Comparison of open, percutaneous, or mini-open repair in the treatment of Achilles tendon ruptures: a systematic review and meta-analysis based on comparison studies
Bibliographic record
Abstract
Background: The Achilles tendon rupture is a common injury of the lower extremity, inducing pain and physical impairment. Surgical treatment methods include open, percutaneous, and mini-open repair techniques. This study aims to compare the outcomes of these three techniques. Methods: mini-open repair of the Achilles tendon rupture were included with at least one of the following outcomes: American Orthopedic Foot & Ankle Society (AOFAS) score, Achilles Tendon Total Rupture Score (ATRS) score, re-ruptures, sural nerve injuries, infections, wound dehiscence, deep vein thrombosis (DVT), and average operating time. Meta-analysis was mostly processed by RevMan 5. A P value of ≤0.05 was considered statistically significant. Risk of bias was assessed with RevMan 5 and the Newcastle-Ottawa scale. Results: Twenty-six studies, including 1,898 patients, were included. The percutaneous group had significantly more sural nerve injuries [risk ratio (RR) =0.28; 95% confidence interval (CI): 0.14 to 0.57; P<0.001], fewer infections (RR =2.99; 95% CI: 1.37 to 6.49; P=0.006), higher AOFAS score [standardized mean difference (SMD) =-0.32; 95% CI: -0.61 to -0.03; P=0.03], higher ATRS (SMD =-0.24; 95% CI: -0.47 to -0.02; P=0.03), and a shorter average operating period (SMD =2.29; 95% CI: 1.63 to 2.96; P<0.001) than the open repair group. The mini-open group had a significantly higher AOFAS score (SMD =-0.58; 95% CI: -1.06 to -0.09; P=0.02), higher ATRS (SMD =-0.65; 95% CI: -1.05 to -0.26; P=0.001), longer average operating time (SMD =-0.95; 95% CI: -1.46 to -0.45; P<0.001), and lower rates of re-ruptures and sural nerve injuries than the percutaneous group. The open group had significantly more infections than the mini-open group (RR =2.99; 95% CI: 1.07 to 8.37; P=0.04). Conclusions: The mini-open repair technique demonstrated superior function scores and lower complication rates than percutaneous repair and open repair. It should be the first choice when treating Achilles tendon ruptures, with percutaneous repair being a reliable alternative.

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.
