The radiological findings in knee OA are not associated with decrease in knee muscle strength and functional capacity. Clinical symptoms such as pain, decrease in range of motion, etc. in knee OA may be responsible for decrease in knee muscle strength and functional capacity.

Abstract
BACKGROUND AND AIMS Osteoarthritis (OA) of the knee or hip is associated with limitations in activities of daily life. There are only a few long-term studies on how knee or hip OA affects the course of physical performance. The aim of this study was to investigate the effects of knee or hip OA on physical performance during a follow-up period of 10 years. METHODS Participants in the Longitudinal Aging Study Amsterdam with self-reported hip or knee OA (N = 155) were prospectively followed for 10 years on 4 occasions from the onset of OA and compared to participants without OA (N = 1004). Physical performance was tested with walk, chair stand and balance tests. Scores for each test were summed to a total performance score (range 0-12), higher scores indicating better performance. Generalized estimating equations were used to analyze differences between participants with and without OA, unadjusted as well as adjusted for confounders. RESULTS There was a significant interaction between OA and sex (P = 0.068). Both in men and women, total performance was lower for participants with OA, with greater differences in men. Chair stand and walking performance (P < 0.05), but not balance, were lower in participants with OA. After adjustment for confounders, these associations remained significant in men but not in women. Additional analyses correcting for follow-up duration and attrition showed lower performance scores for men and women with OA. CONCLUSIONS OA negatively affected physical performance 3-6 years after it was first reported. Performance in men with OA was more affected than in women.

Abstract
OBJECTIVE To determine whether the method of disease severity measurement influences the magnitude of knee extensor force deficits in knee osteoarthritis (OA). METHODS Data from the Osteoarthritis Initiative (n = 659) were analyzed. Knee extensor force was assessed with isometric contractions. Clinical severity was measured with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Patients were stratified into tertiles of severity (i.e., moderate, mild, and severe OA) based on the lowest, middle, and highest WOMAC scores, respectively. Kellgren/Lawrence (K/L) grading was used to assess radiographic severity of the tibiofemoral compartment and patients were again stratified into mild (K/L grade <2), moderate (K/L grade 2), and severe (K/L grade >2) knee OA. RESULTS When stratifying with the WOMAC, force was significantly lower in the severe group compared to the mild (~18% lower; P < 0.001) and moderate groups (~9% lower; P = 0.03), and in the moderate group compared to the mild group (∼10% lower; P = 0.03). When stratifying with K/L grade, small nonsignificant differences were observed in the severe (~7% lower; P = 0.19) and moderate groups (~8% lower; P = 0.08) compared to the mild group. Large intragroup variability was observed when comparing WOMAC scores across radiographic severity (coefficients of variation were 79.3%, 74.6%, and 61.6% for K/L grade <2, K/L grade 2, and K/L grade >2, respectively). CONCLUSION The method of disease severity stratification influences the magnitude of knee extensor force deficits because no difference in force between disease subgroups was observed when stratifying with K/L grade. Furthermore, there was large variability in the WOMAC score within each radiographic subgroup, highlighting the limitations in using radiographic measures to reflect symptom severity.

Abstract
Over the last 20 years, several studies have investigated the ability of glucosamine sulfate to improve the symptoms (pain and function) and to delay the structural progression of osteoarthritis. There is now a large, convergent body of evidence that glucosamine sulfate, given at a daily oral dose of 1,500 mg, is able to significantly reduce the symptoms of osteoarthritis in the lower limbs. This dose of glucosamine sulfate has also been shown, in two independent studies, to prevent the joint space narrowing observed at the femorotibial compartment in patients with mild-to-moderate knee osteoarthritis. This effect also translated into a 50 % reduction in the incidence of osteoarthritis-related surgery of the lower limbs during a 5-year period following the withdrawal of the treatment. Some discrepancies have been described between the results of studies performed with a patent-protected formulation of glucosamine sulfate distributed as a drug and those having used glucosamine preparations purchased from global suppliers, packaged, and sold over-the-counter as nutritional supplements.

Abstract
OBJECTIVE There is ongoing debate on whether an association between radiographic and clinical osteoarthritis (OA) exists. We hypothesized that the inconsistency in the detection of an association might be caused by different definitions of OA, by different radiographic protocols, and by scoring methods for radiographic damage and symptoms. The goal of this study was to evaluate which methodological criteria are important to detect an association between radiographic and clinical OA of hip and knee. METHODS A literature search was performed with the keywords 'OA', 'hip', 'knee', 'radiographic', and 'clinical' and results were screened for relevant studies. Quality criteria for study characteristics and methodology were developed. Studies were classified according to these criteria and the presence of an association between radiographic and clinical OA was scored. The importance of methodological quality and patient characteristics on the presence of an association was evaluated. RESULTS The literature search resulted in 39 studies describing an association between radiographic and clinical OA. The frequency of an association between radiographic and clinical OA outcome measures diminished when less quality criteria were fulfilled. Specifically the criterion for standardized outcome measures appeared important in the detection of an association. The association was not influenced by patient characteristics. Only four studies were identified that fulfilled all quality criteria and in these studies an association was found for the knee joint and an inconsistent association was found for the hip joint. CONCLUSION Methodological quality criteria are of importance to reveal an association between radiographic and clinical OA.

