A broken scalpel blade tip: an unusual complication of knee arthroscopy

The case of a patient is presented in whom a No. 11 scalpel blade was inadvertently broken and embedded within the lateral femoral condyle during initial arthroscopic portal creation. After a thorough diagnostic arthroscopy and synovectomy to expose the distal femoral articular surface was unsuccessful, luoroscopy was performed to localize the blade fragment in orthogonal planes. The blade tip was eventually retrieved from its position below the surface of the cartilage. The details of the loss and recovery of the blade fragment reinforce that exceptional care must be taken and attention given during the creation of portals, particularly when resistance is encountered. Additionally, all instruments, especially scalpel blades, should be exam- ined carefully when removed from the knee joint.
