Medial sprains, accounting for 3%–4% of ankle injuries, are frequently misdiagnosed, leading to chronic pain, instability, and hindfoot valgus deformity. While most cases respond to conservative treatment, chronic injuries that fail conservative measures require surgical intervention.

Comparative clinical studies were included if they conducted a comparative analysis on the clinical outcome of SA-ACLRep versus ACLR with a minimum of 2 years of follow-up (FU). The primary outcome was ACL re-rupture rate; secondary outcomes included complications, knee stability (arthrometer measurements), patient-reported outcome measures (PROMs) and return-to-sport. A random effects model (based on the restricted maximum likelihood method) was used for all pooled analyses.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Four studies met the inclusion criteria and included 687 patients (276 SA-ACLRep and 411 ACLR). There was no statistically significant difference between the two groups in terms of re-rupture rates (11.5% with SA-ACLRep and 8.4% with ACLR; &lt;i&gt;p&lt;/i&gt; = 0.094). PROMs, including International Knee Documentation Committee, Knee injury and Osteoarthritis Outcome Score subscales, Lysholm, visual analogue scale pain, Single Assessment Numeric Evaluation and Tegner scores, showed no significant differences between SA-ACLRep and ACLR. No significant differences were found in return to sport rates (72.3% with SA-ACLRep and 65.0% with ACLR; &lt;i&gt;p&lt;/i&gt; = 0.541) or timing (mean difference = −0.93 months [95% confidence interval: −2.54, 0.69]; p = 0.261).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;SA-ACLRep with internal bracing and ACLR showed comparable short-term (≥24 months) FU results, with no statistically significant differences observed in re-rupture rates, PROMs or return-to-play rates. This may suggest that SA-ACLRep may be a viable alternative for appropriately indicated proximal ACL tears. Heterogeneity in study design, the small number of studies included, the repair timing and reconstruction techniques limit the generalizability of the results.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000","PeriodicalId":36909,"journal":{"name":"Journal of Experimental Orthopaedics","volume":"12 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esskajournals.onlinelibrary.wiley.com/doi/epdf/10.1002/jeo2.70404","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144934957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the Forgotten Joint Score (FJS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) are established measures of patient satisfaction and functional outcomes after TKA, they may not directly capture the patient's subjective perception of the joint itself.
