“…There were no differences between responders and non-responders related to age, gender, BMI, Sangha scores and baseline PROM values. The German versions of the following questionnaires were used: Western Ontario and McMaster Osteoarthritis Index (WOMAC) [12], Oxford Hip or Knee Score (OHS, OKS) [13,14], Lower Extremity Functional Scale (LEFS) [15], University of California at Los Angeles (UCLA) activity scale [16] and the EuroQol-5 dimension (EQ-5D) [17, www.euroqol.org]. These instruments were chosen because they are frequently used in outcome studies related to hip and knee replacement, and/or already part of nationwide joint registries, and/or available in different languages, which allows for direct comparisons with the literature.…”

“…These instruments were chosen because they are frequently used in outcome studies related to hip and knee replacement, and/or already part of nationwide joint registries, and/or available in different languages, which allows for direct comparisons with the literature. Evidence of reliability, validity and usefulness of these measures in patients undergoing TJR has been proven in numerous studies before [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The patients were also asked to rate which of the three function-related questionnaires (WOMAC, OHS/OKS and LEFS) they consider the most relevant for assessing their joint problem and which of them the easiest to complete.…”

“…We used the recommended scoring of 0-4 for each item [26]. Hence, total scores can reach from 0 (worst state) to 48 points (best state) [13,14]. The LEFS is a condition-specific (disorders of the lower limb) questionnaire consisting of 20 Likert scale items inquiring for Qual Life Res functional disability with different activities of daily living.…”

BackgroundThe aim of the study was to improve physical activity (PA), well-being and clinical outcome after total knee and hip arthroplasty through tailored activity counselling during inpatient rehabilitation.Methods65 patients (aged 70.4 ± 7.3 years, BMI 28.5 ± 4.3) starting inpatient rehabilitation after primary knee or hip arthroplasty due to osteoarthritis were recruited and pseudo-randomized into an intervention (IG) and a control group (CG). Twice a week, the IG was encouraged to increase their daily step count by 5%. PA, e. g. number of steps, step frequency, or active minutes, was measured by step activity monitoring. Well-being and clinical outcome were assessed using the SF-36, Oxford Knee/Hip Score and Global rating of Change. Procedures were conducted at the onset of inpatient rehabilitation, and repeated one and 6 months after inpatient rehabilitation.ResultsData sets were obtained from 49 patients (IG: n = 23, CG: n = 26). Both groups significantly increased their number of daily steps from the 1 month to the 6 months follow up after rehabilitation: CG: 9019 (95%CI: 7812, 10,226), IG: 9280 (7972, 10,588) and CG: 10921 (9571, 12,271), IG: 11326 (9862, 12,791) respectively. Additionally, well-being and clinical outcome improved significantly in both groups. No significant differences in physical activity, clinical outcome and well-being were found between the groups.ConclusionsPA counselling during inpatient rehabilitation does not improve PA, well-being and clinical outcome in patients with primary knee or hip arthroplasty in addition to the rehabilitation program. PA interventions may be more effective after the completion of the inpatient rehabilitation phase.Trial registrationDRKS DRKS00012682. Registered retrospectively on 03–07- 2017.

Purpose The aim of this study was to evaluate laxity in knees with pre-operative (preop) valgus alignment compared to knees with pre-operative varus alignment after total knee arthroplasty (TKA). Methods This was a retrospective study including 81 patients, with six years follow-up, for pre-operative valgus-or varus alignment of the leg. All patients had been supplied with the same cruciate retaining (CR) TKA with rotating platform. Clinical findings were assessed by KSS, OKS and IKDC 2000 score. Rotational knee laxity was evaluated by a validated instrument (Laxitester®) with 2 Nm torque in 30°flex-ion. Collateral ligament laxity was tested manually in 30°f lexion with a bending moment of approximately5 Nm. Biomechanical results were compared to the contralateral side. Results Thirty-one patients had a preop valgus alignment of 8.96°and 50 patients a varus leg axis of 4.99°in the mean. In the preop valgus knees rotational analysis showed an increased laxity of 10.7°compared to preop varus knees (p=0.001). There was no significant difference in medial (valgus 2.6 mm, varus 2.5 mm) and lateral (valgus 2.8 mm, varus 2.7 mm) laxity. KSS and OKS showed no significant differences in the follow-up results. In the IKDC 2000 objective score 50 % of the preop varus knees and 25.8 % of the preop valgus knees were classified as nearly normal. The difference in the IKDC objective was highly significant (p<0.001). Conclusion Preop valgus knees show a significantly increased rotational laxity but no increased collateral ligament laxity compared to pre-operative varus knees six years after TKA with rotating platform. There is a significant difference in IKDC objective.
