The most common and significant complication associated with fractures or dislocations of the knee is: select one: a. total depletion of synovial fluid. b. neurovascular compromise. c. ligament and cartilage damage. d. internal bleeding and shock.

B. Neurovascular compromise

Explanation:

When a person fractures or dislocates their knee, the most significant complication that can arise is nerve damage. This can be known as neurovascular compromise.

While all the options are definitely concerns, neurovascular damage is the most significant problem caused by fractures.

If left unchecked, the patient can experience pain, parasthesia (not being able to feel their leg) and even paralysis (not being able to move their leg).
