Goniometer assessment is widely used to assess the range of motion in the post-operative period. This study aimed to determine the inter-rater ability of a smartphone application and visual estimation of the knee joint after total knee arthroplasty among different professions that commonly work together and compare whether any method is superior to another. METHOD Range of motion measurements was performed by four clinicians as two physiotherapists and two orthopedic fellows. They utilized the Goniometer Reports application for smartphones, universal goniometer, and visual estimation to measure angles of knees which was operated. A two-way mixed model of intra-class correlation coefficient (ICC) with a 95% confidence level was used to assess inter-rater reliability. RESULTS Thirteen patients (11 female) and 20 knees (10 right) were assessed. The ICCs were found excellent both for between methods and between raters. CONCLUSION Our results show that technology seems a more accurate way to determine the knee range of motion after knee arthroplasty compared to senses. However, in lack of technological resources or time, or to avoid possible infection, visual estimation also could provide useful information.

The purpose of this study was to compare the results of revision total knee arthroplasty between V-Y quadricepsplasty (QP) and quadriceps snip (QS) approaches. Methods: In the study, 92 knees with follow-up of 12-108 months which were operated by using QP (55) and QS (37) were evaluated retrospectively. Measurements were taken by using universal transparent goniometer, also varus valgus deformities, knee flexion angles, instability, Hospital for Special Surgery and Lower Extremity Functional Scale scores, functional condition of the knee and activity levels of the patients were evaluated cross-sectionally. Results: Statistically significant difference was not found regarding extensor restriction, varus or valgus deformities, knee flexion angles, flexor and extensor muscular strength, Hospital for Special Surgery and Lower Extremity Functional Scale score (P > .05). Conclusion: QP is a preferable method which allows a wider arthrotomy for stiff knees and revision knee surgery, and provides larger access to the joint. Choosing this incision does not bring disadvantage in terms of extensor mechanism.

These alterations in scapular kinematics such as changes in the normal position or any abnormal motion of the scapula during active motions are defined as “’Scapular Dyskinesis (SD)”. Relationship between tight muscles and scapular kinematics has been investigated. Pectoralis Minor Muscle Tightness (PMMT) effects scapular motion and make changes in scapular kinematics. Although there are some studies indicating a possible relationship between PMM or Upper Trapezius Muscle Tightness (UTMT) and SD, this relationship hasn’t been investigated yet. The aim of this study was to evaluate the influence of PMMT and UTMT on SD in an asymptomatic population. Methods: One-hundred-eleven participants (mean age: 22.73±3.45 years old, 222 arms, 42 Female-69 Male) were recruited. Subjects were eligible if they were ≥18 years of age, having active full shoulder motion an...

Understanding the effect of these muscle lengths on observable scapular dyskinesis may aid in determining risks and therefore making treatment decisions. Being aware of the magnitude of this effect would help gauge the significance of risks involved. Our aim was to evaluate the influence of pectoralis minor and upper trapezius lengths on scapular dyskinesis. Cross-sectional study. University research laboratory. Asymptomatic participants (n = 148; 296 arms) were evaluated. Scapular Dyskinesis Test (SDT) was used to identify scapular dyskinesis, Pectoralis Minor Index (PMI) and Upper Trapezius Length Testing were used to determine muscle length. SDT+ arms had shorter pectoralis minor resting length (PMI: 7.49 ± 0.38) (p &amp;amp;amp;amp;lt; 0.001) and greater incidence of short upper trapezius (ISUT) (66.7%) (p &amp;amp;amp;amp;lt; 0.001) compared to SDT- arms (PMI:8.58 ± 0.75, ISUT:22.5%). With each decrease in PMI, the likelihood of having scapular dyskinesis increased 96% (p &amp;amp;amp;amp;lt; 0.001). Arms with short upper trapezius were 2.049 times more likely to exhibit scapular dyskinesis than those with normal length (p = 0.042). Having a shorter pectoralis minor and upper trapezius length substantially increased the likelihood of having visually observable scapular dyskinesis.

