RELIABILITY OF GONIOMETER RECORDS APPLICATION FOR MEASURING RANGE OF MOTION OF KNEE JOINT IN NORMAL HEALTHY INDIVIDUAL

Total Knee Arthroplasty (TKA) using standard artificial knee implant has a limitation in restriction in the range of motion and freedom of movements'. This study was worked out to compare the kinematics of a reconstructed 3D knee with standard and high flexion artificial knee designs. A CT bone model reconstructed with MIMICS for a 3D normal knee joint and the simulation was done for normal knee, standard version of artificial knee as well as the high flexion knee designs. The results of the analyses, provides us an insight that high flexion designs were most suited and gives increased range of motion and also provides an additional degree of freedom so that it almost mimics the normal knee movement. The high flexion design when tested under simulated environment provided a better functionality and increased movements. It was concluded that the normal knee has 6 degrees of freedom (DOF); the standard version has 1 rotation and 1 translation. The high flexion design provides 2 rotations and 1 translation.

Introduction Diagnostic accuracy is one of the key considerations of telemedicine usage in orthopedic surgery. The aim of this study was to determine the optimal patient positioning to achieve accurate and reliable visual estimation of the knee joint range of motion over a digital platform for telemedicine. Methods A single volunteer was recruited to perform a total of 120 discrete and random knee range of motion angles in three patient positions: sitting, standing and supine. The patient image was broadcast over a digital platform to six raters. The raters recorded their visual estimation of each discrete knee flexion angle independently. After each discrete knee flexion angle, a physical goniometer was used to obtain the actual flexion angle of the knee. Results A total of 120 discrete measurements (40 measurements in the sitting, standing, and supine positions each) were recorded by each of the six raters. The supine position resulted in the highest intraclass correlation of 0.97 (95% confidence interval: 0.98, 0.99). All three patient positions achieved low absolute difference between the goniometer and the raters with 5.6 degrees (95% limits of agreement: −21.0, 9.8) in sitting, 2.7 degrees (95% limits of agreement: −10.1, 15.4), and 1.2 degrees (95% limits of agreement: −9.8, 12.3) in the supine position. The supine position had the highest accuracy and reliability. Discussion Visual estimation of the knee joint range of motion over telemedicine is clinically accurate and reliable. Patients should be assessed in a supine position to obtain the highest accuracy and reliability for visual estimation of the knee joint range of motion during telemedicine.

Introduction: Knee osteoarthritis is a common degenerative disease in the elderly clinically. Cartilage damage, osteophyte formation, joint space narrowing and bone exposure are the main pathological changes, mainly manifested as joint cartilage degeneration [1]. Since the knee joint load of normal people is mainly conducted through the medial side of the knee joint, it is easy to cause degeneration of the medial compartment and then narrow the joint space, which leads to the medial deviation of the lower limb line and the varus deformity of the knee joint. For patients aged 55-65 years with unilateral ventricular osteoarthritis of the knee, the current surgical methods are mostly high tibial osteotomy (HTO) or unicomartmental knee arthroplasty (UKA)[2,3]. HTO always thought to improve lower limb power line to correct deformities, effectively relieve pain and improve function, is an effective method for treatment of osteoarthritis knee inside, high cut bone is typically used in younger patients and patients from physical activity, can effectively reduce the load and delay of knee joint cartilage lesion replacement time, while UKA is more suitable for old age is not active, activity, and patients needs more intense in terms of pain relief. Hypotheses: To investigate the clinical effect of unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) with tomofix internal fixation in the treatment of unicompartmental knee osteoarthritis. Methods: 60 patients with unicompartmental knee osteoarthritis and varus deformity of the knee joint were randomly divided into two groups: the UKA group (30 cases) and the HTO group (30 cases). The average follow-up time was 6 months, Scores preoperative and postoperative knee joint function, postoperative complications and postoperative pain satisfaction were compared. Results: The scores of HSS, VAS, femorotibial angle(FTA) and active range of motion(ROM) were 82.6 ± 12.9, 1.9 ± 0.8,173.2 ± 1.4,135.2 ± 1.6 in the group of unicompartmental knee arthroplasty (UKA);The scores of HSS, VAS(Visual Analogue Score), femorotibial angle(FTA) and active range of motion(ROM) after tomofix internal fixation used in the group of high tibial osteotomy (HTO)were 81.9 ± 14.3, 1.8 ± 0.9, 174.5 ± 1.8 and 121.1 ± 2.7 . There was no significant difference between the UKA group and HTO group in the scores of HSS, VAS and femorotibial angle(FTA) (P > 0.05). The active range of motion(ROM) of the HTO group was better than that of UKA group (P < 0.05). Conclusion: Both unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) with tomofix internal fixation can improve the knee joint function and symptoms in the treatment of medial compartment osteoarthritis, but the active range of motion(ROM) in HTO group is better than UKA group.

