Surgical excisional debridement is the mainstay of management in septic arthritis with necessary decompression, lavage, debridement, and partial synovectomy. However, there has been considerable debate over the optimal modality. Most surgeons perform an open arthrotomy or arthroscopic debridement, although serial aspiration can be considered as an option in very limited circumstances with patients who cannot tolerate surgery. While open arthrotomy has been often utilized, there has been an increasing number of proponents for arthroscopic treatment citing lower re-infection rates and better functional outcomes. However, there has been a lack of well-designed prospective studies comparing surgical treatment modalities for native knee septic arthritis. The goals of this present study are to determine if arthroscopic management of septic arthritis in the native knee resulted in a lower number of surgeries and a shorter length of stay compared to open arthrotomy. Secondary outcomes included differences in postoperative pain and improvements in Lysholm knee scores.

Number of surgeries to obtain lasting clinical resolution
The total number of surgeries performed during initial admission in order to obtain appropriate clinical response and resultant discharge on outpatient antibiotics.
Time frame: Through time period of initial admission (days; expected under 14 days)
Hospital length of stay
The total number of days in which the patient is initially admitted in order to obtain appropriate clinical response and resultant discharge on outpatient antibiotics.
Time frame: Through time period of initial admission (days; expected under 14 days)
Post Operative Pain Scores
Daily morning and afternoon visual analogue scale reported by nursing staff. This value is reported on a scale of 0-10; a score of 0 indicates no pain while 10 indicates unbearable pain
Time frame: Through time period of initial admission (days; expected under 14 days)
Post Operative Opioid Use
All patients will have post operative pain medications which are to be utilized in a step wise manner for treating their pain. For example, if they are in minimal pain they will be given tylenol whereas unbearable pain will be treated with opioid analgesics. The average total post-operative opioid usage during initial admission will be reported as total morphine milligram equivalent.
Time frame: Through time period of initial admission (days; expected under 14 days)
Lysholm Knee Scale
The Lysholm score is a 100-point scoring system for examining a patient's knee-specific symptoms including mechanical locking, instability, pain, swelling, stair climbing, and squatting. The scoring is between 0-100 points. A score of \<65 indicates poor knee function, 65-83 indicates fair knee function, 84-94 indicates a fair outcome, and 95-100 indicates excellent knee function. This scoring system will be obtained at 2 week, 6 week, and 3 months.
Time frame: Through anticipated follow up period of 3 month post operative appointment.
