Research summary
The number of Total Knee Replacements (TKR) being performed in the UK is increasing year on year, and has more than doubled in the last 10 years, 48,787 in 2004 to 101,115 in 2014 (National Joint Registry 2015). The number of young patients is also ever increasing; Kurtz et al. (2009) suggested that the number of TKR in young people will increase significantly over the next 15 years. Current TKR are not adequate in function to allow young patients to perform activities that their healthy counterparts can.
Gait cycle analysis has repeatedly been assessed in many TKR’s this has demonstrated that there are a number of significant differences between TKR and control patients (McClelland et al. 2011; Sosdian et al. 2014). Studies comparing pre and post-op also report significant improvements in outcome measures (Hatfield et al. 2011). The results suggest that despite the significant improvements post-TKR, there is still room for improvement in the results of TKR, especially within the younger populations.
Due to this shift in age of TKR patients a new generation implant the Physica KR (Limacorporate spa) has been designed to replicate normal knee biomechanics. Limacorporate spa and Bournemouth University have match funded this PhD project and will use patients from the Royal Bournemouth Hospital; all participants are also part of the Physica KR follow-up clinical trial.
The Physica KR claims to replicate normal knee biomechanics. To assess this Physica KR; walking, running, pivot turn and kneeling kinematics and kinetics will be studied. Running and turning are activities not previously assessed in the literature for TKR patients, but are likely to be performed by active TKR patients; if they are to get back to pre-TKR activity. This would therefore suggest that the new generation knee can perform activities that have yet to be investigated in TKR patients.
