[Ultrasound imaging of congenital knee joint dislocation. Value in diagnosis and therapy].

Congenital dislocation of the knee is a uncommon malformation. Frequently there is an association with other congenital deformities including congenital dislocation of the hip. The classification of Leveuf and Pais into three separate groups (Type A, Type B, Type C) is now widely accepted. Between October 1989 and April 1995 we evaluated ten children (five girls and five boys) with twelve dislocated knees. Clinical, radiographic and different ultrasonography examinations were carried out on both knees. The sonographic classification showed Type A in 3, Type B in 5 and Type C in 4 cases. The sonographic examination revealed the essential anatomic structures and their pathomorphology. The anterior and the posterior cruciate ligament could be demonstrated in the majority of the cases. Three dislocated knees showed an obliteration of the recessus suprapatellaris and fibrotic changes in the m. quadriceps. These cases required operative treatment. With conservative treatment we achieved a satisfactory result in eight children with nine disease knees. There was a good functional result with an average flexion of 106 degrees. Early conservative treatment recommend as the therapy of choice. Ultrasonography imaging offers the possibility of reliable differentiation into one of the three groups of the classification of Leveuf and Pais. Radiographic documentation during the therapy has become the exception. Ultrasonography imaging helped substantially in the decision making and the timing of operative treatment.

Fracture--dislocation of the knee.

Fractures of the proximal tibia involving the articular surfaces vary greatly in type, severity, and prognosis, and a considerable percentage have significant associated ligamentous injuries. This report classifies and analyzes 132 particular fractures separated from over 1,000 patients with fractures of the proximal tibia. The remaining cases were considered to have tibial plateau fractures. Eighty-six fractures required operative treatment, and it was possible to divide them into five distinct types. The characteristic of these five types is marked joint instability with a high incidence of serious soft-tissue and/or neurovascular injury. Knee dislocation is a discrete entity. Plateau fracture is a discrete entity that requires definition (and which in large measure has little or no implication of significant soft-tissue injury). Fracture--dislocation of the knee is a much more serious injury than plateau fracture. For successful treatment of this injury, a radically different understanding of fractures of the proximal tibial condyles is needed.

[Popliteal trauma due to posterior dislocation of the knee].

Popliteal artery injuries have an incidence ranging between 5% and 19% of all traumatic arteria lesions. A high index of amputation, when associated with lesions of the infrapopliteal branches, and a 4-5% overall mortality are recorded in these conditions. Three patients with popliteal artery injury due to posterior knee dislocation were operated upon in our department during the last 12 months. In one case, the physical examination revealed a warm limb, with peripheral pulse; angiography showed a pseudoaneurysm of the popliteal artery with intimal dissection and partial thrombosis. In the last two cases an acute ischemia of the limb was present; in one case the angiographic study showed a complete transection of the artery, while in the second case an obstruction of popliteal artery. In all cases the dislocation was corrected and a the reconstruction carried out by inverted autologus saphenous vein with termino-terminal anastomosis. In all cases a good patency of the popliteal reconstruction was achieved with limb salvage. Prognosis of popliteal injuries is related to an early diagnosis and they should be suspected even in absence of overt signs of acute ischemia. Surgical timing cannot be the same in all cases. The need for a preliminary orthopedic phase with its modality must be established case by case, relating to the severity of ischemia, to the time elapsed between trauma and surgery, to the peculiarities of skeleton and joints lesions.

Vascular injuries associated with dislocation of the knee.

Two hundred and forty-five knee dislocations were analyzed including forty-one new cases. The high incidence of injuries to the popliteal artery that accompanies this lesion (32 per cent) was confirmed, and it was re-emphasized that vascular repair must be completed within six or at the most eight hours from the time of injury to avoid amputation. Of the patients not treated within that time period, 86 per cent had an amputation and two-thirds of the remaining 14 per cent had ischemic changes.

Congenital dislocation of the knee.

Twenty-three congenital knee dislocations in 17 patients were reviewed after an average follow-up of 11 years. There was a 30% incidence of breech delivery along with a 41% incidence of clubfoot. Treatment in serial casts was successful in 10 knees; 13 required operations. Prognosis was most favorable in unilateral cases and when surgery was performed before 2 years of age. Quadriceps lengthening during knee surgery facilitated the subsequent reduction of ipsilateral dislocated hip.

Dislocation of the knee with lateral dislocation of the patella. A report of four cases.

In a group of 25 patients with traumatic dislocation of the knee, four, all of whom had similar ligament and medial soft-tissue injuries, also had associated lateral patellar dislocation. In all four reconstruction was delayed because of their other serious injuries. Having encountered the combination of knee dislocation and lateral patellar dislocation in 16% of our patients, we believe that it may be less rare than is commonly believed. We think that it is important to maintain a high index of suspicion of possible patellar dislocation when medial structures have been severely damaged. Early recognition and immobilisation in extension can prevent fixed lateral dislocation of the patella.

