A survey of patient and medical professional perspectives on implementing osteoarthritis management programs for hip and knee osteoarthritis.

BACKGROUND: Strategies are needed to improve referral into, and uptake of, osteoarthritis (OA) management programs. This survey investigated and compared patients' and medical professionals' views around hip and knee OA management and factors impacting implementation of an osteoarthritis management program. METHODS: As part of a mixed-methods program of research, patients with hip or knee OA and medical professionals routinely involved in the management of OA, were invited to complete a comprehensive online survey. All data were analysed descriptively or using chi squared tests. Survey findings for factors perceived to impact implementation of an OA management programme were triangulated with previously reported qualitative data. RESULTS: Fifty-three patients (38 females, 15 males) and 32 medical professionals (orthopaedic surgeons, sports physicians, rehabilitation physicians, rheumatologists and general practitioners) completed the survey. Twenty-eight patients (53%) had prior participation in the OA management programme (GLA:D® ) and 19 medical professionals (59%) had previously referred patients to the programme. Of the participants with prior exposure, 21 patients (75%) and 15 medical professionals (79%) agreed the programme was beneficial. A higher proportion of medical professionals, compared to patients, believed weight loss (100% vs. 67%), injection therapy (50% vs. 21%), hip replacement (100% vs. 62%) and knee replacement (97% vs. 62%) were effective treatments, with no differences for all other treatments. The barriers and enablers identified for referral into, and participation in, an OA management programme mostly aligned to factors identified in previous related qualitative research. Divergent factors in the survey included patients concerns about doing exercise-therapy with 81% (higher than expected) not reporting any concerns about exercising, and 19% (lower than expected) concerned about their OA joint, such as making their pain worse. CONCLUSIONS: This study has extended our understanding of barriers and enablers for referral into, and participation in, an OA management programme with a lower than expected number of patients being concerned about exercising due to their OA joint. Patients and medical professionals had positive views relating to the quality of the programme delivery, patient satisfaction and programme effectiveness. Medical professionals were more likely than patients to consider weight loss, injections and joint replacement as effective treatment options.

Kinematic alignment in total knee arthroplasty: a five-year prospective, multicentre, survivorship study.

AIMS: The mid-term results of kinematic alignment (KA) for total knee arthroplasty (TKA) using image derived instrumentation (IDI) have not been reported in detail, and questions remain regarding ligamentous stability and revisions. This paper aims to address the following: 1) what is the distribution of alignment of KA TKAs using IDI; 2) is a TKA alignment category associated with increased risk of failure or poor patient outcomes; 3) does extending limb alignment lead to changes in soft-tissue laxity; and 4) what is the five-year survivorship and outcomes of KA TKA using IDI? METHODS: A prospective, multicentre, trial enrolled 100 patients undergoing KA TKA using IDI, with follow-up to five years. Alignment measures were conducted pre- and postoperatively to assess constitutional alignment and final implant position. Patient-reported outcome measures (PROMs) of pain and function were also included. The Australian Orthopaedic Association National Joint Arthroplasty Registry was used to assess survivorship. RESULTS: The postoperative HKA distribution varied from 9° varus to 11° valgus. All PROMs showed statistical improvements at one year (p < 0.001), with further improvements at five years for Knee Osteoarthritis Outcome Score symptoms (p = 0.041) and Forgotten Joint Score (p = 0.011). Correlation analysis showed no difference (p = 0.610) between the hip-knee-ankle and joint line congruence angle at one and five years. Sub-group analysis showed no difference in PROMs for patients placed within 3° of neutral compared to those placed > 3°. There were no revisions for tibial loosening; however, there were reports of a higher incidence of poor patella tracking and patellofemoral stiffness. CONCLUSION: PROMs were not impacted by postoperative alignment category. Ligamentous stability was maintained at five years with joint line obliquity. There were no revisions for tibial loosening despite a significant portion of tibiae placed in varus; however, KA executed with IDI resulted in a higher than anticipated rate of patella complications.Cite this article: Bone Jt Open 2022;3(8):656-665.

Exploring views of orthopaedic surgeons, rheumatologists and general practitioners about osteoarthritis management.

