The Minimally Invasive Posterior Approach: A Novel Technique for Shrapnel Removal in the Knee.

Retained periarticular missiles are usually overlooked, though they could lead to several delayed complications, which include infection, mechanical symptoms, synovitis due to lead particle deposition, lead arthropathy, and systemic lead poisoning. Retrieval of this shrapnel could be open or arthroscopic. The study reports a successful retrieval of retained periarticular shrapnel from the posterior compartment of the knee using the minimally invasive posterior approach. It presents the current literature review regarding this approach and various modifications. In conclusion, the minimally invasive posterior approach is a very good option for retrieving retained shrapnel from the posterior compartment of the knee. It offers good exposure, is relatively safe, and leaves a small scar, but it requires some learning to use efficiently.
