my dad has been experiencing his knees locking when he walks up stairs lately. there's no pain or swelling, just sudden locking. he's been cycling regularly for the past 40 years with no prior medical issues or surgeries. could this be from a muscle tear or maybe because he doesn't walk much

It's possible, though not definitively, that the knee locking is due to a meniscal tear or another cartilage issue, or even a ligament injury, especially if he hasn't been walking much. However, since he's been cycling regularly, it's also possible that the knee locking is related to the activity itself, such as a patellofemoral pain syndrome or even just improper muscle balance. It's best to consult a doctor or physical therapist for a proper diagnosis and treatment plan.

Question

I've been diagnosed with grade 4 chondromalacia and a partial ACL tear can this be fully fixed with surgery or is physiotherapy enough to recover properly?

I had surgery in 2014 where they removed all stitches and put a metal rod in my leg. The operated area is dry now, but there's still a small hole where fluid leaks out sometimes. I can't walk or stretch properly because my leg feels stiff, and there's nerve pain. The fluid leakage stops and starts randomly what could be causing this and should I be worried?

Question

Four months ago on May 8th, I had an accident that broke the bone in my polio-affected leg. The doctor did surgery and inserted a rod from my thigh bone to the knee with screws. Now my bones are healing and I've started walking, but I can't bend my knee at all. I've been doing wax therapy and some exercises, but it's still really hard to bend. What treatment would help me get my knee movement back?
