Arthroscopy Association of Canada Position Statement on Opioid Prescription After Arthroscopic Surgery.

Background: Despite the ongoing opioid epidemic, most patients are still prescribed a significant number of opioid medications for pain management after arthroscopic surgery. There is a need for consensus among orthopaedic surgeons and solutions to aid providers in analgesic strategies that reduce the use of opioid pain medications. Purpose: This position statement was developed with a comprehensive systematic review and meta-analysis of exclusively randomized controlled trials (RCTs) to synthesize the best available evidence for managing acute postoperative pain after arthroscopic surgery. Study Design: Position statement. Methods: The Embase, MEDLINE, PubMed, Scopus, and Web of Science databases were searched from inception until August 10, 2022. Keywords included arthroscopy, opioids, analgesia, and pain, and associated variations. We included exclusively RCTs on adult patients to gather the best available evidence for managing acute postoperative pain after arthroscopic surgery. Patient characteristics, pain, and opioid data were extracted, data were analyzed, and trial bias was evaluated. Results: A total of 21 RCTs were identified related to the prescription of opioid-sparing pain medication after arthroscopic surgery. The following recommendations regarding noninvasive, postoperative pain management strategies were made: (1) multimodal oral nonopioid analgesic regimens-including at least 1 of acetaminophen-a nonsteroidal anti-inflammatory drug-can significantly reduce opioid consumption with no change in pain scores; (2) cryotherapy is likely to help with pain management, although the evidence on the optimal method of application (continuous-flow vs ice pack application) is unclear; (3) and (4) limited RCT evidence supports the efficacy of transcutaneous electrical nerve stimulation and relaxation exercises in reducing opioid consumption after arthroscopy; and (5) limited RCT evidence exists against the efficacy of transdermal lidocaine patches in reducing opioid consumption. Conclusion: A range of nonopioid strategies exist that can reduce postarthroscopic procedural opioid consumption with equivalent vocal pain outcomes. Optimal strategies include multimodal analgesia with education and restricted/reduced opioid prescription.

Antibiotic Cement-Coated interlocking Intramedullary Nails in the Treatment of Septic Complex Lower Extremity Reconstruction; A Retrospective Analysis with Two year Minimum Follow up.

Background: To report on our experience with antibiotic cement coated interlocking intramedullary nails (ACC-IMNs) for limb salvage in septic complex lower extremity reconstruction with a minimum of 2-year follow up. Methods: We retrospectively reviewed the records of all consecutive patients who underwent a limb salvage procedure with ACC-IMNs. We reviewed patients' demographics, the preoperative infecting organism, and host type, time to bone union, complications, limb salvage rates, and infection control rates. Results: There were 28 patients with a mean age of 62 years (range 22-88). The mean follow up period was 40 months (range 28-84). The ACC-IMNs were used in 14 patients (50 %) to achieve knee fusion after failed revisions of infected total knee arthroplasty, in 8 patients (28%) for septic tibial nonunion, and in 6 patients (21%) with ankle fusion nonunions. Bony union/fusion was achieved in 87 % (21/24) of patients. The infection was controlled in 80% (21/26) of patients. Four out the five patients who had recurrent infection were type B hosts (p=0.63). The limb salvage rate was 89% (25/28). The overall complication rate was 32%. Conclusions: The use of ACC-IMNs was an effective treatment strategy and associated with high limb salvage and bone union rates. Furthermore, the infection recurrence rate was low. Knee fusion patients after failed TKA should be counseled preoperatively for a potential high complication rate.

Biomechanical and Functional Improvements Gained by Proximal Tibia Osteotomy Correction of Genu Varum in Patients with Knee Pain.

