Ultrasonographic Measurement Of The Femoral Cartilage Thickness In Patients With Behcet'S Disease
'West Indian Medical Journal', 2014Co-Authors: Kara M, Tiftik T, Yildiz M., Cevik R., Ozcakar LAbstract:Objective: To evaluate femoral cartilage thickness in patients with Behcet's disease (BD) by using ultrasonography. Methods: Thirty-one patients with BD (18 M, 13 F; mean age: 32.87 +/- 8.5 years) and 31 age-, gender- and body mass index-matched healthy subjects were enrolled. Demographic features and medications of the patients were recorded. The femoral cartilage thicknesses of both knees were measured with a 7-12 MHz linear probe while subjects' knees were held in maximum flexion. Three mid-point measurements were taken from both knees: lateral femoral condyle (LFC), Intercondylar Area (ICA) and medial femoral condyle (MFC). Results: Cartilage measurements of BD patients were significantly thinner at the ICA (p = 0.009) and LFC (p = 0.007) on the left knee, and at the MFC on both sides (both p < 0.05). Left knee cartilage thickness value at MFC (p = 0.005) was decreased in BD patients with arthritis compared to the healthy control group. Conclusion: These preliminary findings of decreased femoral cartilage thickness in BD patients with arthritis should be complemented with future studies. However, the possibility of early knee joint degeneration and eventual osteoarthritis in BD should also be kept in mind.Wo

Femoral cartilage thickness measurements in healthy individuals: learning, practicing and publishing with TURK-MUSCULUS.
'IOS Press', 2014Co-Authors: Ozcakar L, Oken O, Akkaya N, Tunc H, Ünlü Z, Durmuş B, Baysal Ö, Altay Z, Tok F, Doğu BAbstract:BACKGROUND AND OBJECTIVES: Measurement of the femoral cartilage thickness by using in-vivo musculoskeletal ultrasonography (MSUS) has been previously shown to be a valid and reliable method in previous studies; however, to our best notice, normative data has not been provided before in the healthy population.The aim of our study was to provide normative data regarding femoral cartilage thicknesses of healthy individuals with collaborative use of MSUS. METHODS: This is across-sectional study run at Physical and Rehabilitation Medicine Departments of 18 Secondary and Tertiary Centers in Turkey. 1544 healthy volunteers (aged between 25-40 years) were recruited within the collaboration of TURK-MUSCULUS (Turkish Musculoskeletal Ultrasonography Study Group). Subjects who had a body mass index value of less than 30 and who did not have signs and symptoms of any degenerative/inflammatory arthritis or other rheumatic diseases, history of knee trauma and previous knee surgery were enrolled. Ultrasonographic measurements were performed axially from the suprapatellar window by using linear probes while subjects' knees were in maximum flexion. Three (mid-point) measurements were taken from both knees (lateral condyle, Intercondylar Area, medial condyle). RESULTS: A total of 2876 knees (of 817 M, 621 F subjects) were taken into analysis after exclusion of inappropriate images. Mean cartilage thicknesses were significantly lower in females than males (all p< 0.001). Thickness values negatively correlated with age; negatively (females) and positively (males) correlated with smoking. Men who regularly exercised had thicker cartilage than who did not exercise (all p < 0.05). Increased age (in both sexes) and absence of exercise (males) were found to be risk factors for decreased cartilage thicknesses. CONCLUSION: Further data pertaining to other countries would be interesting to uncover whether ethnic differences also affect cartilage thickness. Collaborative use of MSUS seems to be promising in this regard

