The recovery process typically spans 9 to 12 months, delineated in a phased, criterion\u2010based approach to monitor milestones, restore function and confidence, and promote return to sport. The early phase (weeks 0\u20106) focuses on reducing pain and swelling while restoring knee range of motion (ROM) and quadriceps strength (\u226560% limb symmetry index [LSI]) with the use of modalities such as neuromuscular electrical stimulation. Open kinetic chain exercises can be initiated after surgeon clearance and appropriate progression to safely load the quadriceps without placing excessive strain on the reconstructed ACL. The intermediate phase (weeks 7\u20109) commences when the early\u2010phase goals of knee ROM of 0\u00b0 to 115\u00b0, effusion of 1+ or less, and a normalized gait pattern are achieved. This phase focuses on initiating balance activities, neuromuscular re\u2010education, and aerobic training. Key goals of this phase include full, symmetrical ROM and quadriceps strength with an LSI of 70% or greater, which is achievable when adhering to a structured, progressive overload strength training program. The late phase (weeks 10\u201016) introduces running when quadricep strength reaches an LSI of 80% or greater and emphasizes training of proper landing mechanics. Strength training is progressively advanced and transitioned to a more intensive, gym\u2010based program with a target LSI of 75% to 80% or greater. The transitional phase (months 4\u20106) initiates jumping, sprinting, decelerating, and agility drills. Goals include an LSI for quadriceps strength and hop testing of 85% or greater. The return\u2010to\u2010sport phase (months 6\u201012) emphasizes sport\u2010specific drills and conditioning in preparation for return to competition. Clearance for full return to sport and competition should be provided when there is no pain or effusion, the patient attains an LSI for quadriceps strength and hop testing of 90% or greater, and fear\/confidence levels are evaluated. This phased rehabilitation approach with criterion\u2010based objective milestones allows patients to safely return to sport at preinjury levels while minimizing risk of reinjury.<\/jats:p>","DOI":"10.1016\/j.arthro.2025.08.001","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T00:13:13Z","timestamp":1764202393000},"page":"4393-4395","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":8,"title":["Recovery Stages After Anterior Crucuiate Ligament Reconstruction"],"prefix":"10.1002","volume":"41","author":[{"given":"Stephanie C.","family":"Petterson","sequence":"first","affiliation":[{"name":"Orthopaedic Foundation Stamford Connecticut U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael C.","family":"Buckmire","sequence":"additional","affiliation":[{"name":"University of Delaware Newark Delaware U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Airelle O.","family":"Giordano","sequence":"additional","affiliation":[{"name":"University of Delaware Newark Delaware U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,1]]},"reference":[{"key":"e_1_2_2_2_1","unstructured":"ArhosE.K.
