Arthroscopic‐Assisted Intraosseous Bioplasty of the Acetabulum
Bibliographic record
Abstract
Intraosseous bioplasty (IOBP), has been previously described for arthroscopic-assisted treatment of subchondral bone cysts in the proximal tibia associated with early stages of knee osteoarthritis (OA). This technique entails combining bone marrow aspirate concentrate or concentrated platelet-rich plasma with demineralized bone matrix as a bone substitute before injecting into a subchondral bone defect under fluoroscopic guidance. The principles of IOBP as a procedure that combines core decompression with biologic bone substitute augmentation can be extended to treat subchondral bone marrow lesions such as acetabular and femoral cysts in degenerative hip OA. Intraosseous bioplasty of the hip, in particular the acetabulum, when done using this technique, is a useful alternative that can be beneficial in treating young patients with early hip arthritis to achieve successful outcomes while delaying more invasive procedures. The Technical Note described here presents a step-by-step approach, including tips and pearls for arthroscopic-assisted IOBP with decompression of the subchondral cyst in the acetabulum followed by bone substitute injection under fluoroscopic guidance. We believe this method is a safe and reproducible way to treat subchondral defects in young patients with signs of early osteoarthritis of the hip joint.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
