These pathophysiological changes not only intensify postoperative pain but also compromise the intra-articular environment via mechanical compression and localised microcirculatory deficits, thereby impeding recovery. Conventional interventions for postoperative swelling, such as cryotherapy and physical agent modalities, are commonly applied yet exhibit limited efficacy. Multilayer low-stretch bandage (MLB), with its gradient compression properties, has recently demonstrated superior swelling control and functional restoration; however, existing research primarily assesses short-term outcomes and lacks a systematic analysis across the postoperative continuum\u2014acute, subacute and chronic phases\u2014as well as long-term follow-up. This study therefore employs a multi-temporal intervention design and extended follow-up to evaluate the effectiveness of MLB in managing swelling, modulating pain and enhancing long-term knee function and activities of daily living across different recovery stages. The findings aim to furnish high-level evidence for knee rehabilitation protocols, refine clinical practice and ultimately improve patient quality of life.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>This prospective, single-blind, randomised controlled trial will enrol 36 patients following ACLR and patellar fracture. Participants will be allocated at a 1:1 ratio through computerised randomisation to either an experimental group receiving MLB plus conventional rehabilitation, or a control group receiving conventional rehabilitation alone. The study spans 12 weeks, with follow-up assessments scheduled at baseline (T0), 4 weeks (T1), 8 weeks (T2) and 12 weeks (T3). Outcome measures comprise the Hospital for Special Surgery (HSS) Knee Rating Score, affected limb oedema regression rate, Visual Analogue Scale (VAS) pain score, knee range of motion, quadriceps and hamstring muscle strength, centre of pressure (COP) displacement parameters, proprioceptive testing, the 36-Item Short Form Health Survey (SF-36) and the Holden Walking Function Classification. A subsequent 1-year follow-up will assess long-term efficacy and patient satisfaction, while adverse events are strictly monitored throughout the entire study period. Adherence to Consolidated Standards of Reporting Trials guidelines is maintained, and a single-blind design ensures that both participants and assessors remain unaware of group assignments. This trial aims to establish an evidence-based foundation for optimising postoperative rehabilitation in this patient population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>Ethical approval for the study was obtained from the Medical Ethics Committee of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School (2025-0141-01).
