Analysis of the kinetic, kinematic and temporospatial parameters of gait, and their relationship to functional ambulation following total knee replacement using two different prosthetic designs
Analysis of the kinetic, kinematic and temporospatial parameters of gait, and their relationship to functional ambulation following total knee replacement using two different prosthetic designs
The aim of this research is to assess the efficacy of two different prosthetic designs used in total knee replacement operations in osteoarthritic patients. The study involved the analysis of the kinetic, kinematic and temporospatial parameters of gait, as well as the assessment of pain and the physiological cost of walking and functional activities.
54 osteoarthritic subjects were studied one week before total knee replacement (TKR) to compare them with 25 healthy control subjects in order to establish the baseline data. Fifteen patients received a posterior cruciate ligament (PCL) sacrificing prosthesis and thirty-nine patients had a PCL-retaining prosthesis.
The temporospatial gait parameters in both groups showed no significant differences between the two type of prosthesis during the study period. The range of knee motion during the stance and swing phase of gait was similar for both knee replacement groups, but increased progressively post-operatively in both groups, the range of motion being greatest at 9 months after operation. Knee moments in mid-stance for the patients with implants with PCL-retaining prosthesis were not statistically different from the PCL-sacrificing prosthesis until 9 months after surgery. The knee power at mid-stance in both groups revealed no significant differences at any stage. Abnormal muscle activity was noted during level walking in four lower limb muscles at 3 and 6 months after TKR, but phasic activity was noted at 9 months after TKR. All the gait parameters and electromyography improved 9 months after surgery compared with the preoperative value. The pain scores decreased significantly at 3, 6 and 9 months after surgery compared with the preoperative value.

Abstract
The aim of this research is to assess the efficacy of two different prosthetic designs used in total knee replacement operations in osteoarthritic patients. The study involved the analysis of the kinetic, kinematic and temporospatial parameters of gait, as well as the assessment of pain and the physiological cost of walking and functional activities.
54 osteoarthritic subjects were studied one week before total knee replacement (TKR) to compare them with 25 healthy control subjects in order to establish the baseline data. Fifteen patients received a posterior cruciate ligament (PCL) sacrificing prosthesis and thirty-nine patients had a PCL-retaining prosthesis.
The temporospatial gait parameters in both groups showed no significant differences between the two type of prosthesis during the study period. The range of knee motion during the stance and swing phase of gait was similar for both knee replacement groups, but increased progressively post-operatively in both groups, the range of motion being greatest at 9 months after operation. Knee moments in mid-stance for the patients with implants with PCL-retaining prosthesis were not statistically different from the PCL-sacrificing prosthesis until 9 months after surgery. The knee power at mid-stance in both groups revealed no significant differences at any stage. Abnormal muscle activity was noted during level walking in four lower limb muscles at 3 and 6 months after TKR, but phasic activity was noted at 9 months after TKR. All the gait parameters and electromyography improved 9 months after surgery compared with the preoperative value. The pain scores decreased significantly at 3, 6 and 9 months after surgery compared with the preoperative value.
