AbstractThe purpose of this study was to investigate the interobserver and intraobserver reliabilities of four different radiographic grading scale of osteoarthritis (OA) of the knee joint, namely, Kellgren–Lawrence (KL), Ahlback, Brandt, and OA Research Society International (OARSI). One consultant orthopaedic surgeon and one rheumatologist who were familiar with these OA grading scales participated in the study. Radiological assessments were performed in random order by each observer on two separate occasions, at least 2 weeks apart. K-statistics were used to establish a relative level of agreement between the observers for the two readings and between separate readings by the same observer. A total of 140 patients (53 males and 87 females) with a mean age of 61.2 years (range, 50–72 years) were included in the study. Intraobserver reliability for KL was substantial for observer A (κ: 0.753) and moderate for observer B (κ: 0.573). Interobserver reliability for KL was moderate for both observers (κ: 0.499 and 0.458, respectively). Intraobserver reliability for Ahlback was substantial for observer A (κ: 0.768) and moderate for observer B (κ: 0.561). Interobserver reliability for Ahlback was fair for both observers (κ: 0.365 and 0.204, respectively). Intraobserver reliability for Brandt was substantial for observer A (κ: 0.741) and moderate (κ: 0.425) for observer B. Interobserver reliability for Brandt was fair for both observers (κ: 0.308 and κ: 0.246, respectively). Intraobserver reliability for OARSI was substantial for observer A (κ: 0.792) and moderate for observer B (κ: 0.508). Interobserver reliability for OARSI was moderate for observer A (κ: 0.425) and slight for observer B (κ: 0.175). None of the studied OA grading scales showed acceptable reliability (κ > 0.80). The evaluation of patients with OA should not be dependent on radiographic findings alone; clinical findings should also guide the treatment and follow-up.

Background: Osteoarthritis (OA) of the knee is a major public health issue. It is important to have a clear understanding about the relationship between clinical features (Pain, functional impairment) and radiographic findings to select appropriate treatment option. Objectives: To investigate the relationship between pain, loss of physical function, and radiographic findings in OA of the knee joint. Materials and Methods: A cross sectional study on 90 patients aged 40 years and above with OA of the knee joint selected randomly. Severity of the knee pain and functional impairment were measured using the Bangla version of WOMAC (Western Ontario and McMaster Universities Osteoarthritis index). Radiograph of the knee joint were assessed with the Kellgren- Lawrence grading scale. Results: The mean of the age, BMI (body mass index) and duration of pain was respectively 54.2 (± 9.5) years, 26.0 (± 3.4) kg/m2 and 3.6 (± 2.8) years. Male female ratio was 1:1.6. 55% of the patients had the Visual Analogue Scale (VAS) score of 1-3. The Pain and physical function were associated with OA of the knee where the mean physical function score was 45.1 ± 4.2 in patients who had pain score of >10. However pain and physical function was not associated with the radiographic findings of the OA of the knee. Conclusion: The treatment planning for the OA of the knee should be based on clinical presentation rather than radiographic findings. KYAMC Journal Vol. 10, No.-4, January 2020, Page 173-178

Total ankle replacement (TAR) is a viable alternative to ankle fusion in certain patients with end-stage ankle arthritis. Despite the importance of understanding alignment and movement of the prosthesis, there is no standardized radiographic method for evaluating the position and movement of the INBONE 2 prosthesis. The aims of this study were to describe a radiographic measurement protocol for INBONE 2 for clinical practice and research while determining the interobserver and intraobserver reliability using standard weightbearing radiographs. Fifteen patients were randomly selected with operative dates from January 2011 to January 2014 who underwent primary TAR using the INBONE 2 prosthesis. Most recent preoperative and first postoperative weightbearing anteroposterior and lateral radiographs were pulled and deidentified. Three foot and ankle surgeons blinded from the patient selection and deidentification, measured the described measurements on separate occasions. Intraobserver reliability: surgeon 1 had acceptable reliability for 9 of 13 continuous radiographic measurements (69.2%), surgeon 2 had acceptable reliability for 8 of 13 measurements (61.5%), and surgeon 3 had acceptable reliability for 12 of 13 measurements (92.3%). Interobserver reliability: among the first measurements, 6 of 13 continuous radiographic measurements (46.2%) had acceptable reliability. Among the second measurements, 7 of 13 measurements (53.8%) had acceptable reliability. Among the first and second measurements combined, 7 of 13 measurements (53.8%) had acceptable reliability. This study promotes the need for meticulous evaluation of annual radiographic findings following TAR in an effort to avoid catastrophic failure and represents moderate agreement can be obtained by employing the proposed measurements for surveillance of INBONE 2 TAR at annual postoperative visits. Measurements on the anteroposterior radiograph appear to demonstrate more consistent results for surveillance than lateral measurements. The intraobserver reliability results were somewhat superior to the interobserver reliability, implying more relevance for a single surgeon applying these measurements annually for postoperative surveillance.