Dislocation of the knee.

The complications of knee dislocations may be disastrous and must be anticipated. In most series, a 25 to 30 per cent incidence of arterial damage is reported. If the artery is not repaired, the incidence of amputation can be up to 72.5 per cent. The popliteal artery should be evaluated and vascular repair performed as needed. This must be completed within a 6 to 8-hour period after injury for optimal results. Peroneal nerve injuries are common, and permanent neurologic damage may result. The neurovascular injury should be well documented both at the time of injury and in the preinjury state. After all problems affecting limb survival are solved, open repair of all ligamentous injuries is recommended to provide ligamentous stability and congruity of the joint. Prior to performing the procedure, a surgeon must have a thorough knowledge of the anatomy of the knee. Rehabilitation techniques and early postoperative motion are important for guiding the injured patient through the immediate and late postoperative period.

[Treatment of closed dislocations of the knee joint].

Nineteen knee dislocations in 18 patients (one bilateral) occurred over a period of twelve years. The age range was 17 to 70 years with an average age of 33 years. There was no injury of the popliteal artery and five peroneal nerve injuries in the group. One compartment syndrome occurred after reduction. The follow-up study including examination showed good and satisfactory results for early surgical repair. After delayed surgical repair there were more signs of instability, pain and restrictive range of flexion movement. Early operative repair followed by cast bracing for six weeks and an intensive mobilisation therapy after cast bracing are the method of choice. An immobilisation period of three to four weeks is possible.

Results following treatment of traumatic dislocations of the knee joint.

In a retrospective study, 31 patients were identified over a period of 25 years as having sustained traumatic knee dislocations without associated fractures. Three patients had early amputation secondary to vascular complications. Ten popliteal artery disruptions and five peroneal nerve palsies were diagnosed. At the time of follow-up evaluation (average, 40 months), 16 patients were examined. Operatively treated patients (n = 6) tended to have better motion (129 degrees) than nonoperatively treated patients (108 degrees). Varus instability was seen in only two patients treated nonoperatively. All patients except one experienced persistent functional limitations. Roentgenographic follow-up examination showed similar degenerative changes in both groups.

[Dislocation of the knee joint].

Dislocations are the rarest but the most severe injuries of the knee joint. Six patients with traumatic knee joint dislocation were treated at the Clinic for Traumatology and Orthopedics of the Military Medical Academy in the period January 1989-November 1998. Popliteal artery was injured in 3 patients. The injuries required reconstruction and the treatment in 1 patient ended with upper leg amputation. In one case the diagnosis was irreducible lateral dislocation. Surgical reparation--reconstruction of ligamentary apparatus was performed in 4 patients. Concerning the knee joint stability satisfactory results were achieved. Knee joint dislocations are very severe injuries requiring thorough diagnosis of the possible injury of neurovascular bundle and surgical treatment.

[Case histories of therapy of traumatic knee joint dislocation].

The records of eight patients with traumatic knee dislocation and operative treatment in 1981-1991 were reviewed. In this retrospective study the average follow-up was 6 years and indicated good results concerning stability and functional use of the knee. The vascular complications, especially the ischemic syndrome are associated with an emergency situation that requires immediate reduction.

Blunt popliteal artery trauma: a challenging injury.

Blunt popliteal artery trauma is a challenging injury, particularly when associated with major soft tissue damage. We reviewed our experience with this injury to determine 1) the incidence of vascular injury associated with fractures and/or dislocations about the knee, 2) the incidence of limb loss, and 3) factors associated with amputation. We treated 37 patients with 38 blunt popliteal artery injuries and either fractures about the knee or posterior knee dislocations. Patients who underwent primary amputations were excluded. The incidence of popliteal artery injuries with fractures about the knee was 3 per cent, whereas 16 per cent of patients with posterior knee dislocations had vascular injuries (P < 0.05). Amputations were required in 14 of the 38 injured limbs (36%). None of these patients had a pulse or Doppler signal on admission, and 13 had major soft tissue injury. No patient with a pulse or Doppler signal lost a limb (P < 0.05). Limb loss was primarily related to limited venous outflow and/or severe infection in damaged tissue. Failure of the arterial repair rarely led to amputation, particularly in recent years. Two patients with angiographically proven arterial injuries were treated nonoperatively without complications. The incidence of vascular injuries associated with fractures about the knee is low, but somewhat higher with posterior knee dislocations. The overall 9 per cent rate of positive angiograms suggests that a selective approach may be indicated. The amputation rate remains high, but it has improved with an integrated, multidisciplinary team approach. In patients without a pulse or Doppler signal and with severe soft tissue injuries, primary amputation may be appropriate.
