Bacterial infection

Synonyms:purulent arthritis
Location of the greatest pain: Not clearly identifiable. Pain around the entire joint. Partial pain maximum above the inner femoral condyle.
PathologyCause:Bacterial knee inflammation either through direct germ introduction or in the context of a bacterial infection via the bloodstream.
Sources can be a chronic sinusitis or chronic dental root inflammation. Direct germ transfer can be caused by a puncture of the knee joint.
Age:Any age. Via the bloodstream (hematogenic especially in infants)
Gender:none
Accident:Possibly with opening of the knee joint or after an operation.
Type of pain: Stabbing, bright, burning.
Origin of pain: Mostly acute with rapid progression.
Pain occurrence:Constant pain, pain under stress.
External aspects: overheating, swelling, redness. Fever! Putride (purulent turbid) fluid during knee joint puncture.

Cruciate ligament injury

Synonyms in a broader sense: anterior cruciate ligament rupture, ACL rupture, cruciate ligament lesion, knee instability, cruciate ligament insufficiency, cruciate ligament rupture, cruciate ligament plastic surgery, anterior cruciate ligament
Location of the greatest pain: Not clearly identifiable. Pain around the entire joint.
PathologyCause: Tear of the anterior or posterior cruciate ligament
Age: Any age. Young, sporty active people.
Female footballers are particularly at risk.
Gender: No gender preference.
Accident: Adequate accident, usually with twisting of the knee joint. Combination injuries with involvement of other structures are possible, especially meniscus and external ligament.
Type of pain: Stabbing, bright.
Origin of pain: Acute, in connection with the accident.
Pain occurrence: Stress pain. Knee instability.
External aspects: Swelling. Functional limitation of the knee joint. Bloody fluid during knee joint puncture (haemarthrosis).

Pain on the inside of the knee

Pain on the inside of the knee can have various causes, the following are common: damage to the inner meniscus: In our knee we have two menisci, the inner and the outer meniscus, which are mainly used to repair irregularities in the knee and to absorb shocks. In young people, the menisci are still very resilient and flexible. Here, damage is most likely caused by an acute injury such as during sports.

Especially sports like tennis, soccer or skiing put a lot of strain on the menisci. With age, the elasticity of the menisci decreases and wear and tear occurs. This can cause damage to the menisci even with slight overstrain or sometimes even without the use of force.Since the inner meniscus is more firmly anchored in the knee and is not as mobile as the outer meniscus, injuries are more frequent here.

Acute injuries are often accompanied by joint swelling and pain on the inside of the knee, which is intensified by twisting and bending movements. In the case of meniscus damage due to wear and tear, the symptoms are not as clear-cut, but here, too, there is internal knee pain that increases steadily under stress and over time. Osteoarthritis on the inside of the knee: Osteoarthritis is a wear and tear of the joint that exceeds the normal level for the age group.

In particular in the case of a malposition of the legs, the so-called bow legs, excessive one-sided loading of the knee can lead to arthrosis on the inside of the knee, which also manifests itself through pain. Inflammation and tendon damage: Inflammation of the bursa, which occurs naturally in the knee, can also cause pain on the inside of the knee, as can injury to the tendon of the semimembranosus muscle, which is a flexor in the knee joint. Wrong footwear and a resulting foot malposition can also cause pain on the inside of the knee.
