Abstract
OBJECTIVE To estimate patient acceptable symptom state (PASS) and treatment failure (TF) threshold values for Work Productivity and Activity Impairment (WPAI) measure and EQ-5D-5L among people with hip or knee osteoarthritis (OA) 3 and 12 months following participation in a digital self-management intervention (Joint Academy®). METHODS Among the participants, we computed work and activity impairments scores (both 0-100, with a higher value reflecting higher impairment) and the Swedish hypothetical- (range: - 0.314 to 1) and experience-based (range: 0.243-0.976) EQ-5D-5L index scores (a higher score indicates better health status) at 3- (n = 14,607) and 12-month (n = 2707) follow-ups. Threshold values for PASS and TF were calculated using anchor-based adjusted predictive modeling. We also explored the baseline dependency of threshold values according to pain severity at baseline. RESULTS Around 42.0% and 48.3% of the participants rated their current state as acceptable, while 4.2% and 2.8% considered the treatment had failed at 3 and 12 months, respectively. The 3-month PASS/TF thresholds were 16/29 (work impairment), 26/50 (activity impairment), 0.92/0.77 (hypothetical EQ-5D-5L), and 0.87/0.77 (the experience-based EQ-5D-5L). The thresholds at 12 months were generally comparable to those estimated at 3 months. There were baseline dependencies in PASS/TF thresholds with participants with more severe baseline pain considering poorer (more severe) level of WPAI/EQ-5D-5L as satisfactory. CONCLUSION PASS and TF threshold values for WPAI and EQ-5D-5L might be useful for meaningful interpretation of these measures among people with OA. The observed baseline dependency of estimated thresholds limits their generalizability and values should be applied with great caution in other settings/populations.

Abstract
BACKGROUND Sports function and psychological readiness to return to sports (RTS) are important outcomes when evaluating rehabilitation after anterior cruciate ligament reconstruction (ACLR). It is, however, unclear which specific factors contribute most to these outcomes. PURPOSE To determine associations between demographic characteristics, objective measurements of physical function, patient-reported outcome measure scores, sports-related function assessed with the Knee injury and Osteoarthritis Outcome Score (KOOS) Sport and Recreation subscale, and psychological readiness to RTS assessed with the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale at 1 year after ACLR. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS At a mean of 12.5 ± 2.0 months after ACLR, 143 participants (50.3% female), with a mean age of 25.0 ± 5.7 years, were assessed for demographic characteristics, physical factors (hop performance, muscle strength, ankle and hip range of motion), and psychological factors (KOOS Pain and Symptoms subscales, Perceived Stress Scale, fear of reinjury) as well as the KOOS Sport and Recreation subscale and ACL-RSI scale. Backward linear regression models were used to evaluate factors associated with sports function and psychological readiness to RTS. RESULTS Lower isokinetic knee extension peak torque (limb symmetry index) (B = 18.38 [95% CI, 3.01-33.75]), lower preinjury activity level (B = 2.00 [95% CI, 0.87-3.14]), greater knee pain (B = 0.90 [95% CI, 0.70-1.10]), shorter time between injury and reconstruction (B = 0.16 [95% CI, 0.05-0.26]), and greater fear of reinjury (B = 0.11 [95% CI, 0.01-0.20]) were associated with a worse KOOS Sport and Recreation subscore (R2 = 0.683). A shorter hop distance (B = 0.15 [95% CI, 0.00-0.29]) was associated with a lower ACL-RSI score (R2 = 0.245). CONCLUSION A combination of knee muscle strength, activity level, knee pain, timing of surgery, and fear of reinjury accounted for approximately 70% of the variation in sports function at 1 year after ACLR. In contrast, there was only 1 weak association between physical function and psychological readiness to RTS at this time point. Thus, factors associated with current sports function are much better known than features related to psychological readiness to RTS.

