Summary: Consolidating work previously presented at this forum we present results of multivariable regression analysis correlating anatomical distribution of radiological degeneration in the knee and the Oxford Knee Score in a cohort of 599 knees in 455 patients with end-stage osteoarthritis.

Background

Patient dissatisfaction with the results of up to 20 % after TKA has driven exploration and innovation to address potential causes for this. Examples include investment in research into alignment philosophy, improved prosthetic survival with vitamin enriched highly crossed linked PE and increasing use of computer assistance in the planning and execution of TKA. To our knowledge, no research has addressed the impact of the anatomical distribution of OA on patient satisfaction following TKA.

Methods

Cohort study of 496 knees. Exposure categories of isolated medial (264 (53%)), lateral (104 (21%)), patellofemoral (66 (13%)) and preserved joint space as baseline. Prospectively collected data on pre-operative and 12 month post-operative Oxford Knee Score, age, sex and BMI.

Results

There was a statistically significant variation in adjusted Oxford Knee Score dependent upon compartment involvement. Participants with lateral compartment OA demonstrated the greatest clinical improvement, followed by those with medial OA. Participants with isolated PFJOA did not improve beyond the baseline category.

Conclusion

the anatomical distribution of radiographic OA change is a factor that contributes to postoperative patient satisfaction with TKA.
