Psychological Factors Change During the Rehabilitation of an Achilles Tendon Rupture: A Multicenter Prospective Cohort Study.

OBJECTIVE: The authors sought to gain insight into the changes in psychological factors during rehabilitation after Achilles tendon rupture (ATR) and to explore the association between psychological factors during rehabilitation and functional outcome 12 months after ATR. METHODS: Fifty patients clinically diagnosed with ATR were invited to visit the hospital 3, 6, and 12 months after injury for data collection. They completed questionnaires assessing psychological factors: psychological readiness to return to sport (Injury Psychological Readiness to Return to Sport Questionnaire); kinesiophobia (Tampa Scale for Kinesiophobia); expectations, motivation, and outcome measures related to symptoms and physical activity (Achilles Tendon Total Rupture Score); and sports participation and performance (Oslo Sports Trauma Research Centre Overuse Injury Questionnaire). To determine whether psychological factors changed over time, generalized estimating equation analyses were performed. Multivariate regression analyses were used to study the association between psychological factors at 3, 6, and 12 months and outcome measures at 12 months after ATR. RESULTS: Psychological readiness to return to sport improved, and kinesiophobia decreased significantly during rehabilitation. Psychological readiness at 6 and 12 months showed significant associations with sports participation and performance. Kinesiophobia at 6 months was significantly associated with symptoms and physical activity. Motivation remained high during rehabilitation and was highly associated with symptoms and physical activity, sports participation, and performance. CONCLUSION: Psychological factors change during rehabilitation after ATR. Patients with lower motivation levels during rehabilitation, low psychological readiness to return to sports, and/or high levels of kinesiophobia at 6 months after ATR need to be identified. IMPACT: According to these results, psychological factors can affect the rehabilitation of patients with ATR. Physical therapists can play an important role in recognizing patients with low motivation levels and low psychological readiness for return to sport and patients with high levels of kinesiophobia at 6 months post-ATR. Physical therapist interventions to enhance motivation and psychological readiness to return to sport and to reduce kinesiophobia need to be developed and studied in the post-ATR population. LAY SUMMARY: With Achilles tendon rupture, level of motivation, psychological readiness for return to sport, and fear of movement can affect rehabilitation outcome. A physical therapist can help recognize these factors.

Platelet rich plasma injection for acute Achilles tendon rupture: PATH-2 randomised, placebo controlled, superiority trial.

OBJECTIVE: To determine whether an injection of platelet rich plasma improves outcomes after acute Achilles tendon rupture. DESIGN: Randomised, placebo controlled, two arm, parallel group, participant and assessor masked, superiority trial. SETTING: Secondary care trauma units across 19 hospitals in the United Kingdom's health service. PARTICIPANTS: Recruitment commenced in July 2015 and follow-up was completed in March 2018. 230 adults aged 18 years and over were included, with acute Achilles tendon rupture presenting within 12 days of injury and managed with non-surgical treatment. Exclusions were injury at the insertion or musculotendinous junction, major leg injury or deformity, diabetes mellitus, platelet or haematological disorder, systemic corticosteroids, anticoagulation treatment, and other contraindicating conditions. INTERVENTIONS: Participants were randomised 1:1 to platelet rich plasma (n=114) or placebo (dry needle; n=116) injection. All participants received standard rehabilitation care (ankle immobilisation followed by physiotherapy). MAIN OUTCOMES AND MEASURES: Primary outcome was muscle tendon function at 24 weeks, measured objectively with the limb symmetry index (injured/uninjured×100) in maximal work done during the heel rise endurance test (an instrumented measure of repeated single leg heel rises until fatigue). Secondary outcomes included patient reported function (Achilles tendon rupture score), quality of life (short form 12 version 2®), pain (visual analogue scale), goal attainment (patient specific functional scale), and adverse events. A central laboratory analysed the quality and content of platelet rich plasma. Analyses were by modified intention to treat. RESULTS: Participants were 46 years old on average, and 57 (25%) of 230 were female. At 24 weeks, 202 (88%) participants completed the heel rise endurance test and 216 (94%) the patient reported outcomes. The platelet rich plasma was of good quality, with expected growth factor content. No difference was detected in muscle tendon function between participants receiving platelet rich plasma injections and those receiving placebo injections (limb symmetry index, mean 34.7% (standard deviation 17.7%) v 38.5% (22.8%); adjusted mean difference -3.9% (95% confidence interval -10.5% to 2.7%)) or in any secondary outcomes or adverse event rates. Complier average causal effect analyses gave similar findings. CONCLUSIONS: There is no evidence to indicate that injections of platelet rich plasma can improve objective muscle tendon function, patient reported function, or quality of life after acute Achilles tendon rupture compared with placebo, or that they offer any patient benefit.