Abstract
AIM To study the association between within-person changes in patient-reported outcomes (PROMs) and wish for joint surgery during participation in a digital first-line intervention comprising exercise and education for knee/hip osteoarthritis (OA). METHODS Retrospective observational registry study. Participants enrolled between June 1, 2018 and October 30, 2021, with follow-up data at three months (n = 13,961). We used asymmetric fixed effect (conditional) logistic regressions to study the association between change in wish to undergo surgery at last available time point (3, 6, 9, or 12 months) and improvement or worsening of PROMs pain (0-10), quality of life (QoL) (EQ5D-5L, 0.243-0.976), overall health (0-10), activity impairment (0-10), walking difficulties (yes/no), fear of movement (yes/no), and Knee/Hip injury and Osteoarthritis Outcome Score 12 Items (KOOS-12/HOOS-12, 0-100) function and QoL subscales. RESULTS The proportion of participants wishing to undergo surgery declined by 2% (95% CI: 1.9, 3.0), from 15.7% at the baseline to 13.3% at 3 months. Generally, improvements in PROMs were associated with reduced likelihood of wishing for surgery, while worsening was associated with increased likelihood. For pain, activity impairment EQ-5D and KOOS/HOOS QoL, a worsening led to a change in the probability of wish for surgery of larger absolute magnitude than an improvement in the same PROM. CONCLUSIONS Within-person improvements in PROMs are associated with reduced wish for surgery while worsenings with an increased wish for surgery. Larger improvements in PROMs may be needed to match the magnitude of the change in wish for surgery associated with a worsening in the same PROM.

Abstract
Objective Establish proportions of patients reporting important improvement, acceptable symptoms and treatment failure and define interpretation threshold values for pain, patient-reported function and quality-of-life after participating in digital first-line treatment including education and exercise for hip and knee osteoarthritis (OA). Methods Observational study. Responses to the pain Numeric Rating Scale (NRS, 0-10 best to worst), Knee injury and Osteoarthritis Outcome Score 12 (KOOS-12) and Hip disability and Osteoarthritis Outcome Score 12 (HOOS-12, both 0-100 worst to best) were obtained for 4383 (2987) and 2041 (1264) participants with knee (hip) OA at 3 and 12 months post intervention. Threshold values for Minimal Important Change (MIC), Patient Acceptable Symptom State (PASS) and Treatment Failure (TF) were estimated using anchor-based predictive modeling. Results 70-85% reported an important improvement in pain, function and quality of life after 3 and 12 months follow-up. 42% (3 months) and 51% (12 months) considered their current state as satisfactory, whereas 2-4% considered treatment failed. MIC values were -1 (NRS) and 0-4 (KOOS/HOOS-12) across follow-ups and joint affected. PASS threshold value for NRS was 3, and 53-73 for the KOOS/HOOS-12 subscales Corresponding values for TF were 5 (NRS) and 34-55 (KOOS/HOOS-12). Patients with more severe pain at baseline had higher MIC scores and accepted poorer outcomes at follow-ups. Conclusion Threshold estimates aid in the interpretation of outcomes after first-line OA interventions assessed with NRS Pain and KOOS/HOOS-12. Baseline pain severity is important to consider when interpreting threshold values after first-line interventions in these patients.

Abstract
BACKGROUND The risk of sustaining a graft rupture after anterior cruciate ligament reconstruction (ACLR) is high. Contributing risk factors are, however, still not clearly identified. OBJECTIVE The aim of this systematic review was to identify and quantify risk factors for graft rupture after ACLR. METHODS A systematic review with meta-analysis (PROSPERO CRD42020140129) based on PRISMA guidelines was performed. MEDLINE, CINAHL and EMBASE were searched from inception to September 2021. Prospective and retrospective studies addressing risk factors for graft rupture after ACLR in males/females of all ages were considered. Meta-analyses using a random effect model (effect measure: odds ratio [OR] with 95% confidence interval [CI]) were performed. The GRADE tool was used to assess evidence quality. RESULTS Following full-text screening of 310 relevant papers, 117 were eventually included, incorporating up to 133,000 individuals in each meta-analysis. Higher Tegner activity level (≥ 7 vs < 7) at primary injury (OR 3.91, 95% CI 1.69-9.04), increased tibial slope (degrees) (OR 2.21, 95% CI 1.26-3.86), lower psychological readiness to return to sport (RTS) (OR 2.18, 95% CI 1.32-3.61), early surgery (< 12 vs ≥ 12 months) (OR 1.87, 95% CI 1.58-2.22), RTS (pre-injury level) (OR 1.87, 95% CI 1.21-2.91) and family history of ACL injury (OR 1.76, 95% CI 1.34-2.31) were all associated with increased odds of graft rupture. Higher age (OR 0.47, 95% CI 0.39-0.59), female sex (OR 0.88, 95% CI 0.79-0.98), fewer self-reported knee symptoms pre-reconstruction (OR 0.81, 95% CI 0.69-0.95) and concomitant cartilage injuries (OR 0.70, 95% CI 0.62-0.79) instead decreased the odds. Meta-analysis revealed no association between body mass index, smoking, joint laxity, RTS time, knee kinematics, muscle strength or hop performance and graft rupture. CONCLUSION Conspicuous risk factors for graft rupture were mainly sports and hereditary related. Few studies investigated function-related modifiable factors or included sports exposure data.

