Meta-Analysis
PURPOSE
To evaluate safety and efficacy of percutaneous ablative therapy for the treatment for osteoid osteomas.
MATERIALS AND METHODS
PubMed database, Web of Science, and SCOPUS were searched from their inception until November 2019 for articles describing osteoid osteoma. Demographic data, success rates, pre- and post-procedure VAS scores, and complications were recorded. A random-effects meta-analyses of the VAS pain score at various time points were calculated.
RESULTS
For radiofrequency ablation, VAS scores for pain at pre-procedure, 24-48 h, and 3-6 months yielded cumulative pain scores of 7.64 +/- 0.175, 0.78 +/- 0.186, and 0.02 +/- 0.0196, respectively. For cryoablation, VAS scores at pre-procedure, 24-48 h, and 3-6 months yielded cumulative pain scores of 8.46 +/- 0.549, 0.975 +/- 0.66, and 0.112 +/- 0.08, respectively. For laser ablation, VAS scores at pre-procedure and 24-48 h yielded cumulative pain scores of 4.94 +/- 1.42, and 0.506 +/- 0.268, respectively. For microwave ablation, VAS scores at pre-procedure, 24-48 h, and 3-6 months yielded cumulative pain scores of 6.14 +/- 1.07, 1.636 +/- 1.215, and 0 +/- 0.0, respectively. All ablation methods resulted in significant immediate and lasting pain reduction (p < 0.001). Technical and clinical success rates and major complications for RFA, microwave ablation, laser ablation, and cryoablation did not differ significantly. Overall recurrence of bone pain at the same site occurred in 4.06% of all patients an average of 11 months post-procedure.
CONCLUSION
Percutaneous ablative therapies are safe and result in significant and lasting pain reduction as demonstrated through visual analog scale pain scores.

OBJECTIVE
Magnetic resonance-guided focused ultrasound (MRgFUS) is a novel noninvasive interventional technique for osteoid osteoma (OO). The purpose of this study was to evaluate the efficacy and safety of MRgFUS in the treatment of OO through a systematic review and meta-analysis of pain scores and post-treatment adverse events before and after MRgFUS treatment.
MATERIALS AND METHODS
A comprehensive literature search of PubMed, Embase, Web of science, and Cochrane Library databases was conducted to screen the study literature based on inclusion and exclusion criteria to extract and analyze pre- and post-treatment pain score data, success rates (complete pain relief with no recurrence until the last follow-up), recurrence rates, secondary intervention rates, and complications to evaluate the efficacy and/or safety of MRgFUS for OO.
RESULTS
A total of 113 studies published between 2012 and 2022were collected, resulting in a total sample size of 353 patients. The majority of the studies were prospective and had a follow-up period of 4 weeks or more, and overall, the quality of evidence ranged from low to high. Pain scores at 1 week and 1 month after the merger were 0.62 (9.5% CI:0.28-0.96) and 0.37 (9.5% CI:0.07-0.68), respectively. The success rate of the combination was 92.8% (95% CI: 89.8%-95.7%), the incidence of minor complications (thermal injury at the ablation site) was 0.85%, and no major complications were recorded in any of the included literature.
CONCLUSION
MRgFUS is an effective procedure that is able to treat pain for patients with OO with satisfying efficacy and safety.

Meta-Analysis
BACKGROUND
Osteoid osteomata comprise approximately 10% of benign bone tumours, with 20% of them being located in the proximal femur and 1-3% in the pelvis. In this meta-analysis, we sought to investigate positive and negative outcomes relating to minimally invasive surgery (MIS), which has superseded open resection and conservative measures over the last decades.
METHODS
We searched the PubMed, CENTRAL and grey literature for completed studies published until 10 August 2020. Articles with a minimum of ten patients diagnosed with osteoid osteomata of the proximal femur and/or acetabulum were included. Primary outcomes were success rates, complications and recurrences following treatment. Delays in diagnosis were also recorded. We conducted random effects meta-analysis of success rates for MIS modalities using MedCalc statistical software. Quality was assessed with a modified Delphi checklist.
RESULTS
Sixteen case-series were identified. Success rates for computed-tomography (CT)-guided radiofrequency ablation (RFA), CT-guided percutaneous resection drilling and arthroscopic resection were 98.2% (95% CI 95.8-99.5), p = 0.47; 91.5% (95% CI 81.1-97.9), p = 0.06; and 98% (95% CI 89.3-99.7), p = 0.95, respectively. Both RFA and percutaneous drilling resection were associated with two iatrogenic femoral fractures. Arthroscopic removal was not associated with any complications. Definitive diagnosis was established at least six months after symptom onset in up to 43% of patients.
CONCLUSIONS
RFA could be the most effective treatment options for patients suffering from osteoid osteomata of the hip. Arthroscopy could be potentially as effective as RFA as long as further large-scale studies confirm its efficacy and safety. Reported complications stemming from these modalities were sparse in nature. In order to avoid inordinate diagnostic delays, a high index of suspicion and low threshold for CT scan investigation is required.