Abstract Background The assessment of improvement or maintenance of joint health in healthy subjects is a great challenge. The aim of the study was the evaluation of a joint stress test to assess joint discomfort in subjects with activity-related knee joint discomfort (ArJD). Results Forty-five subjects were recruited to perform the single-leg-step-down (SLSD) test (15 subjects per group). Subjects with ArJD of the knee (age 22–62 years) were compared to healthy subjects (age 24–59 years) with no knee joint discomfort during daily life sporting activity and to subjects with mild-to-moderate osteoarthritis of the knee joint (OA, Kellgren score 2–3, age 42–64 years). The subjects performed the SLSD test with two different protocols: (I) standardization for knee joint discomfort; (II) standardization for load on the knee joint. In addition, range of motion (ROM), reach test, acute pain at rest and after a single-leg squat and knee injury, and osteoarthritis outcome score (KOOS) were assessed. In OA and ArJD subjects, knee joint discomfort could be reproducibly induced in a short time interval of less than 10 min (200 steps). In healthy subjects, no pain was recorded. A clear differentiation between study groups was observed with the SLSD test (maximal step number) as well as KOOS questionnaire, ROM, and reach test. In addition, a moderate to good intra-class correlation was shown for the investigated outcomes. Conclusions These results suggest the SLSD test is a reliable tool for the assessment of knee joint health function in ArJD and OA subjects to study the improvements in their activities. Further, this model can be used as a stress model in intervention studies to study the impact of stress on knee joint health function.

BackgroundComparative studies of platelet-rich plasma (PRP) and hyaluronic acid show variable results. PurposeA review was conducted to understand the current role of PRP and its efficacy versus hyaluronic acid in osteoarthritis (OA) of the knee joint. MethodsOut of 170 identified studies, 14 studies involving 1575 patients with 637 males and 938 females were selected based on PRISMA flow chart guidelines and were analyzed for the study. ResultsA standard PRP regimen consisting of 2–3 intra-articular injections (IA) of 4–6 mL of leucocyte poor PRP at 1–2 weekly intervals provides a better result than HA during the first 3–6 months, and which may continue up to one year. PRP and HA may have synergistic effect; pain and swelling are the two most com-mon complications with PRP, the incidence is more with leucocyte rich PRP (LP-PRP) and intra-osseous PRP treatment.ConclusionPRP provides hope and is more effective than hyaluronic acid in pain relief and improving the quality of life in mild to moderate osteoarthritis of the knee joint. However, hype, that is effective in all, irrespective of grades of OA, mal-aligned or stiff knee, ligamentous laxity, and can avoid joint replacement is a big hindrance in establishing it as a preferred treatment in OA knee. The author follows the above-mentioned PRP regimen; and recommends to combine leucocyte poor PRP with HA for IA injections & with LP-PRP injections along with the two most common painful points (medial collateral ligament, pesanisernius) in a highly painful OA knee. PRP may not address extra-articular causes of knee pain (mal-alignment, muscle wasting, tendinosis), should be corrected for optimum outcome. Contact sports, running, exercises putting pressure on knee and NSAID should be avoided during PRP treatment. Also, more randomized controlled trials are required to further standardize the PRP preparation, administration, injection interval & proper documentation of efficacy and complications in the regenerative registry.

The purpose of the study was to investigate the regenerative processes in the knee joint of rabbits with experimental osteoarthritis after using of allogeneic bone marrow stem cells and a traditional treatment with the non-steroidal anti-inflammatory drug Meloxicam. For the experiment were used 27 male California rabbits (males). Three groups of animals were formed: a control group; the first experimental group treated by the traditional method; the second experimental group treated with allogeneic mesenchymal stem cells (MSC). Animals in the three groups were subjected to osteoarthritis of the knee joint by double injection of 3.44% retinol acetate into the joint cavity at a dose of 1 ml at intervals of 7 days. Tissue from the affected site was sampled for histological examination at 7, 14 and 28 days. The histological sections were stained with haematoxylin-eosin and examined under a microscope. It has been established that intra-articular administration of 3.5 × 106 cells of allogeneic MSCs in experimental osteoarthritis contributes to the restoration of the superficial layer of cartilage, as evidenced by the formation of columns of chondrocytes in the middle layer of articular cartilage and the appearance of isogenic groups of cartilage cells with basophilic cytoplasm in the matrix, uniform articular surface. The use of the traditional method of treating rabbits using the drug Meloxicam is accompanied by incomplete chondrogenesis: part of the chondrocytes is localized in typical chambers, in some cases chondrocyte chambers did not differentiate; articular cartilage had unequal thickness, cell placement was uneven.
