ARTICLE HIGHLIGHTS
Research background

Intra-articular osteoid osteoma of the knee is a rare entity that may present with non-specific symptoms and may lead to severe disability if left untreated. There are several treatment options, one of which is arthroscopic removal.

Research motivation

As there is a low number of reported cases of intra-articular osteoid osteoma of the knee, our goal was to report our results and further elaborate on the results available in the literature.

Research objectives

To analyze whether arthroscopic removal is an effective treatment option for intra-articular osteoid osteoma of the knee.

Research methods

A first case series ever of such patients was reported, as well as the review of all available cases in the literature that report on the same pathology and treatment options.

Research results

Both the case series and cases from the literature report that arthroscopic removal of intra-articular osteoid osteoma is an effective treatment option with a low chance for recurrence of the disease.

Research conclusions

Arthroscopic removal of intra-articular osteoid osteoma enables excision that is neither insufficient nor excessive, thus avoiding both recurrence of the disease, as well as chondral lesions and bone necrosis, while obtaining adequate material for histopathologic analysis. Therefore, it should be considered as a treatment option if physicians come across such a case.

Research perspectives

Future research will additionally clarify the efficiency of arthroscopic removal of intra-articular osteoid osteoma, possibly on a larger case series than reported in this article and in the literature so far.
