Knee dislocation is one of the most painful injuries. It is so severe that it needs immediate medical attention. Any athlete will tell you how excruciating the initial knee pain is, and thus immediate relief is the next logical thing. Dislocation occurs in the kneecap which rests in a groove at the end of the thigh bone. The kneecap rests in the groove when the knee is bent and supports the quadriceps muscles which stabilize the legs when extended.
How does it happen?
Dislocation of the knee occurs in two ways; partial dislocation—subluxation, and patella dislocation—when the kneecap/patella completely dislocates from its normal positioning. When such injury occurs, extreme knee-pain is usually reported, and a bone specialist should immediately attend to it.
Causes of Knee Dislocation
Traumatic incidents usually cause patella dislocation. But there are some risk factors which expose you to this condition. These include:
• Previous history of kneecap-dislocation
• Shallow lower thigh bone groove
• Weak quadriceps inner muscles
Kneecap-dislocation is quiet common in teenagers who are athletes.
Symptoms and Complaints
• Swelling at the knee
• Feeling that you can not support your weight
• Pain especially when supporting your weight and while straightening the leg
• The kneecap is displaced and is visually seen on the outside
• An easily movable kneecap
What should you do in Case of a Dislocated Knee?
After having a kneecap dislocation and no correction seems viable, call an ambulance while keeping your leg still. You may enlist help from someone to help lift your foot and straighten your knee. He/she will realign your kneecap and note that minimal pain should occur. After the injury, an ice pack placed on the knee should suffice, at least, 10 to 15 minutes a day.
Diagnosis and Treatment
A bone specialist looks for signs of dislocation, muscle and ligament damage. X-rays and MRI scans are typically done to ascertain diagnosis and extent of the injury on the patella. A variety of treatments exist. They are:
1. Patella relocation
As the phrase suggests, a bone-specialist relocates the patella to its initial position.
After patella relocation, most patients need a recommended six-week rehabilitation to avoid future dislocation. It would aim to reduce pain and discomfort, normalise joint range motion, improve kneecap alignment, improve agility and balance, minimise chances of re-dislocation , and re-strengthen lower limbs, in particular, the calves, pelvic muscles and the hip
Sometimes the damage to the ligaments, muscles, and the patella is so dire that one needs surgery for treatment instead of conventional methods.
After surgery, physiotherapy is a must for complete restoration of normal limb operations.
Prevention of Future Patella Dislocations
To avoid such injuries, one has to do a few things like observing proper exercising techniques and warming up before jogging to raise the body temperature. Treated patella dislocations have a knack of recurring, so it is imperative that you discuss with your physiotherapist and bone-specialist on the best treatment plan and rehabilitation regimen. It will decrease incidences of recurrences.
