The fibular collateral ligament (FCL) and popliteal tendon (PLT) are reconstructed in anatomic fashion according to techniques described by LaPrade et al.\n 3\u20137<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Description:<\/jats:title>\n \n Various PLC reconstruction techniques have been described; however, the preferred reconstruction technique of the senior author is the method developed by LaPrade et al. that restores the anatomy of the 3 primary stabilizers of the PLC, including the FCL, PLT, and popliteofibular ligament\n 3,5,6<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Alternatives:<\/jats:title>\n \n Alternative nonoperative treatments include knee immobilization for 4 weeks and physical therapy. Surgical alternatives include PLC repair, which involves repair of the lateral collateral ligament, PLT, and\/or popliteofibular ligament if structures can be anatomically reduced to their attachment site. However, repair of acute grade-III PLC injuries with staged treatment of concurrent cruciate injuries is associated with a substantially higher postoperative PLC failure rate\n 8\u201310<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Rationale:<\/jats:title>\n \n Clinical outcomes have demonstrated that primary repairs have significantly higher rates of reoperation compared with reconstruction; therefore, reconstruction is recommended. Treatment of grade-III PLC injuries with reconstruction of midsubstance tears and any associated cruciate ligament tears results in significantly improved objective stability\n 11<\/jats:sup>\n . In addition, anatomic PLC reconstruction has demonstrated improved subjective and objective patient outcomes compared with nonsurgical treatment or repair\n 5,11,12<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Expected Outcomes:<\/jats:title>\n \n Reconstruction of the PLC offers excellent outcomes after surgery. Studies have shown that the fibular-based technique for treatment of a chronic isolated PLC injury showed good results in terms of clinical outcome, restoring knee varus and rotational stability\n 13<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Important Tips:<\/jats:title>\n \n \n \n Patients with associated proximal tibiofibular joint instability will benefit from this reconstruction because this technique will add stability to the joint.<\/jats:p>\n <\/jats:list-item>\n \n This surgical approach is technically demanding, requiring proficiency with surgical dissection.<\/jats:p>\n <\/jats:list-item>\n \n Damage to the common peroneal nerve can potentially occur. Careful dissection and placement of retractors should be observed.<\/jats:p>\n <\/jats:list-item>\n \n \n Risks include surgical failure due to unrecognized malalignment; especially in chronic cases, the patient should have a complete evaluation of the standing alignment and tibial slope\n 12<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:list-item>\n <\/jats:list>\n <\/jats:p>\n <\/jats:sec>\n \n Acronyms and Abbreviations:<\/jats:title>\n \n \n \n FCL = fibular collateral ligament<\/jats:p>\n <\/jats:list-item>\n \n PFL = popliteofibular ligament<\/jats:p>\n <\/jats:list-item>\n \n PLC = posterolateral corner<\/jats:p>\n <\/jats:list-item>\n \n IT = iliotibial<\/jats:p>\n <\/jats:list-item>\n \n IKDC = International Knee Documentation Committee<\/jats:p>\n <\/jats:list-item>\n \n ACL = anterior cruciate ligament<\/jats:p>\n <\/jats:list-item>\n \n PCL = posterior cruciate ligament<\/jats:p>\n <\/jats:list-item>\n \n PEEK = polyetheretherketone<\/jats:p>\n <\/jats:list-item>\n \n PROM = passive range of motion<\/jats:p>\n <\/jats:list-item>\n <\/jats:list>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.2106\/jbjs.st.20.00047","type":"journal-article","created":{"date-parts":[[2022,1,7]],"date-time":"2022-01-07T16:00:20Z","timestamp":1641571220000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":8,"title":["Posterolateral Corner Reconstruction"],"prefix":"10.2106","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4685-6563","authenticated-orcid":false,"given":"Bhargavi","family":"Maheshwer","sequence":"first","affiliation":[{"name":"University Hospitals Cleveland Medical Center, Case Western Reserve University, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6500-6882","authenticated-orcid":false,"given":"Kevin C.","family":"Parvaresh","sequence":"additional","affiliation":[{"name":"Orthopaedic Specialty Institute, Orange, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6304-1916","authenticated-orcid":false,"given":"Brady T.","family":"Williams","sequence":"additional","affiliation":[{"name":"University of Colorado Medical Center, Denver, Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9707-3609","authenticated-orcid":false,"given":"Evan M.","family":"Polce","sequence":"additional","affiliation":[{"name":"University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9158-3528","authenticated-orcid":false,"given":"Daniel","family":"Schloss","sequence":"additional","affiliation":[{"name":"Midwest Orthopaedics at Rush, Rush University Medical Center, Chicago, Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9194-1150","authenticated-orcid":false,"given":"Jorge","family":"Chahla","sequence":"additional","affiliation":[{"name":"Midwest Orthopaedics at Rush, Rush University Medical Center, Chicago, Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,1]]},"reference":[{"issue":"2","key":"bib1-20240731","first-page":"97","article-title":"Posterolateral Corner of the Knee: Current Concepts","volume":"4","author":"Chahla","year":"2016","journal-title":"Arch Bone Jt Surg."},{"issue":"4","key":"bib2-20240731","doi-asserted-by":"crossref","first-page":"363","DOI":"10.1016\/j.rbo.2014.08.004","article-title":"Injuries to posterolateral corner of the knee: a comprehensive review from anatomy to surgical treatment","volume":"50","author":"Crespo","year":"2014","journal-title":"Rev Bras Ortop."},{"issue":"9","key":"bib3-20240731","doi-asserted-by":"crossref","first-page":"1386","DOI":"10.1177\/0363546504274143","article-title":"Mechanical properties of the posterolateral structures of the knee","volume":"33","author":"LaPrade","year":"2005","journal-title":"Am J Sports Med."},{"issue":"10","key":"bib4-20240731","doi-asserted-by":"crossref","first-page":"2069","DOI":"10.2106\/JBJS.G.00979","article-title":"The reproducibility and repeatability of varus stress radiographs in the assessment of isolated fibular collateral ligament and grade-III posterolateral knee injuries.
