Objective: To compare biomechanical and clinical outcome of laterally wedged insoles (LWI) and an ankle-foot orthosis (AFO) in patients with medial knee osteoarthritis. Design: Single-centre, block-randomized, cross-over controlled trial. Setting: Outpatient clinic. Subjects: About 39 patients with symptomatic medial knee osteoarthritis. Interventions: Patients started with either LWI or AFO, determined randomly, and six weeks later changed to the alternative. Main measures: Change in the 1st maximum of external knee adduction moment (eKAM) was assessed with gait analysis. Additional outcomes were other kinetic and kinematic changes and the patient-reported outcomes EQ-5D-5L, Oxford Knee Score (OKS), American Knee Society Clinical Rating System (AKSS), Hannover Functional Ability Questionnaire – Osteoarthritis and knee pain. Results: Mean age (SD) of the study population was 58 (8) years, mean BMI 30 (5). Both aids significantly improved OKS (LWI P = 0.003, AFO P = 0.001), AKSS Knee Score (LWI P = 0.01, AFO P = 0.004) and EQ-5D-5L Index (LWI P = 0.001, AFO P = 0.002). AFO reduced the 1st maximum of eKAM by 18% ( P < 0.001). The LWI reduced both maxima by 6% ( P = 0.02, P = 0.03). Both AFO and LWI reduced the knee adduction angular impulse (KAAI) by 11% ( P < 0.001) and 5% ( P = 0.05) respectively. The eKAM (1st maximum) and KAAI reduction was significantly larger with AFO than with LWI ( P = 0.001, P = 0.004). Conclusions: AFO reduces medial knee load more than LWI. Nevertheless, no clinical superiority of either of the two aids could be shown.

Abstract Background The degree to which a validated instrument is able to detect clinically significant change over time is an important issue for the better management of hip or knee replacement surgery. This study examines the internal responsiveness of the EQ-5D-3L, the Oxford Hip Score (OHS), and the Oxford Knee Score (OKS) by various methods. Data from NHS patient-reported outcome measures (PROMs) linked to the Hospital Episodes Statistics (HES) dataset (2009–2015) was analysed for patients who underwent primary hip surgery (N = 181,424) and primary knee surgery (N = 191,379). Methods Paired data-specific univariate responsiveness was investigated using the standardized response mean (SRM), the standardized effect size (SES), and the responsiveness index (RI). Multivariate responsiveness was furthermore examined using the defined capacity of benefit score (i.e. paired data-specific MCID), adjusting baseline covariates such as age, gender, and comorbidities in the Box-Cox regression models. The observed and predicted percentages of patient improvement were examined both as a whole and by the patients' self-assessed transition level. Results The results showed that both the OHS and the OKS demonstrated great univariate and multivariate responsiveness. The percentages of the observed (predicted) total improvement were high: 51 (54)% in the OHS and 73 (58)% in OKS. The OHS and the OKS showed distinctive differences in improvement by the 3-level transition, i.e. a little better vs. about the same vs. a little worse. The univariate responsiveness of the EQ-5D-3L showed moderate effects in total by Cohen’s thresholds. The percentages of improvement in the EQ-5D-3L were moderate: 44 (48)% in the hip and 42 (44)% for the knee replacement population. Conclusions Distinctive percentage differences in patients’ perception of improvement were observed when the paired data-specific capacity of benefit score was applied to examine responsiveness. This is useful in clinical practice as rationale for access to surgery at the individual-patient level. This study shows the importance of analytic methods and instruments for investigation of the health status in hip and/or knee replacement surgery. The study finding also supports the idea of using a generic measure along with the disease-specific instruments in terms of cross-validation.