Abstract
OBJECTIVE Development of functional limitation is thought to be unrelated to changes in severity of radiographic osteoarthritis (OA) of the knee. We evaluated the relationship of change in radiographic OA to the incidence of severe functional limitation. METHODS Participants of the Multicenter Osteoarthritis Study, a cohort study of persons with or at high risk of knee OA, were evaluated at 0 and 30 months. Subjects were classified as having no, incident, stable, or worsening radiographic OA. Incidence of severe functional limitation was defined by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical function scores (≥36.1/68) and walking speed (≤1.0 meter/second) at 30 months. The relationship of the change in radiographic OA to the incidence of severe functional limitation was evaluated by calculating risk ratios adjusted for potential confounders. RESULTS Of the 2,210 subjects included (mean age 62 years, mean body mass index 30 kg/m², 60% women), 53% had no, 6% had incident, 14% had stable, and 27% had worsening radiographic OA. Persons with incident radiographic OA had 1.9 and 1.8 times the risk by WOMAC physical function score and walking speed, respectively, to have incident severe functional limitation compared with those with no radiographic OA over 30 months. Compared with those with stable radiographic OA, persons with worsening radiographic OA had 2.2 and 2.3 times the risk of incident severe functional limitation, respectively. CONCLUSION Changes in structural disease are associated with the development of severe functional limitations in persons with or even at high risk of knee OA.

Abstract
BACKGROUND The effects of gender on the relationship between symptom manifestations and radiographic grades of knee osteoarthritis are not well understood. QUESTIONS/PURPOSES We therefore determined the increments of symptom progression with regard to radiographic grades of knee osteoarthritis and asked if those increments differed by gender and whether symptom severity was differentially manifested by gender within the same grade. METHODS We recruited 660 community residents; 368 (56%) women and 292 (44%) men. The mean subject age was 71.5 years (range, 65-91 years). Severity of symptoms was measured using the WOMAC and SF-36 scales, and the radiographic severity using Kellgren-Lawrence grades. Incremental changes in WOMAC and SF-36 scores were compared between adjacent Kellgren-Lawrence grades separately in men and women, and in the overall population. We compared symptom severity between men and women with the same radiographic grade. RESULTS For the entire cohort, the mean incremental change in symptom severity was not gradual between the adjacent radiographic grades but was greater between Kellgren-Lawrence Grades 1 and 2 and Grades 2 and 3 than between Grades 0 and 1 or Grades 3 and 4. The patterns of incremental changes in symptom severity differed between men and women: women had more severe symptom progression between Kellgren-Lawrence Grades 2 and 3 and Grades 3 and 4 than men. Furthermore, women had worse mean WOMAC and SF-36 scores than men with the same radiographic grade of knee osteoarthritis. CONCLUSIONS These data suggest symptom progression is not gradual between adjacent radiographic grades, and for the same radiographic grade, symptoms are worse in women. LEVEL OF EVIDENCE Level III, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.

Abstract
To be able to prevent progression of osteoarthritis, the knowledge of prognostic factors of this progression is important. If certain prognostic factors are modifiable, they may enhance our ability to reduce osteoarthritis progression. Even if these prognostic factors are not modifiable, they can still be used to identify high-risk groups, which may have implications for patient information and the perspective of medical treatment. Prognostic factors of progression are reviewed here, mainly for hip and knee osteoarthritis as most data available concern these localisations. Areas of further research are highlighted.

Abstract
CONTEXT Health-related quality of life (HRQOL) is a global concept that takes into account the physical, psychological, and social domains of health. Determining the extent to which injury affects HRQOL is an important aspect of rehabilitation practice, enabling comparisons of clinical outcomes across different conditions in diverse patient groups. OBJECTIVE To examine the extent to which a self-reported recent injury affected HRQOL in adolescent athletes using 2 generic patient self-report scales. DESIGN Cross-sectional study. SETTING High school classrooms and athletic training facilities. PATIENTS OR OTHER PARTICIPANTS A convenience sample of uninjured (n = 160) and injured (n = 45) adolescent athletes. INTERVENTION(S) THE INDEPENDENT VARIABLE WAS INJURY STATUS: uninjured versus injured. All participants completed a self-administered brief health status questionnaire and the Short Form-36 Health Survey Questionnaire (SF-36) and Pediatric Outcomes Data Collection Instrument (PODCI) in a counterbalanced manner. MAIN OUTCOME MEASURE(S) Dependent variables included 8 subscale and 2 composite scores of the SF-36 and 5 subscale scores and 1 global score of the PODCI. Group differences were assessed with the Mann-Whitney U test (P < or = .05) and reported as median and interquartile range. RESULTS On the SF-36, the injured group demonstrated lower scores (P < .008) for physical functioning, limitations due to physical health problems, bodily pain, social functioning, and the physical composite. On the PODCI, the injured group reported lower scores (P < .01) on the pain and comfort subscale and the global score. CONCLUSIONS Adolescent athletes with self-reported injuries demonstrated lower HRQOL than their uninjured peers. As expected, recent injury affected physical functioning and pain. Social functioning (on the SF-36) and global HRQOL (on the PODCI) also decreased, suggesting that injuries affected areas beyond the expected physical component of health. Clinicians need to recognize the full spectrum of negative influences that injuries may have on HRQOL in adolescent athletes.

