    OBJECTIVE:To study the anatomy of the oblique popliteal ligament, as regards its dimensions, expansion and anatomical relationships.METHODS:Eleven cadaver knees were dissected in order to study the anatomy and take mea-surements of anatomical structures and relationships of the oblique popliteal ligament. The dissection was for posterior access to the proper exposure of the oblique popliteal ligament, the semimembranosus muscle and its expansions. For measurement of dimensions, 40 × 12 needles were used for marking the specific points and a caliper. The angles were calculated using the software ImagePro Plus(r) .RESULTS:The distance from the origin of the oblique popliteal ligament to the tibial plateau was 7.4 mm, the thickness at its origin was 7.3 mm, length was 33.6 mm and the tibial plateau angle 34.8°. The length of the expansion of the proximal oblique popliteal ligament was 39.2 mm, thickness 7.8 mm and angle of the oblique popliteal ligament with its expansion 32.2°.CONCLUSION:The oblique popliteal ligament is thick, rises in the semimembranosus and protrudes proximally forming an acute angle with the joint interline, crossing the popliteal fossa. In some cases it has a proximal expansion.OBJETIVO:Estudar a anatomia do ligamento poplĂ­teo oblĂ­quo no que se refere Ă s suas dimensĂ”es, expansĂ”es e relaçÔes anatĂŽmicas.MÉTODOS:Onze joelhos de cadĂĄveres foram dissecados com o intuito de se estudar a anatomia e fazer mediçÔes das estruturas e das relaçÔes anatĂŽmicas do ligamento poplĂ­teo oblĂ­quo. A dissecção foi por acesso posterior atĂ© a exposição adequada do ligamento poplĂ­teo oblĂ­quo, do mĂșsculo semimembranoso e de suas expansĂ”es. Para aferição das medidas, foram usados agulhas 40x12 na marcação dos pontos especĂ­ficos e um paquĂ­metro. Os Ăąngulos foram calculados com o auxĂ­lio do software ImagePro Plus(r).RESULTADOS:A distĂąncia da origem do ligamento poplĂ­teo oblĂ­quo ao platĂŽ tibial foi de 7,4 mm, a espessura na sua origem foi de 7,3 mm, o comprimento foi de 33,6 mm e o Ăąngulo com o platĂŽ tibial foi de 34,8°. O comprimento da expansĂŁo proximal do ligamento poplĂ­teo oblĂ­quo foi de 39,2 mm, a espessura foi de 7,8 mm e o Ăąngulo do ligamento poplĂ­teo oblĂ­quo com sua expansĂŁo foi de 32,2°.CONCLUSÃO:O ligamento poplĂ­teo oblĂ­quo Ă© espesso, nasce no mĂșsculo semimembranoso, projeta-se proximalmente, forma um Ăąngulo agudo com a interlinha articular e cruza a fossa poplĂ­tea. Em alguns casos apresenta uma expansĂŁo proximal.Universidade Federal do ParanaUniversidade Federal de SĂŁo Paulo (UNIFESP)Universidade Federal de SĂŁo Paulo (UNIFESP) Escola Paulista de MedicinaPontificia Universidade Catolica do ParanaUNIFESP, EPMSciEL

    OBJECTIVE: To study the anatomy of the hamstring tendons insertion and anatomical rela-tionships. METHODS: Ten cadaver knees with medial and anterior intact structures were selected. The dissection was performed from anteromedial access to exposure of the insertion of the flexor tendons (FT), tibial plateau (TP) and tibial tuberosity (TT). A needle of 40 × 12 and a caliper were used to measure the distance of the tibial plateau of the knee flexor tendons insertion at 15 mm from the medial border of the patellar tendon and tibial tuberosity to the insertion of the flexor tendons of the knee. The angle between tibial plateau and the insertion of the flexor tendons of the knee (A-TP-FT) was calculated using Image Pro Plus software. RESULTS: The mean distance TP-FT was 41 ± 4.6 mm. The distance between the TT-FT was 6.88 ± 1 mm. The (A-TP-FT) was 20.3 ± 4.9°. CONCLUSION: In the anterior tibial flexor tendons are about 40 mm from the plateau with an average of 20°
