- Anatomical study on the anterolateral ligament of the knee(2013) HELITO, Camilo Partezani; MIYAHARA, Helder de Souza; BONADIO, Marcelo Batista; TIRICO, Luis Eduardo Passareli; GOBBI, Riccardo Gomes; DEMANGE, Marco Kawamura; ANGELINI, Fabio Janson; PECORA, Jose Ricardo; CAMANHO, Gilberto LuisOBJECTIVE: Describe the knee anterolateral ligament (ALL) and establish its anatomical marks of origin and insertion. METHODS: Dissection of the anterolateral aspect of the knee was performed in six cadavers. After isolation of the ALL, its lenght, width and thickness were measured as its places of origin and insertion. The ALL origin was documented in relation to the lateral collateral ligament (LCL) origin and the insertion was documented in relation to the Gerdy tubercle, fibullar head and lateral meniscus. After the first two dissections, the ligament was removed and sent to histologycal analysis. RESULTS: The ALL was clearly identified in all knees. Its origin in the lateral epycondile was on average 0.5 mm distal and 2.5 mm anterior to the LCL. In the tibia, two insertions were observed, one in the lateral meniscus and another in the proximal tibia, about 4.5 mm distal to the articular cartilage, between the Gerdy tubercle and the fibullar head. The average measures obtained were: 35.1 mm lenght, 6.8 mm width and 2.6 mm thickness. In the ligament histological analysis, dense connective tissue was observed. CONCLUSION: The ALL is a constant structure in the knee anterolateral region. Its origin is anterior and distal to the LCL origin. In the tibia, it has two insertions, one in the lateral meniscus and another in the proximal tibia between the Gerdy tubercle and the fibullar head.
- Results of revision total knee arthroplasty using press-fit cementless stem(2013) IAMAGUCHI, Maurcio Masasi; CASTRO FILHO, Fernando Bley Vicente de; GOBBI, Riccardo Gomes; TIRICO, Luis Eduardo Passarelli; PECORA, Jose Ricardo; CAMANHO, Gilberto LuisObjective: To show our experience with press-fit cementless stem and metaphyseal fixation with cement in a selected series of patients who underwent revision total knee arthroplasty. Methods: Thirty-four patients (35 knees) underwent revision total knee arthroplasty using the press-fit technique. Minimum follow-up was one year (mean 2.2 years) with a maximum length of three years. Results: Of 34 patients, 20 were women and 14 were men. There was one death due to causes not related to arthroplasty and one patient dropout. There were no cases in which further review was necessary. Patients who underwent revision had clinical and functional improvement demonstrated by the results of the KSS, results of the SF-36 quality of life questionnaire, through gains in range of motion and improved limb alignment. Conclusion: There was postoperative clinical and functional improvement in comparison to the preoperative status in revision total knee arthroplasty with press-fit cementless stem. Level of Evidence IV, Case Series.
