Abstract:
The ability to kneel is an important function of the knee joint required for many of the daily activities including religious practices, professions and recreation. Inability to kneel after knee replacement is a frequent cause for dissatisfaction. This work attempts to investigate whether kneeling ability varies after different knee replacement procedures. It also attempts to identify factors that may affect kneeling ability through clinical, anatomical, histo-pathological and biomechanical studies. Patients' perception of their post-operative ability to kneel was generally poor. but showed improvement when compared with their pre-operative ability. Patients with uni-compartmental replacement showed better kneeling ability than those with either total or patello-femoral replacement. Patients' ability to descend stairs was much better than their ability to kneel when the two functions were compared. Patients with fixed bearing implants had a better perceived kneeling ability than those with mobile bearing. Patients' observed kneeling was far better than their perception. The range of motion proved to be an important factor. Normal individuals from a similar age group had better kneeling ability when compared with knee replacement patients. Patients' kneeling ability was also affected by skin sensory alteration after knee replacement emphasising the importance of placement of surgical incisions to avoid injury to sensory nerves. Weight transmitted through the knee decreased with increased f1exion. Contact pressures on a force plate dropped Significantly when ROM was at maximum. The ability to kneel after knee replacement is important for many people. Although forces transmitted through the knee in extreme flexion are reduced, the kinematics of the knee in this position needs to be characterised.
