Post-discharge clinic visits; n = 1959. Clinic visits after discharge for 1959 patients who followed up within the UWMC hospital system for each of the thirty days following discharge (including orthopaedic, primary care, and other subspecialty clinics). Blue bars represent the number of nonreadmitted patients seen in any clinic on that post-discharge day. Red bars represent number of readmitted patients seen in any clinic that day. (Data in Fig. 1 add to seventy-nine of the total 125 readmitted patients because remainder likely followed up with another, outside provider [see Discussion]).

Incidence of arthroplasty in patients with HIV/AIDS over time in the United States. The national estimates were calculated from the NIS with use of discharge weights. THA = total hip arthroplasty, and TKA = total knee arthroplasty.

A line graph showing the surgical site infection timeline of all infections (n = 78). Sixty-seven percent of surgical site infections were documented during the first thirty days and 90% were identified within the first six months following surgery.

Flowchart showing the study group selection. HgA1C = hemoglobin A1C.

Schematic block diagram illustrating the ACL Clinical Pathway with perioperative steps for patients and guidelines for providers. NMCSD = Naval Medical Center San Diego, ACLR = anterior cruciate ligament reconstruction, ASA = American Society of Anesthesiologists, d/c = discharge, OR = operating room, PT = physical therapy, rehab = rehabilitation, PACU = post-anesthesia care unit, POD = postoperative day, s/p = status post, H&P = history and physical, Rx = prescription, and abx = antibiotics.

Demonstration of the surgical technique on a bone model. An intramedullary Kirschner wire is passed through the fibular graft, and the graft-and-Kirschner-wire construct is used to fill the bone gap.

Postoperative cellulitis after total knee arthroplasty. Patients with a superficial skin infection are at increased risk of periprosthetic joint infection.

Flowchart of the Children’s Medical Center of Dallas guideline for the evaluation and treatment of suspected pediatric osetomyelitis. Abx = antibiotics, CRP = C-reactive protein, DVT = deep venous thrombosis, ESR = erythrocyte sedimentation rate, IV = intravenous, LE = lower extremity, MRI = magnetic resonance imaging, MRSA = methicillin-resistant Staphylococcus aureus, MRV = magnetic resonance venography, NPO = nil per os (nothing by mouth), PICC = peripherally inserted central catheter, SPE = septic pulmonary embolism, and TTWB = toe-touch weight-bearing.

Radiographs showing treatment of a large bone defect with the two-staged technique of bone-grafting. Fig. 1-A An antibiotic cement spacer stabilized with internal fixation after bone resection. Fig. 1-B Four weeks later, the spacer was removed and the granulation tissue cavity was filled with cancellous autograft bone. Fig. 1-C Newly formed bone two months after bone-grafting.

Fig. 1-A Receiver operator characteristic curves for cathelicidin LL-37 (area under the curve [AUC] = 0.875), human β-defensin (HBD)-2 (AUC = 0.640), and HBD-3 (AUC = 0.745) in synovial fluid. Optimal cutoffs that maximize the Youden index are indicated by solid dots. Fig. 1-B Receiver operator characteristic curves for combinations of cathelicidin LL-37 and interleukin (IL)-4 (AUC = 0.916), LL-37 and IL-6 (AUC = 0.895), HBD-3 and IL-4 (AUC = 0.972), and HBD-3 and IL-6 (AUC = 0.849) in synovial fluid according to logistic regression analysis. Optimal cutoffs that maximize the Youden index are indicated by solid dots.