Methods: The study was designed as a test-retest research. Thirty-three patients who would undergo bilateral TKA were recruited. The tests 30 CST and 50 FWT were performed twice on the same day with 5-minute intervals, respectively. Between the first and second tests, patients waited for an hour on sitting position in order to prevent fatigue. In addition to these tests, we registered the knee pain experienced by the patients using a 100 mm VAS scale. Results: The 50 FWT and 30 CST showed excellent reliability. ICC for 50 FWT and 30 CST were 0.97 and 0.92, respectively. SRD95 was 1.07 for 50 FWT and 0.96 for 30 CST. Conclusions: According to results of this study, both 50 FWT and 30 CST have excellent reliability in patients with TKA. These tests are simple, no time consuming and constitute sensitive methods to measure the functional performance in patients with TKA in the clinical settings. Clinicians and researchers may use these tests to quantify even small changes in functional performance for patients with TKA. Level of Evidence III, Diagnostic Study.

Assessment of walking after total hip arthroplasty (THA) provides important information about the healing process. Walking endurance, an important functional component of walking, can be reliably measured with the 6-minute walk test (6 mWT). Even though the 6 mWT is commonly used in patients with THA, its reliability has never been reported for this patient population. The aim of this study is to assess the reliability of the test-retest 6 mWT after THA. Methods: Thirty-four patients with THA performed two test trials on the same day, separated by a one hour seated rest. To assess reliability, intra-class correlation coefficient (ICC 2,1), standard error of measurement (SEM), and smallest real difference (SRD) were calculated. results: The 6 mWT showed a high reliability. The patients walked 3.71 metres more at the end of the second 6 mWT in comparison with the first test. The ICC 2,1 (AS 95), SEM (m), SEM 95 (m) and SRD 95 (m) were 0.96 (0.92), 3.67, 7.19, and 10.17 m respectively. conclusions: Reliability of the 6 mWT was high in patients with THA. The 6 mWT is a simple and sensitive method to measure the functional performance in patients with THA in the clinical setting. Moreover, clinicians and researchers can use the 6 mWT to quantify even small changes in functional performance after THA.

Walking and stair climbing have been identified by clinicians and patients as critical functional activities before and after total hip arthroplasty (THA). Testing the ability to manage steps has been commonly used in clinical and research settings because it is an inexpensive and simple way to measure functional status after THA. The frequent use of this test supports studies seeking evidence to validate stair test (ST) as a measure of physical performance in subjects with THA. The aim of this study is to determine the test-retest reliability of the 9-step ST in patients with THA. Patients performed twice trials for the ST on the same day with one hour interval. To assess test-retest reliability, the intra-class correlation coefficient - ICC (2,1), standard error of measurement (SEM), minimal detectable change at the 90% confidence level (MDC90) were calculated.

Health Assessment Questionnaire (HAQ), The Western Ontario and McMaster Universities Arthritis Index (WOMAC) was used for functional evaluation and IL-6 were analyzed for anti-inflammatory status in both groups. Control group did not get any exercise intervention. However, BETY group were participated to exercise sessions 3 times a week for 10 weeks. All measurements were repeated after 10 weeks in both groups. Results: WOMAC pain, physical function and WOMAC total score values were decreased significantly (p<0.05) in exercise group. However HAQ, WOMAC stiffness score were remained stable according to pretreatment values in this group (p>0.05). Although any significant change in IL-6 in both groups were not observed, IL-6 decreased in BETY group. Moreover, TNF-a showed significant increase in control group (p<0.05). No change was observed for other values between pre-and post-treatment in control group (p>0.05). There was no difference between two groups after 10 weeks (p>0.05).

These alterations in scapular kinematics such as changes in the normal position or any abnormal motion of the scapula during active motions are defined as “’Scapular Dyskinesis (SD)”. Relationship between tight muscles and scapular kinematics has been investigated. Pectoralis Minor Muscle Tightness (PMMT) effects scapular motion and make changes in scapular kinematics. Although there are some studies indicating a possible relationship between PMM or Upper Trapezius Muscle Tightness (UTMT) and SD, this relationship hasn’t been investigated yet. The aim of this study was to evaluate the influence of PMMT and UTMT on SD in an asymptomatic population. Methods: One-hundred-eleven participants (mean age: 22.73±3.45 years old, 222 arms, 42 Female-69 Male) were recruited. Subjects were eligible if they were ≥18 years of age, having active full shoulder motion an...