Cast versus functional brace in the rehabilitation of patients with a rupture of the Achilles tendon: statistical analysis plan for the UK study of tendo Achilles rehabilitation (UK STAR) multi-centre randomised controlled trial.

BACKGROUND: The incidence of Achilles tendon rupture in the UK is increasing and the best rehabilitation strategy for patients treated non-operatively remains unclear. We describe a statistical analysis plan (SAP) for the UK study of tendo Achilles rehabilitation (UK STAR) multi-centre randomised trial. METHODS/DESIGN: UK STAR is a 1:1, multi-centre, parallel, two-arm, superiority randomised controlled trial. This study aims to evaluate the use of functional bracing compared to plaster cast for the management of acute Achilles tendon rupture in adult patients treated non-operatively. The primary outcome is the Achilles Tendon Rupture Score measured at 9 months after injury and will be estimated based on a linear mixed effects regression model adjusted for the stratification factor (centre) and other key prognostic variables. Secondary outcomes include complications, quality of life and resource use evaluated at 8 weeks and at 3, 6 and 9 months after the injury. Missing data will be summarised and reported by treatment arm. Full details of the planned analysis methods are described in this paper. Further study design details are published in the UK STAR protocol. DISCUSSION: The planned statistical analyses for UK STAR aim to reduce the risk of outcome reporting bias arising from prior data knowledge. Any changes or deviations from the current SAP will be described and justified in the final study report.

Reattachment of the superior peroneal retinaculum versus the bone block procedure for the treatment of recurrent peroneal tendon dislocation: two safe and effective techniques.

PURPOSE: Clinical outcomes between reattachment of the superior peroneal retinaculum (SPR) and the bone block procedure were compared in this study to elucidate which procedure was safer and more effective. METHODS: From 2012 to 2016, 25 patients with recurrent peroneal tendon dislocation underwent the bone block procedure (group A), and another 22 patients underwent reattachment of the SPR (group B). American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Ankle Activity Score (AAS), time to return to sports activity, rate of return to sports level, range of motion (ROM) of the ankle, rate of recurrence, and overall patient satisfaction were collected to evaluate outcomes between the two groups. RESULTS: In group A, 24 patients followed up at a mean period of 42.5 ± 16.7 months. The mean postoperative AOFAS score was 92.9 ± 3.9. The median time to return to sports activity was 6.0 months (IQR 4.3-6.0 months) with 19 patients (79.2%) returning to their previous sports level. Two patients experienced recurrent dislocation, and 22 patients (91.7%) were satisfied with the procedure. In group B, 20 patients followed up at a mean period of 35.8 ± 15.3 months. The mean postoperative AOFAS score was 95.0 ± 4.2. The median time to return to sports activity was 5.0 months (IQR 4.0-5.0 months) with 18 patients (90.0%) returning to their previous sports level. No recurrence was reported, and 18 patients (90.0%) were satisfied with the procedure. The time to return to sports activity in group B was significantly shorter than that in group A. There was no significant difference in complications or clinical outcomes between the two procedures. CONCLUSION: Both procedures offered satisfactory results for recurrent peroneal tendon dislocation with low rates of recurrence and complications. However, the time to return to sports activity after the reattachment of the SPR was shorter than that after the bone block procedure. LEVEL OF EVIDENCE: Retrospective Comparative Study, Level III.

Validity and reliability of the Norwegian translation of the Achilles tendon Total Rupture Score.

PURPOSE: Patient reported outcome measures (PROMs) are increasingly being used in clinical research. The Achilles tendon Total Rupture Score (ATRS) is a PROM designed to assess outcomes in patients with ruptures of the Achilles tendon. The aim of this study was to develop a Norwegian adaption of the ATRS and evaluate its validity and reliability. METHODS: The ATRS was translated into Norwegian in accordance with recommended guidelines. The study included 94 patients treated for Achilles tendon ruptures from January 2010 until February 2013, and the web-based questionnaires were administered twice. Reliability was assessed by Cronbach's alpha, the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). Construct validity was evaluated by calculating the Spearman's correlation coefficient with the five subclasses of the Foot and Ankle Outcome Score (FAOS), the SF-36 subclass physical function and the SF-36 physical and mental summary scores. RESULTS: Both internal consistency (Cronbach's alpha = 0.96) and test-retest reliability (ICC = 0.90) were excellent, and the MDC was 2.12 at the group level and 16.98 at the individual level. Construct validity was supported by Spearman's correlation coefficients above 0.7 with the SF-36 subclass physical function and the SF-36 physical summary score as well as the FAOS subclasses Sport/Rec and quality of life. There was no floor effect, and 6 patients (6.4%) achieved a maximum score of 100. CONCLUSIONS: The Norwegian adaption of the ATRS demonstrates acceptable validity and reliability for use in the Norwegian population to assess clinical outcomes in patients with Achilles tendon ruptures.

