  Purpose

Total knee arthroplasty (TKA) is performed more than 7.000 times a year in Finland most often for osteoarthritis (OA). While pain is predictably reduced, function does not typically ever reach that of age-matched, uninjured subjects. Quadriceps weakness has been implicated in the development and progression of knee OA and is a significant problem after TKA. Advance to return to normal daily activities is not sufficient to restore knee function or quadriceps strength after TKA.

The aim of this study is to assess the effectiveness of progressive exercise program restoring knee strength, mobility and improving the functional outcome after primary TKA.

Primary Outcome Measures:
  • Functional tests, pain [ Time Frame: baseline , 6 weeks after operation (start of training), after 12 months training ] [ Designated as safety issue: Yes ]
    Timed-Up and Go-test, Visual analogue scale (VAS)


Secondary Outcome Measures:
  • Knee muscle strength [ Time Frame: baseline, 6 weeks after operation (start of training), after 12 months training ] [ Designated as safety issue: Yes ]
    isometric strength of quadriceps and hamstrings

  • Health related quality of life [ Time Frame: baseline and 12 months ] [ Designated as safety issue: Yes ]
    SF-36

  • gait analysis [ Time Frame: baseline, 6 weeks postoperatively, 12 months ] [ Designated as safety issue: Yes ]

Enrollment: 120

Study Completion Date: December 2012
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: exercise
progressive exercise, home-based exercise program, tree exercise sessions weekly, chec-up visits every third month
Other: Knee muscle exercises
Home exercises three times a week, control every three months
Active Comparator: Conventional treatment
Normal treatment, single guidance to home exercise
Other: Knee muscle exercises
Home exercises three times a week, control every three months

Detailed Description:

Many studies have shown, that after TKA pain decreased significantly, but muscle strength of the operated knee did not recover and may stay under the preoperative level. To find out the effects of progressive exercise program the investigators will perform, 6 weeks after TKA, a randomized clinical trial of lower extremity strength training using two subgroups of people: traditional exercise group and progressive exercise group.