BACKGROUND: Mechanical axis malalignment contributes to abnormal forces across the knee joint. Genu varum, or increased medial mechanical axis deviation (MAD), increases force transmission and contact pressures to the medial compartment. With increasing MAD and femoral-tibial mechanical axis angle (MAA), contact forces within the medial or lateral compartment of the knee significantly increase with increasing deformity. This may lead to knee pain, further deformity, and medial compartment degenerative joint disease, which can interfere with participation in sports and diminish quality of life. PURPOSES/QUESTIONS: We sought to evaluate patients with knee pain with bilateral genu varum and determine the effect of bilateral proximal tibial osteotomies on knee biomechanics, deformity correction, and functional outcomes. METHODS: This was a single-center, prospective study of eight limbs in four patients. Consecutive patients presenting with knee pain and bilateral genu varum originating from the proximal tibia were included. All patients underwent staged bilateral proximal tibial osteotomies with gradual deformity correction with an external fixator. Subjects underwent a three-dimensional (3D) instrumented motion analysis during level walking. A 3D lower extremity model was built and bilateral knee frontal plane kinematics and kinetics during the stance phase of gait were determined. Radiographic analysis was performed including assessment of MAD, MAA, and medial proximal tibial angle (MPTA). Functional outcomes were assessed with the Knee Injury and Osteoarthritis Outcome Score (KOOS), the 36-item Short-Form Survey (SF-36), the Lower Limb Questionnaire (LLQ), and a visual analog scale (VAS) for pain. RESULTS: The average time in the external fixator for a single limb was 97 days. The average follow-up period was 310 days. All biomechanical outcomes significantly improved, including knee adduction angle (7.8° to 1.8°), knee adduction moments (first peak, - 0.450 to - 0.281 nm/kg, and second peak, - 0.381 to - 0.244 nm/kg), and knee adduction moment impulse (- 0.233 to - 0.150 nm s/kg). There was a significant improvement in MAA, MAD, and MPTA. All patients showed qualitative improvement in mean scores on VAS (11.8 to 0.0), LLQ (77 to 93), KOOS (64 to 84), and SF-36 (71 to 88). CONCLUSION: These findings suggest that bilateral proximal tibial osteotomy may be effective in improving knee biomechanics during gait and correcting mechanical alignment in patients with bilateral genu varum. Patients also demonstrated improvement in functional outcome scores. This technique should thus be considered in patients with varus knee osteoarthritis in the setting of genu varum to alleviate symptoms and potentially decrease further clinical deterioration.

Return to Sports and Physical Activities After First Metatarsophalangeal Joint Arthrodesis in Young Patients.

BACKGROUND: Arthrodesis of the first metatarsophalangeal (MTP) joint has been shown to be effective in alleviating pain and correcting deformity in hallux rigidus. However, outcomes in specific sports and physical activities remain unclear. The aim of this study was to assess sports and physical activities in young patients following first MTP joint arthrodesis and to compare these results with clinical outcomes. METHODS: Patients between ages 18 and 55 years who underwent MTP arthrodesis were identified by review of a prospective registry. Fifty of 73 eligible patients (68%) were reached for follow-up at a mean of 5.1 (range, 2.2-10.2) years with a mean age at surgery of 49.7 (range, 23-55) years. Physical activity was evaluated with a previously developed sports-specific, patient-administered questionnaire. Clinical outcomes were evaluated with the Foot and Ankle Outcome Score (FAOS). RESULTS: Patients participated in 22 different sports and physical activities. The most common were walking, biking, weightlifting, swimming, running, and golf. Compared to preoperatively, patients rated 27.4% of activities as less difficult, 51.2% as the same, and 21.4% as more difficult. Patients returned to 44.6% of preoperative physical activities in less than 6 months and reached their maximal level of participation in 88.6% of physical activities. Ninety-six percent of patients (48/50) were satisfied with the procedure regarding return to sports and physical activities. Improvements in the FAOS Symptoms subscore were associated with increased postoperative running and walking duration, and improvements in FAOS Pain subscores were associated with greater patient satisfaction. CONCLUSION: Patients were able to participate in a wide variety of sports and physical activities postoperatively. Some patients reported increased difficulty, but were nonetheless satisfied with the procedure regarding physical activity participation. These findings suggest that first MTP joint arthrodesis is a reasonable option in young, active patients, and may be used to guide postoperative expectations.