The chinese version of achilles tendon total rupture score: cross-cultural adaptation, reliability and validity.

BACKGROUND: The Achilles tendon Total Rupture Score (ATRS), which is originally developed in 2007 in Swedish, is the only patient-reported outcome measure (PROM) for specific outcome assessment of an Achilles tendon rupture.Purpose of this study is to translate and cross-culturally adapt Achilles tendon Total Rupture Score (ATRS) into simplified Chinese, and primarily evaluate the responsiveness, reliability and validity. METHODS: International recognized guideline which was designed by Beaton was followed to make the translation of ATRS from English into simplified Chinese version (CH-ATRS). A prospective cohort study was carried out for the cross-cultural adaptation. There were 112 participants included into the study. Psychometric properties including floor and ceiling effects, Cronbach's alpha, intraclass correlation coefficient, effect size, standard response mean, and construct validity were tested. RESULTS: The mean scores of CH-ATRS are 57.42 ± 13.70. No sign of floor or ceiling effect was found of CH-ATRS. High level of internal consistency was supported by the value of Cronbach's alpha (0.893). ICC (0.979, 95%CI: 0.984-0.993) was high to indicate the high test-retest reliability. Great responsive ness was proved with the high absolute value of ES and SRM (0.84 and 8.98, respectively). The total CH-ATRS score had very good correlation with physical function and body pain subscales of SF-36 (r = -0.758 and r = -0.694, respectively, p < 0.001), while poor correlation with vitality and role physical subscales of SF-36 (r = -0.033 and r = -0.025, respectively, p ≥ 0.05), which supported construct validity of CH-ATRS. CONCLUSION: This Chinese version of Achilles tendon Total Rupture Score (CH-ATRS) can be used as a reliable and valid instrument for Achilles tendon rupture assessing in Chinese-speaking population.

Mental Health Has a Stronger Association with Patient-Reported Shoulder Pain and Function Than Tear Size in Patients with Full-Thickness Rotator Cuff Tears.

BACKGROUND: Patient-reported outcome measures have increasingly accompanied objective examination findings in the evaluation of orthopaedic interventions. Our objective was to determine whether a validated measure of mental health (Short Form-36 Mental Component Summary [SF-36 MCS]) or measures of tear severity on magnetic resonance imaging were more strongly associated with self-assessed shoulder pain and function in patients with symptomatic full-thickness rotator cuff tears. METHODS: One hundred and sixty-nine patients with full-thickness rotator cuff tears were prospectively enrolled. Patients completed the Short Form-36, visual analog scales for shoulder pain and function, the Simple Shoulder Test (SST), and the American Shoulder and Elbow Surgeons (ASES) instrument at the time of diagnosis. Shoulder magnetic resonance imaging examinations were reviewed to document the number of tendons involved, tear size, tendon retraction, and tear surface area. Age, sex, body mass index, number of medical comorbidities, smoking status, and Workers' Compensation status were recorded. Bivariate correlations and multivariate regression models were calculated to identify associations with baseline shoulder scores. RESULTS: The SF-36 MCS had the strongest correlation with the visual analog scale for shoulder pain (Pearson correlation coefficient, -0.48; p < 0.001), the visual analog scale for shoulder function (Pearson correlation coefficient, -0.33; p < 0.001), the SST (Pearson correlation coefficient, 0.37; p < 0.001), and the ASES score (Pearson correlation coefficient, 0.51; p < 0.001). Tear severity only correlated with the visual analog scale for shoulder function; the Pearson correlation coefficient was 0.19 for tear size (p = 0.018), 0.18 for tendon retraction (p = 0.025), 0.18 for tear area (p = 0.022), and 0.20 for the number of tendons involved (p = 0.011). Tear severity did not correlate with other scores in bivariate correlations (all p > 0.05). In all multivariate models, the SF-36 MCS had the strongest association with the visual analog scale for shoulder pain, the visual analog scale for shoulder function, the SST, and the ASES score (all p < 0.001). CONCLUSIONS: Patient mental health may play an influential role in patient-reported pain and function in patients with full-thickness rotator cuff tears. Further studies are needed to determine its effect on the outcome of the treatment of rotator cuff disease.

