Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Prehabilitation consists of at least 4 (and maximum 8) physiotherapy sessions prior to TKJR surgery. The prehabilitation sessions consist of exercises aimed at increasing strength and range of motion about the knee. Education regarding the processes and expectations following a TKJR are discussed and participants practice using pick up frames and crutches to increase familiarity with methods of mobilising post surgery. The sessions are aimed at improving overall fitness, mobility, strength and confidence leading into having TKJR surgery.

Prehabilitation will aim to be 2 sessions per week for 4 weeks prior to surgery, with each session lasting 30-45 minutes (depending on progress in each session).

Study design
Purpose of the study
Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects are invited to participate at a pre-admission appointment. Subjects nominate whether they choose to undergo prehabilitation or not. This is usual practice at the hospital where the trial will be undertaken.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
N/A
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Subjects nominate whether they will undertake the intervention or not. This is in line with usual practice at the hospital where the trial will take place.
Phase
Not Applicable
Type of endpoint/s
Efficacy
Statistical methods / analysis
Comparison of the rehabilitation and non-prehabilitation groups mean time to readiness for discharge, comparison of the mean length of stay between same groups, comparison of mean KOOS scores on discharge and 3 months later. In order to detect a difference of 0.5 days, with a SD of 3 days, 46 participants are needed per group to detect a difference with 95% confidence and 80% power. To allow for drop outs this number has been rounded up to 100.

Summary
Brief summary
A Total Knee Replacement (TKJR) is a common treatment for advanced osteoarthritis of the knee. Osteoarthritis is the wearing of the joint surfaces in the knee, over time becoming painful and severely limiting a person’s mobility. In a TKJR, worn joint surfaces of the knee are replaced with synthetic components, removing the source of pain and allowing a person to return to higher levels of function. However, the nature of the surgery means rehabilitation is required to allow the person to return to previous levels of activity.
A TKJR is an elective procedure with a long wait list in the public hospital system. Individuals with private health insurance can avoid a long wait for surgery and have the procedure conducted in a private hospital, with insurance covering the majority of the costs for surgery. Private health insurance also commonly covers some of the costs associated with physiotherapy treatment and rehabilitation.
Prehabilitation is the practice of exercising prior to a procedure to increase the strength and function of the body in order to speed up recovery after surgery. In the case of a TKJR, prehabilitation equates to increasing knee joint flexion, increasing strength in the muscles around the knee and improving general cardiovascular fitness. The ultimate aim of prehabilitation is to speed the recovery after surgery through the strengthening of major muscles groups beforehand.
It is current practice at St Vincent's Private, Kew, that patients undergoing a TKJR are given the option to undertake prehabilitation or not. This research aims to determine whether prehabilitation in a private hospital setting improves short -term outcomes after TKJR.
