“…Interestingly, after fracture fixation, the joint was stable in physical examination (negative anterior/ posterior drawer test, negative varus/ valgus stress test) and no gross ligament injury was detected. There is a case report in the literature describing a posteromedial knee fracture dislocation scenario with no knee ligament injury [ 12 ]. We think our patient’s associated articular fractures may protected knee ligaments from severe damage.…”

Background Open knee fracture-dislocation is a rare orthopedic injury. However, the importance of its correct management could not be overstated. To the best of our knowledge, this is the fifth study reporting a case with simultaneous Hoffa fracture and knee dislocation and the 1st study describing a patient with open plateau fracture-dislocation accompanied with Hoffa fracture, patella fracture, and patellar tendon tear. In addition, this report is noticeable as our case had no gross ligament injury unlike frequent association of knee dislocation with knee collateral ligament damage. Case presentation In this study, we describe a 34-year-old motorcyclist referred to our center following a motor car accident. Further work-up revealed an open irreducible posterolateral knee dislocation, type 5 Hohl and Moore plateau fracture, lateral femoral condyle Hoffa’s fracture, patellar fracture, and patellar tendon tear of his right knee. During an open reduction, it turned out that an entrapped lateral meniscus prevented the joint to be reduced by closed means. After applying a temporary external fixator, the patient was finally managed with open reduction and internal fixation. Conclusion Irreducible knee dislocation needs further work up to rule out any interposed soft tissue into the joint. Aggressive irrigation/ debridement, early anatomic reduction, and internal fixation may help reduce open fracture complications including infection, non-union, and stiffness.

“…After 1 month, the patient underwent another operation in order Figure 5B. X-ray: LL view the surgical repair and then bone stabilization (14) The second factor is the association between knee dislocation and open fractures (15). The third factor is represented by irreducible dislocation of the knee (16,17).…”

Introduction. Traumatic knee dislocation is a serious lesion which represents an orthopaedic emergency. It is a rare condition that requires appropriate diagnosis-therapeutic iter. Case report. A 63 year old male was admitted to the emergency department after an agricultural vehicle accident in which his lower limbs were caught in a tractor. Clinical examination showed bilateral exposed knee dislocation. In addition there emerged right hip dislocation and composed acetabular fracture. There were no vascular arteries injuries, whilst there emerged an external popliteal sciatic nerve palsy to the left site. We performed the reduction manoeuvre revealing bilateral joint instability. For this reason the stabilization was made by external fixators. Due to right knee severe valgus instability, we performed medial collateral ligament reconstruction by intraosseous suture anchor using Leeds-Keio artificial implant after 1 month. Conclusions. In our case, due to the involvement of three major joints and nerve palsy, we had to perform the reduction manoeuvre, exploration and suture of peroneal nerve and stabilization by the external fixator. The opportuneness of ligament reconstruction may be evaluated at a second step in relation to functional expectancy and skin condition of the donor site.

“…9 In the third case, the reduction of the knee was not possible due to the incarceration of the medial meniscus within medial tibial plateau fracture. 10 revealed the right knee held in a slight flexion by 30 degrees and valgus deviation of 15 degrees. There was a diffuse tenderness around the knee with a transverse ecchymotic "puckering" of the skin over the anteromedial thigh; the medial femoral condyle was palpable just above the "pucker" (►Fig.…”

Knee dislocation is one of the few real orthopaedic emergencies. It is a serious but relative uncommon injury, representing less than 0.02% of all orthopaedic injuries. Especially posterolateral knee dislocation is much rarer condition that is often missed or misdiagnosed. The main feature of this very rare condition is to be irreducible by closed reduction due to the interposition of soft tissues inside the enlarged medial joint space, such as the medial capsule and retinaculum, vastusmedialis, and medial meniscus. The pathognomonic sign of a posterolateral knee dislocation is the anteromedial distal thigh transverse “pucker” or “dimple sign.” We report the case of an 87-year-old man who sustained an irreducible posterolateral fracture dislocation of the knee after being hit by car which has been treated with rotating hinge knee replacement with 1-year of follow-up.