One-year Patient-reported Outcomes After Arthroscopic Rotator Cuff Repair Do Not Correlate With Mild to Moderate Psychological Distress.

BACKGROUND: Patients with shoulder and rotator cuff pathology who exhibit greater levels of psychological distress report inferior preoperative self-assessments of pain and function. In several other areas of orthopaedics, higher levels of distress correlate with a higher likelihood of persistent pain and disability after recovery from surgery. To our knowledge, the relationship between psychological distress and outcomes after arthroscopic rotator cuff repair has not been similarly investigated. QUESTIONS/PURPOSES: (1) Are higher levels of preoperative psychological distress associated with differences in outcome scores (visual analog scale [VAS] for pain, Simple Shoulder Test, and American Shoulder and Elbow Surgeons score) 1 year after arthroscopic rotator cuff repair? (2) Are higher levels of preoperative psychological distress associated with less improvement in outcome scores (VAS for pain, Simple Shoulder Test, and American Shoulder and Elbow Surgeons score) 1 year after arthroscopic rotator cuff repair? (3) Does the prevalence of psychological distress in a population with full-thickness rotator cuff tears change when assessed preoperatively and 1 year after arthroscopic rotator cuff repair? METHODS: Eighty-five patients with full-thickness rotator cuff tears were prospectively enrolled; 70 patients (82%) were assessed at 1-year followup. During the study period, the three participating surgeons performed 269 rotator cuff repairs; in large part, the low overall rate of enrollment was related to two surgeons enrolling only two patients total in the initial 14 months of the study. Psychological distress was quantified using the Distress Risk Assessment Method questionnaire, and patients completed self-assessments including the VAS for pain, the Simple Shoulder Test, and the American Shoulder and Elbow Surgeons score preoperatively and 1 year after arthroscopic rotator cuff repair. Fifty of 85 patients (59%) had normal levels of distress, 26 of 85 (31%) had moderate levels of distress, and nine of 85 (11%) had severe levels of distress. Statistical models were used to assess the effect of psychological distress on patient self-assessment of shoulder pain and function at 1 year after surgery. RESULTS: With the numbers available, distressed patients were not different from nondistressed patients in terms of postoperative VAS for pain (1.9 [95% confidence interval {CI}, 1.0-2.8] versus 1.0 [95% CI, 0.5-1.4], p = 0.10), Simple Shoulder Test (9 [95% CI, 8.1-10.4] versus 11 [95% CI, 10.0-11.0], p = 0.06), or American Shoulder and Elbow Surgeons scores (80 [95% CI, 72-88] versus 88 [95% CI, 84-92], p = 0.08) 1 year after arthroscopic rotator cuff repair. With the numbers available, distressed patients also were not different from nondistressed patients in terms of the amount of improvement in scores between preoperative assessment and 1-year followup on the VAS for pain (3 [95% CI, 2.2-4.1] versus 2 [95% CI, 1.4-2.9], p = 0.10), Simple Shoulder Test (5.2 [95% CI, 3.7-6.6] versus 5.0 [95% CI, 4.2-5.8], p = 0.86), or American Shoulder and Elbow Surgeons scale (38 [95% CI, 29-47] versus 30 [95% CI, 25-36], p = 0.16). The prevalence of psychological distress in our patient population was lower at 1 year after surgery 14 of 70 (20%) versus 35 of 85 (41%) preoperatively (odds ratio, 0.36; 95% CI, 0.17-0.74; p = 0.005). CONCLUSIONS: Mild to moderate levels of distress did not diminish patient-reported outcomes to a clinically important degree in this small series of patients with rotator cuff tears. This contrasts with reports from other areas of orthopaedic surgery and may be related to a more self-limited course of symptoms in patients with rotator cuff disease or possibly to a beneficial effect of rotator cuff repair on sleep quality or other unrecognized determinants of psychosocial status. LEVEL OF EVIDENCE: Level I, prognostic study.

Does Rotator Cuff Repair Improve Psychologic Status and Quality of Life in Patients With Rotator Cuff Tear?

