This is a two-patient case report of severe glenohumeral chondrolysis after arthroscopic thermal capsulorrhaphy for shoulder instability. Both patients were young athletes with normal cartilage at the index procedure. The report asks whether thermal energy used on the capsule can cause catastrophic cartilage loss.
When a young instability patient returns months after arthroscopy with worsening pain, stiffness, and joint space loss on imaging, put chondrolysis high on the differential.
The key teaching point: cartilage was normal at surgery and never touched thermally, yet both joints were destroyed within a year. This implicates the thermal energy and fluid environment near the capsule, not direct chondroplasty. The workup matters. Normal WBC, ESR, CRP and negative cultures separate chondrotoxic chondrolysis from septic arthritis, which drives very different management.
For salvage in a patient in their teens or twenties, standard total shoulder arthroplasty is a poor choice because of glenoid polyethylene loosening. Biologic glenoid resurfacing with meniscal allograft plus humeral resurfacing preserves bone stock. Historically, reports like this contributed to thermal capsulorrhaphy falling out of favor for shoulder instability.
