Associations between biomarkers and histological assessment in individual animals in a destabilization of the medial meniscus (DMM) model of osteoarthritis (OA) / Seon Young Choi in Acta Orthopaedica Belgica, Vol. 87/4 (Décembre 2021)
[article]
Titre : Associations between biomarkers and histological assessment in individual animals in a destabilization of the medial meniscus (DMM) model of osteoarthritis (OA) Type de document : texte imprimé Auteurs : Seon Young Choi ; Jiheon Rhim ; Woo-Jung Han Année de publication : 2021 Article en page(s) : p. 712-721 Note générale : https://doi.org/10.52628/87.4.16 Langues : Anglais (eng) Mots-clés : osteoarthritis biomarker destabilization of the medial meniscus Résumé : To date, the use of biomarkers for assessing individual severity of osteoarthritis (OA) is limited, and the correlation of histological scores with biomarkers for individual animals in the destabilization of the medial meniscus (DMM) model of OA has not been well investigated. Accordingly, this study investigated how well representative biomarkers in the DMM model reflected specific changes in individual animals.
Rats were randomly divided into the OA group and the sham group. OA model was established by destabilization of the medial meniscus (DMM). After 2,4,6,8,10 and 12 weeks (n=14, each week), the concentrations of CTXII, COMP, C2C, and OC in serum were measured, and cartilage degeneration, osteophytes, and synovial membrane inflammation, typical of OA, were scored using Osteoarthritis Research Society International (OARSI) scoring system. Additionally, the correlation between each biomarker and the specific changes in osteoarthritis was analyzed for individual animals using the Generalized Estimating Equation (GEE).
Statistical analysis showed a low correlation between CTXII and osteophyte score of the medial femur (coefficient = -0.0088, p= 0.0103), COMP and osteophyte score of the medial tibia (coefficient = -0.0911, p= 0.0003), and C2C and synovial membrane inflammation scores of the medial femoral (coefficient = 0.054, p= 0.0131).
These results suggest that representative OA bio- markers in individual animals in the DMM model did not reflect histological scores well.Permalink : ./index.php?lvl=notice_display&id=102051

Titre : Limited effect of a self-management exercise program added to spa therapy for increasing physical activity in patients with knee osteoarthritis : A quasi-randomized controlled trial Type de document : texte imprimé Auteurs : Chloé Gay ; Candy Guiguet-Auclair ; Nicolas Coste ; Nathalie Boisseau ; Laurent Gerbaud ; Bruno Pereira ; Emmanuel Coudeyre Année de publication : 2020 Article en page(s) : p. 181-188 Note générale : doi.org/10.1016/j.rehab.2019.10.006 Langues : Anglais (eng) Mots-clés : Physical activity level Exercise Osteoarthritis Education Self-management Résumé : Background
The efficacy of spa therapy in osteoarthritis (OA) has ever been demonstrated, with a good level of evidence for pain and disability. The effect of a self-management program with spa therapy on physical activity (PA) level has never been demonstrated.
Objective
This study aimed to assess, at 3 months, the effectiveness of 5 sessions of a self-management exercise program in patients with knee OA (KOA) who benefit from 18 days of spa therapy and received an information booklet (on proposed physical exercises) on improvement in at least one PA level.
Methods
This was an interventional, multicentre, quasi-randomized controlled trial with a cluster randomized design (1-month period). People 50 to 75 years old with symptomatic knee OA were included in 3 spa therapy centres in France (Bourbon Lancy, Le Mont Dore, Royat). Both groups received conventional spa therapy sessions during 18 days and an information booklet on the benefits of PA practice for KOA. The intervention group additionally received 5 self-management exercise sessions. The main outcome was improvement in at least one PA level according to the International Physical Activity Questionnaire (IPAQ) short-form categorical score (low to moderate or high, or moderate to high) at 3 months. Secondary outcomes were the evolution of PA (MET-min/week), disability, pain, anxiety, depression, self-efficacy, fears and beliefs concerning KOA, barriers to and facilitators of regular PA practice, consumption of painkillers and adherence to physical exercise program at 3 months. Assessors but not participants or caregivers were blinded.
Results
In total, 123 patients were randomized, 54 to the intervention group and 69 to the control group. Considering the main outcome, at 3 months, 37% of patients in the intervention group showed improvement in at least one PA level according to the IPAQ categorical score versus 30.4% in the control group (P = 0.44). In the intervention group, 13 (24.1%) patients showed improvement from low to moderate PA level (vs. 8 [11.6%] in the control group), 2 (3.7%) from low to high (vs. 2 [2.9%]) and 5 (9.3%) from moderate to highvs. 11 [15.9%]). Both intervention and control groups showed increased IPAQ continuous scores (MET-min/week) at 3 months, although not significantly. HAD anxiety and depression scores were significantly reduced in the intervention group (P = 0.001 and P = 0.049, respectively) and the perception of PA was better in the intervention than control group for motivation and barriers scores (P = 0.019 and P = 0.002, respectively).
Conclusions
This study showed the lack of impact of a short self-management program on PA level in addition to 18-day spa therapy for KOA, but both intervention and control groups showed improved PA level.Permalink : ./index.php?lvl=notice_display&id=90793

