Abstract

Background and purpose - Tenosynovial giant cell tumors (t-GCTs) can behave aggressively locally and affect joint function and quality of life. The role of arthroplasty in the treatment of t-GCT is uncertain. We report the results of arthroplasty in t-GCT patients. Patients and methods - t-GCT patients (12 knee, 5 hip) received an arthroplasty between 1985 and 2015. Indication for arthroplasty, recurrences, complications, quality of life, and functional scores were evaluated after a mean follow-up time of 5.5 (0.2-15) years. Results - 2 patients had recurrent disease. 2 other patients had implant loosening. Functional scores showed poor results in almost half of the knee patients. 4 of the hip patients scored excellent and 1 scored fair. Quality of life was reduced in 1 or more subscales for 2 hip patients and for 5 knee patients. Interpretation - In t-GCT patients with extensive disease or osteoarthritis, joint arthroplasty is an additional treatment option. However, recurrences, implant loosening, and other complications do occur, even after several years.

Figures

Figure 1.
Figure 1.
Gradient-echo-based MRI image from a patient with recurrent t-GCT (right knee). There was very low signal intensity corresponding to hemosiderin depositions anterior to the lateral meniscus, extending to the infrapatellar fat pad. Furthermore, there was a hemosiderin deposition in the recessus lateralis posterior to the lateral femoral condyle. These localizations corresponded to recurrent Dt-GCT, which was confirmed by surgical removal.

Gradient-echo-based MRI image from a patient with recurrent t-GCT (left knee). There was very low signal intensity corresponding to hemosiderin depositions, particularly in the posterior compartment of the joint and in the popliteal fossa. There was also osseous destruction.