OBJECTIVES
CT-guided radiofrequency ablation (CT-RFA) is considered to be the gold standard for treatment of osteoid osteoma (OO) yet treatment failures (TFs) continue to be reported. This systematic review was conducted to evaluate factors associated with TF, such as ablation time, lesion location, and patient age as well as evaluating how TF has trended over time.
METHODS
Original studies reporting on patients undergoing CT-RFA of OO published between 2002 and 2019 were identified. TF was defined as patients with (1) recurrent or persistent pain +/- (2) imaging evidence of persistent OO. TFs were subdivided into those occurring after the index procedure (primary TF) or those occurring after repeat RFA (secondary TF). Subgroup analysis was performed for TF based on the study date (2002-2010 or 2010-2019), time duration of ablation at 90 °C (6 min or > 6 min), patient age, and tumor location (spinal vs. appendicular).
RESULTS
Sixty-nine studies were included for a total of 3023 patients. The global primary TF rate was 8.3% whereas the secondary TF rate was 3.1%. The TF rate reported in studies published after 2011(7%) was about half that during the earlier time period 2002-2010 (14%). There was no statistical difference in TF corrected for age, OO location, or duration of ablation (respectively p = 0.39, 0.13, and 0.23). The global complication rate was 3%, the most frequent being skin burns (n = 24; 0.7%).
CONCLUSIONS
A decrease in TF observed between 2011-2019 compared to 2002-2010 may reflect improvements in operator technique or advancements in equipment. Duration of ablation, patient age, or location of OO failed to significantly correlate with TF.
KEY POINTS
• CT-guided radiofrequency ablation of osteoid osteomas is a safe technique with a low rate of treatment failure (8.3% failure rate after the primary radiofrequency reducing to 3.1% following a secondary treatment). • The treatment failure rate has decreased over time, possibly due to an improved understanding of the disease process, better technique, and advances in equipment. • Duration of ablation, patient age, or lesion location did not significantly correlate with treatment failure.

INTRODUCTION
Patellar involvement by osteoid osteoma is very rare. Osteoid osteomas that present as anterior knee pain are frequently misdiagnosed which leads to initial delay in treatment. Plain radiology has poor diagnostic yield. A combination of high index of suspicion, appropriate imaging, and complete ablation of the lesion is necessary to achieve good outcomes.
CASE REPORT
A 16-year-old male presented with insidious onset anterior knee pain for the past 2 years. The pain was intermittent and mild; however, it increased progressively in intensity and frequency, which was worse at night. Examination reveals minimal effusion in the suprapatellar pouch, full range of motion of the knee, and wasting of the quadriceps. Serum biochemistry parameters were in normal limits. Plain radiographs did not reveal any significant abnormality. On magnetic resonance imaging, a hypointense, punctate lesion surrounded by a small hyperintense zone was noted at medial aspect of patella. A computed tomography scan showed the lesion with a central nidus, surrounded by a sclerotic rim, confirming the diagnosis of osteoid osteoma. Radiofrequency ablation was carried out without any post-procedural complications. The patient was pain free a few days after the procedure. At 14-month follow-up, there was no recurrence of symptoms.
CONCLUSION
Osteoid osteomas that present as anterior knee pain are frequently misdiagnosed. Plain radiology has poor diagnostic yield. A combination of high index of suspicion, appropriate imaging, and complete ablation of the lesion is necessary to achieve good outcomes.
