Medial Patellofemoral ligament(MPFL) is the main passive stabilizer of the patellofemoral joint. MPFL is injured in the 2/3 rds of the patients after patella luxation. In this study we present a novel aproach to the anatomical MPFL reconstruction and preliminary results of the technique. We operated 7 patients(4 female and female and 3 male) who applied to our clinic after a patella luxation episode. The mean age was 27,1 years(16-42). The mean follow up time was 23,5 months(24-35). We evaluated the patients clinically and radiologically for concommitant pathologies. 1 patient had patellar cartilage demage and patella alta, 1 patient had medial collateral ligament rupture, 1 patient had lateral collateral ligament and anterior cruciate ligament rupture and these pathologies were treated as well. The operation was done in the supine position on a radiolucent table and under the image intensifier control. The semitendinosus autograft was prepared. The femoral tunnel was drilled and double strand graft was introduced in the femoral tunnel and secured with ToggleLoc femoral fixation device(Biomet). The graft was advanced over the facia to the patellar side and passed through the 2 patellar tunnels and tied to each other. After exercising the knee the graft tension was rechecked at 30 degrees of knee flexion. Early postoperatively range of motion and quadriceps strenghtening exercises were carried out and patients were allowed to bear weight. All of the patients had full range of motion and free of pain. Postoperative x-ray and MRI examinations revealed the correction of patellar tilt and lateral shift of the patella in all patients. The only complication was a fissure of patella in 1 patient in the 6th week of rehabilitation due to anteriorly located patellar tunnel and heavy exercise. We immobilsed the patient in a brace and the patient returned to rehabilitation after 6 weeks when the fissure healed. All the patients returned to the previous functional level. Our anatomical MPFL technique uses ToggleLoc for the femoral side but implant free at the patellar side. The technique provided excellent preliminiary result in all of the patients. The technique allows graft retensioning again and again from both the femoral and the patellar side. The double bundle reconstruction seems to immitate the natural behaviour of the MPFL. However patellar tunnels carry a substantial risk of patella fracture and must be placed with great attention.

Patella Luxation

Aims and Objectives: The rupture of the acl is considered to be one of the most common knee injuries in sports traumatology. Many patients report that they felt the sensation of a luxated patella during their knee distorsion. In many cases patients patients with the suspicion of a traumatic patella luxation showed in the mri a complete rupture of the acl. Materials and Methods: We report about 10 patients consulting our department within the last year after a significant knee trauma. In the mri as well as during the arthroscopic evaluation they showed a complete rupture of the acl as well as the findings of a fresh, traumatic patella luxation. We evaluated and analysed the preoperative and intraoperative pictures (mri and arthrosopy). Results: All patients showed in the posttraumatic mri a complete rupture of the acl as well as an at least partial rupture of the mpfl and a rupture of the medial retinaculum. 4 patients showed a persistent subluxation of the patella, 8 patients showed also a rupture of the medial collateral ligament. During the operation we verified a significant instability of the patella in 8 patients so that a stabilization of the patella was performed (open medial stabilization or mpfl reconstruction) in the same operation the acl was reconstructed (semi-t). Eventhough the patients were treated with only one operation and the regaining of motion was prolonged compared with isolated acl-reconstruction, after 12 months postoperatively all patients had a satisfactory range of motion. Conclusion: The typical trauma mechanism for an acl rupture is a valgus position of the knee in combination with an external rotation of the tibia, which leads to an enlargement of the q-angle which is considered a predisposition for a patella luxation. If an acl rupture occurs, the patella can luxate within the same trauma. In the posttraumatic mri the rupture of the mpfl is often misinterpreted as a rupture of the medial collateral ligament, particularly if the patella is, as in most cases, in full reposition. Within an acl-rupture a luxation of the patella can occur simultaneously, leading to a significant instability which needs to be treated (medial stabilization or mpfl-reconstruction). Our data shows that a single stage treatment with acl-reconstruction and medial stabilization is technical practicable and mid-term investigation shows good clinical results without a higher risk of an arthrofibrosis.

SummarySeventeen dogs between three and 22 months of age were treated for avulsion fractures of the tibial tuberosity. The majority of dogs were greyhounds and bull terriers. Three cases had bilateral involvement. Eleven were treated surgically, four were treated conservatively and two were euthanatised. Lameness was resolved by the time of the last examination in 4/4 conservatively managed cases and 7/11 surgically treated cases. Postoperative complications were related to fracture fixation or growth abnormalities. Fixation complications included avulsion of the tuberosity from the implant, wire breakage, bending of a pin, mild patella luxation and a pin through the tibial plateau growth plate. Deformity of the proximal tibial plateau occurred in two dogs, and flattening of the tibial tuberosity with distal translocation developed in at least two other dogs.

PURPOSE: Comparative morphologic study of utilization of castor oil polymer in dogs joints, as an alternative technique to autogenous graft, in surgical correction of medial patella luxation. METHODS:Twelve adult dogs, of both sexes, were randomly allocated to two different groups of six animals each. Group I (biopolymer) consisted of the deepening of the right femoral troclea, with the implantation of the biopolymer prothesis, and compared to group II (control) which consisted of the conventional trocleoplastia technique with wedged cut of the left femoral troclea. The dogs were sacrified after 30 or 90 days and the anathomic peaces were analyzed macro and microscopically. Qui square and Wilcoxon tests were used for the statistic analyses of the results, considering probability of 5%. RESULTS: It was not observed bony integration on the castor oil polymer group. There was resorption of the graft along experimental period and absence of inflammatory cells in the studied periods. CONCLUSION: Castor oil polymer assisted cicatrisation process, was biocompatible without inflammation, and it can be used in joints as an alternative for bony filling.