Understanding the effect of these muscle lengths on observable scapular dyskinesis may aid in determining risks and therefore making treatment decisions. Being aware of the magnitude of this effect would help gauge the significance of risks involved. Our aim was to evaluate the influence of pectoralis minor and upper trapezius lengths on scapular dyskinesis. Cross-sectional study. University research laboratory. Asymptomatic participants (n = 148; 296 arms) were evaluated. Scapular Dyskinesis Test (SDT) was used to identify scapular dyskinesis, Pectoralis Minor Index (PMI) and Upper Trapezius Length Testing were used to determine muscle length. SDT+ arms had shorter pectoralis minor resting length (PMI: 7.49 ± 0.38) (p &amp;amp;amp;amp;lt; 0.001) and greater incidence of short upper trapezius (ISUT) (66.7%) (p &amp;amp;amp;amp;lt; 0.001) compared to SDT- arms (PMI:8.58 ± 0.75, ISUT:22.5%). With each decrease in PMI, the likelihood of having scapular dyskinesis increased 96% (p &amp;amp;amp;amp;lt; 0.001). Arms with short upper trapezius were 2.049 times more likely to exhibit scapular dyskinesis than those with normal length (p = 0.042). Having a shorter pectoralis minor and upper trapezius length substantially increased the likelihood of having visually observable scapular dyskinesis.

Methods: The study was designed as a test-retest research. Thirty-three patients who would undergo bilateral TKA were recruited. The tests 30 CST and 50 FWT were performed twice on the same day with 5-minute intervals, respectively. Between the first and second tests, patients waited for an hour on sitting position in order to prevent fatigue. In addition to these tests, we registered the knee pain experienced by the patients using a 100 mm VAS scale. Results: The 50 FWT and 30 CST showed excellent reliability. ICC for 50 FWT and 30 CST were 0.97 and 0.92, respectively. SRD95 was 1.07 for 50 FWT and 0.96 for 30 CST. Conclusions: According to results of this study, both 50 FWT and 30 CST have excellent reliability in patients with TKA. These tests are simple, no time consuming and constitute sensitive methods to measure the functional performance in patients with TKA in the clinical settings. Clinicians and researchers may use these tests to quantify even small changes in functional performance for patients with TKA. Level of Evidence III, Diagnostic Study.

Assessment of walking after total hip arthroplasty (THA) provides important information about the healing process. Walking endurance, an important functional component of walking, can be reliably measured with the 6-minute walk test (6 mWT). Even though the 6 mWT is commonly used in patients with THA, its reliability has never been reported for this patient population. The aim of this study is to assess the reliability of the test-retest 6 mWT after THA. Methods: Thirty-four patients with THA performed two test trials on the same day, separated by a one hour seated rest. To assess reliability, intra-class correlation coefficient (ICC 2,1), standard error of measurement (SEM), and smallest real difference (SRD) were calculated. results: The 6 mWT showed a high reliability. The patients walked 3.71 metres more at the end of the second 6 mWT in comparison with the first test. The ICC 2,1 (AS 95), SEM (m), SEM 95 (m) and SRD 95 (m) were 0.96 (0.92), 3.67, 7.19, and 10.17 m respectively. conclusions: Reliability of the 6 mWT was high in patients with THA. The 6 mWT is a simple and sensitive method to measure the functional performance in patients with THA in the clinical setting. Moreover, clinicians and researchers can use the 6 mWT to quantify even small changes in functional performance after THA.

Walking and stair climbing have been identified by clinicians and patients as critical functional activities before and after total hip arthroplasty (THA). Testing the ability to manage steps has been commonly used in clinical and research settings because it is an inexpensive and simple way to measure functional status after THA. The frequent use of this test supports studies seeking evidence to validate stair test (ST) as a measure of physical performance in subjects with THA. The aim of this study is to determine the test-retest reliability of the 9-step ST in patients with THA. Patients performed twice trials for the ST on the same day with one hour interval. To assess test-retest reliability, the intra-class correlation coefficient - ICC (2,1), standard error of measurement (SEM), minimal detectable change at the 90% confidence level (MDC90) were calculated.
