Case:Klippel-Trénaunay syndrome (KTS) carries manifestations including skeletal dysplasia and prominent vascular malformations. This report details a case of hip dysplasia in the setting of KTS treated with total hip arthroplasty (THA) requiring preoperative embolization, intraoperative angiography for placement of an iliac artery occlusive balloon, and modular hip arthroplasty components for femoral and acetabular dysplasia. Perioperatively, the patient rehabilitated well and was walking painlessly and unassisted at 3 and 12 months postoperatively.Conclusion:Successful THA for dysplasia and degenerative changes associated with KTS is possible but requires a complex multidisciplinary perioperative approach.

Background: Limited studies have assessed the impact of state regulations on opioid prescribing patterns for patients undergoing total knee arthroplasty (TKA). This study evaluates how Florida House Bill 21 (FL-HB21) affected postoperative opioid prescribing for patients after TKA. Methods: Institutional review board approval was obtained to retrospectively review all patients who underwent TKA during 3 months of 2017 (pre-law) and 2018 (post-law) by five arthroplasty surgeons in Florida. Prescribed opioid quantity in morphine milligram equivalents (MME), quantity of refills, and number of prescribers were recorded for each patient's 90-day postsurgical episode. The differences between pre-law and post-law prescription data and short-term postoperative pain levels were compared. Results: The average total MME was notably reduced by over 30% for all time periods for the post-law group. The average MME per patient decreased by 169 MME at the time of discharge, by 245 MME during subsequent postoperative visits, and by 414 MME for the 90-day postsurgical episode (P , 0.001 for all). The quantity of refills was unchanged (1.6 vs. 1.6, P = 0.885). The total number of prescribers per patient for the 90-day postsurgical episode was unchanged (1.31 vs. 1.24 prescribers/patient, P = 0.16). Postoperative pain levels were similar at discharge (3.6 pre-law vs. 3.3 post-law, P = 0.272). Discussion: Restrictive opioid legislation was associated with notably reduced postoperative opioid (MME) prescribed per patient after TKA at the time of discharge and for the entire 90-day postsurgical episode. There was no increase in the number of prescribers or refills required by patients.