Abstract
The promise of evidence-based medicine is to integrate the highest levels of clinical data with patient outcomes. After framing the question and identifying appropriate studies, evaluating their relevance to clinical practice is highly dependent on the instruments and measures selected to demonstrate outcomes. Currently, there are hundreds of outcomes measures available in the orthopedic literature evaluating these treatments, and it is not uncommon for different measures to produce conflicting results. Consequently, the ability to evaluate an outcomes measure is critical in determining the value of a specific treatment intervention. Similarly, selecting the appropriate outcomes measure for research or clinical purposes is an important decision that may have far reaching implications on reimbursement, surgeon reputation, and patient treatment success. Evidence-based orthopedic surgery is indeed possible, but demands a detailed understanding of why appropriate outcomes selection is important, the difference between clinician-based and patient-reported outcomes (PROs), and potential future directions in orthopedics outcomes research.

Abstract
We studied whether contact stress estimates from knee magnetic resonance images (MRI) predict the development of incident symptomatic tibiofemoral osteoarthritis (OA) 15 months later in an at-risk cohort. This nested case-control study was conducted within a cohort of 3,026 adults, age 50 to 79 years. Thirty cases with incident symptomatic tibiofemoral OA by their 15 month follow-up visit were randomly selected and matched with 30 control subjects. Symptomatic tibiofemoral OA was defined as daily knee pain/stiffness and Kellgren-Lawrence Grade > or =2 on weight bearing, fixed-flexion radiographs. Tibiofemoral geometry was segmented on baseline knee MRI, and contact stresses were estimated using discrete element analysis. Linear mixed models for repeated measures were used to examine the association between articular contact stress and case/control status. No significant intergroup differences were found for age, sex, BMI, weight, height, or limb alignment. However, the maximum articular contact stress was 0.54 +/- 0.77 MPa (mean +/- SD) higher in incident OA cases compared to that in control knees (p = 0.0007). The interaction between case-control status and contact stress was significant above 3.20 MPa (p < 0.0001). The presence of differences in estimated contact stress 15 months prior to incidence suggests a biomechanical mechanism for symptomatic tibiofemoral OA and supports the ability to identify risk by subject-specific biomechanical modeling.

Abstract
Pain during osteoarthritis (OA) of the knee does not necessarily correlate with the severity of the radiographic grade, and the mechanism of pain has not been completely clarified. The purpose of this study was to evaluate risk factors for pain in the knee OA using epidemiologic analyses. We evaluated 518 out of 4183 people over the age of 40 (156 males and 362 females) from Shinyoshitomi village, Japan. Mean ages were 63.8 years for men and 60.7 years for women. Screening included a physical examination of the knee and a standing AP roentgenogram of the bilateral knee. Radiographic OA was defined as a Kellgren-Lawrence grade 2 or higher. All data were coded and pain risk factors were evaluated using a multiple logistic regression model. Radiographic OA was observed in 18.4% of men and 26% of women. Of these subjects with OA, 10.9% of men and 32.5% of women complained of knee pain. Seven factors-age, gender, BMI, radiographic grade, varus-valgus laxity, torque of quadriceps muscles, and varus-valgus alignment-were evaluated as potential risk factors for pain. A significant increase in the odds ratio was observed with varus-valgus laxity (p=0.005; odds ratio, 3.04). Our results suggest that varus-valgus laxity is a risk factor for pain during knee OA.