Muscular Performance

Context: Roller massagers are used as a recovery and rehabilitative tool to initiate muscle relaxation and improve range of motion (ROM) and muscular performance. However, research demonstrating such effects is lacking. Objective: To determine the effects of applying a roller massager for 20 and 60 seconds on knee-joint ROM and dynamic muscular performance. Design: Randomized controlled clinical trial. Setting: University laboratory. Patients or Other Participants: Ten recreationally active men (age = 26.6 ± 5.2 years, height = 175.3 ± 4.3 cm, mass = 84.4 ± 8.8 kg). Intervention(s): Participants performed 3 randomized experimental conditions separated by 24 to 48 hours. In condition 1 (5 repetitions of 20 seconds) and condition 2 (5 repetitions of 60 seconds), they applied a roller massager to the quadriceps muscles. Condition 3 served as a control condition in which participants sat quietly. Main Outcome Measure(s): Visual analog pain scale, electromyography (EMG) of the vastus lateralis (VL) and biceps femoris during roller massage and lunge, and knee-joint ROM. Results: We found no differences in pain between the 20-second and 60-second roller-massager conditions. During 60 seconds of roller massage, pain was 13.5% (5.7 ± 0.70) and 20.6% (6.2 ± 0.70) greater at 40 seconds and 60 seconds, respectively, than at 20 seconds (P < .05). During roller massage, VL and biceps femoris root mean square (RMS) EMG was 8% and 7%, respectively, of RMS EMG recorded during maximal voluntary isometric contraction. Knee-joint ROM was 10% and 16% greater in the 20-second and 60-second roller-massager conditions, respectively, than the control condition (P < .05). Finally, average lunge VL RMS EMG decreased as roller-massage time increased (P < .05). Conclusions: Roller massage was painful and induced muscle activity, but it increased knee-joint ROM and neuromuscular efficiency during a lunge.

AbstractThis study aimed to develop a rabbit model of knee contracture in extension and investigate the natural history of motion loss and time-dependent changes in the joint capsule after immobilization. We immobilized the unilateral knee joints of 32 rabbits by maintaining the knee joint in a plaster cast at full extension. Eight rabbits were euthanized at 2, 4, 6, and 8 weeks after casting, respectively, and the lower extremities were disarticulated at the hip joint. Eight control group rabbits that did not undergo immobilization were also examined. We assessed the progression of joint contracture by measuring the joint range of motion, evaluating the histologic alteration of the capsule, and assessing the mRNA levels of transforming growth factor β1 (TGF-β1) in the anterior and posterior joint capsules. After 2 weeks of joint immobilization, the knee joint range of motion was limited, the synovial membrane of the suprapatellar and posterior joint capsules was thickened, the collagen deposition was increased, and the mRNA levels of TGF-β1 were elevated in the anterior and posterior joint capsules. These changes progressed rapidly until 6 weeks of immobilization and may advance slowly after 6 weeks. Joint contracture developed at the early stage of immobilization and progressed over time. The changes in the anterior and posterior joint capsules after joint immobilization may contribute to the limitation in flexion. The elevated mRNA expression of TGF-β1 may be related to joint capsule fibrosis and may be one of the causes of joint contracture.
