Measure
Single Portal Knee Arthroscopy
After randomization for each patient is complete, the website will document the name of the person who logged on to perform the randomization, the date and time of the log in, and the surgical group assignment for each patient. This randomization information will be forwarded to the operating room staff so that they can prepare for each study participant's surgical procedure. Patients in Group 1 will undergo knee arthroscopy using a single portal. The details of the surgical procedure for each study participant will be documented on the IKDC Surgical Documentation Form. Study participants in each group will return for standard post-operative follow-up visits at one week, 30 days, and three months. They will return to the clinic at six months and one year for study visits. Single Portal Knee Arthroscopy: Patients in Group 1 will undergo knee arthroscopy using a single portal.
Two Portal Knee Arthroscopy
Patients in Group 2 will undergo knee arthroscopy using two portals. The details of the surgical procedure for each study participant will be documented on the IKDC Surgical Documentation Form. Study participants in each group will return for standard post-operative follow-up visits at one week, 30 days, and three months. They will return to the clinic at six months and one year for study visits. Two Portal Knee Arthroscopy: Patients in Group 2 will undergo knee arthroscopy using two portals.

Baseline Characteristics

One subject from the Single Portal Knee Arthroscopy arm and two subjects from the Two Portal Knee Arthroscopy arm did not provide obesity information, which explains the discrepancy in the overall number of participants analyzed for this measure.
