Obesity Increases Incidence of Knee Dislocations, finds Study

Knee DislocationsKnee pain is a common complaint that commonly affects middle-aged adults and older people. The knee joint is particularly susceptible to pain and damage as it takes the entire weight of the body. Typically, sudden knee pain occurs due to a ligament injury, torn cartilage, knee dislocation, ligament strain or sprains. On the other hand, overuse syndromes such as tendinitis and bursitis as well as obesity, joint inflammation, arthritis, and other medical conditions can also affect the knee joint. Reliable pain management centers in Brooklyn, NYC offer effective treatment for both acute and chronic pain. Knee pain treatment can improve the patient’s mobility and functionality and improve their quality of life.

A new study reports that excess body weight can cause dislocation of the knee and may even lead to a complication that result in amputation of your leg. The study, published in the Journal of Orthopaedic Trauma, attributes a surge in dislocated knees to the United States obesity epidemic.

In addition to being prone to knee dislocation, the researchers found that obese people are more likely than normal-weight individuals to develop blood vessel damage that can lead to amputations. In most cases, knee dislocations happen when the patella or kneecap slips out of its normal position, which could be the result of intense exercise, trauma or physically challenging work. However, for obese people, knee dislocations occur due to trauma or excessive force and strain from carrying excessive bodyweight. As part of the study, researchers examined more than 19,000 knee dislocations from 2000 to 2012. This data included 2,300 injuries sustained by overweight and obese people. The research findings are as follows:

  • Over the study period, it was found that obese or morbidly obese patients made up an increasing share of knee dislocation patients. The proportion of patients hospitalized with knee dislocations who were also obese rose from 8 percent at the start of the study period in 2000 to 19 percent towards the end of the study in 2012.
  • Vascular injury is a severe complication because if undiscovered and untreated, it can lead to amputation of the leg. In total, about 1,075 patients, or about 6 percent, had vascular injuries during the study.
  • When compared to non-obese patients, researchers found that the chances of vascular injury during a knee dislocation were twice as high among obese or morbidly obese patients. Patients with less extreme obesity were 77 percent more likely to have vascular injury than non-obese individuals.
  • Typically, obese patients had longer and more costly hospital stays than non-obese people. The average hospitalization costs were $131,478 for vascular injury cases when compared to $60,241 for patients without vascular damage.
  • A total of 2 percent of obese patients had amputations.
  • Patients with a vascular injury were hospitalized for around 15 days when compared to only 7 days for those without the injury.

The results of the study indicate the key role of obesity in directly causing knee dislocations or vascular injuries. Maintaining an ideal weight or reducing extra kilos (if overweight) is an ideal way to avoid or prevent these issues of knee dislocations and subsequent vascular injury. Reliable multi-specialty healthcare centers in Brooklyn, NY offers effective weight loss programs that to help people maintain a healthy weight. As the study shows, losing weight is also important to offset extra pressure on weight-bearing joints. Pain management doctors at these centers also help patients choose the ideal work-out program for their needs. Low-impact exercises (that allow movement within the limits of pain) such as walking, swimming and water aerobics are ideal options for people with knee problems.