Arthrofibrotic stiffness of the knee joint has been recognized as a highly debilitating complication after complex knee reconstruction. The clinical impact of arthroscopic revision surgery was evaluated for patients with knee arthrofibrosis following total knee arthroplasty (TKA) and after joint preserving procedures. Hypothesis: Arthroscopic revision surgery is associated with functional benefits in both groups. We retrospectively reviewed a consecutive series of adult patients (#CHR: greaterlike#18 years) at a single institution who underwent arthroscopic revision for knee stiffness. Minimum follow-up: 24 months. The analysis included demographic, surgical and histological data. The following outcome parameters were evaluated: pain (Visual Analog Scale, VAS); objective score systems (Oxford Knee Score) and patient activity (Tegner Activity Scale (TAS), Univ. of California Activity Scale (UCLA)). Furthermore, range of motion (ROM) was compared pre-, intra- and postoperatively. Finally, we compared body mass index (BMI) and quality of life (EQ-5D) changes. We identified a total of 57 patients who underwent arthroscopic adhesiolysis for knee arthrofibrosis: 45 after TKA (Group 1) and 12 patients with ligament reconstruction (Group 2). The patient cohort included thirty (43.5%) males and thirty-six (56.5%) females. Mean age was 69 (SD 10.6) years in the TKA group and 41 (SD 12.7) years in group 2 (p=0.01). Mean length of stay (LOS) was 4.6 days in Group 1 and 2.8 days in Group 2. Pain levels (VAS) were reduced significantly in both groups (p=0.004); from 7.5 to 4.8 in Group 1 and from 7.8 to 2.9 (Group 2). In terms of sports activity, 26 patients (37.7%) reported an improved sports activity (UCLA score). The TAS improved from 2.58 to 4.08 in Group 2. The Oxford Knee Score improved from 23.5 to 27.2 in Group 1 and from 16.5 to 36.3 in Group 2. No reduction in BMI was observed. However, quality of life (EQ-5D) improved from 47.6 to 51.9 Group 1; and from 52.9 to 71.7 in Group 2. Arthroscopic revision of the stiff knee may offer clinical benefits in terms of significant pain reduction, an improved level of activity and quality of life in stiffness following both TKA and joint preserving surgical reconstruction.

AbstractRoutine use of biological therapies is in its early stages. Techniques involve stem cells, platelet preparations, recombinant growth factors and autologous conditioned serum, often combined with surgery. The objective of this case analysis was to document effects of intra-articular autologous conditioned serum injections in outpatients with knee pain associated with meniscal defects. Autologous conditioned serum was prepared from patients’ blood by centrifugal separation from cellular components using a specialized device (EOT®II, Orthokine). Outpatients (n=47) with heterogeneous knee meniscus lesions (76.6% traumatic knee injury) were injected once weekly (average 5.2 applications). Average age was 48.6 years (range 21–79). Oxford Knee Score and structural changes with the MRI Boston Leeds Osteoarthritis Knee Score were documented at baseline and 6 months. All analyses were performed retrospectively.In 83% patients, surgery was avoided during the 6-month observation period. Oxford Knee Score improved significantly from 29.1–44.3 (p<0.001; best possible score=48). Structural findings on MRI, measured by Boston Leeds Osteoarthritis Knee Score, showed significant improvement at 6 months (0.82–0.71, p<0.001). This retrospective study implies that intra-articular autologous conditioned serum injection may be an effective treatment option for knee pain associated with meniscal lesions. Controlled studies of autologous conditioned serum treatment for meniscal lesions are advocated.

Aims This study aimed to identify the tibial component and femoral component coronal angles (TCCAs and FCCAs), which concomitantly are associated with the best outcomes and survivorship in a cohort of fixed-bearing, cemented, medial unicompartmental knee arthroplasties (UKAs). We also investigated the potential two-way interactions between the TCCA and FCCA. Methods Prospectively collected registry data involving 264 UKAs from a single institution were analyzed. The TCCAs and FCCAs were measured on postoperative radiographs and absolute angles were analyzed. Clinical assessment at six months, two years, and ten years was undertaken using the Knee Society Knee score (KSKS) and Knee Society Function score (KSFS), the Oxford Knee Score (OKS), the 36-Item Short-Form Health Survey questionnaire (SF-36), and range of motion (ROM). Fulfilment of expectations and satisfaction was also recorded. Implant survivorship was reviewed at a mean follow-up of 14 years (12 to 16). Multivariate regression models included covariates, TCCA, FCCA, and two-way interactions between them. Partial residual graphs were generated to identify angles associated with the best outcomes. Kaplan-Meier analysis was used to compare implant survivorship between groups. Results Significant two-way interaction effects between TCCA and FCCA were identified. Adjusted for each other and their interaction, a TCCA of between 2° and 4° and a FCCA of between 0° and 2° were found to be associated with the greatest improvements in knee scores and the probability of fulfilling expectations and satisfaction at ten years. Patients in the optimal group whose TCCA and FCCA were between 2° and 4°, and 0° and 2°, respectively, had a significant survival benefit at 15 years compared with the non-optimal group (optimal: survival = 100% vs non-optimal: survival = 92%, 95% confidence interval (CI) 88% to 96%). Conclusion Significant two-way interactions between the TCCA and FCCA demonstrate the importance of evaluating the alignment of the components concomitantly in future studies. By doing so, we found that patients who concomitantly had both a TCCA of between 2° and 4° and a FCCA of between 0° and 2° had the best patient-reported outcome measures at ten years and better survivorship at 15 years.
