MID-TERM EFFECTIVENESS OF OXFORD UNICOMPARTMENTAL KNEE SYSTEM PHASE III FOR MEDIAL UNICOMPARTMENTAL KNEE OSTEOARTHRITIS
Bibliographic record
Abstract
Objective To evaluate the mid-term effectiveness of Oxford Unicompartmental Knee system Phase III for medial unicompartmental knee osteoarthritis(OA).Methods Between December 2008 and August 2010,26 patients(32 knees) with medial unicompartmental knee OA were treated.Of 26 patients,11 were followed up more than 2 years,including 7 males and 4 females(14 knees,6 left and 8 right knees) with an average age of 62.4 years(range,50-74 years).All patients had load suffering and tenderness of medial unicompartmental knee,and complicated by varus deformity without limitation of flexion and extension;the disease duration ranged 5-23 years(mean,11.6 years).According to Ahlback staging,4 knees were at stage II and 10 knees at stage III.Cemented unicompartmental knee arthroplasty(Oxford Unicompartmental Knee system Phase III) was performed by minimally invasive technique.Results All the incisions were primary healing after operation.Five cases suffered from local ache in the pes anserinus during the first 3 months after operation,which was cured after conservative therapy.Of them,11 patients were followed up 27.5 months on average(range,24-30 months).During follow-up,no complication of prosthesis loosening,displacement,arthropathy in the opposite department,or the patellofemoral joint occurred.The range of motion was significantly improved from(109.2 ± 8.7)° preoperatively to(123.5 ± 6.7)° at last follow-up(P 0.05);knee society score(KSS) and Western Ontario and McMaster University Osteoarthritis Index(WOMAC) scores were all significantly improved(P 0.05).At last follow-up,the femoro-tibial angle was significantly improved(P 0.05);tibial plateau and the tibial anatomical axis increased,showing no significant difference(P 0.05);and posterior tibial slope was significantly decreased(P 0.05).Conclusion Oxford Unicompartmental Knee system Phase III has satisfactory mid-term effectiveness in treating medial unicompartmental knee OA with the advantages of little trauma and rapid recovery,but long-term effectiveness is expected for further follow-up.

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.
