Summary

Most total knee replacement patients can kneel comfortably, though many avoid it due to fear or advice. Actual kneeling ability after total knee replacement is often better than perceived.

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering
  • Rehabilitation medicine

Background:

  • Total knee replacement (TKR) is a common procedure for severe knee arthritis.
  • Assessing functional outcomes like kneeling is crucial for patient satisfaction.
  • Patient perception of kneeling ability may differ from actual capability.

Purpose of the Study:

  • To investigate the actual and perceived ability to kneel after uncemented primary total knee replacement.
  • To identify factors influencing kneeling ability and discomfort post-TKR.

Main Methods:

  • A study involving 75 patients (100 knees) assessed at least six months post-primary total knee replacement.
  • Patients were asked to comment on and demonstrate their ability to kneel.
  • Perceived and actual kneeling abilities were compared, noting discomfort levels and reasons for avoidance.

Main Results:

  • 64% of patients could kneel with no or only mild discomfort.
  • 32% of patients reported being able to kneel without significant discomfort.
  • 54% of patients avoided kneeling due to uncertainty or external recommendations, despite 64% having the physical ability.

Conclusions:

  • A majority of patients can physically kneel after total knee replacement, often without significant discomfort.
  • Perceived ability and actual ability to kneel can differ significantly post-TKR.
  • Barriers to kneeling are often psychological or social rather than purely physical limitations of the knee joint itself.
