Study strengths and limitations
KOA

During knee OA rehabilitation, applying progressively heavier loads is important to preventing muscular adaptations to the exercise (Muscle morphology is another parameter used to evaluate functional outcomes of training. Still, it was not used in our study due to the 4.2–13.0 MHz wide-band linear array scanning transducer head and the image analysis software available to our study group.BFR resistance exercise is employed by individuals with limited or incapacity of performing high-intensity resistance exercise, such as elderly (This study included a specific subgroup of KOA patients, which limits the generalization of our findings to other patient populations. Moreover, it focused on a specific degree of KOA (Kellgren and Lawrence grade II–III), which may also limit the generalizability of our results.