Abstract
OBJECTIVES The first objective was to assess the effect of the chondroitin 4 and 6 sulphate (CS) on health-related quality of life using utility values in patients with knee osteoarthritis (OA) during a 24-month treatment course. The second objective was, using these data, to conduct economic analyses. METHODS Data from the STOPP study was used. This study was a randomised, double-blind, placebo (PL) -controlled trial of 2-year duration. In the STOPP study, authors assessed quality of life using the Western Ontario and McMaster Osteoarthritis Index (WOMAC). WOMAC scores were translated into Health Utility Index (HUI) scores using a specific formula. Incremental cost effectiveness ratio (ICER) was calculated taking into account the cost of CS and its effect on HUI scores, compared to PL. RESULTS At baseline, the mean (SD) HUI scores were 0.59 (0.17), and 0.59 (0.18) for the PL and CS groups, respectively (p=0.31 between the two groups). The mean (SD) HUI scores changes from baseline to 6 months were 0.02 (0.02), and 0.05 (0.01) for the PL and CS groups, respectively (p=0.03). After 24 months of follow-up, HUI score increases by 0.04 (0.02) in the PL group and by 0.05 (0.02) in the CS group (p=0.37). Using the price bracket of CS in Europe, ICER assessment always resulted in a cost below €30,000 per QALY gained, after 6, 12 and 24 months of treatment. CONCLUSION CS treatment increases health utilities in patients with knee OA compared to PL over the first 6 months of treatment. Economic evaluation based on these data suggests that CS treatment could be considered as cost-effective in patients with knee OA up to a period of 24 months. A limitation in this study is the absence of direct utility assessment as well as the absence of effective treatment as comparator.

Abstract
Background Studies have suggested that the symptoms of knee osteoarthritis (OA) are rather weakly associated with radiographic findings and vice versa. Our objectives were to identify estimates of the prevalence of radiographic knee OA in adults with knee pain and of knee pain in adults with radiographic knee OA, and determine if the definitions of x ray osteoarthritis and symptoms, and variation in demographic factors influence these estimates. Methods A systematic literature search identifying population studies which combined x rays, diagnosis, clinical signs and symptoms in knee OA. Estimates of the prevalence of radiographic OA in people with knee pain were determined and vice versa. In addition the effects of influencing factors were scrutinised. Results The proportion of those with knee pain found to have radiographic osteoarthritis ranged from 15–76%, and in those with radiographic knee OA the proportion with pain ranged from 15% – 81%. Considerable variation occurred with x ray view, pain definition, OA grading and demographic factors Conclusion Knee pain is an imprecise marker of radiographic knee osteoarthritis but this depends on the extent of radiographic views used. Radiographic knee osteoarthritis is likewise an imprecise guide to the likelihood that knee pain or disability will be present. Both associations are affected by the definition of pain used and the nature of the study group. The results of knee x rays should not be used in isolation when assessing individual patients with knee pain.

Abstract
UNLABELLED Isolated patellofemoral osteoarthritis in the healthy middle-aged population is a challenging problem. Fifty-one knees in 50 patients with isolated patellofemoral osteoarthritis were treated by partial lateral facetectomy, lateral release, and medialization of the tibial tubercle. The minimum followup was 7 months (mean, 20.2 months; range, 7-32 months). Preoperative radiographs showed Ahlbäck Grades III and IV lateral patellofemoral joint space narrowing. The mean age of the patients was 60.1 years (range, 46-81 years). The subjective outcome was based on the WOMAC and the McCarroll score. Posteroanterior flexion weightbearing views, lateral views, and 45 degrees axial views were taken. According to the WOMAC score, the scores improved considerably by 2.34 points with respect to pain and by 1.63 points with respect to function. The Insall-Salvati index decreased considerably but still remained in the physiologic range. The majority of these patients experienced improvement in their patellofemoral symptoms. However, the clinical outcome was not better in comparison to other surgical procedures. After the short followup, we would not recommend combined lateral facetectomy, lateral release, and medialization of the tibial tubercle until longer results are available. LEVEL OF EVIDENCE Level IV Therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Abstract
INTRODUCTION Anterior cruciate ligament reconstruction is an increasingly established method even in patients over 40 years old. Recent studies with regard to this procedure used BTB transplants. We did a retrospective follow-up examination on over-40-year-old patients with anterior cruciate ligament reconstruction using hamstring transplants and compared them to a younger control group. Our hypothesis is that functional outcome after ACL-reconstruction is comparable in patients under and over 40 years of age. MATERIALS AND METHODS Retrospective follow-up examinations in 28 patients, 11 women and 17 men. The average age at the time of operation was 43.5 years (range 40-61). The average follow-up period was 30.4 months. Half of the patients had a femoral fixation in TransFix technique (Arthrex, Naples, USA), while the other 14 patients had a femoral bioscrew fixation (Arthrex, Naples, USA). Objectivity was ensured by measurements of anterior tibial translation with the rolimeter (Aircast). The functional outcome was determined by clinical scores (Tegner activity scale, Lysholm knee score, OAK score and IKDC score). The degree of arthrosis was defined on the basis of tunnelview radiographs and compared to the non-operated site. Functional results and degree of laxity was compared to a sex matched control group (mean age 28.0). RESULTS The median values for the Lysholm knee score were 91.5 points (range 69-100), for the OAK score 93.5 points (range 67-100) and for the IKDC score 83.35 points (range 62.1-100). For the Tegner activity scale values of 4.5 points (range 3-8) were obtained. In the IKDC knee examination form we found normal and nearly normal values in 86% and in the OAK examination score good and very good results in 82%. Ninety-three percent had an AP side-to-side difference of <5 mm in the operated knee. Subjectively, 75% reported that they had no feeling of instability, even when practising sport. No significant correlation between functional outcome and patients' age was present. Furthermore there were no significant differences between the investigated and the younger control group. The most advanced signs of arthrosis were found in the medial compartment of the operated side (degree A: 36%; degree B: 46%; degree C: 14%; degree D: 4%). CONCLUSION The predominantly good results and a high level of patient satisfaction show that anterior cruciate ligament reconstruction is justified even in over-40-year-old patients with persistend subjective symptomatic anterior knee instability. The indication for reconstruction should be based on individual factors such as level of activity or subjective feeling of instability rather than on a dogmatic age limit. Advanced arthrotic changes compared to the healthy side, might be due to a too long period of preoperative decision making.

