Medial unicompartmental knee arthroplasty: increasingly uniform patient demographics despite differences in surgical volume and usage-a descriptive study of 8,501 cases from the Danish Knee Arthroplasty Registry.

Acta Orthop 2019 Apr 11:1-10. Epub 2019 Apr 11.

a Department of Orthopaedic Surgery, Clinical Orthopaedic Research Hvidovre (CORH) , Copenhagen University Hospital Hvidovre , Denmark ;

Background and purpose - Using contemporary indications, up to 50% of patients undergoing knee arthroplasty are eligible for unicompartmental knee arthroplasty (UKA), and lower UKA use likely reflects a restrictive approach to patient selection. Since broader indications have been successfully introduced, and low surgical volume and UKA percentage (usage) are associated with higher revision rates, it is of interest whether the actual use of UKA has changed accordingly. We explored this by assessing time trends in patient demographics and whether these are associated with center UKA volume and usage. Read More

Superior fixation and less periprosthetic stress-shielding of tibial components with a finned stem versus an I-beam block stem: a randomized RSA and DXA study with minimum 5 years' follow-up.

Acta Orthop 2019 Apr 23;90(2):165-171. Epub 2019 Jan 23.

c Department of Orthopaedic Surgery , Aarhus University Hospital.

Background and purpose - The stem on the tibial component of total knee arthroplasty provides mechanical resistance to lift-off, shear forces, and torque. We compared tibial components with finned stems (FS) and I-beam block stems (IS) to assess differences in implant migration. Patients and methods - In a patient-blinded RCT, 54 patients/knees (15 men) with knee osteoarthritis at a mean age of 77 years (70-90) were randomly allocated to receive tibial components with either a FS (n = 27) or an IS (n = 27).

Relationship between outcome scores and knee laxity following total knee arthroplasty: a systematic review.

Acta Orthop 2019 Feb 20;90(1):46-52. Epub 2018 Dec 20.

b Department of Orthopedic Surgery , Copenhagen University Hospital Herlev-Gentofte , Hellerup , Denmark.

Background and purpose - Instability following primary total knee arthroplasty (TKA) is, according to all national registries, one of the major failure mechanisms leading to revision surgery. However, the range of soft-tissue laxity that favors both pain relief and optimal knee function following TKA remains unclear. We reviewed current evidence on the relationship between instrumented knee laxity measured postoperatively and outcome scores following primary TKA. Read More
