Prevalence of Radiographic Knee and Wrist Chondrocalcinosis in Adana Province, Türkiye: A Hospital-Based Retrospective Study

Background/Aims: Multiple epidemiological studies in different ethnic groups demonstrate diverse results about the prevalence of chondrocalcinosis (CC), yet no definitive data are available concerning its frequency in most countries. Furthermore, the prevalence of CC in the Turkish population is not known to date. The aim of this study was to investigate the frequency of radiographic CC in the knee, wrist, or both joints in individuals aged ≥50 years from the hospital records of the last 5 years. Materials and Methods: In this retrospective study, radiographs of the knee and/or wrist taken at Çukurova University Faculty of Medicine Balcalı Hospital were reviewed by an experienced physiatrist, rheumatologist, and radiologist.

Results: A total of 1818 radiographs from 772 individuals were included in the study. A total of 32 individuals exhibited calcification in at least 1 knee or wrist in total. Of these, 9.3% were male and 90.6% were female, with an overall radiographic prevalence of 4.1%. The prevalence of radiographic knee CC was found to be 4.1%, while that of wrist CC was 3.2%. Only 2 female patients exhibited CC in both the knee and wrist joints simultaneously. The frequency of CC in bilateral knee joints have been increased with age and no significant association was found regarding CC coexisting with other comorbidities except hyperparathyroidism.

Conclusion: The prevalence of radiographically detected knee and wrist CC in the Turkish population has not yet been reported. These findings emphasize the need for clinical research that could increase awareness and advance knowledge of the relationship between CC and possible risk factors in Türkiye.