BACKGROUND: Recently, psychological status, patient-centered outcomes, and health-related quality of life (HRQoL) in patients with scheduled or who underwent orthopaedic surgeries have been emphasized. The relationship between preoperative psychological status and postoperative clinical outcome in patients with rotator cuff repair has not yet been investigated. QUESTIONS/PURPOSES: The primary objective of this study was to investigate changes in psychological status (depression, anxiety, insomnia) and HRQoL after rotator cuff repair. The secondary objective was to assess whether preoperative depression, anxiety, and insomnia predict clinical outcome after rotator cuff repair. METHODS: Forty-seven patients who underwent rotator cuff repair prospectively completed the visual analog scale (VAS) pain score, the UCLA Scale, the American Shoulder and Elbow Surgeons' Scale (ASES), the Hospital Anxiety and Depression Scale (HADS), the Pittsburgh Sleep Quality Index (PSQI), and the World Health Organization Quality-of-life Scale Abbreviated Version (WHOQOL-BREF) before surgery and at 3, 6, and 12 months after surgery. Repeated-measures analysis of variance was used to evaluate the serial changes in psychological parameters and outcome measurements. The chi-square test was also used to compare preoperative and postoperative prevalence of depression, anxiety, and insomnia. Finally, multiple regression analysis was applied to determine the relationship between preoperative psychological status and postoperative clinical outcome. RESULTS: With surgery, depression, anxiety, and insomnia decreased, whereas quality of life increased. The mean HADS-D and HADS-A scores and the mean PSQI score decreased from 3.7 ± 3.3, 4.3 ± 4.3, and 6.6 ± 3.6, respectively, before surgery to 2.1 ± 2.3, 1.4 ± 2.4, and 4.2 ± 3.3, respectively, at 12 months after surgery (HADS-D mean difference 1.6 [95% confidence interval {CI}, 0.6-2.6], p = 0.003; HADS-A mean difference 2.9 [1.5-4.4], p < 0.001; PSQI mean difference 2.4 [1.3-3.4], p < 0.001). The mean WHOQOL-BREF score increased from 60.4 ± 11.0 before surgery to 67.4 ± 11.8 at 12 months after surgery (mean difference -7.0 [95% CI, -10.7 to -3.4], p < 0.001). At 12 months after surgery, there were decreases in the prevalence of depression (six of 47 [22.8%] versus three of 47 [6.4%], p = 0.002), anxiety (11 of 47 [23.4%] versus two of 47 [4.3%], p = 0.016), and insomnia (33 of 47 [70.2%] versus 20 of 47 [42.6%], p = 0.022). Preoperative HADS-depression, HADS-anxiety, and PSQI scores did not correlate with the VAS pain score, UCLA, or ASES scores at 12 months after surgery. CONCLUSIONS: Psychological status and HRQoL improved with decreasing pain and increasing functional ability from 3 months after surgery. Preoperative depression, anxiety, and insomnia did not predict poor outcome after rotator cuff repair. Our findings suggest that successful rotator cuff repair may improve psychological status and HRQoL. LEVEL OF EVIDENCE: Level II, prospective study.

Psychological distress negatively affects self-assessment of shoulder function in patients with rotator cuff tears.

BACKGROUND: In many areas of orthopaedics, patients with greater levels of psychological distress report inferior self-assessments of pain and function. This effect can lead to lower-than-expected baseline scores on common patient-reported outcome scales, even those not traditionally considered to have a psychological component. QUESTIONS/PURPOSES: This study attempts to answer the following questions: (1) Are higher levels of psychological distress associated with clinically important differences in baseline scores on the VAS for pain, the Simple Shoulder Test, and the American Shoulder and Elbow Surgeons score in patients undergoing arthroscopic rotator cuff repair? (2) Does psychological distress remain a negative predictor of baseline shoulder scores when other clinical variables are controlled? METHODS: Eighty-five patients with full-thickness rotator cuff tears were prospectively enrolled. Psychological distress was quantified using the Distress Risk Assessment Method questionnaire. Patients completed baseline self-assessments including the VAS for pain, the Simple Shoulder Test, and the American Shoulder and Elbow Surgeons score. Age, sex, BMI, smoking status, American Society of Anesthesiologists classification, tear size, and tear retraction were recorded for each patient. Bivariate correlations and multivariate regression models were used to assess the effect of psychological distress on patient self-assessment of shoulder pain and function. RESULTS: Distressed patients reported higher baseline VAS scores (6.7 [95% CI, 4.4-9.0] versus 2.9 [95% CI, 2.3-3.6], p = 0.001) and lower baseline Simple Shoulder Test (3.7 [95% CI, 2.9-4.5] versus 5.7 [95% CI 5.0-6.4], p = 0.001) and American Shoulder and Elbow Surgeons scores (39 [95% CI, 34-45] versus 58 [95% CI, 53-63], p < 0.001). Distress remained associated with higher VAS scores (p = 0.001) and lower Simple Shoulder Test (p < 0.001) and American Shoulder and Elbow Surgeons scores (p < 0.001) when age, sex, BMI, American Society of Anesthesiologists classification, smoking status, tear size, and tear retraction were controlled. CONCLUSIONS: Higher levels of psychological distress are associated with inferior baseline patient self-assessment of shoulder pain and function using the VAS, the Simple Shoulder Test, and the American Shoulder and Elbow Surgeons score. Longitudinal followup is warranted to clarify the relationship between distress and self-perceived disability and the effect of distress on postoperative outcomes after arthroscopic rotator cuff repair.

