After the patient has been consented for a post-operative nerve block, physicians will provide a loading dose of Ropivacaine through the catheter. After one hour, the patient will receive their Ropivacaine infusions as per standard protocol.

After the patient has been consented for a post-operative nerve block, physicians will provide a loading dose of Normal Saline through the catheter. After one hour, the patient will receive their Ropivacaine infusions as per standard protocol.

Regional Anesthesia nerve blocks have become standard practice for several orthopedic surgeries for post-operative pain management, however concerns for compartment syndrome have prevented nerve blocks to become common practice for tibial plateau open reduction internal fixation pain management. Interestingly, saphenous nerve blocks do not cover the sciatic nerve, allowing for pain management while reducing concerns that it may possibly mask compartment syndrome. Patients will receive ropivacaine through the catheter from the start of the nerve block.

Pain scores on a scale from 0 to 10 will be collected by the research staff for 1 hour following the post-operative block. Pain scores will also be collected by the nurses throughout the patient's stay.

Opioid medications recorded in opioid morphine equivalents will be recorded by the research staff for the first hour following the post-operative nerve block. Opioid medications will be collected by the nurses throughout the patient's stay.

The patient's length of stay in the hospital will be collected by the research staff following the patient's discharge.