ULTRASONOGRAPHIC MEASUREMENT OF FEMORAL CARTILAGE THICKNESS IN PATIENTS
'Acta Dermato-Venereologica', 2013Co-Authors: Kara M, Tiftik T, Oken O, Akkaya N, Tunc H, Ozcakar LAbstract:Objective: To assess femoral cartilage thickness in patients with spinal cord injury.Subjects: Forty-six patients with SCI (35 men, 11 women; mean age: 33.6 years (standard deviation 8.1) and 46 age-, sex- and body mass index (BMI)-matched healthy subjects were enrolled.Methods: Patients were evaluated with the American Spinal Injury Association (ASIA) Impairment Scale, Modified Ashworth Scale, Walking Index for Spinal Cord Injury, and Functional Independence Measurement. Mid-point ultrasonographic femoral cartilage thickness measurements were taken from the right lateral condyle, right Intercondylar Area, right medial condyle, left medial condyle, left Intercondylar Area and left lateral condyle.Results: Ultrasonographic measurements revealed significantly thicker values in the Intercondylar Areas (bilaterally) and the medial condyle (left knee) of patients with spinal cord injury compared with those of controls. When the subgroups were compared with their paired healthy controls, measurements pertaining to the motor complete group were found to be significantly thicker in the Intercondylar Areas (bilaterally) and the medial condyle (left knee). Cartilage thickness values correlated negatively with the duration of immobilization (for bilateral Intercondylar Areas), and with BMI and ASIA level (for bilateral lateral condyles).Conclusion: Femoral cartilage thicknesses were found to change after spinal cord injury, and to have a negative correlation with disease duration and severity. Future studies including histological evaluations may elucidate whether such changes are favourable for the knee joints of patients with spinal cord injury

Ultrasonographic measurement of the femoral cartilage thickness in patients with transfemoral amputation
'IOS Press', 2016Co-Authors: Onat Ş.Ş., Akkaya Nuray, Ekiz T, Özbudak Demir S, Malas F.Ü., Öztürk G.t., Kara MAbstract:OBJECTIVE: To compare the distal femoral cartilage thickness of the non-amputee sides in patients who had unilateral transfemoral amputation with those of healthy subjects by using ultrasound. METHODS: Thirty transfemoral amputees (27 male, 3 female) and 30 age-, sex-, and body mass index-matched healthy controls were included. Functional usage of the prosthesis was evaluated by using Houghton score. The cartilage thickness was measured from the following midpoints; medial femoral condyle (MFC), Intercondylar Area, and lateral femoral condyle. RESULTS: Thirty patients with unilateral transfemoral amputation (mean age; 38.6 ± 9.5 years) and 30 healthy controls (mean age; 38.4 ± 9.4 years) were included. Although femoral cartilage thicknesses were found to be lower for all measurements in the amputees, the difference reached significance only in the MFC (p = 0.031). In the patient group, cartilage thickness values did not correlate with age, duration of amputation, daily walking time, stump length or Houghton score. CONCLUSION: The distal femoral cartilage thickness seems to be decreased medially on the non-amputee sides of the transfemoral amputees when compared with the healthy subjects. Further studies concerning the follow-up designs, functional parameters and osteoarthritis scales are awaited. © 2016 - IOS Press and the authors. All rights reserved

