Diffuse-type tenosynovial giant-cell tumours of the knee (D-TGCT) have a very high complication rate.
-
The recurrence rate for D-TGCT is mainly dependent on an initially successful resection of the lesion.
-
The standard of care for this disease involves early surgery with synovectomy. Available surgical techniques may include an arthroscopic or open surgery; however, there is a lack of consensus on which technique should be used, and when.
-
Arthroscopic excision is effective in minimizing morbidity and surgery-related complications, while an open surgical technique provides a more successful resection with a lower incidence of local recurrence.
-
We could not conclude with confidence which of the surgical techniques is better at stopping a progression towards osteoarthritis and the need for a total knee arthroplasty.

Giant cell tumour of bone (GCT) is a relatively rare, locally aggressive benign neoplasm observed in the long bone epiphyseal-metaphyseal regions of young adults.
-
The optimal treatment strategy for these tumours remains controversial, and a huge amount of contradictory data regarding the functional and oncological outcomes can be found. Therefore, we performed a systematic review intended to investigate the functional and oncological outcomes after surgical treatment of GCTs arising around the knee, namely in the distal femur and proximal tibia.
-
A trend towards better oncological control was found using wide resections, nonetheless, curettage-based techniques achieve a highly acceptable recurrence rate with overall better knee function. A slight advantage favouring proximal tibia GCTs regarding the Musculoskeletal Tumor Society (MSTS) score was also observed.
-
Prospective studies comparing groups of more homogeneous patients, tumours, and treatment options should be developed to obtain more conclusive and definitive results regarding the optimal strategy for treating GCTs.