Abstract
Joint morbidity in haemophilia has traditionally been measured using clinical and radiological scores. There have been no reliable, validated tools for the assessment of functional independence in persons with haemophilia till recently. The Functional Independence Score in Haemophilia (FISH) has been developed as a performance based assessment tool to address this need. The FISH is designed to measure the patient's independence in performing activities of daily living (grooming and eating, bathing and dressing), transfers (chair and floor), and mobility (walking, step climbing and running). On assessment of its psychometric properties in 63 patients with haemophilia (mean age 14 years), FISH was found to have good internal consistency (Cronbach's alpha of 0.85). It had moderate correlation with the World Federation of Hemophilia clinical score (r = -0.61), and a correlation with the Pettersson score of -0.38. It had good correlation with other self-rated functional scores, such as the Stanford Health Assessment Questionnaire (r = -0.75); the Western Ontario and McMaster Universities Osteoarthritis Index (r = -0.66) and the Haemophilia Activities List (HAL) (r = -0.66). It had good reliability with a pooled intra class correlation of 0.98. On assessing responsiveness following treatment of flexion deformities of the knee in 12 patients, the FISH showed significant changes in the score with a standardized responsiveness mean of -1.93. In conclusion, the FISH was found to be a reliable and valid tool with good internal consistency and responsiveness to therapy, for the assessment of functional independence in persons with haemophilia.

Abstract
Glucosamine is a natural amino sugar and a normal constituent of glycosaminoglycans in the cartilage matrix and synovial fluid of joints. Crystalline glucosamine sulfate salt has been approved as a medicinal product for the treatment of osteoarthritis in several European countries. Nevertheless, although it has been prescribed for more than 10 years, it is only due to the research in the last 5 years that the scientific basis underlying its beneficial effects are starting to be clarified. In randomised, double-blind, placebo-controlled trials, this compound clinically controls pain and produces beneficial effects in patients with knee osteoarthritis, possibly delaying the appearance of long-term structural changes in the joint (i.e., it has a structure-modifying effect). Furthermore, it has an excellent toxicity profile. Despite the different lines of investigation that have been followed, the mechanism of action of glucosamine sulfate still remains to be clearly defined. However, the activity of glucosamine sulfate has recently been related to its capacity to downregulate the catabolic effects of pro-inflammatory molecules, such as IL-1, which are present in osteoarthritic cartilage.

Abstract
OBJECTIVE To systematically review studies describing the course of functioning in patients with osteoarthritis (OA) of the hip or knee and identifying potential prognostic factors. METHODS A systematic search was performed. Studies involving patients with hip or knee OA, >6 months of followup, and outcome measures on functional status or pain were included. Methodologic quality was assessed using a standardized set of 11 criteria; a qualitative data analysis was performed. RESULTS Approximately 6,500 titles and abstracts were screened and 48 publications were considered for inclusion. Eighteen studies, 4 of which met the high methodologic quality criteria, were included. For hip OA, there was limited evidence that functional status and pain do not change during the first 3 years of followup. After 3 years, however, a worsening of functional status and pain was seen. For knee OA, there was conflicting evidence for the first 3 years and limited evidence for worsening of pain and functional status after 3 years. Furthermore, limited evidence was established for negative associations between future functional status and laxity, proprioceptive inaccuracy, age, body mass index, and knee pain intensity. In contrast, greater muscle strength, better mental health, better self-efficacy, social support, and more aerobic exercise were protective factors in the first 3 years. CONCLUSION Pain and functional status in hip or knee OA seem to deteriorate slowly, with limited evidence for worsening after 3 years of followup. In specific subgroups, prognosis in the first 3 years of followup was either worse or better, as both risk factors and protective factors were identified. Prognostic factors included biomechanical factors, psychological factors, clinical factors, and treatment modalities. To strengthen the evidence, further high-quality longitudinal research on hip or knee OA functioning is needed.

