“…Hence, it is plausible that strength deficits, especially in the quadriceps, may also occur in degenerative meniscal tear cohorts, a group known to have an increased risk of developing OA. In this context, isokinetic dynamometry is one of the most reliable and widespread approaches to assessing muscle strength [16]. Using this approach, we found no significant difference in concentric knee flexor or extensor (body weight adjusted) strength between groups at a velocity of 60 • /s and 180 • /s which can be explained by the rather short duration of the intervention program (6 weeks).…”

“…This is why it has been used as a means of muscle strengthening coupled with neuromuscular electrical stimulation intervention [11] in various pathologies of the knee such as gonarthrosis [12], and patellofemoral syndrome [13,14]. The reliability of the test results, notably for lower limb muscles, has enabled isokinetic dynamometers to be regarded as a standard for measuring muscular strength [15,16]. Indeed, isokinetic dynamometers as muscle strength assessment tools for meniscal lesion studies are well-documented [17][18][19][20][21].…”

Meniscal injuries are one of the most common intra-articular knee injuries. Different treatments are presented depending on the symptoms and duration of meniscus tears, such as arthroscopic partial meniscectomy, physiotherapy, or even pharmacological treatment. The purpose was to investigate the effect of a concentric isokinetic knee muscle strengthening program on strength, joint range of motion, physical performance, quality of life and pain tolerance in overweight/obese women with chronic meniscal lesions. Twenty-four overweight/obese women were randomized into two groups. A control group (CG) performed a usual rehabilitation program plus isokinetic muscle strengthening (IMS) in the continuous passive motion mode and measured with an isokinetic dynamometer. An experimental group (EG) performed the same program in combination with IMS in the isokinetic active mode. The peak torque of the knee extensors (PTE) and flexors (PTF), sit-to-stand test, stair climb test, joint amplitude, heel-to-buttock distance, Thessaly test, KOOS questionnaire of pain and quality of life were measured pre- and post-protocol. After the intervention, the sit–stand number for both groups was significantly higher (p < 0.001) and the time to climb stairs was significantly reduced for the EG (p < 0.001). A significant improvement in joint range of motion, life quality (p < 0.001), relief in knee pain (p < 0.001) and in the post-program evaluation at the EG (p < 0.05) was noted. There was no significant difference in PTE and PTF between groups at 60°/s and 180°/s. The IMS in the active mode could be an effective therapeutic modality in managing middle-aged patients suffering from a degenerative meniscal tear.

“…The isokinetic test has been shown to be a valid and reliable measurement of the strength of the knee flexor and extensor muscles (24). Low angular velocity tests are more accurate in the measurement of muscle strength and high angular velocity tests are used to evaluate the muscle function and endurance (25,26). The tests used in the present study were 60˚/sec and 180˚/sec angular velocity.…”

The aim of the present study was to compare the efficacy of hypertonic dextrose prolotherapy (HDP) with conventional physiotherapy (CPT) in improving symptoms in females with knee osteoarthritis (OA). The present study included 60 patients with a diagnosis of knee OA. The patients were randomly assigned to the HDP (n=30) and CPT (n=30) groups. The patients in the HDP group were treated with a dextrose injection into the knee joint (25% dextrose) and around the knee (15% dextrose) in two sessions for 1 month, while those in the CPT group received a hot pack, transcutaneous electrical nerve stimulation and therapeutic ultrasound in five sessions a week for 4 weeks. Prior to commencing the treatment, and at 1 and 3 months post-treatment, all the patients were evaluated using the visual analog scale (VAS), Western Ontario and McMaster Osteoarthritis Index (WOMAC), the goniometric measurement of active knee range of motion (ROM), a 50-m walking test and isokinetic knee muscle strength measurements. There were no statistically significant differences between the two groups as regards the demographic characteristics at pre-treatment (P>0.05). However, at 1 and 3 months post-treatment, the scores of all the outcome parameters were significantly improved in the HDP group compared with the CPT group (P<0.05 for all). In both groups, a significant improvement was observed in the VAS scores, WOMAC total values and ROM following the treatments, with the greatest improvement observed in the HDP group (P<0.001). The isokinetic quadriceps peak torque measurements were increased in both groups following treatment. All the scores exhibited a statistically significant improvement in the HDP group at both 1 and 3 months post-treatment. On the whole, the results of the present study demonstrate that both HDP and CPT are effective treatment modalities to relieve pain, and increase functionality and strength in patients with knee OA. However, greater improvements in pain and functionality can be achieved with prolotherapy.

“…In addition, impaired muscle function is usually noticed in patients with OA of the hip and knee [7]. Myers showed that adults with OA have decreased muscle strength and functional capacity [8]. Although, these studies provide insight into the possible muscle strength and functional deficits of this group of adults, they cannot provide convincing evidence, because the subjects were not well matched for variables such as age, body type, physical activity level, and stage of knee OA, each of which would have a significant effect on the process and prognosis of the disease.…”

Background: Osteoarthritis (OA) of the knees can affect the muscle function and functional performance of the surrounding muscles. Aim of Study:We aimed to investigate the concentric torque, total work and average power of knee muscles (quadriceps and hamstring) and functional status in OA patients in comparison with a matched control group.Patients and Methods: This cross-sectional study included patients with grade II knee OA diagnosed clinically according to the American College of Rheumatology (ACR) criteria and who had radiographic evidence of grade I or II tibiofemoral OA as judged by the Kellgren and Lawrence scale and 30 matched healthy individuals. Pain, stiffness, and physical function were assessed using visual analogue scale (VAS), Western Ontario and McMaster University Arthritis Index (WOMAC) and timed walking test. Muscle strength was measured using a computer-driven isokinetic dynamometer. The isokinetic variables used in the statistical analysis were peak torque, total work, and average power.Results: This study was conducted on thirty patients (21 females and 9 males) with mean age 44.967±4.238 diagnosed as knee osteoarthritis and 30 matched healthy subjects with mean age 46.067±3.741 and p-value was 0.362. The control group and the group of patients with knee OA were matched for gender and age. The independent t-test revealed statistically significant differences between the two groups with regard to isokinetic concentric peak torque, total work and average power at different angular velocities and for the timed walking test, as a measure of functional status. However, no significant difference in lower extremity joints' ROM and thigh girth were seen. Conclusion:Patients with knee OA, even in low grades and with minimum symptoms and signs, had muscle weakness and functional limitation in comparison with the matched healthy subjects.
