Osteolysis in Well-functioning Fixed- and Mobile-bearing TKAs in Younger Patients

Young-Hoo Kim MD, Yoowang Choi MD, Jun-Shik Kim MD

Periprosthetic osteolysis is an increasingly prevalent complication of TKA. To reduce the polyethylene wear and periprosthetic osteolysis, particularly in young patients, the design of the contemporary fixed-bearing TKAs has been modified and mobile-bearing TKAs have been introduced.

Rotational References for Total Knee Arthroplasty Tibial Components Change with Level of Resection

Bradley P. Graw MD, Alexander H. Harris PhD, Krishna R. Tripuraneni MD, Nicholas J. Giori MD, PhD

Various landmarks can guide tibial component rotational alignment in routine TKA, but with the deeper tibial resection levels common in complex primary and revision TKAs, it is unknown whether these landmarks remain reliable.

Routine Surveillance of Modular PFC TKA Shows Increasing Failures after 10 Years

Andrew S. Malin MD, John J. Callaghan MD, Kevin J. Bozic MD, MBA, Steve S. Liu MD, Devon D. Goetz MD, Nicholas Sullivan BS, Scott S. Kelley MD

A 10-year survivorship of 100% was reported for patients with PFC cruciate-retaining prostheses. Beyond 10 years, we observed additional polyethylene wear likely related to thin liners gamma-irradiated in air and were concerned this wear might predispose to implant construct failure.

Knee Pain in a 17-year-old Girl

Medial Knee Osteoarthritis Treated by Insoles or Braces: A Randomized Trial

Tom M. Raaij MD, PhD, Max Reijman PhD, Reinoud W. Brouwer MD, PhD, Sita M. A. Bierma-Zeinstra PhD, Jan A. N. Verhaar MD, PhD

There is controversial evidence regarding whether foot orthoses or knee braces improve pain and function or correct malalignment in selected patients with osteoarthritis (OA) of the medial knee compartment. However, insoles are safe and less costly than knee bracing if they relieve pain or improve function.

All-epiphyseal Anterior Cruciate Ligament Reconstruction in Skeletally Immature Patients

J. Todd R. Lawrence MD, PhD, Andrea L. Bowers MD, Jonathan Belding MD, Stephanie R. Cody BS, Theodore J. Ganley MD

Treating ACL injuries in prepubescent patients requires balancing the risk of chondral and meniscal injuries associated with delaying treatment against the risk of growth disturbance from early surgical reconstruction. Multiple physeal respecting techniques have been described to address this vulnerable population; however, none restore the native ACL attachments while keeping the graft and fixation entirely in the epiphysis.

Fresh Osteochondral Allografting for Steroid-associated Osteonecrosis of the Femoral Condyles

Simon Görtz MD, Allison J. Young BS, William D. Bugbee MD

Osteonecrosis is a complication of corticosteroid therapy with limited treatment options in young, active patients. These options include debridement, core decompression, osteotomy, allografting, and partial or total knee replacement. Few studies exist regarding the use of osteochondral allografts for treatment of steroid-associated osteonecrosis.

Subcutaneous versus Intraarticular Indwelling Closed Suction Drainage after TKA: A Randomized Controlled Trial

Eun Seok Seo MD, Su Won Yoon RN, In Jun Koh MD, Chong Bum Chang MD, PhD, Tae Kyun Kim MD, PhD

TKA can involve substantial bleeding, and the issue regarding whether vacuum drainage should be used during TKA continues to be debated as both methods have disadvantages.

Radiographic Prevalence of Femoroacetabular Impingement in a Young Population with Hip Complaints Is High

Leah M. Ochoa MD, Laura Dawson DO, Jeanne C. Patzkowski MD, Joseph R. Hsu MD

Femoroacetabular impingement (FAI) is reportedly a prearthritic condition in young adults that can progress to osteoarthritis. However, the prevalence of FAI is unknown in the young, active population presenting with hip complaints.

Do Porous Tantalum Implants Help Preserve Bone?: Evaluation of Tibial Bone Density Surrounding Tantalum Tibial Implants in TKA

Alicia K. Harrison MD, Terence J. Gioe MD, Christine Simonelli MD, Penny J. Tatman MPH, Mary C. Schoeller RT(R), CDT

TKA with conventional metal-backed tibial implants subjects the tibial metaphysis to stress shielding, with resultant loss of bone density.