Living with a symptomatic rotator cuff tear 'bad days, bad nights': a qualitative study.

BACKGROUND: Rotator cuff tears are a common cause of shoulder pain. There is an absence of information about symptomatic rotator cuffs from the patients' perspective; this limits the information clinicians can share with patients and the information that patients can access via sources such as the internet. This study describes the experiences of people with a symptomatic rotator cuff, their symptoms, the impact upon their daily lives and the coping strategies utilised by study participants. METHODS: An interpretive phenomenological analysis approach was used. 20 participants of the UKUFF trial (The United Kingdom Rotator Cuff Surgery Trial) agreed to participate in in-depth semi-structured interviews about their experiences about living with a symptomatic rotator cuff tear. Interviews were digitally recorded and fully transcribed. Field notes, memos and a reflexive diary were used. Data was coded in accordance with interpretive phenomenological analysis. Peer review, code-recode audits and constant comparison of data, codes and categories occurred throughout. RESULTS: The majority of patients described intense pain and severely disturbed sleep. Limited movement and reduced muscle strength were described by some participants. The predominantly adverse impact that a symptomatic rotator cuff tear had upon activities of daily living, leisure activities and occupation was described. The emotional and financial impact and impact upon caring roles were detailed. Coping strategies included attempting to carry on as normally as possible, accepting their condition, using their other arm, using analgesics, aids and adaptions. CONCLUSIONS: Clinicians need to appreciate and understand the intensity and shocking nature of pain that may be experienced by participants with known rotator cuff tears and understand the detrimental impact tears can have upon all areas of patient's lives. Clinicians also need to be aware of the potential emotional impact caused by cuff tears and to ensure that patients needing help for conditions such as depression are speedily identified and provided with support, explanation and appropriate treatment.

Ability to perform a single heel-rise is significantly related to patient-reported outcome after Achilles tendon rupture.

This study evaluated the short-term recovery of function after an acute Achilles tendon rupture, measured by a single-legged heel-rise test, with main emphasis on the relation to the patient-reported outcomes and fear of physical activity and movement (kinesiophobia). Eighty-one patients treated surgically or non-surgically with early active rehabilitation after Achilles tendon rupture were included in the study. Patient's ability to perform a single-legged heel-rise, physical activity level, patient-reported symptoms, general health, and kinesiophobia was evaluated 12 weeks after the injury. The heel-rise test showed that 40 out of 81 (49%) patients were unable to perform a single heel-rise 12 weeks after the injury. We found that patients who were able to perform a heel-rise were significantly younger, more often of male gender, reported a lesser degree of symptoms, and also had a higher degree of physical activity at 12 weeks. There was also a significant negative correlation between kinesiophobia and all the patient-reported outcomes and the physical activity level. The heel-rise ability appears to be an important early achievement and reflects the general level of healing, which influences patient-reported outcome and physical activity. Future treatment protocols focusing on regaining strength early after the injury therefore seem to be of great importance. Kinesiophobia needs to be addressed early during the rehabilitation process.

The impact of flexor tendon rehabilitation restrictions on individuals' independence with daily activities: implications for hand therapists.