Abstract
Treatment of hemophilia aims to minimize structural damage to joints and maximize patients' functional independence and quality of life. From an orthopedic perspective, treatment efficacy can be judged by quantifying the extent of musculoskeletal damage. Joint scores--both clinical and radiologic--have traditionally been measured in patients with hemophilia. However, such scores may lack the sensitivity to detect early changes in the hemophilic joint, and this has prompted the development of more sensitive measures. In addition, scores based on the status of individual joints do not consider the impact of arthropathy on overall musculoskeletal function. It would prove valuable to understand the implications of small differences in clinical/radiologic scores in terms of overall musculoskeletal function and patients' quality of life. The development of functional scores such as the Functional Independence Score for Haemophilia (FISH) and the Haemophilia Activities List (HAL), along with the quality-of-life (QoL) measurement tools, have helped to provide a more comprehensive assessment of health in hemophilia. Such improved understanding should assist with the development of contextually relevant guidelines for the management of hemophilia.

Abstract
The experience of pain is characterized by tremendous inter-individual variability. Indeed, an identical noxious stimulus can produce vastly different pain responses across individuals. Historically, scientists have regarded this variability as a nuisance; however, substantial data suggest that these individual differences may provide valuable information that can be used to enhance clinical management of pain. This paper discusses several factors that contribute to individual differences in pain perception, including demographic (ie, sex, age, and ethnicity), genetic, and psychosocial variables. These factors are discussed in the context of the biopsychosocial model of pain, which posits that pain perception is influenced by interactions among biologic, psychosocial, and sociocultural factors. Finally, the clinical and scientific implications of individual differences in pain are discussed.

Abstract
BACKGROUND The purpose of this multi-center study was to examine the outcomes of importance for patients seeking treatment for foot and ankle disorders. An improved understanding of patient outcome preferences will assist surgeons in improving patient satisfaction. METHODS An open-ended priority function questionnaire was administered to 235 patients presenting as new patients to five different outpatient locations. The questionnaire was designed to identify activities of importance to patients and was based on the McMaster Toronto Arthritis (MACTAR) patient preference disability questionnaire. Subjects were asked to list the specific activities that were limited by their condition. Open-ended answers were written on five blank spaces and then ranked as to their importance. The visual analog pain scale was recorded as a measure of the severity of the patient's symptoms at the time the response was made. The outpatient settings were two university hospitals, two private offices with academic affiliation, and one private office. Two hundred thirty-five surveys were collected between September and November of 2000; 227 surveys were acceptable for analysis. The respondents included 132 females (58.1%), 94 males (41.4%) and one patient who did not specify his gender (0.4%). The mean age was 45.8 (range 18 to 83) years. RESULTS Average pain at the time of assessment was 2.7 on a scale of 0 to 9 and was reported to increase to 4.8 in a typical day. The most frequently ranked limitations were difficulty with walking (159), running (73), standing (55), and exercise (54). Walking also was the issue ranked as the highest priority (77 of 159), while running (11 of 73), standing (10 of 55) and exercise (3 of 54) were assigned lesser priority values. Only 68 of 227 respondents failed to list walking as an issue. Work, sleep, and social activities were not commonly cited as issues of importance. CONCLUSION Patients presenting to office practices identified as specializing in foot and ankle disorders are predominantly middle-aged women in mild to moderate pain. Walking is the function most frequently identified as a problem and ranked as the highest priority for improvement. Social limitations were unlikely to be named as a limitation in this population.

Abstract
OBJECTIVE To examine the association between radiographic classification of severe knee osteoarthritis and measurements of function, pain and power. DESIGN Cross-sectional study. SETTING Specialist orthopaedic hospital. SUBJECTS One hundred and twenty-three patients on the waiting list for elective knee arthroplasty. OUTCOME MEASURES Weight-bearing antero-posterior radiographs scored for severity of osteoarthritis using the Kellgren and Lawrence scale. Function measured using the function subscale of the WOMAC (Western Ontario and McMaster Universities) index, timed tests of walking speed and sit-to-stand. Pain measured using the pain subscale of the WOMAC index and a visual analogue scale. Extensor strength of the lower limb measured with the leg extensor power rig. RESULTS Within any radiographic grade there was considerable variation in function: WOMAC function for patients with grade 2 mean 64 (47-86), grade 3 mean 47 (12-89) grade 4 mean 45 (2-92). There was poor correlation between radiographic score function, pain or muscle power, with no statistically significant associations. A wide range of scores was also seen within patients with the same radiographic grade. CONCLUSIONS Radiographic score was not found to be closely associated with function. Amongst patients with the same radiographic score there was considerable variation in function, pain and power.

