Quiet deep reading for appraised evidence. Library teaches from CSB; it does not replace CSB authority.

Primary surgery versus primary rehabilitation for treating anterior cruciate ligament injuries
22 min
Three RCTs comparing early ACL reconstruction with rehabilitation-first care: learn why no demonstrated functional superiority is not equivalence, and why this is a strategy comparison rather than surgery versus never surgery.
Design
Living systematic review + Bayesian random-effects meta-analysis of 3 randomized controlled trials
Source-level weight
Moderate for decision-level knee-function conclusion; Low for exact OA/meniscal/return-to-activity effects
Single-set versus three-set resistance training in women with patellofemoral pain
15 min
1 vs 3 progressive sets in resistance-training-naive women with PFP: what the trial says, what it cannot establish, and why the confidence interval matters.
Second ACL injuries in football players after ACL reconstruction
18 min
A football-specific prognosis meta-analysis: learn why 21.6% is a useful population anchor but not an individual risk estimate, and how prediction intervals change the interpretation.
Design
Systematic review + random-effects meta-analysis of 34 observational studies
Dutch multidisciplinary guideline on anterior knee pain: Patellofemoral pain and patellar tendinopathy
20 min
A multidisciplinary PFP/PT guideline: learn why low-certainty evidence can still support a recommendation and how to use 6/12-week reassessment without turning it into a rigid rule.
Long-term risk of knee replacement after ACL reconstruction using the contralateral knee as an internal control
20 min
A 135,881-patient cohort: learn why a roughly threefold relative risk can coexist with a low absolute risk, and why this design informs prognosis but not the causal effect of reconstruction.
Design
Population-based retrospective cohort with within-person contralateral-knee control
Source-level weight
High for prognostic association; not informative for ACLR treatment causality
Learning focus
Absolute vs relative risk · hazard ratio · within-person control · prognosis vs causality