Ultrasonographic evaluation of the femoral cartilage thickness after unilateral arthroscopic partial meniscectomy
'Springer Science and Business Media LLC', 2013Co-Authors: Akkaya Semih, Akkaya Nuray, Ozcakar L, Kiliç A., Sahin F., Atalay N.s., Ardic F.Abstract:Purpose: To assess the distal femoral cartilage after unilateral arthroscopic partial meniscectomy and to explore the relationship between cartilage thickness and various disease-/surgery-related parameters. Methods: Eighty-nine patients (42 M, 47 F) who had undergone arthroscopic partial meniscectomy surgery were evaluated. Ultrasonographic distal femoral cartilage thicknesses were measured with a 5-13-MHz linear probe (General Electric, Logiq P5) on mid-points of the lateral condyle, Intercondylar notch and medial condyle of operated and non-operated knees by a physician blinded to patients' data. Demographic features, duration after surgery, type of meniscal tear and site of meniscectomy were recorded. Results: Mean age of the patients was 51. 8 ± 12. 8 years (range 18-88). Mean body mass index was 29. 4 ± 4. 4 kg/m2 (range 18-38). Overall, in patients with degenerative meniscal tears, femoral cartilage thicknesses pertaining to all the three measured sites (lateral, Intercondylar and medial) were found to be decreased in the operated knees when compared with those of the non-operated knees (p = 0. 004, p = 0. 003, p = 0. 041, respectively), whereas in patients with non-degenerative tears, this decrease was significant only in the Intercondylar Area (p = 0. 038). When patients were grouped according to the duration (months) after their surgery (≤36, 37-48 and ≥49), cartilage thickness was similar between both knees in the first group, decreased at the lateral condyle (p = 0. 008) and Intercondylar Area (p = 0. 049) in the second group and decreased at all three sites (lateral, Intercondylar and medial) in the third group (p = 0. 015, p = 0. 005 and p = 0. 008, respectively). Conclusion: These findings would be considered as unfavourable with respect to weight-bearing, and thus, conservative measures to support relevant joints would strongly be kept in mind during clinical practice. Lastly, ultrasonography may be a convenient alternative imaging method for the evaluation of short- and medium-term cartilage loss in patients with arthroscopic partial meniscectomy.

Ultrasonographic measurement of the femoral cartilage thickness in patients with transfemoral amputation.
'IOS Press', 2016Co-Authors: Ekiz T, Akkaya N, Özbudak Demir S, Kara MAbstract:OBJECTIVE: To compare the distal femoral cartilage thickness of the non-amputee sides in patients who had unilateral transfemoral amputation with those of healthy subjects by using ultrasound. METHODS: Thirty transfemoral amputees (27 male, 3 female) and 30 age-, sex-, and body mass index-matched healthy controls were included. Functional usage of the prosthesis was evaluated by using Houghton score. The cartilage thickness was measured from the following midpoints; medial femoral condyle (MFC), Intercondylar Area, and lateral femoral condyle. RESULTS: Thirty patients with unilateral transfemoral amputation (mean age; 38.6 ± 9.5 years) and 30 healthy controls (mean age; 38.4 ± 9.4 years) were included. Although femoral cartilage thicknesses were found to be lower for all measurements in the amputees, the difference reached significance only in the MFC (p= 0.031). In the patient group, cartilage thickness values did not correlate with age, duration of amputation, daily walking time, stump length or Houghton score. CONCLUSION: The distal femoral cartilage thickness seems to be decreased medially on the non-amputee sides of the transfemoral amputees when compared with the healthy subjects. Further studies concerning the follow-up designs, functional parameters and osteoarthritis scales are awaited

Subjects: Forty-six patients with SCI (35 men, 11 women; mean age: 33.6 years (standard deviation 8.1) and 46 age-, sex- and body mass index (BMI)-matched healthy subjects were enrolled. Methods: Patients were evaluated with the American Spinal Injury Association (ASIA) Impairment Scale, Modified Ashworth Scale, Walking Index for Spinal Cord Injury, and Functional Independence Measurement. Mid-point ultrasonographic femoral cartilage thickness measurements were taken from the right lateral condyle, right Intercondylar Area, right medial condyle, left medial condyle, left Intercondylar Area and left lateral condyle. Results: Ultrasonographic measurements revealed significantly thicker values in the Intercondylar Areas (bilaterally) and the medial condyle (left knee) of patients with spinal cord injury compared with those of controls. When the subgroups were compared with their paired healthy controls, measurements pertaining to the motor complete group were found to be significantly thicker in the Intercondylar Areas (bilaterally) and the medial condyle (left knee). Cartilage thickness values correlated negatively with the duration of immobilization (for bilateral Intercondylar Areas), and with BMI and ASIA level (for bilateral lateral condyles). Conclusion: Femoral cartilage thicknesses were found to change after spinal cord injury, and to have a negative correlation with disease duration and severity. Future studies including histological evaluations may elucidate whether such changes are favourable for the knee joints of patients with spinal cord injury. © 2013 The Authors

