Student Number : 9707737A - MSc Dissertation - School of Anatomical Sciences - Faculty of Health Sciences / This study design was built around investigating the correlation between facet joint degeneration and ipsilateral annular fissuring or degeneration of the intervertebral disc. It was necessary to establish firstly whether this combination existed and if so, how prevalent it was. The study design incorporates macroscopic and microscopic examination of the intervertebral disc as well as the injection of a radio opaque dye into the nucleus in order to observe dye migration and identify fissuring in the anulus fibrosus of the intervertebral disc. The articulating facet joints were also examined macroscopically and microscopically. A correlation of findings reported in a tabular form should then reveal the existence of the foregoing proposition. The dissertation design did not incorporate examination of range of motion, but the effect of motion was reported in the literature review.

Total knee arthroplasty is a widely used and relatively successful procedure, designed to relieve pain and restore function to patients suffering from osteoarthritis. However, satisfaction following the procedure is low. One of the primary sources of pain and a cause of functional limitations following knee arthroplasty is the patellofemoral joint. Reasons for pain in the patellofemoral joint are not well understood but adverse patellofemoral biomechanics are thought to contribute. Many in vitro methods exist for the investigation of patellofemoral joint biomechanics but there is no consistent standard protocol. It is therefore difficult to draw any general conclusions regarding the effect of specific design or alignment factors on the biomechanics of the patellofemoral joint. The present study aimed to improve current understanding of factors contributing to patellofemoral complications. A knee simulator, which was based on the Oxford Knee Rig and included synthetic models for a number of soft tissue and bony structures, was developed. The simulator was demonstrated to provide a simplified but physiologically relevant model of the human knee, which allowed effective assessment of patellofemoral joint biomechanics under physiological loads. The system eliminated the need for cadaveric tissue and therefore demonstrated reduced variability, enabling the efficient assessment of a number of potentially influencing factors. A number of investigations were carried out using the simulator to assess the effect of patella component design and position, and femoral component alignment on patellofemoral biomechanics using the Scorpio NRG system. The results of these studies indicate the benefit of medialisation of the apex of the patella component and warn against excessive femoral component sagittal plane malalignment. However, in general they indicated the relatively forgiving nature of the Scorpio system to malalignment and highlighted that irrespective of alignment and patella component design, pressures in excess of material limits are frequently achieved in deep flexion.

The lack of hamstring muscle group flexibility has previously been associated with a higher incidence of hamstring strains among athletes. Several stretching methods have been shown to increase hip joint range of motion (ROM); however, identification of an optimal stretching method has proven difficult. The purpose of this study was to find an optimal method of stretching to improve hip flexion range of motion. Forty-three female college students, ranging in age from 18 to 29 yrs., volunteered to participate in this study. The subjects were randomly assigned to one of three stretching groups: static, contract relax, contract relax agonist contract. The subjects' maximal passive and active hip flexion ROM values were measured using an inclinometer. The subjects were stretched by the same partners at a rate of six days a week for a total of 20 treatments over a 23 day period. The selected stretching techniques produced significant pretest to posttest increases (p<0.02) in both passive and active hip flexion ROM. None of the stretching techniques improved passive or active hip flexion ROM significantly more the contract relax agonist contract technique producing an average increase of 17.6 �� 14.1 deg, and the contract relax technique resulting in an average increase of 12.0 �� 10.8 deg. A significant stretching technique x pretestiposttest interaction was found for the passive ROM values (p<.02). Scheffe' post hoc analysis of simple interaction effects revealed that the static stretching technique improved posttest passive hip flexion ROM significantly more than the PNF contract relax stretching method (p<.05). The results suggest that all three stretching techniques selected for this study are effective in increasing hip flexion range of motion. Static stretching of the hamstring produced the greatest increases in both passive and active hip flexion ROM, but no optimal technique was identified. / Graduation date: 1996
