Case 1: How long does it take to recover from running knee pain?
[Patient's self-report]: My child is about to take the college entrance examination, but his 1 km long run is always unqualified. During this time, I practiced with him, probably because I was older, and after running twice, my knees began to hurt, and I didn't know when I would recover. That stinky boy, I don't accompany him, he's lazy, how can this work! Ask the doctor: How long does it take for the pain in the running knee to recover?
[Doctor's answer]: The recovery time of knee pain after running is related to the cause of pain. There are two main causes of knee pain after running: one is functional and the other is structural.
Functional – often refers to structural strains around the knee joint and dysfunction. The structures involved in this pain are mainly muscles and ligaments. Generally, through braking, rest, and even initial home therapy, a certain degree of relief can be obtained within 1-2 weeks.
Structural – This situation is often irreversible and takes a long time to fix. Because of the degeneration of joint cartilage, such as joint pain caused by patella carcinia, in the process of self-repair, the cartilage cannot be reversed to the pre-injured state, and can only be repaired by scars, forming fibrochondrite with poor elasticity. Pain may also occur more quickly during the next exercise.
If the knee pain caused by meniscal injury, if the meniscal injury is not treated, then the resulting pain cannot be eliminated, and can only be improved through symptomatic treatment, and even once some patients have 3 degrees of injury, they cannot fully return to normal, that is, in the subsequent process of running and exercise, there may be continuous pain.
Case 2: What is the pain in the knee of a young person when he bends?
【Patient's statement】: 28-year-old male, usually do not like sports. Last month the unit came with a new female colleague, very beautiful, and I started going to the gym to work out. But since last week, I suddenly felt pain on the right side of my knee, and my knee would hurt as soon as I bent. This symptom occurs occasionally, and the frequency of these two days is getting higher and higher. Ask the doctor: What is the pain of a young man's knee when he bends?
[Doctor's answer]: Young people's knees are painful when they are bent, and often the structures in the knee joint are damaged, including meniscal injuries, cartilage injuries, ligament injuries and so on.
Patients with meniscal injuries usually experience pain when going up and down stairs, especially when going up stairs, and the movement of going up stairs requires knee bending, accompanied by weight bearing, which will aggravate meniscus injury and cause pain.
Among the many causes of knee bending pain in young people, cartilage injuries are one of them, especially patella cartilage.
For example, some young white-collar workers usually rarely exercise, but suddenly go to the gym to exercise squats, 2-3 months will appear patella softening phenomenon, resulting in knee pain when the knee joint is bent, and it is more obvious when squatting and going downstairs.
Ligament injuries are often a history of trauma, and after injury, ligament fibers are broken, and ligament dysfunction causes joint instability. Over time, the joint degeneration will be accelerated, and the pain during the flexion and extension of the knee joint will occur.
In addition, there may be other causative factors that require the help of examinations and doctors to help diagnose.