Twenty-nine spontaneous osteonecrosis of the knee (SONK) cases were reviewed retrospectively. An equal number of patients with osteoarthritis (OA) performed in the same period were selected and matched with respect to age, preoperative range of motion and radiological grade of knee arthrosis. The mean follow up time were 44.14 ± 14.05 and 44.45 ± 14.45 months, respectively. The preoperative hospital for special surgery knee score and visual analogue score were significantly better in group OA than those of group SONK. However, the results were comparable in terms of postoperative pain, knee score, range of motion and axial alignment. From a technical point of view, the osteonecrosis stage and bone defect must be taken into account when using UKA for SONK. Permalink : ./index.php?lvl=notice_display&id=40665

Since these registries may con- tain confounding factors, we conducted a single center cohort study comparing survival and reason for failure between THA for an acute femoral neck fracture and OA using the same hip prosthesis after a minimum follow-up of 2 years.
We retrospectively analyzed 2782 patients who had undergone THA with an Accolade TMZF stem and a Trident cup between March 2009 and September 2014. Primary diagnosis before THA was osteoarthritis (OA group : n=2610) or acute femoral fracture (Fracture group : n=172). Patients in both groups were operated on by the same hip surgeons. Effect of diagnosis on THA survival was analyzed using Cox-regression analysis. Chi-square tests were used to illustrate the different reasons for revision between the groups.
Mean follow-up was 4.6 years (2-7.6). A total of 100 revisions were performed. The revision risk was comparable between the OA and Fracture group (HR=1.04, 95% CI :0.46-2.39). No differences were found between the OA and Fracture group with respect to the occurrence of periprosthetic fractures (0.8% vs. 0.6%, p=0.71) and revisions for dislocation (0.6% vs. 1.2%, p=0.38).
We found no difference in outcome or reason for revision between THA for OA or femoral neck frac- ture. Using an implant with a proven ODEP rating and having experienced hip surgeons carry out the procedures may be more important than the primary diagnosis.Permalink : ./index.php?lvl=notice_display&id=96669

Furthermore, there is no clear consensus in literature about the postoperative alignment goals following HTO. A retrospective case series was performed to evaluate return to sport and work following open wedge HTO.
The University of California, Los Angeles scale, the German classification system according to the Reichsausschuß für Arbeitszeitermittlung, the Tegner score and the Knee injury and Osteoarthritis Outcome Score were used to asses the employment status, sport status and clinical outcome at the time of surgery and at final follow-up, minimum 2 years after surgery. The pre- and postoperative hip knee ankle angle (HKA) were documented. The desired postoperative alignment target was 0°-2° valgus mechanical axis.
30 open wedge HTOs were performed of which 27 patients were retrospectively included in the study. 25 out of 26 patients returned to work and 15 out of 17 patients returned to sport following surgery. Outcome scores were significantly higher after surgery. The mean postoperative HKA was 0,9° of valgus mechanical axis.
This study shows excellent outcome in sport and work activity and clinical outcome after open wedge HTO. We furthermore suggest that these outcomes can be obtained with a postoperative alignment of 0°-2° of valgus mechanical axis.Permalink : ./index.php?lvl=notice_display&id=96595
