Distal Femoral Tracker Pin Placement Prevents Delayed Pin Tract-Induced Fracture in Robotic-Assisted Total Knee Arthroplasty: Results of Minimum 1-Year Follow-Up
J Knee Surg DOI: 10.1055/s-0042-1749605The purpose of this study was to determine the outcomes of the placement of a pin tracker in the distal femur in robotic-assisted total knee arthroplasty (TKA) over a minimum follow-up period of 1 year. A consecutive series of 81 TKAs were performed in 59 patients using a robotic-assisted system (Mako) at our hospital. The mean follow-up period was 1.1 years (range, 1–1.2 years). No periprosthetic fracture at a pin tracker site was reported at a minimum of 1 year of follow-up. No patients reported minor or major complications associated with the distal femoral pins. In addition, uni...

Preoperative Activity Level an Indicator of Postoperative Functional Outcomes with a Contemporary Revision Total Knee System
J Knee Surg DOI: 10.1055/s-0042-1749606As the population requiring revision total knee arthroplasty (rTKA) grows, varying preoperative conditions may need to be considered when attempting to predict postoperative outcomes. Considering preoperative activity levels may help manage the expectations of patients. The purpose of this study was to analyze the outcomes of low- and high-activity subgroups of patients receiving a contemporary rTKA. One hundred and eighty-one rTKA patients enrolled in a prospective multicenter study were evaluated over a minimum follow-up of 2 years postoperatively. Patients were divided into two gro...

Outcomes of Displaced Tibial Tubercle Fractures in Adolescents
This study was approved by the College of Medicine Institutional Review Board. A retrospective review was performed at our institution for patients who underwent surgical treatment of tibial tubercle fractures. Patient demographics, injury characteristics, and outcomes were recorded. A p-value of <0.05 was considered statistically significant. Nineteen male patients were identified. The average age was 14.6 years, and the average body mass index was 25.8. Basketball (63%) was the most common mechanism of injury. No patient was treated with bicortical screws. Two patients had preoperative computed tomography. One patient...

Do Patellar Tendon Repairs Have Better Outcomes than Quadriceps Tendon Repairs? A Prospective Cohort Analysis
J Knee Surg DOI: 10.1055/s-0042-1750060Patellar tendon (PT) and quadriceps tendon (QT) ruptures represent significant injuries and warrant surgical intervention in most patients. Outcome data are predominantly retrospective analyses with low sample sizes. There are also minimal data comparing QT and PT repairs and the variables impacting patient outcomes. The level of evidence of the study is level II (prognosis). From the prospective OME cohort, 189 PT or QT repairs were performed between February 2015 and October 2019. Of these, 178 were successfully enrolled (94.2%) with 1-year follow-up on 141 (79.2%). Baseline demogra...

Trends in the Prevalence and Postoperative Surgical Complications for Smokers Who Underwent a Total Knee Arthroplasty from 2011 to 2019: An Analysis of 406,553 Patients
This study aims to investigate (1) the incidence of 30-day complications following TKA in smokers and (2) trends in preoperative smoking status among TKA patients. In this study, patients undergoing primary elective TKA in the United States from 2011 to 2019 were identified in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database. Our cohort included 406,553 cases, 8.13% of which had smoked cigarettes within 1 year of undergoing TKA. Smokers were propensity score-matched to a group of nonsmokers, with each n = 32,533. The incidences of 30-day complications, readmission, an...

What Are the Drivers of Readmission for Serious Venous Thromboembolic Events after Primary Total Knee Arthroplasty? An Analysis of 862,915 Patients
This study examines the patient and hospital characteristics associated with readmission for serious VTE after TKA. The National Readmission Database (NRD) from the Agency of Healthcare Research and Quality (AHRQ) was queried for patients who underwent primary TKA from January 2016-December 2018. The study population consisted of patients who were readmitted within 90 days following primary TKA with a primary diagnosis of VTE. Multivariable regression models were constructed to evaluate patient characteristics (age, sex, insurance, elective nature of procedure, hospital characteristics, discharge status, income, and comorb...

Arthroscopic Meniscal Healing following Medial Meniscus Posterior Root Repair: A Comparison between Two Suture Materials
This study aimed to evaluate the clinical outcomes after performing MMPRT pullout repair using different suture materials. We hypothesized that better clinical outcomes would be achieved using ultra-high molecular weight polyethylene (UHMWPE) tape compared with a normal polyester suture. Thirty-seven patients who underwent MM posterior root repair between November 2019 and May 2020 were retrospectively investigated. Pullout repair was performed using a hollow no. 0 polyester suture (n = 14) and UHMWPE tape (n = 23). Clinical outcomes were assessed preoperatively and at 1 year postoperatively, using the Lysholm knee...

Comparison of Arthroscopic versus Open Placement of the Fibular Tunnel in Posterolateral Corner Reconstruction
Conclusions Reliable soft-tissue and bony landmarks of the fibular head allow arthroscopic anatomic fibular tunnel placement in PLC surgery, which shows a lower risk of tunnel malposition compared with open surgical techniques. Future studies will have to show whether clinical results of arthroscopic PLC reconstruction are in line with this study's technical results.

Is Conversion Total Knee Arthroplasty a Distinct Surgical Procedure? A Comparison to Primary and Revision Total Knee Arthroplasty
J Knee Surg DOI: 10.1055/s-0042-1750059Conversion total knee arthroplasty (TKA) is suggested to incur similar complication rates to revision arthroplasties. However, current billing codes do not allow for the differentiation between this operation and primary TKAs. Therefore, the purpose of this study was to compare outcomes of these two surgeries, as well as revision TKAs. Specifically, we analyzed (1) medical complications, (2) surgical complications, and (3) revision rates at 90 days and 1 year. We queried a national, all-payer database to identify patients who underwent TKA without prior implants (n = 1,358,767), r...

HTX-011 in Combination with Multimodal Analgesic Regimen Minimized Severe Pain and Opioid Use after Total Knee Arthroplasty in an Open-Label Study
J Knee Surg DOI: 10.1055/s-0042-1747945Total knee arthroplasty (TKA) can be associated with significant postoperative pain despite multimodal analgesic (MMA) protocols, and most patients require the use of opioids postoperatively. HTX-011 is a dual-acting local anesthetic containing bupivacaine and low-dose meloxicam in an extended-release polymer. In a prior randomized controlled trial (RCT), HTX-011 reduced pain and opioid use through 72 hours after TKA compared with bupivacaine hydrochloride. This open-label study (NCT03974932) evaluated the efficacy and safety of HTX-011 combined with an MMA regimen in patients under...

Remnant-Preserved Single-Bundle Anterior Cruciate Ligament Augmentation in Multi-ligamentous Knee Reconstruction
This study was conducted to present remnant-preserving anterior cruciate ligament (ACL) augmentation as a useful option for partial ACL injury in multiligament knee injury (MLKI) cases, which may also contribute to conserving graft resources. The present study involved patients diagnosed with MLKI at our institute from Spring 2006 to February 2021. A total of 71 MLKI cases were provided surgery due to knee instability and disability. For every patient, an arthroscopic diagnostic was performed to ensure that ACL tear and a remnant were present. When the ACL remnant was classified into group 2, 3, or 4 of Nakamae's classific...