Ankle Arthroscopy for Diagnosis of Full-thickness Talar Cartilage Lesions in the Setting of Acute Ankle Fractures.

PURPOSE: To delineate the prevalence of chondral lesions, in particular full-thickness talar dome lesions, with concurrent arthroscopy in acute ankle fracture open reduction-internal fixation (ORIF) and evaluate the impact on clinical outcomes. METHODS: We conducted a retrospective chart review of prospectively collected registry data at our institution from 2012 to 2016. Consecutive patients who underwent acute ankle fracture ORIF with concurrent arthroscopy were identified. Charts were reviewed to determine the prevalence and grade of chondral lesions, fracture type, and associated factors. Clinical outcomes with a minimum of 1 year of follow-up were assessed using the Foot and Ankle Outcome Score. RESULTS: The study included 116 consecutive patients undergoing acute ankle fracture ORIF with concurrent arthroscopy. A chondral lesion was identified in 78% (90 of 116). A full-thickness talar dome chondral lesion was identified in 43% of these patients (39 of 90). Patient age was a significant predictor, with patients younger than 30 years being less likely to have a chondral injury than those aged 30 years or older (59% vs 85%, P = .0077). Of the patients who sustained a dislocation at the time of injury, 100% had a chondral lesion (P = .039). Patients with complete syndesmosis disruption and instability were also more likely to have a chondral lesion (96% vs 73%, P = .013). Patients with chondral lesions had statistically significantly worse clinical outcomes than those without them (Foot and Ankle Outcome Score, 81.2 vs 92.1; P = .009). CONCLUSIONS: Ankle arthroscopy performed concomitantly with ankle ORIF is a useful tool in diagnosing chondral injuries. Chondral lesions are common with ankle fractures. An ankle with a dislocation at presentation or a syndesmotic injury may be more likely to present with a chondral lesion and should thus prompt evaluation. The presence of a talar chondral injury may be associated with a negative impact on clinical outcomes. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Intraoperative skull-femoral traction in posterior spinal arthrodesis for adolescent idiopathic scoliosis: the impact on perioperative outcomes and health resource utilization.

STUDY DESIGN: Retrospective, single-center cohort study. OBJECTIVE: To study how the systematic use of intraoperative skull-femoral traction (IOSFT) in posterior arthrodesis for adolescent idiopathic scoliosis impacts perioperative outcomes and health resource utilization. SUMMARY OF BACKGROUND DATA: Large scoliosis curves have been associated with increased morbidity and utilization of health resources. When used with reliable neurophysiological monitoring, IOSFT has shown to be safe and to reduce curve magnitude intraoperatively. Thus, we hypothesized that the systematic use of IOSFT may contribute to reducing health resource utilization by reducing curve magnitudes intraoperatively. METHODS: Seventy-three consecutive patients with adolescent idiopathic scoliosis who underwent single-stage posterior spinal arthrodesis from 2008 to 2012 at a tertiary children's hospital were identified. Forty-five patients were operated with IOSFT (traction group) and 28 patients were operated without IOSFT (nontraction group). Outcome measures included operative time, calculated blood loss, blood transfusion requirement, traction-related complications, and cost comparisons. RESULTS: Operative time was 375.6 minutes for the traction group (P=0.0001) and 447.6 minutes for the nontraction group. Calculated blood loss was significantly less in the traction group (P=0.027). Thirty-three percent of patients in the traction group required blood transfusion compared with 64% of patients in the nontraction group (P=0.01, absolute risk reduction of 31%). There was no significant difference in curve magnitude correction (P=0.49). There were no significant complications with the use of traction. There was a significant reduction in cost per surgical procedure in the traction group (P=0.0003). CONCLUSION: The systematic use of IOSFT in posterior spinal arthrodesis for adolescent idiopathic scoliosis contributed to significant reductions in health resource utilization, with no added morbidity. Further research is warranted to investigate the generalizability of these findings. LEVEL OF EVIDENCE: 4.
