What is the Accuracy of Nuclear Imaging in the Assessment of Periprosthetic Knee Infection? A Meta-analysis

Steven J. Verberne MD, Remko J. A. Sonnega MD, Olivier P. P. Temmerman MD, PhD, Pieter G. Raijmakers MD, PhD

In the assessment of possible periprosthetic knee infection, various imaging modalities are used without consensus regarding the most accurate technique.

No Clinically Important Difference in Knee Scores or Instability Between Transtibial and Inlay Techniques for PCL Reconstruction: A Systematic Review

Young-Soo Shin MD, Hyun-Jung Kim MPH, PhD, Dae-Hee Lee MD, PhD

It is unclear whether the biomechanical superiority of the inlay technique over the transtibial technique, arising from avoidance of the killer turn at the graft-tunnel margin of the proximal tibia during posterior cruciate ligament (PCL) reconstruction, leads to better knee scores or greater knee stability.

Lateral-compartment Osteophytes are not Associated With Lateral-compartment Cartilage Degeneration in Arthritic Varus Knees

Wenzel Waldstein MD, Maximilian F. Kasparek MD, Martin Faschingbauer MD, Reinhard Windhager MD, PhD, Friedrich Boettner MD

Progression of arthritis in the lateral compartment is one of the main failure modes of unicompartmental knee arthroplasty (UKA). The decision regarding whether to perform a medial UKA sometimes is made based on whether lateral-compartment osteophytes are visible on plain radiographs obtained before surgery, but it is not clear whether the presence of lateral-compartment osteophytes signifies that the cartilage in the lateral compartment is arthritic.

No Decrease in Knee Survivorship or Outcomes Scores for Patients With HIV Infection Who Undergo TKA

Kimona Issa MD, Todd P. Pierce MD, Steven F. Harwin MD, Anthony J. Scillia MD, Anthony Festa MD, Michael A. Mont MD

HIV is prevalent worldwide and numerous patients with this diagnosis ultimately may become candidates for TKA. Although some studies have suggested that complications are more common in patients with HIV who undergo TKA, these studies largely were done before the contemporary era of HIV management; moreover, it is unclear whether patients with HIV achieve lower patient-reported outcome scores or inferior implant survivorship.

What Differences in Morphologic Features of the Knee Exist Among Patients of Various Races? A Systematic Review

T. K. Kim MD, PhD, Mark Phillips BSc, Mohit Bhandari MD, PhD, John Watson, Rajesh Malhotra MS, FRCS

Most TKA prostheses are designed based on the anatomy of white patients. Individual studies have identified key anthropometric differences between the knees of the white population and other major ethnic groups, yet there is limited understanding of what these findings may indicate if analyzed collectively.

Does the Utilization of Allograft Tissue in Medial Patellofemoral Ligament Reconstruction in Pediatric and Adolescent Patients Restore Patellar Stability?

Eric Hohn MD, Nirav K. Pandya MD

Medial patellofemoral ligament (MPFL) reconstruction is one of several surgical procedures used to treat patellofemoral instability. Use of allograft tissue can preserve autogenous tissue and may be preferable in patients with connective tissue disorders or ligamentous laxity. Although there are successful reports in adults, it is unclear if the use of allograft tissue in MPFL reconstruction can restore patellofemoral stability in children and adolescents.

Osteochondritis Dissecans Lesions in Family Members: Does a Positive Family History Impact Phenotypic Potency?

Alex L. Gornitzky MD, R. Justin Mistovich MD, Brittany Atuahuene BA, Eileen P. Storey BA, Theodore J. Ganley MD

Although repetitive microtrauma and athletic overuse patterns are most commonly associated with osteochondritis dissecans (OCD), recent studies have identified a potential genetic predisposition for OCD. Several case series have documented family pedigrees that support autosomal-dominant inheritance, but the families in these studies were all selected as a result of unique histories that may not accurately represent OCD inheritance patterns at large. Because there has been little investigation beyond these case reports, we aimed to describe a broader, more representative pattern of OCD inheritance applicable to all affected patients.

Novel Augmentation Technique for Patellar Tendon Repair Improves Strength and Decreases Gap Formation: A Cadaveric Study

James C. Black MD, William M. Ricci MD, Michael J. Gardner MD, Christopher M. McAndrew MD, MSc, Avinesh Agarwalla BS, Robert D. Wojahn MD, Orchid Abar, Simon Y. Tang PhD

Patellar tendon ruptures commonly are repaired using transosseous patellar drill tunnels with modified-Krackow sutures in the patellar tendon. This simple suture technique has been associated with failure rates and poor clinical outcomes in a modest proportion of patients. Failure of this repair technique can result from gap formation during loading or a single catastrophic event. Several augmentation techniques have been described to improve the integrity of the repair, but standardized biomechanical evaluation of repair strength among different techniques is lacking.

No Difference in Early Analgesia Between Liposomal Bupivacaine Injection and Intrathecal Morphine After TKA

John W. Barrington MD, Roger H. Emerson MD, Scott T. Lovald PhD, Adolph V. Lombardi MD, Keith R. Berend MD

Opioid analgesics have been a standard modality for postoperative pain management after total knee arthroplasty (TKA) but are also associated with increased risk of nausea, pruritus, vomiting, respiratory depression, prolonged ileus, and cognitive dysfunction. There is still a need for a method of anesthesia that can deliver effective long-term postoperative pain relief without incurring the high cost and health burden of opioids and nerve blocks.

Disparities in TKA Outcomes: Census Tract Data Show Interactions Between Race and Poverty

Susan M. Goodman MD, Lisa A. Mandl MD, MPH, Michael L. Parks MD, Meng Zhang PhD, Kelly R. McHugh MA, Yuo-Yu Lee MS, Joseph T. Nguyen MPH, Linda A. Russell MD, Margaret H. Bogardus BA, Mark P. Figgie MD, Anne R. Bass MD

Race is an important predictor of TKA outcomes in the United States; however, analyses of race can be confounded by socioeconomic factors, which can result in difficulty determining the root cause of disparate outcomes after TKA.
