postero lateral corner knee

J Murgier, P Boisrenoult, C Steltzlen, P Beaufils, N Pujol
Postero-lateral knee instability raises surgical challenges. Of the many available reconstruction techniques, few ensure anatomical reconstruction of the postero-lateral corner (PLC). The "Versailles" technique ensures the anatomical reconstruction of the three main PLC stabilisers (lateral collateral ligament, popliteus tendon, and popliteo-fibular ligament) by using either a hamstring autograft or a tendon allograft.

INTRODUCTION: Disengagement of polyethylene insert used in total knee arthroplasty is a rare but serious complication. Still rarer is disengagement because of failure of tibial insert locking mechanism. We report a previously unpublished complication of polyethylene insert locking mechanism failure in a 10-months-old posterior stabilized total knee arthroplasty in a 70-year-old woman with osteoarthritis for whom Attune (Depuy) knee implant was used. CASE PRESENTATION: A 70-year-old female underwent (Attune, Depuy) primary bilateral posterior stabilised total knee arthroplasty in a private hospital...

Tibiofemoral knee dislocation is a rare but serious limb-threatening injury. Without prompt recognition and management, amputation or long-term functional impairment may result. The authors present a case of bilateral sequential knee dislocation, secondary to low-energy trauma, in a patient with Systemic Lupus Erythematosus and antiphospholipid syndrome. Adequate stability was achieved on both occasions by reconstruction of the postero-lateral corner and MCL. During the first reconstruction, ipsi-lateral autograft, as well as hamstring tendons from the contra-lateral side, were used to strengthen the graft...

Postero-lateral corner of the knee is composed of several structures including the popliteo-meniscal fascicles (PMFs). These fibrous structures form a stable ligamentous complex around the popliteus tendon, which stabilize the lateral meniscus, increasing the strength of postero-lateral corner. Studies were retrieved through an electronic search of CINAHL, EMBASE, and Pub-Med, until May 2016. Studies in English, Italian, French, and Spanish were considered for inclusion. Randomized controlled trials, prospective and retrospective comparative studies, case series, and case reports were included...

OBJECTIVE: Minimally invasive ipsilateral semitendinosus reconstruction of large chronic tears aims to be advantageous for the patient in terms of plantar flexion recovery, anthropometric measures, fast return to daily and sport activity, is safe, with low donor site co-morbidities, low risks of wound complications and neurovascular injuries. INDICATIONS: Tendon gaps greater than 6 cm and in cases of revision surgery (rerupture). CONTRAINDICATIONS: Diabetes, vascular diseases, previous anterior cruciate ligament (ACL) reconstruction using ipsilateral semitendinosus tendon graft...

This study demonstrates the utility of a modified postero-medial surgical approach to the knee in treating a series of patients with complex tibial plateau injuries with associated postero-medial and postero-lateral shear fractures. Posterior coronal shear fractures are underappreciated and their clinical relevance has recently been characterised. Less-invasive surgery and indirect reduction techniques are inadequate for treating these coronal plane fractures. Our approach includes an inverted 'L'-shaped incision situated within the posterior flexor knee crease, followed by the retraction or incision of the medial head of the gastrocnemius tendon, while protecting the neurovascular structures...

INTRODUCTION: Posterior cruciate ligament (PCL) injuries are frequently associated with posterolateral corner (PLC) damages. These complex lesions are most often poorly tolerated clinically. Adherence to sound biomechanical principles treating these complex lesions entails obtaining a functional PCL and reconstructing sufficient posterolateral stability. HYPOTHESIS: Surgical treatment of postero-posterolateral laxity (PPLL) re-establishes sufficient anatomical integrity to provide stability and satisfactory knee function...

The aim of this study is to evaluate the effect of combined posterior cruciate ligament (PCL) and postero-lateral corner (PLC) reconstruction on laxity and three-dimensional kinematics of cadaver knees. We performed anatomical double bundle PCL reconstruction, and functional one bundle 'over-the-bottom' PCL reconstruction combined with one type of PLC reconstruction, running from the postero-lateral tibia to an isometric point near the lateral epicondyle of the femur. Our results showed that combined reconstruction was necessary to restore rotatory laxity...

Posterior cruciate ligament (PCL) rupture, whether or not combined with postero-lateral corner (PLC) tears, are more often diagnosed today thanks to improved imaging techniques. However, due to the lack of reliable instrumentation to quantitatively evaluate the knee, much is still unknown about the function of these ligamentous structures. The aim of this paper is to present results on the effect of progressive resection of the PCL and PLC on knee laxity and 3-D knee kinematics. The results show that 3-D movement analysis is important and complements laxity measurements by helping to interpret the complex alteration of knee function...

The use of fresh frozen tendon allografts is a well-documented surgical technique. We present a case where a harvested semitendinosus autograft was preserved by deep-freezing, having abandoned the initial procedure due to infection. After treatment of the infection the graft was subsequently used to reconstruct the postero-lateral corner complex with no deleterious effect at 1 year.

We treated 14 patients having knee instability and varus alignment with tibial osteotomy with or without ligament reconstruction. Five patients with varus angulated anterior cruciate deficiency (double varus) were treated with single-stage closed-wedge tibial osteotomy and anterior cruciate ligament reconstruction. The remaining nine patients had varying amount of posterior cruciate and postero-lateral corner ligament injuries with varus angulation (triple varus); six of these patients had a ligament reconstruction using the Ligament Advanced Reconstruction System ligament with tibial osteotomy (intra-articular--posterior cruciate ligament/extra-articular--postero-lateral corner reconstruction), while the remaining three had a tibial osteotomy without a ligament reconstruction...
