Outcomes of comparative studies.
| Author | LOE | Comparison | Outcomes |
|---|---|---|---|
| Nie S (2021) | III | HP vs. SBC | SBC group significantly less skin incision, hospitalization, and blood loss SBC group significantly better VAS and Constant |
| Shen G (2021) | III | HP vs. SBC | No significant difference in VAS, UCLA, or Constant |
| Yoo Y (2021) | IV | HP vs. multiple suture anchors | Suture anchors better ASES, SPADI, QuickDASH, and CC distance |
| Seo JB (2020) | III | HP vs. HP + CC ligament repair | No difference in ASES, Constant, or CC distance No difference in timing of implant removal HP + CC repair had lower CC distance ratio than HP alone |
| Wang YC (2020) | IV | SBC: Twin Tail Tightrope (TTR) vs. SBC: Endobutton | TTR group smaller incision length, shorter operative times, less blood loss No difference in Constant or CC distance |
| Lee (2019) | IV | Tendon construct vs. SBC | No significant difference in ASES, SANE, or loss of reduction |
| Seo (2019) | III | SBC (tunnel first) vs. SBC (reduction-first) | KSS better in reduction-first Less loss of coracoclavicular distance ratio in reduction-first Smaller coracoclavicular tunnel width in reduction-first group No difference in ASES |
| Bin Abd Razak (2018) | III | HP vs. SBC | Longer operative time in SBC group SBC group better Constant and CC distance at 1 year No difference in VAS |
| Stein T (2018) | II | HP vs. SBC | SBC group better Taft, Constant, and NAS No difference in CC distance |
| Yin J (2018) | II | HP w/double-tunnel CC reconstruction vs. HP alone | Reconstruction group longer incision length and operative time Reconstruction group better VAS, Constant, ASES, and satisfaction rate |
| Zheng J (2018) | II | HP vs CC Screw (supplemented with K wire) | CC screw shorter operative time, smaller incision, less blood loss, shorter hospitalization CC screw better VAS scores No difference in Constant or CC distance |
| Cisneros N (2017) | IV | HP vs. nonoperative management | No difference in SF-36 (mental), SF-36 (physical), VAS, DASH, Constant, or satisfaction 100% of non-operative patients had complete separation at final follow-up, compared to 36% in the hook plate group |
| Cho (2016) | III | SBC (trans-spinal pin) vs. SBC (trans-articular pin) | No difference in ASES, UCLA, or subjective shoulder score |
| Metzlaff S (2016) | III | HP vs. SBC | No significant difference in Constant, Taft, ACJI, or CC-distance |

| Gao Y (2015) | IV | HP vs. single multistrand titanium cable (MSTC) | MSTC group better Constant |
| Yoon J (2015) | IV | HP vs. CC ligament reconstruction | No difference in VAS or Constant HP greater reduction in CC distance |
| Jensen G (2014) | III | HP vs. SBC | No significant difference in VAS, SST, Constant, Taft, or CC distance |
| Horst (2013) | III | SBC vs. k Wire | No difference in CC distance |
| Mardani-Kivi M (2013) | III | Semitendinosus (ST) autograft vs. suture fixation | No difference in Constant scores No difference in VAS scores during rest or routine daily activity ST autograft group better VAS during intense activity |
| von Heideken J (2013) | IV | Acute vs. delayed HP | No difference in Constant Acute group better SPADI, QuickDASH, SSV Acute group less pain at rest and during movement |
