SUMMARY: This study reports the results of using a custom-made knee orthosis, the V-VASTM as an alternative to surgical intervention INTRODUCTION: Various orthosis designs exist for the management of patients with osteoarthritis of the knee. Custom or o -the-shelf unloader knee orthoses are widely used for relieving pain during weight bearing activities in patients with uni-compartmental osteoarthritis. Although these designs can be mechanically successful, patient tolerance may be low due to a higher concentration of pressures being exerted by straps or condylar pads. This is especially so with severe deformity and can limit the duration over which an orthosis can be tolerated. The authors have applied a new custom orthosis design (V-VASTM) in an experience of over 100 ttings. This design was investigated due to its ability to ne-tune comfort levels at tting, its light weight and relatively e cient biomechanical design. METHODS: The Varum Valgum adjustable stress (V-VAS™) custom knee orthosis is a new concept for treating patients who present with medial or lateral compartmental arthropathies. Its design incorporates features intended to increase both e ectiveness and compliance. Instead of using a narrow frame as seen on most designs, it uses a total contact cu on the thigh and tibia along with an adjustable, self aligning, polycentric joint system to create four points of pressure instead of three. There is no need for a condylar pad. This results in increased comfort.
At the tting stage, the design of the orthotic joint was such that ne adjustments of the amount of o oading were possible. Immediate feedback on pain relief was a very positive aspect of the design. By encouraging the patient to walk up and down stairs ar the tting stage, the orthotist was able to ne tune the brace performance without the need to remove and reapply. Radiological assessment before and after use and the decrease in pain on movement were the primary methods of measurement of clinical e ectiveness. RESULTS: Due to the age range it was important the brace was simple to apply, lightweight and neat in appearance as a high level of compliance was important. The aim of the bracing strategy was to reduce as much as possible the pain levels and where appropriate, increase levels of mobility. Group 1- All patients were asked after 6 weeks if they would willingly return the device - All refused.
Sample Case ( MD - 47yrs ) History t 1985 left knee arthroscopy & open medial menisectomy t 1995 repeat arthroscopy shows complete loss of medial chondral surface t 2005 right knee arthroscopy - bone on bone contact. Both knees moderate PFJ and lateral compartment chondral loss. Examination t Bilateral clinical varus >20 degrees t Both knees lack 5 degrees full extension t Moderate e usion right knee only t Severe pain and swelling right knee Observations t Too young for joint replacement t Too severe for chondral resurfacing t Too advanced for high tibial osteotomy t May be suitable for Benjamin’s double osteotomy Interpretation of Outcomes t Brace initially used 2 - 4 hours per day t Now used during working day t Excellent reduction in pain and swelling of right knee t Weight-bearing Xray t No brace 11 deg Varus t With brace 4 deg Varus
The system’s self-aligning, polycentric hinge design, has a means of linearly adjusting the varum or valgum angle (depending on which compartment is a ected) without causing mechanical joint binding. Even with quite severe deformity the joints t close to the knee without binding.
The two main patient groups selected for the V-VAS were those presenting with valgus /varus deformity of the knee in excess of 10 degrees and medically un t for surgery (GROUP 1), or those too young to be considered for knee replacement surgery (GROUP 2). In Group 2, bracing was seen as an earlier option than osteotomy and could be used in conjunction with pain-relieving injection therapy Patients liked the fact that the design closely followed the pro le of the knee without binding. Each patient was assessed radiographically and a custom cast made of the knee. Partial correction of deformity by the orthotist during cast taking was found to be important in minimising user discomfort. The patient’s perception of pain was used as an indicator of the optimum position during cast taking. It is likely that by demonstrating that pain relief could be achieved during casting, the patients expectations of the brace were raised.

All patients reported reduction in their pain by 50-70% using a simple 1-10 visual-analogue pain scale. Over 50% reported an increase in mobility in terms of their day to day tasks. Based on their individual experience, patients had a further 5cm distraction added at this point. In all cases the patients reported that the quality of life outcomes exceeded their expectations. Group 2 - One patient found the brace di cult to use due to a hypersensitivity following trauma and derived little or no bene t. One patient had initial bene t, reporting 50% pain reduction, however went on to elect for surgery . The remainder reported reduction in pain by 50-70%. They were not willing to go without their brace. Mobility was improved with around 10% returning to some form of activity such as the gym or hill walking. Two patients who were clinically obese reported migration of the brace in-situ as a problem. CONCLUSION: The V-VAS was found to be an ethical and e ective device in both study groups with 90% demonstrating signi cantly improved pain and mobility REFERENCES: 1. 2.

