EpistemisPathological joint crepitation
Specialty: Musculoskeletal.
Why it occurs
- Severe wear of the articular cartilage with bone-on-bone friction (advanced osteoarthritis)
- Rupture of fibrocartilaginous structures (menisci, labrum, tendons)
- Presence of gas bubbles in the synovial fluid (physiological cavitation phenomenon; benign if there is no pain)
- Stenosing tenosynovitis or tendon friction on bone reliefs
- Severe patellar chondropathy (patellofemoral friction)
- Monosodium urate microcrystal deposits in cartilage (gout)
Initial workup
Simple weight-bearing x-ray of the affected joint | Dynamic musculoskeletal ultrasound to assess tendon-bone or bursa interaction during movement | Joint magnetic resonance imaging to evaluate articular cartilage in a three-dimensional manner.
red flags
Joint cracking of sudden onset after minor trauma, which is accompanied by persistent acute pain, rapid onset joint effusion and immediate functional impotence (intra-articular fracture or acute ligamentous/meniscal tear).
Standard management
- Glucosamine sulfate — 1500 mg once daily orally; chondroprotective with moderate long-term symptomatic efficacy
- Chondroitin sulfate — 800 mg once a day orally
- Intra-articular hyaluronic acid (high molecular density infiltration for viscosupplementation and cushioning of joint friction).