Abstract
OBJECTIVE To compare the measurement properties of the generic Health Assessment Questionnaire (HAQ) and the disease-specific Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). METHODS Physical function, pain, and radiographic progression were assessed in knee or hip osteoarthritis patients (n = 271) who had 2 radiographs that were at least 6 months apart from 6 ARAMIS (Arthritis, Rheumatism, and Aging Medical Information System) databanks. Data were compared at baseline and after a mean of 3.2 (SE 0.10) years. Correlation coefficients and standardized effect sizes (SES) were used to assess their relationship and responsiveness. RESULTS The majority of items in the 2 function and pain scales overlapped and were highly and significantly correlated with each other at baseline and last assessments (function at baseline rs = 0.71 and function at last assessment rs = 0.79, P < 0.0001; pain at baseline rs = 0.70 and pain at last assessment rs = 0.76, P < 0.0001). The HAQ disability index and total knee score were more sensitive to detection of disease progression than the WOMAC (SES for HAQ = 0.27; SES for WOMAC = -0.05). CONCLUSION Both instruments showed favorable measurement properties, with the HAQ having the advantages of being more sensitive to change and adaptable to a wide variety of diseases and conditions, which contribute to the generalizability of findings.

Abstract
UNLABELLED After successful cancer pain initiatives, efforts have been recently made to liberalize the use of opioids for the treatment of chronic nonmalignant pain. However, the goals for this treatment and its place among other available treatments are still unclear. Cancer pain treatment is aimed at patient comfort and is validated by objective disease severity. For chronic nonmalignant pain, however, comfort alone is not an adequate treatment goal, and pain is not usually proportional to objective disease severity. Therefore, confusion about treatment goals and doubts about the reality of nonmalignant pain entangle therapeutic efforts. We present a case history to demonstrate that this lack of proportionality fosters fears about malingering, exaggeration, and psychogenic pain among providers. Doubt concerning the reality of patients' unrelieved chronic nonmalignant pain has allowed concerns about addiction to dominate discussions of treatment. We propose alternate patient-centered principles to guide efforts to relieve chronic nonmalignant pain, including accept all patient pain reports as valid but negotiate treatment goals early in care, avoid harming patients, and incorporate chronic opioids as one part of the treatment plan if they improve the patient's overall health-related quality of life. Although an outright ban on opioid use in chronic nonmalignant pain is no longer ethically acceptable, ensuring that opioids provide overall benefit to patients requires significant time and skill. Patients with chronic nonmalignant pain should be assessed and treated for concurrent psychiatric disorders, but those with disorders are entitled to equivalent efforts at pain relief. The essential question is not whether chronic nonmalignant pain is real or proportional to objective disease severity, but how it should be managed so that the patient's overall quality of life is optimized. PERSPECTIVE The management of chronic nonmalignant pain is moving from specialty settings into primary care. Primary care providers need an ethical framework within which to adopt the principles of palliative care to this population.

Abstract
OBJECTIVES To capture changes in the quality of life (QoL) occurring in patients with osteoarthritis (OA) during treatment with non-specific non-steroidal anti-inflammatory drugs (NSAIDs) and to identify factors that predict such changes. METHODS A naturalistic, prospective follow up of 783 patients with OA in whom primary care physicians decided to start treatment with non-selective NSAIDs. Short Form-36 (SF-36) and the Western Ontario and McMaster Universities OA index (WOMAC) were assessed at baseline and after 3 months. Baseline results were compared with QoL values in 4800 subjects randomly selected from the general population. Multiple regression analysis was performed to identify determinants of QoL at baseline and measures influencing changes in SF-36 or WOMAC during follow up. RESULTS All QoL dimensions were significantly (p<0.01) decreased in patients with OA compared with controls. Significant improvement (p<0.05) in four dimensions of the SF-36 (vitality, role emotional, role physical, bodily pain) and in all components of the WOMAC was seen between baseline and month 3. Older age, female sex, longer duration of OA, and a higher number of comorbidities were the major determinants of a poor QoL at baseline. Maximal benefit from non-specific NSAIDs was seen in patients with the most severe impairment in QoL and the shortest duration of OA. CONCLUSION OA negatively impacts all dimensions of the QoL. Non-specific NSAIDs improve the QoL in patients with OA treated in a "real life setting". The profile of patients receiving maximal benefit from such treatment may be of interest for health providers, enabling them to decide who should preferentially be given cytoprotective treatments or coxibs.

Abstract
OBJECTIVE To determine predictors of disability depending on whether joint deformity and pain reporting exist independently or concurrently. METHODS Subjects were 154 volunteers for an osteoarthritis screening examination. Eligible subjects completed questionnaires for physical function, pain, and depressive symptoms; underwent evoked pain testing for tenderness assessment; and had anteroposterior and lateral radiographs taken of both knees. Two blinded rheumatologists scored the images using Kellgren-Lawrence criteria to determine presence of deformity. RESULTS Subjects were divided into 3 subgroups based on radiographic evidence of deformity and self-reported pain. Disability was greatest when pain and deformity occurred together (F[2,151] = 18.8, P < 0.0001). Self-reported disability in the absence of deformity was predicted by body mass index, pain threshold, and anxiety symptoms; disability was predicted by the number of osteophytes and depressive symptoms when pain and deformity occurred together. CONCLUSION Self-reported disability in osteoarthritis of the knee is greatest with concurrent pain and joint deformity. When pain and deformity do not cooccur, disability appears to be related to separate factors, including anxiety and pain threshold (e.g., tenderness).

