Stress Radiography for the Diagnosis of Knee Ligament Injuries: A Systematic Review

Evan W. James BS, Brady T. Williams BS, Robert F. LaPrade MD, PhD

Stress radiography is a widely used diagnostic tool to assess injury to the anterior and posterior cruciate ligaments and the medial and lateral structures of the knee. However, to date, numerous techniques have been reported in the literature with no clear consensus as to which methodology is best for assessing ligament stability.

Does Chondrocalcinosis Affect Knee Society Scores and Range of Motion After TKA?

Gwo-Chin Lee MD, Paul A. Lotke MD

Chondrocalcinosis is manifested by crystalline deposits of calcium commonly found during primary TKA for osteoarthritis. Its frequency among patients undergoing TKA is poorly defined, as is its influence on pain or function after TKA.

Risk Factors for Revision Within 10 Years of Total Knee Arthroplasty

Christopher J. Dy MD, MSPH, Robert G. Marx MD, MSc, Kevin J. Bozic MD, MBA, Ting Jung Pan MPH, Douglas E. Padgett MD, Stephen Lyman PhD

An in-depth understanding of risk factors for revision TKA is needed to minimize the burden of revision surgery. Previous studies indicate that hospital and community characteristics may influence outcomes after TKA, but a detailed investigation in a diverse population is warranted to identify opportunities for quality improvement.

Pain Trajectories Identify Patients at Risk of Persistent Pain After Knee Arthroplasty: An Observational Study

Patricia M. Lavand’homme MD, PhD, Irina Grosu MD, Marie-Noëlle France RN, Emmanuel Thienpont MD, MBA

Persistent postsurgical pain is a major source of dissatisfaction after knee arthroplasty. Postoperative pain trajectories allow a dynamic view of pain resolution after surgery and might help to identify patients at risk for persistent pain.

Medial Open Wedge High Tibial Osteotomy: Can Delayed or Nonunion Be Predicted?

Albert H. Houten MD, Petra J. C. Heesterbeek PhD, Ronald J. Heerwaarden MD, PhD, Tony G. Tienen MD, PhD, Ate B. Wymenga MD, PhD

The opening wedge approach to high tibial osteotomy (HTO) is perceived to have some advantages relative to the closing wedge approach but it may be associated with delayed and nonunions. Because nonunions evolve over months, it would be advantageous to be able to identify risk factors for and early predictors of nonunion after medial opening wedge HTO.

Are Younger Patients Undergoing TKAs Appropriately Characterized As Active?

James A. Keeney MD, Ryan M. Nunley MD, Rick W. Wright MD, Robert L. Barrack MD, John C. Clohisy MD

The use of TKAs in young patients is increasing. Demographic characteristics and activity levels among this patient group may affect implant selection, performance, and survivorship. Patient age (≤ 55 years) and preoperative diagnosis have been used to define this patient group, with the presumption that these patients are more active than older patients with similar indications for TKA.

The Changing Demographics of Knee Dislocation: A Retrospective Database Review

Gabriel A. Arom BS, Michael G. Yeranosian MD, Frank A. Petrigliano MD, Rodney D. Terrell MD, David R. McAllister MD

Knee dislocations are uncommon but devastating orthopaedic injuries. Little is known about their frequency and the types of patients who are affected.

Meniscal Injury After Adolescent Anterior Cruciate Ligament Injury: How Long Are Patients at Risk?

Zachary D. Guenther MD, Vimarsha Swami BSc, Sukhvinder S. Dhillon MB, ChB, MRCP, FRCR, Jacob L. Jaremko MD, PhD, FRCPC

Delay of as much as 5 months between ACL injury and surgery is known to be associated with increased risk of a medial meniscal tear, but the risk of additional meniscal tear progression with a longer delay to surgery is unclear.

Intraarticular Analgesia Versus Epidural Plus Femoral Nerve Block After TKA: A Randomized, Double-blind Trial

Keith R. Reinhardt MD, Shivi Duggal BS, MBA, Ben-Paul Umunna BA, Gregory A. Reinhardt MSPT, Denis Nam MD, Michael Alexiades MD, Charles N. Cornell MD

Pain management after TKA remains challenging and the efficacy of continuously infused intraarticular anesthetics remains a controversial topic.

Unicompartmental Knee Arthroplasty Survivorship is Lower Than TKA Survivorship: A 27-year Finnish Registry Study

Tuukka Niinimäki MD, Antti Eskelinen MD, PhD, Keijo Mäkelä MD, PhD, Pasi Ohtonen MSc, Ari-Pekka Puhto MD, Ville Remes MD, PhD

Balancing the relative advantages and disadvantages of unicompartmental knee arthroplasties (UKAs) against those for TKAs can be challenging. Survivorship is one important end point; arthroplasty registers repeatedly report inferior midterm survival rates, but longer-term data are sparse. Comparing survival directly by using arthroplasty register survival reports also may be inadequate because of differences in indications, implant designs, and patient demographics in patients having UKAs and TKAs.
