RESUMO
TruFit plugs (Smith & Nephew, Andover, MA) are synthetic polymer scaffolds that are inserted into an articular surface to provide a stable scaffold to encourage the regeneration of a full thickness of articular cartilage to repair chondral defects. Our unit has shown promising early results for the repair of small articular cartilage defects within the knee. Other series have reported "failures" in which patients have complained of persistent symptoms and joint effusion at 6 months after plug insertion and arthroplasty has been undertaken. We report a case of delayed incorporation of an articular cartilage defect of the lateral femoral condyle treated with 3 TruFit plugs. The patient eventually reported symptom alleviation and resumption of functional activity after 24 months of continued rehabilitation. We recommend that patients with continued symptoms persevere with rehabilitation and allow the regenerating articular cartilage time to mature fully before considering undertaking irreversible arthroplasty procedures.
