“…9 The popliteus tendon (PT) has historically been described as attaching 18.5 mm distal and anterior to the LCL origin; 9 however, studies out of Asia have demonstrated variation to this relationship with a more posteroinferior attachment of the PT in these populations. 10 Consistently, however, the PT can be found within the proximal 1/5th of the popliteal sulcus. 10 The PT courses medial to the LCL in a posteromedial direction where it becomes intra-articular, ultimately passing through the popliteal hiatus of the lateral meniscus.…”

Historically, the posterolateral corner (PLC) of the knee has been labelled as the “dark side” of the knee. The PLC is not a single structure but a confluence of multiple structures, including the lateral collateral ligament, popliteus muscle-tendon unit, and popliteofibular ligament. Understanding the individual components and their function is important to successfully identify these injuries. PLC injuries are commonly associated with cruciate injuries, and its early recognition is important to achieve successful outcomes. Injury to the PLC should be treated on a case-by-case basis, and an appropriate algorithm is required to manage them. Multiple surgical techniques ranging from primary repair to anatomic reconstruction have been reported in managing these injuries. We present the latest literature on the anatomy, biomechanics, clinical presentation, imaging, available techniques, and current management recommendations. There is a special focus on the pathoanatomy, which will help guide the treatment of these injuries.

Introduction Popliteal tendon impingement (PTI) is an under-recognized cause of persistent pain following total knee arthroplasty (TKA). The purpose of the systematic review was to summarize and outline successful strategies in the diagnosis and management of PTI. Methods A systematic review following the PRISMA guidelines was performed for four databases: MEDLINE (Pubmed), Ovid EMBASE, Web of Science, and Cochrane Database. It was registered in the International Prospective Register for Systematic Reviews and Meta-analysis (PROSPERO) under the registration number: CRD42023398723. The risk of bias assessment was performed using the criteria of the methodological index for non-randomized studies (MINORS). Results A total of 8 studies were included. There were 2 retrospective case series and 6 case reports. The follow-up ranged from 6 to 30 months. Two studies described PTI as an intraoperative phenomenon during TKA with “snapping”; whilst 6 studies described indications and outcomes for arthroscopic tenotomy for PTI following TKA. In making the diagnosis, there was concurrence that the posterolateral pain should be focal and that dynamic ultrasonography and diagnostic injection play an important role. Two specific clinical tests have been described. There was no consistency regarding the need for imaging. There were no reports of instability following popliteal tendon tenotomy or other complications. Conclusion PTI should be suspected as a cause for persistent focal pain at the posterolateral knee following TKA. The diagnosis can be suspected on imaging and should be confirmed with dynamic ultrasonography and an ultrasound-guided diagnostic injection. An arthroscopic complete tenotomy of the tendon can reliably alleviate pain and relies on correct diagnosis. There is no evidence for clinically relevant negative biomechanical consequences following tenotomy. Level of evidence Systematic Review of Level IV and V studies.