Abstract
Background Two commonly used instruments to assess muscle strength after anterior cruciate ligament reconstruction are the isokinetic dynamometer, which measures isokinetic torque and the hand-held dynamometer, which measures isometric torque. Isokinetic dynamometers are considered superior to other instruments but may not be commonly used in clinical settings. Hand-held dynamometers are small, portable, and more clinically applicable devices. Purpose The purpose of this study was to assess agreement between a hand-held dynamometer and an isokinetic dynamometer, used to assess lower limb symmetry in knee muscle torque one year after anterior cruciate ligament (ACL) reconstruction. Study design Cross-sectional measurement study. Methods Seventy-two participants who had undergone ACL reconstruction (35 men, 37 women; age= 25.8 ± 5.4 years) were included. Isokinetic muscle torque in knee flexion and extension was measured with an isokinetic dynamometer. Isometric flexion and extension knee muscle torque was measured with a hand-held dynamometer. Bland & Altman plots and Cohen's Kappa coefficient were used to assess agreement between measurements obtained from the instruments. Result Bland & Altman plots showed wide limits of agreement between the instruments for both flexion and extension limb symmetry index. Cohen´s Kappa coefficient revealed a poor to slight agreement between the extension limb symmetry index values (0.136) and a fair agreement for flexion limb symmetry index values (0.236). Cross-tabulations showed that the hand-held dynamometer detected a significantly larger number of participants with abnormal flexion torque limb symmetry index compared to the isokinetic dynamometer. Conclusion The wide limits of agreements and Cohen's Kappa coefficients values revealed insufficient agreement between the measurements taken with the two instruments, indicating that the instruments should not be used interchangeably. The hand-held dynamometer was more sensitive in detecting abnormal limb symmetry index in flexion torque, which promotes the option of use of hand-held dynamometers to detect differences between the injured and uninjured leg after ACL reconstruction. Level of evidence 3b.

Abstract
IMPORTANCE Digital care platforms have been introduced, but there is limited evidence for their efficacy compared with traditional face-to-face treatment modalities. OBJECTIVE To compare mean pain reduction among individuals with osteoarthritis (OA) of the knee or hip who underwent face-to-face vs digital first-line intervention. DESIGN, SETTING, AND PARTICIPANTS This registry-based cohort study included all persons with knee or hip osteoarthritis who participated in structured first-line treatment for osteoarthritis in a primary care setting in Sweden. Inclusion criteria were as follows: the treatment was delivered face-to-face or digitally between April 1, 2018, and December 31, 2019; patients provided 3-month follow-up data for pain; and patients had program adherence of at least 80%. Data analysis was conducted in March 2021. EXPOSURES Participants completed a 3-month intervention, including education and exercise for hip or knee osteoarthritis, with program adherence of 80% or higher, delivered face-to-face or by a digital application. MAIN OUTCOMES AND MEASURES Difference in change in joint pain (11-point numeric rating scale, with 0 indicating no pain and 10, the worst possible pain) between baseline and 3-month follow-up between the 2 intervention modalities. A minimal clinically important difference in pain change between groups was predefined as 1 point. Secondary outcomes were walking difficulties, health-related quality of life, willingness to undergo joint surgery, and fear avoidance behavior. RESULTS A total of 6946 participants (mean [SD] age, 67 [9] years; 4952 [71%] women; 4424 [64%] knee OA; 2504 [36%] hip OA) were included, with 4237 (61%) receiving face-to-face treatment and 2709 (39%) receiving digital treatment. Both the face-to-face (mean change, -1.10 [95% CI -1.17 to -1.02] points) and digital interventions (mean change, -1.87 [95% CI, -1.94 to -1.79] points) resulted in a clinically important pain reduction at 3 months. Participants in the digitally delivered intervention experienced a larger estimated improvement at 3 months (adjusted mean difference, -0.93 [95% CI, -1.04 to -0.81] points). Results of secondary outcomes were broadly consistent with main outcome. CONCLUSIONS AND RELEVANCE This Swedish national registry-based cohort study showed that people with knee or hip OA participating in first-line intervention experienced clinically relevant improvements in pain, whether delivered face-to-face or digitally. The increased benefit of digital delivery compared with face-to-face delivery was of uncertain clinical importance.