STUDY DESIGN: Descriptive, grounded theory. PURPOSE: This study identified activity limitations which individuals with flexor tendon lacerations experience post-repair and explored methods they used to support participation in life roles. The role of hand therapy during the period of restricted hand use is discussed. METHODS: Standardized interviews with 19 individuals 6-12 months after flexor tendon repair (FTR) were recorded and thematic analysis was performed. Descriptive and nonparametric statistics were used to analyze quantitative data generated through these interviews. RESULTS: Patients struggled to fulfill life roles during the period of restricted hand use following FTR. Most participants asked other individuals for assistance; however, 59% of the participants removed their injured fingers from the orthosis in order to use their hand to perform activities. All of the participants' hand therapists instructed them in orthotic wear and activity restrictions and most addressed pain management, but few addressed how to perform meaningful activities and participate in life roles during the period of restricted hand use. Participants who did receive these types of interventions perceived that they were very useful. CONCLUSIONS: During the phase of restricted hand use following FTR, it is important for hand therapists to address activity performance and participation in meaningful life roles, in addition to ensuring the integrity and function of the healing tendon. This can include instruction in one-handed methods, use of adaptive equipment, and exploration of accommodations needed at work. LEVEL OF EVIDENCE: III.

The Achilles tendon total rupture score: a study of responsiveness, internal consistency and convergent validity on patients with acute Achilles tendon ruptures.

BACKGROUND: The Achilles tendon Total Rupture Score was developed by a research group in 2007 in response to the need for a patient reported outcome measure for this patient population. Beyond this original development paper, no further validation studies have been published.Consequently the purpose of this study was to evaluate internal consistency, convergent validity and responsiveness of this newly developed patient reported outcome measure within patients who have sustained an isolated acute Achilles tendon rupture. METHODS: Sixty-four eligible patients with an acute rupture of their Achilles tendon completed the Achilles tendon Total Rupture Score alongside two further patient reported outcome measures (Disability Rating Index and EQ 5D). These were completed at baseline, six weeks, three months, six months and nine months post injury. The Achilles tendon Total Rupture Score was evaluated for internal consistency, using Cronbach's alpha, convergent validity, through correlation analysis and responsiveness, by analysing floor and ceiling effects and calculating its relative efficiency in comparison to the Disability Rating Index and EQ 5D scores. RESULTS: The Achilles tendon Total Rupture Score demonstrated high internal consistency (Cronbachs alpha > 0.8) and correlated significantly (p < 0.001) with the Disability Rating Index at five time points (pre-injury, six weeks, three, six and nine months) with correlation coefficients between -0.5 and -0.9. However, the confidence intervals were wide. Furthermore, the ability of the new score to detect clinically important changes over time (responsiveness) was shown to be greater than the Disability Rating Index and EQ 5D. CONCLUSIONS: A universally accepted outcome measure is imperative to allow comparisons to be made across practice. This is the first study to evaluate aspects of validity of this newly developed outcome measure, outside of the developing centre. The ATRS demonstrated high internal consistency and responsiveness, with limited convergent validity. This research provides further support for the use of this outcome measure, however further research is required to advocate its universal use in patients with acute Achilles tendon ruptures. Such areas include inter-rater reliability and research to determine the minimally clinically important difference between scores.All authors have read and concur with the content of this manuscript.

Scoring systems for the functional assessment of patients with rotator cuff pathology.

Ideally, an outcome instrument measures phenomena that are directly relevant to the patient and provides a comprehensive assessment of the impact of a condition on the patient's daily life. During the past decades, several rating scales have been developed to assess the functional status of patients with shoulder pain. Several scoring systems are currently available for the evaluation of patients with rotator cuff pathology. Each of them evaluates shoulder function using specific variables. The main features of these scoring systems are presented in this review. Although many scoring systems are commonly used to evaluate shoulder function, we are still far from a single outcome evaluation system, which is reliable, valid, and sensitive to clinically relevant changes, takes into account both patient's and physician's perspective, and is short and practical to use.

Does the upward migration index predict function and quality of life in arthroscopic rotator cuff repair?

BACKGROUND: Although upward humeral head migration is a well-recognized phenomenon in patients with tears of the cuff, it is unclear whether it relates to patient function after cuff repair. The upward migration index (UMI) assesses proximal migration of the humeral head while controlling for patients' bony morphologic features. QUESTIONS/PURPOSES: We asked whether functional and quality-of-life (QOL) improvement occurs longitudinally in patients with low, moderate, or high degrees of proximal humeral migration after arthroscopic cuff repair and whether differences occur between groups. PATIENTS AND METHODS: We retrospectively reviewed 118 patients with full-thickness tears treated by arthroscopic cuff repair. Patients were divided into three groups depending on the severity of preoperative proximal humeral migration seen on MRI. We determined function using two functional scores and the Western Ontario Rotator Cuff Index (a QOL index). Evaluations were performed preoperatively and 6 and 12 months postoperatively. A general linear model analysis controlled for patient characteristics, including the UMI, to determine their effects on functional and QOL scores. RESULTS: Function and QOL improved after surgery in all three groups. The UMI did not correlate with final functional or QOL scores. Six-month functional and QOL scores correlated with final scores. The best predictor of final strength was initial strength. CONCLUSIONS: Preoperative UMI did not correlate with functional or QOL improvements after surgery. The data suggest substantial proximal migration of the humeral head, as measured by the UMI, should not be considered a contraindication to arthroscopic rotator cuff repair.

