Background: The anterior cruciate ligament (ACL) is the most commonly injured ligament in the knee. ACL reconstruction (ACLR) proves the standard for treating this injury. However, graft choice and method of fixation remain a heavily debated topic. This study investigates the following: bone-patellar tendon-bone (BPTB) vs. hamstring tendon (HT) autograft, single-bundle vs. double-bundle hamstring graft, and metal vs. bioabsorbable screws in ACLR., Methods: A systematic review was performed on PubMed and Google Scholar according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data were collected on patient demographics, complications, and functionality scores including International Knee Documentation Committee (IKDC) and Lysholm scores. A systematic review and meta-analysis were conducted with Review Manager. Outcome measurements were determined using forest plots with significant differences considered p < 0.05., Results: Twenty-five studies were included, accounting for 2,170 patients. No statistically significant difference was appreciated when comparing BPTB to hamstring autografts. Patients who received a double bundle HT autograft exhibited significantly superior outcomes in terms of revision (p = 0.05), failure (p = 0.002), normal pivot shift tests (p = 0.04), and normal IKDC (p = 0.008). When comparing screw types, bioabsorbable screws had a greater Lysholm score (p = 0.01) and lower failure rates for copolymer screws (p = 0.03)., Conclusion: Overall, the data collected suggested that BPTB and HT autografts display similar postoperative results. However, if an HT autograft is used, the data suggest a double-bundle graft improves both functionality and decreases the possible complications. Finally, bioabsorbable screws prove superior to metal screws when looking at both functionality and failure rates. Further research into the superior graft type is still needed., Level of Evidence: Level II.

Case: Combined medial and lateral patellar instability is exceptionally rare with only 3 reported cases to date. Here, we present the case of a 37-year-old White woman with multiple recurrent medial and lateral patellar instability. After failure of conservative care with bracing and therapy, she underwent surgical stabilization with medial and lateral allograft reconstruction., Conclusion: This case provides an example of the condition and successful surgical follow-up., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/B634)., (Copyright © 2021 by The Journal of Bone and Joint Surgery, Incorporated.)

Introduction: Opioids are widely used after orthopaedic procedures. Nonmedical opioid use is a growing public health issue., Methods: An anonymous online survey was distributed by e-mail to the orthopaedic societies of all 50 states and several large private practices to assess practicing orthopaedic surgeons' opioid prescribing practices., Results: A total of 555 orthopaedic surgeons practicing in 37 states responded. The most commonly prescribed opioid for both teenagers and adults was hydrocodone/acetaminophen. Of note, 42.3% reported that a patient they have prescribed opioids for developed an opioid dependency, whereas 35.3% do not believe that opioid use is a problem in their practice. Of note, 30.3% reported prescribing refills, and factors significantly associated with increased prescribing of refills included a greater number of years in practice (P < 0.001) and practicing in a suburban rather than an urban or rural environment (P = 0.03)., Conclusion: Orthopaedic surgeons rarely prescribe any refills, tend to prescribe less opioids to teenagers than adults, and prescribe fairly uniformly for patients who are treated nonsurgically or undergo minor or arthroscopic surgery. They exhibit considerable variation in prescribing for fractures and major procedures.

Background: Alternative dispute resolution (ADR) refers to techniques used to resolve conflicts without going to the courtroom. As healthcare and malpractice costs continue to rise, there is growing interest in tactics such as early apology, mediation, and arbitration in the medical arena., Questions/purposes: (1) Why is ADR needed? (2) Is ADR useful in health care? (3) What are the current legal and political developments favoring ADR? (4) What obstacles remain?, Methods: We performed MEDLINE, PubMed, and Google Scholar searches with key words "medical malpractice", "ADR", and "alternative dispute resolution" to obtain public policy studies, law review articles, case analyses, ADR surveys, and healthcare review articles., Results: Early apology and disclosure programs report 50% to 67% success in avoiding litigation as well as substantial reductions in the amount paid per claim. Mediation boasts 75% to 90% success in avoiding litigation, cost savings of $50,000 per claim, and 90% satisfaction rates among both plaintiffs and defendants. Arbitration is viewed as less satisfying and less efficient than mediation but still more time- and cost-effective than litigation. The current legal environment is favorable to ADR with recent court decisions upholding pretreatment arbitration clauses. The main obstacle to ADR is the mandatory reporting requirement of the National Practitioner Data Bank (NPDB)., Conclusions: ADR has the potential to help reform the current tort system, reducing cost and increasing both parties' satisfaction. Easing the reporting requirements for the NPDB would lead to more widespread acceptance of ADR among physicians.

Suture anchor fixation failure can occur if the anchor pulls out of bone. We hypothesized that suture anchor fixation can be augmented with polymethylmethacrylate cement, and that polymethylmethacrylate can be used to improve fixation in a stripped anchor hole. Six matched cadaveric proximal humeri were used. On one side, suture anchors were placed and loaded to failure using a ramped cyclic loading protocol. The stripped anchor holes then were injected with approximately 1 cc polymethylmethacrylate, and anchors were replaced and tested again. In the contralateral humerus, polymethylmethacrylate was injected into anchor holes before anchor placement and testing. In unstripped anchors, polymethylmethacrylate increased the number of cycles to failure by 34% and failure load by 71% compared with anchors not augmented with polymethylmethacrylate. Polymethylmethacrylate haugmentation of stripped anchors increased the cycles to failure by 31% and failure load by 111% compared with unstripped uncemented anchors. No difference was found in cycles to failure or failure load between cemented stripped anchors and cemented unstripped anchors. Polymethylmethacrylate can be used to augment fixation, reducing the risk of anchor pull-out failure, regardless whether the suture anchor hole is stripped or unstripped.

The transplantation of autologous chondrocytes under a periosteal flap has been used to treat focal cartilage defects. Results have been promising but occasionally involve complications ranging from graft hypertrophy to detachment. The objective of this study was to determine if gravitational forces affect the uniformity of cell distribution within the defect. Using an ex vivo bovine model, the orientation relative to gravity of a repaired full-thickness articular cartilage defect was found to affect the initial distribution of transplanted chondrocytes, prelabeled with 3H-thymidine. After 4 hours, the injected cells (3H-radioactivity) were primarily at the base of the defect (79%) in samples oriented in the up position, primarily at the dependent semicylindrical half of the defect (83%) in samples oriented to the side, and primarily at the periosteal top of the defect (78%) in samples oriented upside-down. Subsequently, the cell distribution remained unchanged after reorientation into other positions. These results indicate that injected chondrocytes localize under the influence of gravity within the initial few hours after injection. Therefore, the defect orientation during this time can be an important factor in the uniformity of cell distribution in the autologous chondrocyte implantation procedure and may be an important determinant of the ultimate clinical outcome.
