Cement and screw reconstruction for Rand type II bone defects during total knee arthroplasty: a retrospective clinical and radiographic evaluation
Bibliographic record
Abstract
OBJECTIVE: To investigate the clinical and radiographic results of cement and screw reconstruction for bone defects during total knee arthroplasty(TKA). METHODS: From September 2014 to September 2019, 38 patients with Rand type II bone defects who underwent the screw plus cement technique during primary TKA were included in this study. The clinical results were evaluated via the Knee Society Knee Scale (KSKS), Knee Society Function Scale (KSFS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and range of motion (ROM). The hip-knee-ankle angle (HKAA), femorotibial angle (FTA), and radiolucent lines were assessed radiologically. RESULTS: Thirty-five patients were followed up for an average of 92.6 months (60-120 months). At the last follow-up visit, the KSKS, KSFS, WOMAC score, and ROM were significantly improved. The HKAA and FTA were corrected postoperatively. In 3 patients, a nonprogressive radiolucent line measuring approximately 1 mm was observed at the interface between the host bone and the cement at 3, 6 and 12 months after surgery, with an incidence of 8.3%, No radiolucent lines were found around the screws and no infection, fracture or prosthesis loosening occurred at the last follow-up visit. CONCLUSION: Cement and screw reconstruction for Rand type II bone defects during TKA achieved satisfactory clinical and radiological results and solid fixation. This could be considered an economical and practical method to repair mild and moderate bone defects in primary TKA patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
