Valgus offloader bracing is an effective treatment for improving pain secondary to medial compartment knee osteoarthritis. The literature remains unclear on the effectiveness of valgus offloader braces with regard to functional outcomes and stiffness. Larger prospective randomized trials with consistent outcome assessment tools and consideration of patient compliance would be beneficial to more accurately determine treatment effects of valgus offloader bracing.

“…However, there is a wide variety of available knee braces, which complicates the choice of proper knee brace treatment for patients with KOA. In addition, studies rarely indicate the frequency and duration of brace wear, which affects the ability to modify guidelines to improve compliance 23,24 . Previous studies that observed the biomechanical effects of brace treatment duration were done on a few weeks 8,12,15,25 or compare gait without the brace pre‐treatment to brace wear posttreatment, 8,25,26 where the factors brace wear and time (treatment) cannot be dissociated.…”

Immediate biomechanical and functional effects of knee braces are often reported, however, the duration and type of knee brace treatment for knee osteoarthritis (KOA) remain unclear. The objective was to evaluate usage, comfort, pain, and knee adduction moment (KAM) of three knee braces each worn 3 months by patients. Twenty‐four patients with KOA were assigned in a randomized crossover trial a valgus three‐point bending system brace (V3P‐brace), an unloader brace with valgus and external rotation functions (VER‐brace) and a stabilizing brace used after ligament injuries (ACL‐brace). Functional questionnaires and gait assessment were carried out before and after each brace wear period of 3 months. A Friedman test was applied between brace wear diary recordings. Repeated measures analyses of variance contrasted the factors brace type (ACL, V3P, and VER), time (pre and post) and wear (without and with) on comfort, pain, function, and KAM. Brace usage was similar, but the V3P‐brace was slightly less worn. Discomfort was significantly lowered with the VER‐brace. All knee braces relieved pain and symptoms from 10% to 40%. KAM angular impulse was reduced with the three braces, but the VER‐brace obtained the lowest relative reduction of 9%. The interaction between time and wear indicated that part of the KAM reduction with brace wear was maintained post treatment. All three knee braces have great benefits for pain and function among the medial KOA population. The VER‐brace offers additional advantages on daily use, comfort and KAM, which could improve compliance to brace treatment.

“…Mean daily wearing time among patients was between 2 and 6 h which is comparable with findings in other studies where regular orthosis usage at an average of 5 h/day was stated. 39,40 However, some patients in our study also wore the orthosis for more than 10 h/day which widely exceeds regular daily wearing time. Patients generally rated the orthosis as handy and comfortable and intended further usage.…”

The orthosis provides significant biomechanical improvements, pain relief and good patient compliance. Patients had a biomechanical benefit for the individualised and reduced orthosis adjustments. Clinical relevance In patients with medial knee osteoarthritis, a lightweight medial unloader orthosis effectively reduced external knee adduction moment and pain sensation during daily activities. Thus, use of lightweight orthoses effectively supports conservative treatment in medial knee osteoarthritis.
