Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: penicillins / lipitor attending: chief complaint: 72m s/p l tka revision with left knee weakness and drainage major surgical or invasive procedure: : i&d and vac @ 125, retained implant : i&d and vac at 125, retained implant : to place ivc filter : i&d, vac at 125, retained implant : i&d, liner exchange, medial gastroc flap, skin graft history of present illness: this is a 72 year old male with a medical history significant for dm2, htn, hld who recently () underwent a complex revision left total knee replacement (with hinged knee prosthesis) for a failed primary left total knee arthroplasty. he was admitted on for a failed total knee replacement and underwent a planned revision left total knee replacement which was converted to a resection arthroplasty of all components with extensive synovectomy. his course was complicated by hypotension related to blood loss from first surgery which required an icu stay and small pe diagnosed for which he was started on coumarin. he was then taken back to the or on for the complex revision of the left tkr as above. he was monitored in the icu after that operation for unclear reasons. he was discharged in a stable condition on his home medications. he reports that at the time of discharge he was having a lot of pain and some serosanguineous drainage from his knee. he was initially able to walk with a walker but over the course of the weeks he was slowly unable to walk. about 1 week prior to admit he developed fevers/chills and some redness and swelling of the knee. the swelling increased to the point where he could not move the knee at all. that is what ultimately prompted him to come to the ed. he then presented to the ed with bloody drainage from his left knee weakness and chills. an xr of the knee on revealed some gas in the subcutaneous tissue and joint space which was concerning for an infection. his wbc count was initially normal but increased to 17 on . an esr was elevated at 95 and a crp was 200.1. the knee was tapped on and the cell count revealed wbc (95% polys). the gram stain revealed 1+ polys. of note his cr was also elevated from last admit at 1.4 up from baseline of 1. past medical history: t2dm htn hepatitis b (carrier) hyperlipidemia gout nephrolithiasis osteoarthritis (r hip) allergic rhinitis sciatica l knee replacement s/p screw removal in l

the patient was admitted to the orthopaedic surgery service on with the complaint of meft knee weakness and drainage. he noted that while at rehab he became progressively unable to extend his knee and noticed reddness and dranage along the inferior aspect of his incision. the diagnosis of a patellar tendon rupture was made after admission. there was an area of erythema located over the distal end of his incision that became progressive over his first 2 days of admission. he to spike fevers and subsequently had his knee tapped which revealed 13,000wbc and a culture that eventually became positve for mssa. he also had a fever spike as high as 104.3 and had a positive blood culture for mssa. he was taken to the operating room on for a left knee i&d and a vac dressing placement. he was once again taken to the or on for repeat i+d and vac change. all implats were retained during these procedures. he was left intubated following his second procedure for intermittnet hypotension and respiratory distress. he was extubated in the icu without issue. he received an ivc filter on and was taken back to the or for a repeat i+d and vac change on with retaiend hardware. he was taken back to the or for definitive repair on in combination with plastic surgery for a repeat i+d, liner exchange, medial gastrocnemius flap and split thicknedd skin grafting. he had a vac drain placed as a bolster and drain in place. he was kept on bedrest for 5 days following this procedure. he had a short stay in the icu for monitoring but was subsequently transferred to the floor in stable condition following this procedure. please see separately dictated operative reports for details. the patient initially received vancomycin until culture speciation and was subsequently trnasitioned to ancef and rifampin per infectios disease who were consulted regarding his care. the patient received several traunsfusions of prbc and ffp for falling hematocrit and inr reversal respectively. he was anticoagulated on therapeutic lovenox during his stay for known prior pulmonary embolus. otherwise, pain was initially controlled with a pca followed by a transition to oral pain medications on pod#1. at the time of discharge the patient was tolerating a regular diet and feeling well. the patient was afebrile with stable vital signs. the patient's hematocrit was acceptable and pain was adequately controlled on an oral regimen. the operative extremity was neurovascularly intact and the wound was benign. at time of discharge, patient was deemed stable for safe discharge to rehab. the patient's weight-bearing status is touch down weight bearing as tolerated on the operative extremity locked in extension. medications on admission: 1. warfarin 1 mg tablet sig: three (3) tablet po once daily at
