The Bioknotless Suture Anchor For The Treatment Of Shoulder Instability: Clinical Results
Bibliographic record
Abstract
PURPOSE: Arthroscopic treatment of symptomatic shoulder instability has become a well accepted procedure. Knotless suture anchors are one type of implant utilized for capsulolabral repair and have several advantages compared to other available devices. The use of these anchors, however, has been associated with unfavorable outcomes. The purpose of this study is to report our results of arthroscopically treated shoulder instability with a knotless, bioabsorbable suture anchor. METHODS: We identified and contacted patients who underwent arthroscopic capsulolabral repair of the shoulder with the BioKnotless anchor (DePuy Mitek, Raynam, Massachusetts). All patients had a minimum follow up of 2 years. Patient evaluation included a subjective questionnaire, physical exam, radiographs, and an MRI if indicated. All patients completed validated shoulder and health measurement outcome tools including the Simple Shoulder Test, the Short Form 12 Health Survey (SF-12), and the Western Ontario Shoulder Instability Index (WOSI). RESULTS: Eight patients were evaluated. The mean age was 28.9 years. There were 6 males and 2 females. The mean time to follow up was 33.6 months. No patients had any episodes of recurrent instability. When compared to the contralateral shoulder, patients lost an average of 2.5° of forward flexion, 6.3° of external rotation, and 11.3° of internal rotation. No patients had instability on physical exam as determined by apprehension, relocation or load and shift testing. Radiographic examination revealed no evidence of osteolysis, chondrolysis or degenerative changes. The mean WOSI score was 65.2% (out of 100%). The mean Simple Shoulder Test score was 10.4 (out of 12). The mean physical component to the SF-12 was 51.0 (population mean 52.5) and the mental component was 55.5 (population mean 53.1). CONCLUSIONS: Patients did report some level of disability of the shoulder determined by the WOSI, Simple Shoulder Test, and SF-12 scores. There was no radiographic evidence of osteolysis or glenohumeral arthritis. None of the patients reported any recurrence of instability. When properly utilized, the Bioknotless anchor remains a viable and safe option for successful treating symptomatic shoulder instability.

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.
