Prevalence of Knee Chondrocalcinosis in Hospital and Clinic Patients Aged 50 or Older*

Abstract

The prevalence of chondrocalcinosis was studied in 574 hospital and clinic patients aged 50 or older who had undergone x-ray examination of the knee. Chondrocalcinosis was found in 9.6 percent of all these patients, in 5 percent of the 50-64 age group, and in 14.6 percent of the 65-94 age group. The prevalence of knee chondrocalcinosis increased in stepwise fashion between the ages of 65 and 80. A review of the literature and of the data on our few patients over the age of 80 suggests the existence of an even higher prevalence among persons of this advanced age group.

Local Deposition of Calcium Pyrophosphate Crystals in Evolution of Knee Osteoarthritis

“…The high frequency of patients with unilateral knee involvement in the OA + CPPD group of our study seems also to corroborate the predisposing role of OA in local CPPD deposition. The high frequency (25%) of CPPD crystal deposition in our series of patients with knee OA supports the idea that there is some causal relationship between both conditions; indeed, the prevalence of CPPD crystal deposition of the knee in the general population of the same age without OA is much lower (10%-15%) [1,6,7,22,23]. The question whether obesity could play a role in CPPD crystal deposition was addressed.…”

CPPD crystal deposition disease of the cervical spine: A common cause of acute neck pain encountered in the neurology department

“…Pseudogout is one of the most common forms of crystal-associated arthritis associated with CPPD deposition in the joints and periarticular tissues (1)(2)(3). The prevalence of CPPD deposition is extremely high and it is reported that knee chondrocalcinosis, which is assumed to be due to CPPD deposition, is found in 9.6% of individuals older than 50 years old, and this incidence increases with age (4,5). Attacks of pseudogout can be either monoarticular or oligoarticular, and the most commonly affected joints are the knees, followed by the shoulders, wrists, and ankles (2).…”

Enfermedad por depósito de cristales de pirofosfato cálcico en la articulación temporomandibular con extensión intracraneal: A propósito de un caso

“…Además de la rodilla, otras articulaciones que pueden resultar afectas son las caderas, los hombros, los codos y los tobillos. Algunos estudios 4 han mostrado un incremento en la prevalencia de esta enfermedad con la edad. Cuando la enfermedad se manifiesta en la ATM, el dolor y la disfunción articular pueden conducir a un diagnóstico más precoz que en otras articulaciones, aunque en la práctica clínica esta sintomatología puede enmascarar realmente la patología subyacente.…”