Abstract
OBJECTIVE To investigate the effect of glucosamine sulfate on long-term symptoms and structure progression in postmenopausal women with knee osteoarthritis (OA). DESIGN This study consisted of a preplanned combination of two three-year, randomized, placebo-controlled, prospective, independent studies evaluating the effect of glucosamine sulfate on symptoms and structure modification in OA and post-hoc analysis of the results obtained in postmenopausal women with knee OA. Minimal joint space width was assessed at baseline and after 3 years from standing anteroposterior knee radiographs. Symptoms were scored by the algo-functional WOMAC index at baseline and after 3 years. All primary statistical analyses were performed in intention-to-treat, comparing joint space width and WOMAC changes between groups by ANOVA. RESULTS Of 414 participants randomized in the two studies, 319 were postmenopausal women. At baseline, glucosamine sulfate and placebo groups were comparable for demographic and disease characteristics, both in the general population and in the postmenopausal women subset. After 3 years, postmenopausal participants in the glucosamine sulfate group showed no joint space narrowing [joint space change of +0.003 mm (95% CI, -0.09 to 0.11)], whereas participants in the placebo group experienced a narrowing of -0.33 mm (95% CI, -0.44 to -0.22; P < 0.0001 between the two groups). Percent changes after 3 years in the WOMAC index showed an improvement in the glucosamine sulfate group [-14.1% (95%, -22.2 to -5.9)] and a trend for worsening in the placebo group (5.4% (95% CI, -4.9 to 15.7) (P = 0.003 between the two groups). CONCLUSION This analysis, focusing on a large cohort of postmenopausal women, demonstrated for the first time that a pharmacological intervention for OA has a disease-modifying effect in this particular population, the most frequently affected by knee OA.

Abstract
OBJECTIVE To assess whether improvement in knee pain biased the determination of the structure-modifying effect reported for glucosamine sulfate in two recent 3-year, randomised, placebo-controlled clinical trials, in which conventional standing antero-posterior full extension knee radiographs were used for the measurement of joint space narrowing, and in which pain relief might have improved knee full extension. DESIGN Patients completing the 3-year treatment course were selected based on a WOMAC pain decrease at least equal to the mean improvement in the glucosamine sulfate arms in either of the original studies, irrespective of treatment with glucosamine sulfate or placebo (drug responders or placebo responders). In a second approach, 3-year completers were selected if their baseline standing knee pain (item #5 of the WOMAC pain scale) was 'severe' or 'extreme' and improved by any degree at the end of the trials. In both cases, changes in minimum joint space width were compared between treatment groups. RESULTS Global knee pain was mild-to-moderate in the two study populations and in all patient subsets identified. There were obviously more pain improvers in the glucosamine sulfate subsets (N=76 in the two studies combined) than in the placebo subsets (N=57), but WOMAC pain scores improved to the same extent, which was as large as over 50% relative to baseline. Nevertheless, the placebo subsets in both studies underwent an evident mean (SD) joint space narrowing, which in the pooled analysis of both studies was -0.22 (0.80) mm, and was not observed with glucosamine sulfate: +0.15 (0.60) mm (P=0.003 vs placebo). Similar results were found in the smaller subsets with > or = severe baseline standing knee pain that improved after 3 years, with a joint space narrowing nevertheless of -0.28 (0.76) mm with placebo (N=26), not observed with glucosamine sulfate: +0.21 (0.68) mm (N=31; P=0.014 vs placebo). CONCLUSIONS Knee pain relief did not bias the report of a structure-modifying effect of glucosamine sulfate in two recent long-term trials using conventional standing antero-posterior radiographs, possibly due to the mild-to-moderate patient characteristics.

Abstract
PURPOSE OF REVIEW Several entities have been investigated carefully for the symptomatic and structural management of osteoarthritis. This review reports recent findings suggesting that such compounds may delay the structural progression of osteoarthritis. RECENT FINDINGS The most compelling evidence of a potential for inhibiting the structural progression of osteoarthritis has been obtained with glucosamine sulfate, whereas preliminary results obtained in patients with osteoarthritis of the hands also suggest that chondroitin sulfate could be used in the same indication. At any rate, these two compounds have clearly demonstrated a symptomatic action, mainly in osteoarthritis of the lower limbs. Patients with the less severe radiographic osteoarthritis will experience, in the long run, the most dramatic disease progression in terms of joint space narrowing. Such patients may be particularly responsive to structure-modifying drugs. SUMMARY Glucosamine sulfate has demonstrated its ability to reduce the progression of osteoarthritis in the lower limbs. The preliminary results obtained in the hands suggest that chondroitin sulfate could also be of interest in this indication. An important issue is that all the conclusive studies with such chemical entities resulted from the use of prescription medicines, not over-the-counter pills or food supplements.
