Implementing motor imagery practice into the course of physical therapy enhanced various physical outcomes during acute postoperative recovery after total knee arthroplasty. According to this pilot study, motor imagery might be relevant to promote motor relearning and recovery after total knee arthroplasty.Partial effect-sizes should be conducted in the future. Implications for rehabilitation Adding motor imagery to physical therapy sessions during the acute period following total knee arthroplasty: • Enhances quadriceps strength. • Alleviates pain. • Enhances range of motion. • Does not have any effect on basic functional mobility. • Does not have any effect on knee girth.
MI intervention seems to alleviate pain and enhance mobility, this is probably due to changes in muscle control and consequently in joint amplitude. MI might contribute to postpone or even protect from passing to stage III that may require surgery. Implications for Rehabilitation Adding motor imagery training to classical physical therapy in a stage II impingement syndrome: Helps in alleviating pain Enhances shoulder mobility Motor imagery is a valuable technique that can be used as a preventive tool before the stage III of the impingement syndrome.
During revision total knee arthroplasty, the joint line is frequently malpositioned, due to the disappearance of the anatomical landmarks following previous interventions. This leads to decreased clinical outcome and increased risk of re-intervention. Many methods have been proposed to restore the joint line, but none of them has shown itself to be reliable. We describe an accurate and precise method to localize the exact position of the joint line which guarantees a better clinical knee score. The adductor tubercle (AT) is recognized to be the most reliable landmark used to localize the knee joint line (JL). The distance from the AT to the JL on antero-posterior radiographs (ATJL) and the femoral diameter (FD) on true lateral views were measured on 200 randomly selected normal knees. These measurements were tested for intra- and inter-observer differences. Then, the relationship between these two measurements was studied. A significant correlation and linear regression between FD and ATJL was found (p < 0.001), making the adductor tubercle a valid landmark to accurately position the prosthetic joint within 4 mm from the normal position. No significant difference was noted in the intra and inter-observer measurements (F test not significant). Sex was found to be an intervening variable (p ˂ 0.001). The correlation and regression between ATJL and FD had to be adjusted accordingly. Once the ATJL was determined preoperatively, the JL level is found during surgery by using a caliper that is held on the easily palpable AT. Knowing the femoral diameter, we can easily locate the joint line level surgically, using the adductor tubercle as a landmark. This method leads to better clinical outcomes and a reduced risk of re-intervention following revision total knee arthroplasty.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