INTERNATIONAL JOURNAL OF REHABILITATION RESEARCH
'Ovid Technologies (Wolters Kluwer Health)', 2012Co-Authors: Tunc HAbstract:The aim of the study was to evaluate the femoral cartilage thicknesses of hemiparetic patients after stroke using musculoskeletal ultrasonography and to determine whether there is any correlation between cartilage thicknesses and the clinical characteristics of the patients. Femoral cartilage thicknesses of both knees were measured in 87 (33 women, 54 men) hemiparetic patients. The mean age of the patients was 61.8 years (SD 11.1 years, range 32-87 years) and the mean duration of stroke was 12.3 months (SD 10.5 months, range 1-36 months). The outcome was measured in terms of motor recovery (Brunnstrom stages), spasticity (Modified Ashworth Scale), walking ability (Functional Ambulation Categories), and motor functioning (Functional Independence Measurement instrument). Ultrasonographic measurements were made axially from the suprapatellar window using linear probes while the patients' knees were held in maximum flexion. Three (midpoint) measurements were taken from both knees [lateral condyle (LFC), Intercondylar Area, and medial condyle (MFC)]. The mean cartilage thicknesses were found to be less on the paretic side (statistically significant only for LFC) when compared with the nonparetic side. Cartilage thickness values were found to be negatively correlated with the duration of immobilization (with paretic side LFC) and BMI (with both sides' MFC) and positively correlated with the Functional Independence Measurement motor score (with paretic side LFC) and the Functional Ambulation Categories scores (with both sides' LFC and MFC). Femoral cartilage is thinner on the paretic side in stroke patients. As the thickness values correlate with the duration of the disease and the ambulatory status of the patients, we suggest that early mobilization would be important in maintaining their cartilage integrity

Femoral cartilage thickness measurements in healthy individuals: learning, practicing and publishing with TURK-MUSCULUS.
'IOS Press', 2014Co-Authors: Ozcakar L, Oken O, Akkaya N, Tunc H, Ünlü Z, Durmuş B, Baysal Ö, Altay Z, Tok F, Doğu BAbstract:BACKGROUND AND OBJECTIVES: Measurement of the femoral cartilage thickness by using in-vivo musculoskeletal ultrasonography (MSUS) has been previously shown to be a valid and reliable method in previous studies; however, to our best notice, normative data has not been provided before in the healthy population.The aim of our study was to provide normative data regarding femoral cartilage thicknesses of healthy individuals with collaborative use of MSUS. METHODS: This is across-sectional study run at Physical and Rehabilitation Medicine Departments of 18 Secondary and Tertiary Centers in Turkey. 1544 healthy volunteers (aged between 25-40 years) were recruited within the collaboration of TURK-MUSCULUS (Turkish Musculoskeletal Ultrasonography Study Group). Subjects who had a body mass index value of less than 30 and who did not have signs and symptoms of any degenerative/inflammatory arthritis or other rheumatic diseases, history of knee trauma and previous knee surgery were enrolled. Ultrasonographic measurements were performed axially from the suprapatellar window by using linear probes while subjects' knees were in maximum flexion. Three (mid-point) measurements were taken from both knees (lateral condyle, Intercondylar Area, medial condyle). RESULTS: A total of 2876 knees (of 817 M, 621 F subjects) were taken into analysis after exclusion of inappropriate images. Mean cartilage thicknesses were significantly lower in females than males (all p< 0.001). Thickness values negatively correlated with age; negatively (females) and positively (males) correlated with smoking. Men who regularly exercised had thicker cartilage than who did not exercise (all p < 0.05). Increased age (in both sexes) and absence of exercise (males) were found to be risk factors for decreased cartilage thicknesses. CONCLUSION: Further data pertaining to other countries would be interesting to uncover whether ethnic differences also affect cartilage thickness. Collaborative use of MSUS seems to be promising in this regard
