All-polyethylene Tibial Components are Equal to Metal-backed Components: Systematic Review and Meta-regression

Klaas Auke Nouta MD, Wiebe C. Verra MD, Bart G. Pijls MD, Jan W. Schoones MA, Rob G. H. H. Nelissen MD, PhD

Less than 1% of all primary TKAs are performed with an all-polyethylene tibial component, although recent studies indicate all-polyethylene tibial components are equal to or better than metal-backed ones.

Patient-specific Total Knee Arthroplasty Required Frequent Surgeon-directed Changes

Benjamin M. Stronach MD, Christopher E. Pelt MD, Jill Erickson PA, Christopher L. Peters MD

Patient-specific instrumentation potentially improves surgical precision and decreases operative time in total knee arthroplasty (TKA) but there is little supporting data to confirm this presumption.

Validation of the Korean Version of the Oxford Knee Score in Patients Undergoing Total Knee Arthroplasty

Il Soo Eun MD, Ok Gul Kim MD, Chang Kyu Kim MD, Hong Seok Lee MD, Jung Sub Lee MD, PhD

Although translated versions of the Oxford Knee Score (OKS) in several languages are available, the absence of a Korean version precludes comparing data from Korea with that from other countries using the OKS.

Do Fresh Osteochondral Allografts Successfully Treat Femoral Condyle Lesions?

Yadin D. Levy MD, Simon Görtz MD, Pamela A. Pulido BSN, Julie C. McCauley MPHc, William D. Bugbee MD

Fresh osteochondral allograft transplantation is an increasingly common treatment option for chondral and osteochondral lesions in the knee, but the long-term outcome is unknown.

Does Minimally Invasive Total Knee Arthroplasty Improve Isokinetic Torque?

Michael C. Liebensteiner MD, PhD, Martin Krismer MD, Arnold Koller PhD, Barbara Semenitz MD, Eckart Mayr MD

Less invasive dissection of the extensor apparatus, one of the aspects of minimally invasive surgical (MIS) TKA, might result in less reduction of postoperative quadriceps strength. However, it is unclear whether MIS is associated with less strength reduction.

Postoperative Alignment and ROM Affect Patient Satisfaction After TKA

Shuichi Matsuda MD, Shinya Kawahara MD, Ken Okazaki MD, Yasutaka Tashiro MD, Yukihide Iwamoto MD

Patient satisfaction has increasingly been recognized as an important measure after total knee arthroplasty (TKA). However, we do not know yet how and why the patients are satisfied or dissatisfied with TKA.

Surgical Technique: Vastus Medialis and Vastus Lateralis as Flap Transfer for Knee Extensor Mechanism Deficiency

Leo A. Whiteside MD

Loss of the quadriceps tendon, patella, and patellar tendon leaves a major anterior defect that is difficult to close and compromises knee extension strength. Gastrocnemius muscle transfer does not sufficiently cover such major defects. This paper describes a new surgical technique that addresses these defects and the results of eight cases of revision TKA managed with this new technique.

Rotating-platform Has No Surface Damage Advantage Over Fixed-bearing TKA

Kirsten Stoner MEng, Seth A. Jerabek MD, Stephanie Tow BA, Timothy M. Wright PhD, Douglas E. Padgett MD

Rotating-platform TKA, although purported to have superior kinematics, has shown no clinical advantages over those of fixed-bearing TKA. Our design-matched retrieval study aimed to investigate if differences in bearing wear damage exist between fixed- and mobile-bearing TKAs with similar condylar geometry.

Computer-assisted Total Knee Arthroplasty Is Currently of No Proven Clinical Benefit: A Systematic Review

R. Stephen J. Burnett MD, FRCSCC, Robert L. Barrack MD

Navigated total knee arthroplasty (TKA) may improve coronal alignment outliers; however, it is unclear whether navigated TKA improves the long-term clinical results of TKA.

Can Fresh Osteochondral Allografts Restore Function in Juveniles With Osteochondritis Dissecans of the Knee?

Roger Lyon MD, Carl Nissen MD, Xue Cheng Liu MD, PhD, Brian Curtin MD

Failure of initial treatment for juvenile osteochondritis dissecans (OCD) may require further surgical intervention, including microfracture, autograft chondrocyte implantation, osteochondral autografting, and fresh osteochondral allografting. Although allografts and autografts will restore function in most adults, it is unclear whether fresh osteochondral allograft transplantations similarly restore function in skeletally immature patients who failed conventional treatment.