Patients with workers' compensation claims have worse outcomes after rotator cuff repair.

BACKGROUND: Previous studies have demonstrated varying correlations between Workers' Compensation status and the outcome of rotator cuff repair. However, none of those studies have formally accounted for potential confounding factors with multivariable analysis. We hypothesized that patients with Workers' Compensation claims who undergo rotator cuff repair have worse outcomes, even after controlling for confounding factors. METHODS: One hundred and twenty-five patients (including thirty-nine with Workers' Compensation claims) who underwent unilateral primary repair of a chronic rotator cuff tear by a single surgeon were studied prospectively and were evaluated one year postoperatively, prior to the settlement of any claims. Outcomes were assessed with the Simple Shoulder Test (SST); the Disabilities of the Arm, Shoulder and Hand (DASH) index; three visual analog scales (shoulder pain, shoulder function, and quality of life); and the Short Form-36 (SF-36). RESULTS: Patients in the Workers' Compensation group were significantly younger, had greater work demands, and had lower marital rates, education levels, and preoperative expectations for the outcome of treatment as compared with those in the non-Workers' Compensation group (p = 0.001 to 0.016). Preoperatively, patients in the Workers' Compensation group had significantly lower scores on the SST, the SF-36 Physical Function scale, and the SF-36 Social Function scale (p = 0.01 to 0.038). One year postoperatively, those patients reported worse performance on the SST, the DASH, all three visual analog scales, and the SF-36 (p = 0.0007 to 0.05) and had worse improvement on the DASH, the visual analog scales for shoulder pain and function, and the SF-36 Bodily Pain and Role Emotional scales (p = 0.0028 to 0.038). Multivariable analysis controlling for age, sex, comorbidities, smoking, marital status, education, duration of symptoms, work demands, expectations, and tear size confirmed that Workers' Compensation status was an independent predictor of worse DASH scores. CONCLUSIONS: Patients with Workers' Compensation claims report worse outcomes, even after controlling for confounding factors. The present study provides further evidence that the existence of a Workers' Compensation claim portends a less robust outcome following rotator cuff repair. LEVEL OF EVIDENCE: Prognostic Level I.

UNLABELLED: Our objective was to determine the long-term functional and quality-of-life outcomes for patients with rotator cuff tears receiving conservative treatment. We also studied correlations between the Constant and SF-36 scores. MATERIAL AND METHODS: This was a prospective survey carried out on patients having consulted in our Rehabilitation Department between January 1995 and December 2004 for radiologically-confirmed rotator cuff tears and having received medical treatment combined with a rehabilitation programme. The outcome measures used in our study were as follows: degree of motion, muscle strength, degree of pain on a visual analogical scale (VAS) and scores on the Constant and SF-36 scales. RESULTS: The study population consisted of 38 women and 21 men (mean age: 61 years; range 46-75). The mean final outcome measurements were taken after an average of seven years of follow-up (range: 4-12). The VAS score for pain at rest dropped from 68.3+/-31 to 28.3+/-12 (p<10(-3)) over the follow-up period. The score for pain during effort fell from 82.5+/-36 to 40.3+/-15. In all cases, active joint mobility was better at the final assessment (p<0.001). The Constant score rose from 28.8+/-14.2 to 51.6+/-21.8. The SF36 score showed a 16% improvement. Sixty-two percent of patients were satisfied or very satisfied with this treatment. The change over time was rated as good to very good by 42 patients (71.8%). The observed improvement in quality of life was correlated with reduced pain at rest (r=0.62) and during effort (r=0.59) and with the increased Constant score. CONCLUSION: Our results underline the benefits (in terms of short- and long-term pain reduction, functional improvements and better quality of life) of an individualized rehabilitation programme (combined with medical treatment) in cases of rotator cuff tears.
