ObjectiveTo　investigate　the　application　value　of　arthroscopic　channel　modification　in　meniscal　injury　repair.　MethodsWe　retrospectively　analyzed　the　data　of　100　patients　with　meniscus　injuries　treated　with　knee　arthroscopy　from　December　2022　to　December　2023　and　divided　them　into　a　control　group　and　a　modified　group　according　to　the　application　of　＂arthroscopic　access　modification　technology＂.　We　compared　the　operation　time,　postoperative　hospitalization　time,　VAS　score,　Lysholm　knee　function　score,　postoperative　complications,　and　postoperative　images　of　the　patients　in　these　two　groups.　We　compared　the　operation　time,　postoperative　hospitalization　time,　pre-　and　postoperative　VAS　scores,　Lysholm　knee　function　scores,　postoperative　complications　and　postoperative　imaging　indices　of　the　patients　in　the　two　groups.　ResultsAll　patients　successfully　underwent　surgery　and　were　followed　up　without　intraoperative　vascular　or　nerve　injury　or　postoperative　complications　such　as　infection,　wound　necrosis　or　thrombosis.　The　average　follow-up　time　was　16.03　+/-　3.69　months;　the　average　operation　time　and　postoperative　hospitalization　time　of　the　modified　group　were　significantly　better　than　those　of　the　control　group　were　(P　＜　0.05);　the　pain　and　knee　function　of　the　two　groups　significantly　improved　over　time　(P　＜　0.05);　and,　compared　with　those　of　the　control　group,　the　modified　group　could　obtain　a　more　satisfactory　score　at　an　early　stage　of　the　postoperative　period　(P　＜　0.05),　and　the　comparison　of　the　intermediate　and　long-term　scores　of　the　two　groups　was　not　statistically　significant　(P　＞　0.05).　There　was　no　statistically　significant　difference　(P　＞　0.05).　ConclusionThe　improved　arthroscopic　access　technique　can　make　the　entry　and　exit　of　instruments　into　and　out　of　the　joint　cavity　smoother,　improve　the　surgical　field　of　view,　significantly　shorten　the　operation　time,　reduce　the　occurrence　of　intraoperative　complications,　improve　the　function　of　patients＇　knee　joints　earlier,　and　increase　their　satisfaction　with　the　operation.