Abstract
Osteoarthritis (OA) is a highly prevalent group of disorders and among the most common causes of chronic pain and disability globally. First-line evidence-based treatments for hip and knee OA, two of the most common variants, are available in Sweden with the potential for wide national reach through face-to-face and digital platforms. Research results suggest important reductions in symptoms in patients with knee or hip OA. Despite evidence, availability and low cost, first-line evidence-based treatments are not utilized to the full extent to reduce the burden of OA.

Abstract
OBJECTIVE To assess the proportion of participants reconsidering their willingness to undergo surgery after 3 and 12 months. Secondary aims were to analyze and compare the characteristics of individuals willing and unwilling to undergo joint surgery for osteoarthritis (OA) before a first-line intervention, and to study the association between pain intensity, walking difficulties, self-efficacy, and fear of movement with the willingness to undergo surgery. METHODS This was an observational study based on Swedish register data. We included 30,578 individuals with knee or hip OA who participated in a first-line intervention including education and exercise. RESULTS Individuals willing to undergo surgery at baseline showed a higher proportion of men (40% versus 27%) and more severe symptoms and disability. Respectively, 45% and 30% of the individuals with knee and hip OA who were willing to undergo surgery at baseline became unwilling after the intervention. At the end of the study period (12 months), 35% and 19% of those with knee and hip OA, respectively, who were willing to undergo surgery at baseline became unwilling. High pain intensity, walking difficulties, and fear of movement were associated with higher odds of being willing to undergo surgery at both follow-ups, while increased self-efficacy showed the opposite association. CONCLUSION A first-line intervention for OA is associated with reduced willingness to undergo surgery, with a greater proportion among patients with knee OA than hip OA. Due to its temporal variability, willingness to undergo surgery should be used with care to deem surgery eligibility.

Abstract
Objectives There is limited research on sex differences in postural orientation (ie, alignment between body segments) in people with knee injury measured with a clinically applicable method. An understanding of the relationship between postural orientation and physical function may help guide decision making in rehabilitation. The aims were to evaluate (1) sex differences in visual assessment of Postural Orientation Errors (POEs) and (2) the association between POEs and objective and patient-reported physical function, in men and women with anterior cruciate ligament reconstruction (ACLR). Methods Twenty-four women and 29 men (mean 26.7 (SD 6.5) years) with ACLR were included. Six POEs (lower extremity and trunk) were scored from a video of five tasks with varying difficulty to compute POE scores (total and subscores). Objective physical function was evaluated with the single-leg hop for distance and side hop. Patient-reported physical function was evaluated using patient-reported outcome measures (PROMs). Results Women had significantly more POEs than men (median difference 5.5–25, p≤0.028). More POEs were associated with shorter hop distance and fewer side hops in women (rs= −0.425 to −0.518, p<0.038), but not in men (rs<0.301, p>0.05). No associations were found between POE scores and PROMs, in either sex (rs< –0.246, p>0.05). Conclusions Women with ACLR seem to have more POEs compared with men, indicating worse postural orientation. More POEs were associated with worse hop performance, suggesting that POE scores may be used as criteria for rehabilitation progression. The lack of associations between POE scores and PROMs indicate that these measures complement each other.

Abstract
INTRODUCTION People with anterior cruciate ligament (ACL) reconstruction (ACLR) are at high risk of sustaining a graft rupture and/or contra-lateral ACL injury. The main factors that may predispose individuals for subsequent ACL injuries are, however, not established. To reduce the risk of reinjuries, it is of particular interest to identify modifiable risk-factors, for instance, those related to sensorimotor control which are responsive to training. The aim of the current study protocol is to present the design of our prospective cohort study STOP Graft Rupture investigating sensorimotor function as predictors for graft rupture, contra-lateral ACL injury and/or failure to return to sport (RTS) within 3 years following ACLR. METHODS AND ANALYSIS We aim to recruit 200 individuals (15-35 years, ~50% women) with ACLR from Norrland University Hospital, Umeå and Lund University Hospital, Lund, Sweden. Participants will be assessed with a comprehensive test battery for sensorimotor muscle function, including hop performance, muscle strength, muscle activation, hip and ankle range of motion and postural orientation as well as patient-reported function 1 year after ACLR (baseline). For a subgroup of individuals (Umeå cohort), 3D kinematics and joint position sense will also be evaluated. At follow-up (≥3 years post-ACLR), the participants will be asked to answer questions related to new ACL injuries to either knee and about RTS. Separate logistic regression models, adjusting for possible confounders, will be used to evaluate the influence of the different sensorimotor predictors on the prospective outcomes (graft rupture, contra-lateral ACL injury, RTS). ETHICS AND DISSEMINATION This study was approved by the Swedish Ethical Review Board (Dnr 2016/319 and Dnr 2019-04037). The results will be published in international peer-reviewed scientific journals and presented at clinical and scientific congresses. TRIAL REGISTRATION NUMBER NCT04162613.

