This study found that a knee brace significantly reduced pain and improved function for patients with medial compartment arthrosis. While gait analysis showed no changes, the brace offered short-term relief and better daily living for most patients.

Area of Science:

  • Orthopedics
  • Biomechanics
  • Rehabilitation Medicine

Background:

  • Medial tibiofemoral compartment osteoarthritis causes chronic knee pain and functional limitations.
  • Conservative management options are sought to alleviate symptoms and delay surgical interventions.

Purpose of the Study:

  • To evaluate the effectiveness of a knee brace in reducing pain, improving function, and altering gait in patients with medial compartment arthrosis.
  • To assess patient-reported outcomes and objective functional measures after brace use.

Main Methods:

  • Eighteen patients with symptomatic medial compartment arthrosis were fitted with a knee brace.
  • Patients were evaluated for pain and function using validated scales at 9 weeks and 1 year.
  • A subset of patients underwent dynamic gait analysis and were compared to a healthy control group.

Main Results:

  • Statistically significant improvements in all pain parameters were observed at 9 weeks and persisted at 1 year.
  • Pain with activities of daily living decreased from 78% to 39% at 9 weeks and 31% at 1 year.
  • Walking tolerance without pain increased significantly, and overall knee condition ratings improved.

Conclusions:

  • The knee brace provided significant short-term pain relief and functional improvement for the majority of patients with medial compartment arthrosis.
  • While gait parameters did not change, the brace serves as a reasonable alternative for patients seeking to delay or avoid surgery.
  • Bracing offers a viable option for short-term symptom management in knee osteoarthritis.
