Arthroscopic treatment of mucoid degeneration of the anterior cruciate ligament
Bibliographic record
Abstract
Objective The purpose of this study was to examine the clinical features, radiological and arthroscopic characteristics of mucoid degeneration of the anterior cruciate ligament (ACL) and to assess the results of arthroscopic treatment. Methods From January 2012 to August 2013, 32 knees (24 females and 8 males with left knee of 14 and 18 of right) were diagnosed with mucoid degeneration of the ACL and underwent arthroscopic treatment, all of whom with a mean age of 58.81±7.97 years (42-74 years). All 32 patients have pain on terminal extension, in which 12 patients have pain on both terminal flexion and extension. Arthroscopic debridement of hypertrophied ACL was performed in conjunction with notchplasty. Biopsy specimens were taken from yellowish degenerative lesions of ACL posterolateral bundles. Manual Lachman and Anterior Drawer tests were taken or measured preoperatively, as well as, visual analogue scale (VAS), range of motion (ROM) of knee, Lysholm scores, Western Ontario and McMaster Universities (WOMAC) scores. Results The narrow intercondylar notch show in all 32 radiographs and sagittal magnetic resonance image showing with its attachment thickened and ill-defined ACL. All patients received follow-up. The mean follow-up time was 21.16±5.53 months (15- 32 months). The mean VAS score decreased significantly from 5.75±1.32 to 1.13±1.36 (t=13.44,P=0.00). Extension deficits decrease gradually from a mean angle of 11.62°±3.52° preoperatively. Almost stable 6 months postoperatively and the mean score was 0.41°±1.01° 1 year after operation. The extension deficit improved significantly. Manual Lachman tests and Anterior Drawer tests were all negative. At the same time, Lysholm scores increased from 50.13±11.57 to 91.97±3.04 and WOMAC scores decreased from 35.13±7.88 to 6.25±2.78, which is statistically significant (t=-20.20,P=0.00;t=24.72,P=0.00). Conclusion Mucoid degeneration of the ACL has a typical clinical feature and the MRI findings are fairly specific for clinical diagnosis before arthroscopy. Arthroscopic debridement of mucoid hypertrophy of the ACL in conjunction with notchplasty can effectively provide symptomatic improvement without instability.

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.