BACKGROUND: Delivery of recommended treatments for hip and knee osteoarthritis (OA) is known to be discordant with guideline recommendations. However, professional views related to OA management across medical and surgical disciplines are not well understood. The aim of this study was to explore the views of medical professionals about management of hip and knee OA. METHODS: Qualitative study. Semistructured individual interviews were conducted with orthopaedic surgeons, rheumatologists and general practitioners routinely involved in the management of OA. Interviews were audiotaped, transcribed, member-checked, coded and thematically analysed. RESULTS: Fifteen medical professionals were interviewed. Three main themes were: (i) recognition of the importance of nonsurgical management of hip and knee OA, focussed on self-management, exercise-therapy, weight management and analgesia; (ii) joint replacement being considered the 'last resort' for end stage disease not responding to nonsurgical management; and (iii) determination of management 'success' through patient perceptions was more common than the use of validated instruments. Views on management broadly converged across disciplines, except for the role of joint replacement, considered an adjunct in the overall management of OA by rheumatologists and as a definitive cure by orthopaedic surgeons. CONCLUSIONS: Aligning with current guidelines, medical professionals recognised the importance of nonsurgical management focussed on exercise-therapy for hip and knee OA, and concurred that joint replacement surgery should be a last resort. A focus on patient education was less prominent, which along with implementation of validated outcome measures in routine medical practice, may require greater health system support.

Barriers and enablers to uptake of a contemporary guideline-based management program for hip and knee osteoarthritis: A qualitative study.

Objective: To explore barriers and enablers for referral to, and participation in, a contemporary guideline-based osteoarthritis management program - Good Life with osteoArthritis in Denmark (GLA:D Australia). Design: A qualitative design was used, involving semi-structured interviews with patients with osteoarthritis and medical professionals. Interviews were audiotaped, transcribed verbatim, coded and thematically analysed. Barrier and enabler themes were mapped to the theoretical domains framework and used to inform the development of recommendations for improving uptake of guideline-based osteoarthritis management programs. Results: Twenty patients with hip and/or knee osteoarthritis and 15 medical professionals (5 general practitioners, 4 rheumatologists, 6 orthopaedic surgeons) were included. Across both groups, three themes emerged as barriers (program access; misinformation about osteoarthritis; patient and program factors), one theme emerged as a barrier and enabler (health professional trust, feedback and advice), and two themes emerged as enablers (opportunity to achieve positive outcomes and potentially avoid joint replacement surgery; better program promotion, patient and health professional education, and efficient referral processes). Conclusions: Optimising uptake of guideline-based osteoarthritis management programs requires improved reimbursement models, and better promotion and educational initiatives for patients and medical professionals. A particular focus of education should include dispelling misinformation about osteoarthritis, and highlighting the safety and value of physiotherapist delivered exercise-therapy.

Intra-operative reliability of ShapeMatch cutting guide placement in total knee arthroplasty.

Custom cutting guides based on pre-operative imaging have been introduced for total knee arthroplasty (TKA). The aim of this prospective cohort study was to assess the reliability of repeated placement of custom cutting guides by multiple surgeons in a group of patients undergoing TKA. Custom cutting guides (ShapeMatch®, Stryker Orthopaedics) were designed from pre-operative MRI scans. The treating surgeon placed each guide on the femur and tibia of each patient three times without pinning the block. The three-dimensional position and orientation of the guide was measured for each repetition using a computer navigation system. The surgeon was blinded to the navigation system display. Data from 24 patients and 6 surgeons were analyzed. Intraclass correlation coefficients for all measurement parameters were in the range 0.889-0.997 (excellent), and all comparisons were statistically significant (p < 0.001). The range for femoral varus/valgus was 0.0-1.5°, with 96% of patients being within 0.5°. For femoral flexion/extension the range was 0.0-3.5° (92% within 2.5°). On the tibia, varus/valgus had a range of 0.0-1.0° (92% within 0.5°), and for slope the range was 0.0-3.5° (92% within 2.5°). The high degree of agreement indicated that intra-surgeon variation was minimal and that the technique is reliable.