Abstract
BACKGROUND To systematically review the association between knee abduction kinematics and kinetics during weight-bearing activities at baseline and the risk of future anterior cruciate ligament (ACL) injury. METHODS Systematic review and meta-analysis according to PRISMA guidelines. A search in the databases MEDLINE (PubMed), CINAHL, EMBASE and Scopus was performed. Inclusion criteria were prospective studies including people of any age, assessing baseline knee abduction kinematics and/or kinetics during any weight-bearing activity for the lower extremity in individuals sustaining a future ACL injury and in those who did not. RESULTS Nine articles were included in this review. Neither 3D knee abduction angle at initial contact (Mean diff: -1.68, 95%CI: - 4.49 to 1.14, ACL injury n = 66, controls n = 1369), peak 3D knee abduction angle (Mean diff: -2.17, 95%CI: - 7.22 to 2.89, ACL injury n = 25, controls n = 563), 2D peak knee abduction angle (Mean diff: -3.25, 95%CI: - 9.86 to 3.36, ACL injury n = 8, controls n = 302), 2D medial knee displacement (cm; Mean diff:: -0.19, 95%CI: - 0,96 to 0.38, ACL injury n = 72, controls n = 967) or peak knee abduction moment (Mean diff:-10.61, 95%CI: - 26.73 to 5.50, ACL injury n = 54, controls n = 1330) predicted future ACL injury. CONCLUSION Contrary to clinical opinion, our findings indicate that knee abduction kinematics and kinetics during weight-bearing activities may not be risk factors for future ACL injury. Knee abduction of greater magnitude than that observed in the included studies as well as factors other than knee abduction angle or moment, as possible screening measures for knee injury risk should be evaluated in future studies.

Abstract
Objective To examine patient willingness and a possible shift in willingness for surgery and to investigate factors associated with this shift, following participation in the digital nonsurgical osteoarthritis (OA) treatment program Joint Academy. Methods A total of 458 individuals (mean ± SD age 62 ± 5.6 years, 67% women) with diagnosed hip or knee OA were evaluated after 6 weeks in the Joint Academy program, comprising education and exercise as well as asynchronous chat with a physical therapist. Data describing joint pain, health‐related quality of life (the EuroQol 5‐domain [EQ‐5D] questionnaire in 3 levels), walking difficulties, the 30‐second chair stand test, and willingness to consider surgery were collected at baseline and at 6 weeks. Results At follow‐up, 31% of those participants willing to consider surgery at baseline no longer considered surgery. Of those participants who were unwilling to consider surgery at baseline, 6% reconsidered and decided in favor of surgery at follow‐up. Less pain and a higher EQ‐5D score at 6 weeks were associated with the change from being willing to unwilling to consider surgery at follow‐up (odds ratio [OR] 0.67–1.64; P < 0.05). Worse pain, a lower EQ‐5D score, and having walking difficulties at 6 weeks, and a lower pain and EQ‐5D score improvement were associated with the change from being unwilling to willing to consider surgery at 6 weeks (OR 0.51–4.30; P < 0.005). Conclusion Evidence‐based nonsurgical OA treatment, at least delivered in a digital format, may reduce the need for surgery and should therefore be offered as the first‐line treatment option to patients with hip and knee OA. The results also support the idea that such treatment programs have the potential to improve selection of patients for total joint replacement.

Abstract
OBJECTIVE To explore, using a qualitative approach, reasons for patients' continued willingness or their shift in willingness for total joint replacement (TJR) surgery, following participation in Joint Academy, a Swedish, digital, non-surgical treatment program for osteoarthritis (OA). DESIGN Nineteen patients with hip or knee OA were interviewed after finishing their first 6 weeks in the treatment program, using a semi-structured interview guide. The interviews were transcribed verbatim and analyzed using a systematic text condensation method. RESULTS Analysis of the interview data revealed three main categories of reasons provided for the participants' decisions regarding surgery: 1) Various reasons for participating in Joint Academy with three sub-categories: (a) longstanding pain affects daily life, (b) last chance for improvement and (c) mandatory treatment to be eligible for total joint replacements (TJR); 2) Willingness for TJR following treatment, which included four sub-categories: (a) surgery - the last resort, (b) reduced pain and improved functioning, (c) no perceived improvements after treatment, and (d) trust in healthcare providers; and 3) Expectations of TJR. The shift in willingness towards or away from TJR was mainly due to the perceived success of Joint Academy in improving their functioning. CONCLUSION Several patients reconsidered their options and had changed their attitude to TJR after participation in a digital program aimed at reducing OA symptoms and improving functioning. These results highlight the importance of providing patients with adequate information about non-surgical management options to facilitate shared decision-making, and possibly reduce the need for surgery.

