Simultaneous Total Knee Arthroplasty and Proximal Tibiofibular Joint Arthrodesis: A Case Report.

Case: A 57-year-old man presented with tricompartmental left knee osteoarthritis, as well as proximal tibiofibular joint arthritis and a ganglion cyst. He underwent simultaneous total knee arthroplasty and proximal tibiofibular joint arthrodesis, with an excellent outcome.

Conclusion: Proximal tibiofibular joint arthritis is uncommon and may be associated with tibiofemoral arthritis, proximal tibiofibular joint instability, and ankylosing spondylitis.

Reliability of three radiographic classification systems for knee osteoarthritis among observers of different experience levels.

Objective: To assess the intra- and inter-observer reliability of three commonly referenced radiographic classification systems for knee osteoarthritis in a cohort of arthroplasty candidates.

Materials And Methods: Pre-operative radiographs of 112 patients who subsequently underwent primary total knee arthroplasty were evaluated by four independent observers of varying experience. Each x-ray was de-identified, randomised, and classified according to the International Knee Documentation Committee, Kellgren-Lawrence, and Ahlbäck classifications.
