Knee injury
What symptoms can a loose body in the knee cause?
Doctor’s answer
A loose body may cause catching, sudden pain, clicking, restricted motion, or recurrent effusion. When symptoms frequently affect walking or sport, imaging is usually needed. Some patients benefit from arthroscopic removal and treatment of the underlying cartilage or synovial problem.

Why should rehabilitation after sports medicine surgery not follow time alone?
A timeline gives only a rough stage. Progress is determined by pain, swelling, range of motion, strength, movement control, tissue healing, and what was done during surgery. Moving too quickly may increase failure risk; moving too slowly may lead to stiffness and loss of function.
Can long-term pain after a sports injury become chronic pain?
Yes. Persistent pain may relate to incomplete tissue recovery, loading too soon, joint stiffness, strength deficits, sleep or mood issues, and pain sensitisation. Treatment should reassess the diagnosis and combine rehabilitation, load management, and pain education.
Do flat feet need corrective insoles?
Painless flat feet usually need no specific treatment. If sport repeatedly causes arch, ankle, knee, or lower-leg pain, orthoses, foot and ankle strengthening, calf flexibility, and running-load review may help. Rigid flatfoot or new one-sided collapse requires further assessment.