Abstract
OBJECTIVES To investigate the experiences of a digital management programme for hip and knee osteoarthritis (OA), including education and exercises as well as an option to chat with an assigned physical therapist for feedback, questions and support. SETTING This study was conducted at a regional hospital in the southern part of Sweden. METHODS Nineteen patients (10 women), median age of 66 (q1-q3, 57-71) years, with confirmed hip or knee OA were interviewed after completing their first 6 weeks in the programme, using a semistructured interview guide. The interviews were transcribed verbatim and were qualitatively analysed using systematic text condensation. RESULTS Three categories emerged during the interviews:(1) Management options for mitigating the consequences of OA; (2) Experiences of the digital programme and (3) Perceived effects of the digital programme over time. The participants had mostly positive experiences of the programme. Particularly important for these experiences were no waiting list, the flexibility of taking part in the programme with regards to location and time and the possibility to have daily contact with a physical therapist. These aspects were also emphasised as advantages compared with traditional care. CONCLUSIONS Digital management of OA, including education and exercise, was experienced as a valid alternative to traditional treatment in enabling the implementation of OA guidelines in a wider community. Easy access, exercising at one's own convenience, flexible options, daily follow-up and support by a physical therapist were mentioned as the most important features. In addition, the results will contribute to further development and improvement of digital OA management programmes.

Abstract
OBJECTIVE To investigate if muscle strength and muscle activation patterns are associated with increased knee abduction during two functional tasks, commonly used in rehabilitation for individuals with anterior cruciate ligament reconstruction (ACLR). DESIGN Cross-sectional study. SETTING Laboratory. PARTICIPANTS 24 women and 29 men approximately 7 months after ACLR. MAIN OUTCOME MEASURES Isometric peak torque of the trunk and lower extremity muscles were determined during maximal voluntary contractions. Trunk and lower extremity average muscle activation amplitude and peak knee abduction were evaluated during the single-leg squat (SLS) and the single-leg hop for distance (SLHD) for the injured side. Separate backward regressions were performed for men and women. RESULTS In women, lower knee flexion and extension strength were associated with greater peak knee abduction during the SLS (B = 4.63-18.26, p ≤ 0.036); lower knee flexion strength and iliocostalis activation on the non-injured side were associated with greater peak knee abduction during the SLHD (B = 0.60-20.48, p ≤ 0.043). No associations between muscle function and peak knee abduction were found in men. CONCLUSIONS Muscle function may contribute differently to knee abduction in men and women after ACLR. This should be considered when designing rehabilitation programs to reduce knee abduction in these patients.

Abstract
[Purpose] To investigate the association between proprioception and a knee medial to
foot position during weight-bearing activities in patients with anterior cruciate ligament
reconstruction and anterior cruciate ligament deficiency. [Participants and Methods]
Thirty-eight patients with anterior cruciate ligament reconstruction and 13 patients with
anterior cruciate ligament deficiency aged 18–40 years were included. Proprioception was
assessed by knee kinesthesia measured by the threshold to detection of passive motion.
Movement quality was assessed by visual observation of the position of the knee in
relation to the foot during the mini squat, the single-leg hop for distance, and the
cross-over hop for distance. [Results] In patients with anterior cruciate ligament
deficiency, worse kinesthesia was significantly associated with a knee medial to foot
position during the single-leg hop for distance. No statistically significant associations
were observed between kinesthesia and a knee medial to foot position during the three
tasks in patients with anterior cruciate ligament reconstruction. [Conclusion] Poor
proprioception may be associated with worse movement quality of the knee in patients with
anterior cruciate ligament deficiency, but not in patients with anterior cruciate ligament
reconstruction. Differences in sensorimotor function between patients with reconstructed
and non-reconstructed anterior cruciate ligament should be considered in training and
rehabilitation regimens aiming to enhance performance and prevent further injuries in
these patients.

