Knee locking refers to when the leg gets stuck in one position, making it impossible to bend or straighten it. It may only last a few seconds, it may last longer. It all depends on what is causing it. Most cases fall into one of two categories.
There is true locking caused by a mechanical block where something gets stuck inside the joint, preventing movement. This type most commonly occurs as you move the knee into full extension, i.e. towards being fully straight.
Secondly, there is pseudo locking, caused by severe pain which temporarily limits movement in any direction.
Unclear about the question. Although in the text is described that the locking is mechanical (due to loose bodies or meniscal and ACL tear) when usually the knee locks in flexion or the pseudo-locking, when the knee usually locks in extension, the logic of the question was demonstrated in a clear way. The common reason for pseudo-locking is patello-femoral pathology (degeneration of the articular surface of the patella or the trochlea or in rare conditions the existence of a thick plica, folding of the synovium). Nothing of all this is influenced by the diet, except if the amount of food that is consumed is excessive and is resulting to obesity. This is the only case that diet can influence the knee locking. Dietary habits can influence the uric acid and so the potential gouty synovial reaction and consequently arthritis, but this is another matter.
Dear
can you clarify your question
I don't know a relation between diet and knee locking, there is may be some relation with overweight or type of consumed food.
