Study information
Scientific title
Investigator Initiated Depuy Replacement knee In-Vivo Evaluation Study: a post-operative comparator study characterising the in-vivo functional capacities of patients following total knee arthroplasty (TKA) after randomisation to one of two different implant types
Acronym
DRIVE
Study hypothesis
To compare the in-vivo function of the PFC sigma cruciate retaining (CR) implant with the PFC CR 150 at 3, 6 and 12 months post-operatively.

Condition
Osteoarthritis
Intervention
A total of 40 patients will be recruited to the study. These patients will undergo a range of baseline evaluations as appropriate to their presenting condition. These would include:
1. A routine musculoskeletal clinical examination (including assessment of presenting symptoms and clinical musculoskeletal functional tests)
2. Completion of relevant patient reported outcome instruments (36-item short form health survey [SF-36], Oxford knee score, Knee Injury and Osteoarthritis Outcome Score [KOOS], Knee Society Clinical Rating System [KSS])
3. Knee joint kinematics and kinetics measured using Vicon T series, Oxford Metrics Oxford UK
4. Functional measures to be undertaken include:
4.1. High flexion angle joint function measured using Fastrak electromagnetic motion tracking (Polhemus, USA)
4.2. High demand joint function (Sit to stand and squat) measured using Vicon T series (Oxford Metrics Oxford, UK)
A case/control design will be used to compare outcomes following surgery in patients receiving PFC sigma and CR150 implants. Patients will undergo the same range of evaluations as those described above at 3 months, 6 months and 1 year.