Abstract
Background Different test procedures are often used within performance-based measures, causing uncertainty as to whether results can be compared between studies. Thus, the aim of this study was to assess agreement between different test procedures for the single-leg hop for distance (SLHD) and the single-leg mini squat (SLMS), respectively, two commonly used tasks for assessing deficiency in lower extremity muscle function. Methods Twenty-three participants (20–42 years) with lower extremity injury performed the SLHD with arms free and with arms behind back, and the Limb Symmetry Index (LSI; injured leg divided by uninjured and multiplied by 100) was calculated. Another group of 28 participants (mean 18–38 years) performed five SLMSs at a pre-defined speed and maximum number of SLMSs during 30 seconds, and were visually observed and scored as either having a knee-over-foot or a knee-medial-to-foot position (KMFP). Results No systematic difference between test procedures for the LSI of the SLHD was noted (p=0.736), Cohen’s kappa = 0.42. The Bland & Altman plot showed wide limits of agreement between test procedures, with particularly poor agreement for participants with abnormal LSI (<90%). Ten participants were scored as having a KMFP during five SLMSs at a predefined speed, while five had a KMFP during maximum number of SLMSs during 30 seconds (p=0.063, Cohen’s kappa = 0.56). Conclusions The moderate agreement between the two test procedures for the SLHD and the SLMS, respectively, indicate that results from these different test procedures should not be compared across studies. SLHD with arms behind back, and five SLMSs at a pre-defined speed, respectively, were the most sensitive procedures to detect individuals with poor functional performance.

Abstract
BACKGROUND Increased knee abduction angle during activity is suggested to be a risk factor for sustaining an anterior cruciate ligament (ACL) injury or developing patellofemoral pain syndrome (PFPS). Knowledge of the modifiable mechanisms that are associated with increased knee abduction will aid in the appropriate design of preventive and rehabilitative strategies for these injuries. OBJECTIVE Our objective was to systematically review modifiable mechanisms contributing to increased knee abduction in healthy people and in individuals with an ACL injury or PFPS. METHODS We performed a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched the databases MEDLINE, CINAHL, and Embase until September 2015. Inclusion criteria were studies in healthy individuals and/or those with ACL injury or PFPS reporting (1) muscle strength, muscle activation, proprioception, and/or range of motion (ROM) and (2) knee abduction angle assessed with either motion analysis or visual observation during weight-bearing activity. RESULTS In total, 33 articles were included. Reduced trunk strength, reduced gluteus maximus amplitude, decreased ankle ROM, and increased hip external rotation ROM were moderately associated with increased knee abduction angle (r -0.34 or higher, standardized difference in means (SDM) greater than -0.39, p < 0.05, articles n = 3, total sample size n = 101-114) in healthy individuals. Decreased strength of hip abductors, external rotators, and extensors and knee flexors were at most weakly associated with increased knee abduction angle (r ≤ 0.21, p = 0.013-0.426, articles n = 2-9, total sample size n = 80-311). Too few articles included patients with knee injury to be included in any meta-analysis. CONCLUSION The associations identified in this review indicate that investigation of strengthening of the trunk muscles, and improvement of gluteus maximus activation and ankle ROM to change knee kinematics is merited. Studies on modifiable factors associated with increased knee abduction angle in people with knee injury are needed.

Abstract
OBJECTIVES To systematically review measurement properties of visual assessment and rating of Postural Orientation Errors (POEs) in participants with or without lower extremity musculoskeletal disorders. METHODS A systematic review according to the PRISMA guidelines was conducted. The search was performed in Medline (Pubmed), CINAHL and EMBASE (OVID) databases until August 2016. Studies reporting measurement properties for visual rating of postural orientation during the performance of weight-bearing functional tasks were included. No limits were placed on participant age, sex or whether they had a musculoskeletal disorder affecting the lower extremity. RESULTS Twenty-eight articles were included, 5 of which included populations with a musculoskeletal disorder. Visual rating of the knee-medial-to-foot position (KMFP) was reliable within and between raters, and meta-analyses showed that this POE was valid against 2D and 3D kinematics in asymptomatic populations. Other segment-specific POEs showed either poor to moderate reliability or there were too few studies to permit synthesis. Intra-rater reliability was at least moderate for POEs within a task whereas inter-rater reliability was at most moderate. CONCLUSIONS Visual rating of KMFP appears to be valid and reliable in asymptomatic adult populations. Measurement properties remain to be determined for POEs other than KMPF.

