1/157. Intercondylar notch fibrous nodule after total knee replacement.

    Intra-articular fibrous bands and soft-tissue impingement under the patella after total knee replacement are a well known complications that can be diagnosed and treated arthroscopically. Arthroscopic treatment of soft-tissue impingement between femoral and tibial components in a total knee arthroplasty has been recently reported. The purpose of this article is to report one more case of this pathology of a more fibrotic type resembling a nodule in the intercondylar notch that prevents total extension and to discuss the possible origin and clinical significance. Finally, we propose a classification of the fibrotic reactions after total knee arthroplasty: (A)Multiples or complex bundles reactions; and (B)singles or isolates nodular forms: fibrous nodule in the femoropatelar area (clunk syndrome), and fibrous nodule in the intercondylar notch.

2/157. A technique for reconstruction of the medial patellofemoral ligament.

    Additional medial patellofemoral ligament reconstruction was performed successfully on six consecutive patients with recurrent dislocation of the patella because of residual patellar instability after medial transfer of the tibial tubercle. A technique for medial patellofemoral ligament reconstruction is described, and complications and postoperative management are discussed. The reconstruction was performed using a double strand hamstring tendon graft in five patients and iliotibial allograft in one. Good stabilization of the patella was achieved in all six patients, resulting in improved confidence in higher levels of activity. The satisfactory outcome of additional medial patellofemoral ligament reconstruction suggests the possibility that the procedure may be part of the optional procedure in proximal realignment for recurrent dislocation of the patella.

3/157. Neurological complications of anterior spinal surgery for kyphosis with normal somatosensory evoked potentials (SEPs).

    We report a case of neurological complications of anterior release for correction of kyphosis. After the operation, the patient had pyramidal weakness and decreased pain sensation below T5, whereas light touch, proprioception and vibration sensation were intact. Clinical and neurophysiological findings in this patient suggested a partial lesion of the spinal cord probably due to ischaemia in the territory of the anterior spinal artery. Intraoperative and postoperative tibial nerve SEPs remained normal, which stresses the need for recording from the motor pathways.

4/157. Tibial and pretibial cyst formation after anterior cruciate ligament reconstruction with bioabsorbable interference screw fixation.

    We report a case of an osteolytic tibial enlargement in association with a pretibial cyst formation 8 months after successful anterior cruciate ligament reconstruction with autologous bone-patellar tendon-bone graft and tibial graft fixation with a bioabsorbable interference screw. No joint inflammatory reaction or graft insufficiency was detected. The patient underwent cyst excision and curettage of the tibial tunnel with full recovery and return to preinjury level of activity 2 months after the revision surgery. To our knowledge, the reported complication is the first obvious adverse reaction to a poly-D,L-lactide interference screw in anterior cruciate ligament surgery.

5/157. Early experience with total knee replacement.

    This paper presents a review of two years' experience with the geometric total knee replacement. The results of 23 arthroplasties in 22 patients are discussed. Relief of pain was consistent and dramatic, movement was increased postoperatively in only three patients, but imporvement in overall function occurred in 20 of the 22 patients. There was one failure requiring arthrodesis. In this patient, six months after surgery the medial tibial condyle collapsed and the polyethylene tibial component fractured. This complication has not been reported before. Early results are encouraging. Total knee joint replacement is a useful procedure in advanced arthritis when arthrodesis is the only alternative.

6/157. Pseudoaneurysm formation in surgically treated Behcet's syndrome--a case report.

    Behcet's syndrome is a multisystem disorder with unknown etiology. Clinically it is mostly seen as a systemic vasculitis; almost 30% of the patients have vascular involvements, and most of these are venous thrombosis and arterial aneurysms. Obstructions of the femoral and tibial arteries have also been reported in the literature. The authors present here a patient with Behcet's syndrome who had pseudoaneurysms on both femoral arteries after aortobifemoral bypass surgery.

7/157. Severe osteopenia with recurrent fractures after bone marrow transplant for wiskott-aldrich syndrome: a case report.

    wiskott-aldrich syndrome (WAS) is a rare inherited disorder characterised by thrombocytopenia, eczema, and immunodeficiency. bone marrow transplantation (BMT) is a well-established modality of treatment now routinely used and often curative. We report the case of a boy who developed osteopenia and sustained multiple long-bone fractures over a 5-year period after bone marrow transplant for WAS. The femora and tibiae of both lower limbs were involved with a clinical presentation similar to osteogenesis imperfecta. After commencing calcitriol treatment at the age of 8 years, the patient has not sustained any further fractures. He is now 11 years old. Although short-term changes in bone metabolism after BMT have been documented, the occurrence of repeated fractures associated with osteopenia has not been previously reported.

8/157. Recurrent posterior dislocation following primary posterior-stabilized total knee arthroplasty.

    In our series of 136 patients with primary total knee arthroplasty using posterior-stabilized prosthesis, a female patient with parkinson disease developed posterior dislocation of the knee 9 months after surgery. Eventually, the dislocation became recurrent, occurring several times a day. The patient made the reposition always by herself. Two months after the first dislocation, we performed the revision of the polyethylene tibial insert and found wearing of the tibial insert's cam as an hitherto unreported cause of the mechanical instability of the total knee prosthesis.

9/157. Treatment of a case of congenital pseudarthrosis of the tibia-fibular osteosynthesis.

    We report the results of a case of congenital pseudarthrosis of the tibia treated by tibiofibular synthesis. A 1-year old girl was first treated by intramedullary fixation followed by an intertibiofibular bone graft. This method failed. She then underwent a new operation that was associated two simultaneous approaches, correction of the axis, tibiofibular synthesis and a new intertibiofibular bone graft. Union was achieved four months later. The child has now been followed up for 20 years. During this time, she has led a normal life as we have observed a "tibialisation" of the fibula. Intramedullary fixation has a success rate of 75% but requires repetitive insertion of intramedullary or telescopic rods. Transplantar intramedullary rods are responsible for significant ankle stiffness. Tibiofibular synthesis associated with an intertibiofibular bone graft after correction of the axis is the equivalent of vascularised graft of the fibula but with neither the difficulties of microsurgery nor valgus deformities of the ankle.

10/157. Fascial feeder and perforator-based V-Y advancement flaps in the reconstruction of lower limb defects.

    The principle of the V-Y advancement flap has been used since its first description by Blasius (1848) for reconstruction of smaller defects. We wish to describe V-Y advancement flaps, the design of which includes distinct perforator or fascial feeder vessels, which may originate from periosteum, muscle, cutaneous nerve or from large tendon sheaths. These flaps are planned in an oblique manner when there is a defect over the anterior, antero-lateral or antero-medial aspect, and in a vertical manner when there is a defect over the posterior aspect of the leg. The main advantage of this design is the ability to close the secondary defect primarily, allowing adequate cover of the defect, particularly in the pre-tibial region, without the unsightly divot left by a split skin graft in this area. When the flap includes branches of the long saphenous nerve on the medial aspect, superficial peroneal nerve laterally or sural nerve posteriorly it results in a sensate flap, giving protection in this vulnerable area, which has previously not been possible. We describe 40 cases where perforator-based V-Y advancement flaps have been used to cover large defects of the lower leg following excision of malignant skin lesions and in selected trauma cases that do not involve degloving injuries. This technique allows adequate soft tissue cover in the pre-tibial area and around the ankle with excellent aesthetic results. The planning, operative technique and the results with case presentations have been described.
