| Summary: | ABSTRACT: Background: The upper end of tibia is an important component of knee joint that plays a vital role in transmission of body weight from femur above to talus below. The knee joint is usually affected by arthritis (like post-traumatic, inflammatory), obesity, old age. Knee replacement surgery or knee arthroplasty is treatment of choice in severe osteoarthritis. In knee prosthesis, current challenges are centered on attempting to produce normal kinematics, reducing wear & tear and hence achieving greater longevity. Knowledge of morphometry of upper end of tibia provides reliable method of assessing knee deformity and estimating accurate size of prosthesis. Mismatch between morphometric data and selected prosthesis for surgery may cause severe complications like cruciate ligament rupture, soft tissue misbalancing, decreased movement of knee joint and even prosthesis loosening. As no study has been published on morphometry of upper end of tibia in Nepalese population, this study will provide key information in designing appropriate sizematched prosthesis in Nepali scenario. We also know that tibia is a complex anatomical structure; knowledge of the morphometric values is important in Forensic, Anatomic and Archeological cases in order to identify unknown bodies and statures. This study will serve as milestone for such type of investigations. Methods: A cross sectional study was conducted on 138 tibias of adult Nepalese population in Department of Clinical Anatomy, Maharajgunj Medical Campus. The sides, length, weight of tibia were noted. The antero-posterior and transverse diameters of total tibial condyle, medial and lateral condyles were measured and noted. Statistical analysis was done using IBM SPSS 17.0®. Results: A total of 138 tibias were included in the study. The mean length of tibia was 348.35±24.67 mm. The mean weight of tibia was 169.13±39.11 grams. The mean width of tibia was 75.84±7.43 mm. The mean length, weight and width of the right tibias were 350.36±22.30 mm, 172.52±39.76 grams and 77.21±7.50 mm and left tibias were 346.57±26.62 mm, 166.11±38.54 grams and 74.61±7.19 mm, respectively. The mean antero-posterior and transverse diameters of total tibial condyle were 46.75±5.18 mm and 69.62±6.29 mm respectively. The mean antero-posterior and transverse diameters of total tibial condyle of right tibias were 46.82±5.52 mm and 70.93±5.99 mm respectively. The mean antero-posterior and transverse diameters of total tibial condyle of left tibias were 46.68±4.89 mm and 68.45±6.36 mm respectively. The mean antero-posterior and transverse diameters of medial condyle were 44.17±5.75 mm and 30.86±4.66 mm respectively. The mean antero-posterior and transverse diameters of medial condyle of right tibias were 45.22±6.14 mm and 31.90±4.81 mm respectively. The mean antero-posterior and transverse diameters of medial condyle of left tibias were 43.23±5.24 mm and 29.93±4.34 mm respectively. The mean antero-posterior and transverse diameters of lateral condyle were 39.16±4.79 mm and 32.65±4.74 mm respectively. The mean antero-posterior and transverse diameters of lateral condyle of right tibias were 39.95±5.28 mm and 33.88±4.92 mm respectively. The mean antero-posterior and transverse diameters of medial condyle of left tibias were 38.47±4.20 mm and 31.55±4.32 mm respectively. The mean length between upper end of tibia and tibia tuberosity was 57.60±7.67 mm in right tibias whereas in left tibias was 54.82±7.52 mm and overall were 57.60±7.67 mm respectively. The most common type of tibial tuberosity was oblique type in both the sides. All bones have at least 1 nutrient foramen in the proximal third of tibia whereas three bones had more than 2 nutrient foramina. All the medial condyles were oval in shape except for three right tibias which had circular shaped medial condyle. 132 tibias had circular shaped lateral condyle whereas one left tibia and five right tibias were oval in shape. Conclusions: This study shows that there was significant difference between antero-posterior and transverse diameters of medial and lateral condyles as suggested by other studies. This study is important in enhancing the anatomical knowledge of upper end of tibia. |