Abstract
Background In patients with anterior cruciate ligament (ACL) deficiency (ACLD) or reconstruction (ACLR), sensory deficits are commonly assessed as knee kinesthesia using time-consuming laboratory equipment. Portable equipment such as that used for evaluation of vibration sense would be preferable. In contrast to kinesthesia, vibration sense is not well studied in these patients. Objectives 1) To study the association between kinesthesia and vibration sense to investigate if one sensory measurement can replace the other; and 2) to determine the clinical relevance by investigating associations between the sensory measurements and functional performance and patient-reported outcomes in patients with ACLD or ACLR. Methods Twenty patients with ACLD and 33 patients with ACLR were assessed with knee kinesthesia, vibration sense, the one-leg hop test for distance, as well as the Knee injury and Osteoarthritis Outcome Score (KOOS) and the Tegner Activity Scale. Results There were no significant correlations between kinesthesia and vibration sense (r= −0.267, p>0.269) or between the sensory measures and hop performance (r= −0.351, p>0.199). In patients with ACLD, worse knee kinesthesia was associated with worse scores on KOOS subscales pain (r= −0.464, p=0.046) and activities of daily living (r= −0.491, p=0.033), and worse vibration sense was associated with worse scores on KOOS subscale quality of life (r= −0.469, p=0.037) and worse knee confidence (item Q3 from subscale quality of life) (rs=0.436, p=0.054). In patients with ACLR, worse vibration sense was associated with worse scores on KOOS subscales pain (r= −0.402, p=0.020) and activities of daily living (r= −0.385, p=0.027). Conclusion Kinesthesia and vibration sense cannot be used interchangeably as measures of sensory function in patients with ACLD or ACLR. Both sensory measurements were weakly related to hop performance. Adequate sensory function appears to have importance for perceived function in patients with ACLD or ACLR and may therefore be a factor that needs to be addressed in rehabilitation programs for these patients.

Abstract
BACKGROUND Increased knee abduction during weight-bearing activities is suggested to be a contributing factor for the high knee injury risk reported in women. However, studies investigating gender difference in knee abduction are inconclusive. OBJECTIVE To systematically review gender-differences in knee abduction during weight-bearing activities in individuals with or without knee injury. METHODS A systematic review and meta-analysis were conducted according to the PRISMA guidelines. A search in the databases Medline, CINAHL and EMBASE was performed until September 2015. Inclusion criteria were studies that reported (1) gender differences, (2) healthy individuals and/or those with anterior cruciate ligament (ACL) deficiency or reconstruction or patellofemoral pain PFP, and (3) knee abduction assessed with either motion analysis or visual observation during weight-bearing activity. RESULTS Fifty-eight articles met the inclusion criteria. Women with PFP had greater peak knee abduction compared to men (Std diff in mean; -1.34, 95%CI; -1.83 to -0.84). In healthy individuals, women performed weight-bearing tasks with greater knee abduction throughout the movement (initial contact, peak abduction, excursion) (Std diff in mean; -0.68 to -0.79, 95%CI; -1.04 to -0.37). In subgroup analyses by task, differences in knee abduction between genders were present for most tasks, including running, jump landings and cutting movements. There were too few studies in individuals with ACL injury to perform meta-analysis. CONCLUSION The gender difference in knee abduction during weight-bearing activities should be considered in training programs aimed at preventing or treating knee injury.

Abstract
BACKGROUND Patients with anterior cruciate ligament (ACL) injury often exhibit reduced movement quality during functional tasks in the form of a knee-medial-to-foot position (KMFP). This movement pattern is suggested to be more common in women than in men, but the possible contributing sensorimotor factors for this altered knee position are poorly studied in these patients. The aim of this study was to evaluate the association between sensory function and medio-lateral knee position during functional tasks in men and women with ACL injury. METHODS Fifty-one patients (23 women) aged 18-40 years with ACL injury were included in this cross-sectional study. Measures of sensory function were assessed by the threshold to detection of passive motion (TDPM) for knee kinesthesia and by the vibration perception threshold (VPT) for vibration sense. Movement quality was assessed by visual observation of the position of the knee relative to the foot during the following four functional tasks with different degrees of difficulty: the single-limb mini-squat, stair descending, the forward lunge, and the drop-jump. Spearman's rank correlation coefficient was used to determine the relationship between the sensory measures and the medio-lateral knee position during the functional tasks. Differences in TDPM and/or VPT between subjects with good and poor movement quality were evaluated using the independent t-test. Separate gender analyses were performed. RESULTS Worse TDPM was associated with a KMFP during the drop jump in men. Worse VPT at the toe and ankle was associated with a KMFP during stair descending and the forward lunge in women, but no associations were found in men. CONCLUSION Worse kinesthesia, measured by TDPM, might be associated with KMFP during the drop jump in men with ACL injury while worse vibration sense, measured by the VPT, at the foot and ankle might be related to KMFP in women. Further studies are needed to confirm these results.
