Outcomes of the Nanoscopic Partial Meniscectomy Versus Standard Arthroscopic Partial Meniscectomy

Study Overview
=================
Brief Summary
-----------------
Standard arthroscopy has been the gold standard for treatment of meniscus tears since the 1980's. The purpose of this study is to analyze the clinical outcomes of using the smaller diameter Nanoscope for partial menisectomy. The authors hypothesize that the Nanoscopic partial menisectomy patients will have less pain and return function faster than standard arthroscopy.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Nanoscopic Partial Meniscectomy<br>This is the experimental group. patients will have a partial meniscectomy performed using the arthrex nanoscope | Procedure: Nanoscopic partial meniscectomy<br>* Patients will have a partial meniscectomy performed using the arthrex nanoscope and it will be compared to partial meniscectomy performed using standard arthroscopic equipment<br>|
| Active Comparator: Standard Partial Meniscectomy<br>Patients will have a partial meniscectomy performed using standard arthroscopic equipment which is the current gold standard | Procedure: Standard Partial Meniscectomy<br>* Patients will have partial meniscectomy performed using standard arthroscopic equipment<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functional Outcomes following partial meniscectomy: Knee Injury and Osteoarthritis Score | We will be looking at functional outcomes following partial meniscectomy with the nanoscope compared to standard arthroscopy by looking at Knee Injury and Osteoarthritis Score (O -100 with higher being patients doing better functionally) | 6 weeks | 
| Functional Outcomes Following Partial Meniscectomy: International Knee Documentation Committee Score | We will be looking at functional outcomes following partial meniscectomy with the nanoscope compared to standard arthroscopy by looking at the International Knee Documentation Committee Score (0-100 with higher being patients doing better functionally) | 6 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain: Visual Analog Pain Score | Pain following partial meniscectomy with the nanoscope compared to standard arthroscopy using Visual Analog Pain Score (0-10 with 0 being no pain and 10 being the worst pain) | 6 weeks | 
| Narcotic Medication Use | we will be looking at the amount of narcotic pain medication used following nanoscopic partial meniscectomy compared to standard arthroscopy | 24 hours | 
| Return to work | time to return to work following partial meniscectomy | 6 weeks |
