Coracoclavicular Ligament Reconstruction
Research Guide
What is Coracoclavicular Ligament Reconstruction?
Coracoclavicular ligament reconstruction is a surgical procedure using grafts, TightRope, or suture buttons to restore acromioclavicular joint stability in chronic dislocations.
Techniques focus on anatomic reconstruction for Rockwood type III-VI injuries. Studies report 85-95% return-to-sport rates with low complication profiles using suture button systems. Over 50 papers analyze outcomes in athletes, with Burkhart and de Beer (2000) providing foundational glenohumeral stability insights cited 1856 times.
Why It Matters
Restores shoulder stability for high-demand athletes, preventing chronic pain and instability after AC dislocations. Mihata et al. (2013) demonstrated 80% satisfaction in irreparable cuff cases, informing reconstruction choices. Neer et al. (1983) linked untreated instability to cuff-tear arthropathy, guiding prophylactic repairs in 26 patients.
Key Research Challenges
Graft Selection Variability
Allograft versus autograft choices impact healing rates and donor morbidity. Ellman et al. (1986) correlated repair difficulty with tissue quality in 50 rotator cuff cases. Optimal fixation remains debated for high-load activities.
Complication Rates Post-Reconstruction
Infections and re-ruptures occur in 5-15% of cases, linked to bone loss. Shaha et al. (2015) redefined critical glenoid loss thresholds for failure prediction. Long-term imaging follow-up is needed.
Return-to-Sport Outcomes
Athletes face 6-12 month recovery with variable success. Sirveaux et al. (2004) reported Constant score gains from 22.6 to post-op levels in 80 shoulders. Quantifying sport-specific stability remains challenging.

Reading Guide
Foundational Papers
Start with Burkhart and de Beer (2000) for bone defect failure mechanisms (1856 citations), then Neer et al. (1983) for cuff-tear pathology in 26 cases, as they underpin instability reconstruction principles.
Recent Advances
Study Shaha et al. (2015, 628 citations) redefining critical bone loss and Mihata et al. (2013, 827 citations) for arthroscopic capsule results.
Core Methods
Suture button fixation (TightRope), allograft weaving, arthroscopic portals; informed by Ellman et al. (1986) repair factors and Sirveaux et al. (2004) Constant scoring.
How PapersFlow Helps You Research Coracoclavicular Ligament Reconstruction
Discover & Search
Research Agent uses searchPapers and citationGraph on 'coracoclavicular reconstruction TightRope' to map 50+ papers from Burkhart and de Beer (2000), then exaSearch uncovers unpublished trials, while findSimilarPapers links to Mihata et al. (2013) for capsule techniques.
Analyze & Verify
Analysis Agent applies readPaperContent to extract Constant scores from Sirveaux et al. (2004), verifies claims with CoVe against Neer et al. (1983), and runs PythonAnalysis for meta-analysis of return-to-sport rates using GRADE grading on 10 high-citation studies.
Synthesize & Write
Synthesis Agent detects gaps in autograft complications via contradiction flagging across Ellman et al. (1986) and Shaha et al. (2015), then Writing Agent uses latexEditText, latexSyncCitations for 20 refs, and latexCompile to generate outcome tables with exportMermaid for reconstruction flowcharts.
Use Cases
"Analyze complication rates in CC ligament reconstruction via Python meta-analysis"
Research Agent → searchPapers → Analysis Agent → runPythonAnalysis (pandas meta-analysis of rates from 15 papers) → statistical summary with p-values and forest plots.
"Draft LaTeX review on TightRope vs grafts for AC dislocation"
Synthesis Agent → gap detection → Writing Agent → latexEditText + latexSyncCitations (Burkhart 2000 et al.) + latexCompile → PDF with cited outcome diagrams.
"Find open-source code for simulating CC ligament tension"
Research Agent → paperExtractUrls → Code Discovery → paperFindGithubRepo → githubRepoInspect → validated biomechanics model for TightRope stress testing.
Automated Workflows
