Patient Q&A Section

What is 3d knee kinematics?

"Comparison of the knee kinematics of the knee flexion and extension during gait between healthy individuals and knee osteoarthritic individuals reveal significant differences in the knee kinematics; these differences can be attributed to the variations in the knee kinematics before and during gait in both groups and the joint angles during gait were similar in both groups." - Anonymous Online Contributor

Can 3d knee kinematics be cured?

"3D imaging is feasible in both healthy subjects and patients with degenerative knee joints. Using this technique, we are working on potential treatment plans for osteoarthritis with different knee biomechanics." - Anonymous Online Contributor

Unverified Answer

How many people get 3d knee kinematics a year in the United States?

"The incidence of 3D knee kinematics is steadily increasing, although the majority of studies concerning it are of low sample size and methodological quality. The prevalence of moderate/severe knee pain associated with the usage of a 3D-instrument in a sports setting warrants further study." - Anonymous Online Contributor

Unverified Answer

What causes 3d knee kinematics?

"The knee kinematics and cartilage degeneration are associated to the type of loading. This is supported by the kinematics pattern with increased medial and lateral compressive loading. It is not possible to identify the specific cause of knees kinematics because loading is complicated to define. Furthermore the knee biomechanics are likely to change the way the tissue heals, however a more accurate definition can be made with the type of loads and a longitudinal or cadaveric study can accurately answer the question." - Anonymous Online Contributor

What are common treatments for 3d knee kinematics?

"Results from a recent paper of the study indicate that patients can have minimal stiffness and pain after surgery. Patients that use braces and use knee flexors, or knee extensors, for 30 minutes or more are able to maintain normal knee kinematics. The patient can not maintain normal knee kinematics when using the knee flexor but when using the knee extensor. With surgery being the most common treatment, patients with knee injuries can also have normal knee kinematics. The study results suggest that patients should not be relying on braces or devices to maintain normal knee kinematics and that they will usually have normal knee kinematics after surgery." - Anonymous Online Contributor

What are the signs of 3d knee kinematics?

"3d knee kinematics measured during gait and stair descend are sensitive to knee pain/functional changes in adults. The majority of this sample met or exceeded the normative recommendation for minimum knee range of motion for the purpose of knee injury prevention." - Anonymous Online Contributor

Unverified Answer

Has 3d knee kinematic assessment under local anesthesia proven to be more effective than a placebo?

"3D kinematic assessments under local anesthesia provide significant results, better than with local anesthesia or placebo. With experience in the evaluation of the knee in the general population, these results provide clinicians with a benchmark." - Anonymous Online Contributor

Unverified Answer

What are the common side effects of 3d knee kinematic assessment under local anesthesia?

"Side effects of 3D knee kinematic assessment under local anesthesia are limited to moderate to transient pain during the procedure and early recovery phase and usually resolve within 7 days after the 3D measurement. These observations have practical implications for the feasibility and utility of the use of 3D knee kinematic assessment under local anesthesia for the prediction of knee osteoarthritis. Moreover, 3d knee kinematic assessment under local anesthesia with a portable system could be a useful adjunct in functional knee exams that integrates both radiographic (MRI and stress radiography) and 3D kinematic measurements." - Anonymous Online Contributor

What is the latest research for 3d knee kinematics?

"We found a recent body of research that has been very relevant, which includes [anterior cruciate ligament reconstruction with a hamstring graft in patients with knee instability following an anterior cruciate ligament tear with an anterior laxity ≥ 4 cm, and knee anteroposterior rotational laxity ≥ 20°.] You can find more studies published by using Power(3DK_kine_lax), which allows you to search studies tailored to your condition, treatment, environment, and ideal treatment." - Anonymous Online Contributor

Unverified Answer

Have there been other clinical trials involving 3d knee kinematic assessment under local anesthesia?

"Clinic directors' recommendation for the clinical use of local anesthesia as the sole anesthetic option is reasonable with regards to patient tolerance and safety. Therefore, 3D intraoperative knee kinematic evaluation with local anesthesia could represent a valid alternative to general anesthesia and could enhance the performance of orthopedic surgery under local anesthesia." - Anonymous Online Contributor

Unverified Answer

What does 3d knee kinematic assessment under local anesthesia usually treat?

"Recent findings of this study demonstrated no evidence that anesthesia and/or immobilization significantly affect the knee extension and flexion angles in the seated knee position. The kinematic parameters obtained from the 3D kinematic analysis do not provide valuable information about the knee biomechanical properties that may facilitate orthopedic or rehabilitative intervention." - Anonymous Online Contributor

Unverified Answer

What are the latest developments in 3d knee kinematic assessment under local anesthesia for therapeutic use?

"The study suggests the use of the 3D knee extension in determining the knee flexion angle to improve the visualization of the knee joint during local knee anesthetic injection. Furthermore, the combination of a 3D knee angle and a 3D knee flexion angle has proven to enhance the 3D knee visualization." - Anonymous Online Contributor
