RESUMO
PURPOSE: Injectable collagenase Clostridium histolyticum has been an effective and well-tolerated nonsurgical treatment option for the management of Dupuytren contracture of the hand. The purpose of this study was to determine the efficacy of collagenase injection and adverse event rate in patients who had undergone previous collagenase treatment. METHODS: A retrospective chart review was performed on 332 patients treated with collagenase injection for Dupuytren contracture by three fellowship-trained hand surgeons at a single institution from 2009 to 2019. Fifty-nine joints in 45 patients underwent repeat collagenase therapy for recurrent contracture in the same digit. Pretreatment and posttreatment total metacarpophalangeal and proximal interphalangeal joint flexion contractures were recorded, with complete correction defined as <5° residual digital flexion contracture. Postmanipulation skin tears and adverse events were recorded. A comparison was made between average contracture improvement after initial collagenase injection and that after repeat injection. RESULTS: Forty-five patients with an average duration of 30 months (range, 6-73 months) between initial and repeat collagenase therapies were identified. The mean improvement after first collagenase injection was 45° ± 24° (39° for metacarpophalangeal joint and 50° for proximal interphalangeal joint) compared with a mean improvement of 43° ± 23° (41° for metacarpophalangeal joint and 44° for proximal interphalangeal joint) after second injection. Although similar complete correction rates and skin tear rates (32.2 % for initial and 30.5% for repeat) were observed between initial (80%) and repeat injections (73%), the occurrence of adverse events was 3 times higher (3.4% for initial and 10.2% for repeat) in the latter group. CONCLUSIONS: Collagenase treatment of Dupuytren contracture yields effective total flexion contracture correction. Repeat collagenase treatment of previously treated digits yields similar deformity correction and complete correction rates but a higher incidence of adverse events. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
RESUMO
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. LEVEL OF EVIDENCE: Level III retrospective cohort.

BACKGROUND: No evidence-based guidelines exist for the perioperative use of clopidogrel in elective hip and knee arthroplasty patients. This study compares the preoperative, intraoperative, and postoperative outcomes of total hip and knee arthroplasty in patients maintained on clopidogrel and with patients whose clopidogrel was held before surgery. METHODS: We retrospectively identified 158 patients taking clopidogrel before undergoing elective total hip or knee arthroplasty. Patients were stratified for having clopidogrel held or continued, based on the interval between latest dose and date of surgery. The primary end points were receipt of transfusion and readmission within 90 days of surgery. Secondary end points were the incidence of complications such as bleeding, infection, re-operation, and major cardiac or neurologic events such as myocardial infarction or stroke during the 90-day postoperative period. RESULTS: The two cohorts had similar demographics. Patients who continued clopidogrel were more likely to receive a blood transfusion postoperatively (9.1% vs 0%, P = .005), but there was no difference in wound drainage (P = .65), wound infection (P = .24), readmission (P = .74), major complications (P = .64), length of stay (P = .70), or mortality (P = .42). Patients who continued clopidogrel before surgery were more likely to have received general anesthesia (P < .001) per anesthesia protocol, however, three such patients did receive spinal anesthesia without any complications. With cementless implants, blood loss was not different between clopidogrel groups. CONCLUSION: Patients undergoing elective total hip and knee arthroplasty may be safely maintained on clopidogrel without an increased risk of wound complications, infections, length of stay, readmission, reoperation, major medical complications, or mortality. Further prospective research is warranted to confirm the effects of continuing clopidogrel in patients undergoing elective hip and knee arthroplasty.

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: The use of highly conforming polyethylene tibial inserts in cruciate-retaining total knee arthroplasty (TKA) often requires posterior cruciate ligament (PCL) release/sacrifice for balancing (CS TKA). The CS TKA relies on the posterior capsule, collateral ligaments, and articular conformity without a cam or post to achieve stability. Using prospectively collected data we compared clinical outcomes of CS TKA to posterior-stabilized (PS) TKA utilizing a contemporary TKA system. METHODS: Sixty-nine consecutive CS TKAs were compared to 45 consecutive PS TKAs at 2-year minimum follow-up. CS knees were balanced with the PCL released. Preoperative/postoperative range of motion (ROM), Knee Society Scores (KSS), stair function, and squatting ROM were analyzed. RESULTS: At minimum 2-year follow up, CS and PS TKA demonstrated significant improvement in ROM (P < .001), KSS (Pain, P < .001; Function, P < .001), and KSS stair function (P < .001), with no revisions. There was no difference in preoperative to postoperative improvements for passive knee ROM (10° (0°-20°) vs 13° (5°-25°); P = .16), KSS Pain (34 (21-42) vs 38 (24-46); P = .22), KSS Function (35 (30-50) vs 35 (18-50); P = .34), and KSS stair function (10 (10-20) vs 10 (0-20); P = .37) for CS and PS TKA, respectively. CS TKA had higher squatting ROM (P = .02) at minimum 2-year follow-up compared to PS TKA. CONCLUSION: Both PS and CS TKA provided significant improvement in clinical outcomes, with no differences in passive ROM, KSS, or stair function postoperatively. Our data support that with proper articular conformity and balancing, cruciate-retaining TKA in a PCL-deficient knee (CS TKA) is appropriate. This may be design specific and further prospective randomized studies are needed to corroborate these findings.
