A dislocated knee refers to a kneecap that slips off the joint. This can happen due to trauma from a sudden force against the knee. It can also occur during sports if your foot is planted on the ground and you make a sudden, forceful, twisting motion of the knee. A dislocated knee may be relieved through rest, ice, compression, and elevation. In some cases, physical therapy or even surgery may be required, especially if the dislocation is accompanied by damage to surrounding ligaments or tendons.
Gout is a type of arthritis in which uric acid crystallizes in the joints, causing pain and inflammation. Although the joint of the big toe is a common spot for gout to strike, the joint of the knee may also be susceptible to this condition. Risk factors for this condition include a family history of gout, obesity, and the use of certain medications. A diet heavy in purine-rich meats and seafood can trigger an attack of gout. Additionally, sugary foods and beverages such as sodas or fruit juices can contribute to the accumulation of uric acid in the joints.
4. Baker’s Cyst
A Baker’s cyst is a swollen area that may develop behind the knee in response to trauma or injury. Following diagnosis, your physician may treat a Baker’s cyst by prescribing rest, ice, and elevation of the area. In addition, physical therapy, draining fluid from the cyst with a needle, or steroid injections may help treat this condition. According to the Cleveland Clinic, surgery is sometimes necessary in order to remove this fluid-filled sac.
