1/55. Distal disinsertion of the patellar ligament combined with avulsion fractures at the medial and lateral margins of the patella. A case report and an experimental study.

    A 12-year-old boy presented with a proximally retracted patella 5 months after an injury to the left knee. The clinical and radiographic features and the findings at operation led to the conclusion that the original lesion had been a distal disinsertion of the patellar ligament combined with avulsion fractures at the medial and lateral margins of the patella, produced by the medial and lateral longitudinal patellar retinacula. Loading experiments on amputation and cadaver specimens showed that these retinacula, apart from being tendons for the vastus medialis and the vastus lateralis, respectively, constitute a direct fibrous connection of considerable strength between the patella and the tibia and thus are capable of producing avulsion fractures.

2/55. Patella fracture and proximal patellar tendon rupture following arthroscopic anterior cruciate ligament reconstruction.

    The central one-third bone-patella tendon-bone graft is a popular choice for arthroscopic anterior cruciate ligament reconstruction. Complications following graft harvesting are unusual, but several reports have been published. We report an unusual case involving a simultaneous patella fracture and patellar tendon rupture that occurred 6 weeks postoperatively.

3/55. An unusual complication affecting an unresurfaced patella after total knee arthroplasty.

    The unusual clinical presentation of a complication involving an unresurfaced patella after a total knee replacement is reported. The management and possible pathology are discussed.

4/55. Arthroscopic reduction and fixation of osteochondral fracture of the patellar ridge.

    A method of arthroscopic reduction and anterograde fixation of osteochondral fracture of the patella ridge is described. This type of fracture was previously treated through arthrotomy. An arthroscopic approach is possible using manipulation of the patella in a loosened medial retinaculum. This method was used in a 14-year-old patient with an osteochondral fracture following the dislocation of the patella.

5/55. Patellar fractures associated with medial-third bone-patellar tendon-bone autograft ACL reconstruction.

    Patella fractures following anterior cruciate ligament (ACL) reconstruction are a recognized but rarely reported complication. To our knowledge, 24 reports of patella fractures after ACL reconstruction using the central-third patella-tendon autograft have been reported in the literature. Patellar fractures associated with the use of the medial-third bone-patellar tendon-bone autograft have not been reported. This article describes four cases of patellar fractures in 478 ACL reconstructions between 1992 and 1999, using the medial third of the patellar tendon graft. All of them were transverse fractures of the patella but only one was displaced. All patients suffered local injury to the donor knee between 2 and 4 months postoperatively. No significant differences in the final outcome were noticed between the cases complicated with patellar fracture and those with uncomplicated ACL reconstructions.

6/55. pseudallescheria boydii knee arthritis in a young immunocompetent adult two years after a compound patellar fracture.

    pseudallescheria boydii arthritis of the knee developed in a 32-year-old immunocompetent man 2 years after a compound patellar fracture contaminated with soil. No other potential portal of entry was identified, suggesting that the fungus remained latent for 2 years. pseudallescheria arthritis often occurs after a prolonged latency period, causing minimal symptoms that contrast with the frequently severe radiological changes. Although this organism often shows limited sensitivity to most antifungal agents, our patient achieved a full recovery after surgical synovectomy and 6 months of itraconazole therapy (400 mg/ d). This case illustrates the importance of testing for fungi in patients with torpid arthritis, particularly when mild clinical symptoms contrast with severe bone and joint destruction.

7/55. Late reconstruction of the patellar tendon.

    A case of late reconstruction of the patellar tendon is reported. Besides partial loss of the tendon, the patient also had loss of the distal third of the patella. A rolled strip of fascia lata was used to reconstruct the tendon with tunnels through the patella. At the tenth month of follow-up, the result was deemed successful.

8/55. Arthroscopic-assisted percutaneous screw fixation of select patellar fractures.

    PURPOSE: To describe a technique of arthroscopic-assisted reduction and percutaneous cannulated screw fixation for displaced patellar fractures and to present the results of 5 cases. Type of Study: Case series. methods: Five patients (3 male, 2 female) with displaced patellar fractures treated with an arthroscopic-assisted reduction and percutaneous cannulated screw fixation were prospectively analyzed. The mean age was 53 years (range, 27 to 74 years). All fractures were fixed with at least 2 4-mm cannulated screws under arthroscopic visualization. Cerclage wiring through the cannulated screws was necessary in 2 patients with osteopenic bone. Controlled passive range of motion exercises were started on the first postoperative day. Full weight bearing with an immobilizer-type brace was allowed as tolerated. The mean follow-up was 28 months (range, 24 to 35 months). The patients were evaluated with Lysholm II scores, clinical examination, knee range of motion, thigh circumference measurements, and radiographs. RESULTS: All fractures healed uneventfully. The mean Lysholm II score was 84.8 (range, 75-96). All but 1 patient regained full knee range of motion. A mean quadriceps atrophy of 0.8 cm compared with the contralateral side was seen in unilateral cases. There was no implant failure or infection. CONCLUSIONS: Arthroscopic-assisted reduction and percutaneous cannulated screw fixation is appropriate for displaced transverse patellar fractures without major separation and comminution. Longitudinal or oblique fractures, even if there are more than 2 major fragments, are amenable to arthroscopic techniques, providing the fragments are large enough to be fixed with screws. This technique is minimally invasive and does not disturb the vascular supply of patella. It allows clear visualization of the reduction and stability of the fracture, and facilitates early postoperative range of motion exercises. This method is not suitable for highly comminuted fractures or transverse fractures with major separation that are accompanied by rupture of the extensor mechanism.

9/55. Internal fixation of a patella fracture using an absorbable suture.

    This case report describes the use of an absorbable suture for the fixation of a patella fracture in a child. In this case the fracture was held satisfactorily by the suture until union. This technique means that there is no need for a second operation to remove the fixation material.