V-VAS™ A NEW CONCEPT IN CUSTOM OFFLOADING KNEE ORTHOSIS DESIGN Joseph W. Whiteside CO The use of custom or off-the-shelf unloader knee orthoses in both single and double upright design configurations have been successfully used in the management of patients with medial compartment osteoarthritis of the knee1-5. The mechanism to achieve this is a three point pressure system which creates an offloading moment of the affected compartment. How this offloading moment is achieved, is through a fixed or an adjustable structural frame being used as a counterforce to an adjustable strap(s) and/or an adjustable condylar pad that act as a corrective force. In more recent designs, a lengthening adjustment has been added to the proximal upright that allows for an angular shifting of the forces to create the offloading moment. Studies have shown that the offloading forces exerted by these devices are successful in relieving pain in those patients with uni compartmental osteoarthritis during weight bearing activities2,3,6. Although these designs have been successful, many times there is a certain degree of intolerance to the unloader knee orthosis that is experienced by the patient. This intolerance is typically due to a higher concentration of pressures being exerted by the strap or condylar pad, which can limit duration of use. As offloading adjustments are being made in the double upright designs, the frame configurations of the unloader orthosis do not follow a natural progression as oriented to the long axis of the leg when viewed in the coronal plane. As the corrective forces are applied to obtain the optimal offloading moment, there is an inability to distribute these forces proportionally through the leg. This leads to an inability to better match the center of rotation of the leg as viewed in the coronal plane, which can further limit compliance. In addition, the three points of pressure used in both designs are applied by laterally or medially shifting the femur and/or tibia to offload the affected compartment. This lateral or medial shift causes a certain amount of shear to the mechanical knee joint(s) resulting in a varying degree of binding with in the mechanical joint(s). This mechanical binding can further restrict the patients ability to freely flex and extend there knee during various activities of daily living. This shifting of the uprights and binding of the mechanical joint(s) that are felt by the patient can decrease the ability for the patient to comply with a single or double upright unloader knee orthosis. The Varum Valgum Adjustable Stress (V-VAS™¹) custom unloader knee orthosis is a new concept in treating patients who present with medial or lateral compartmental arthropathies. Its custom design incorporates several unique features that increase the effectiveness and compliance for the patient who is in need of an unloader orthosis. ¹ V-VAS™ is fabricated and distributed by Anatomical Concepts Inc., Poland, OH 44514-3250

V-VAS™ A NEW CONCEPT IN UNLOADER KNEE ORTHOSIS DESIGN Instead of using a narrow frame as seen on most all double and single upright designs it uses a total contact cuff on the thigh and tibia along with a unique adjustable self aligning polycentric joint system to create four points of pressure instead of three. With two points of pressure being applied as a counter force (located at the proximal and distal ends of the thigh and tibial cuffs on the affected side of the leg) and two points of pressure applied as the corrective force (located at the distal and proximal ends of the thigh and tibial cuffs respectively on the non affected side of the leg) to offload the affected compartment, there is no need for a condylar pad. As compared to the single upright design, the use of a counterforce strap is not necessary once again, due to the four points of pressure used to create the offloading moment. Its self aligning polycentric hinge design, features an efficient and effective means of linearly adjusting the varum or valgum angle (depending on which compartment is affected) without causing mechanical joint binding. This is a very practitioner friendly design due to the mechanical joint never needing re-squared. The V-VAS™ has been very effective in the clinical management of patients with symptomatic medial compartment osteoarthritis. Other successful applications include, lateral compartment osteoarthritis on patients with no abnormal genu valgum alignment up to 30º of semi flexible genu valgum, non-operative tibial plateau fractures, failed hardware or reconstruction of the tibial plateau, tibial plateau and or femoral condyle spacers and post total knee arthroplasty. The V-VAS™ is currently available in a custom design. The finished design consists of a polypropylene constructed posterior opening thigh and tibial cuff that include a corrugation, to increase transverse plane integrity. The V-VAS™ is secured to the extremity via a Velcro® popliteal strap, wrap around thigh and distal tibial cuff straps. The thigh and tibial cuffs are connected via a medial and lateral self aligning polycentric knee joint. One of the self aligning joints (placed on the affected side of the leg) has the ability to be lengthened linearly at its proximal and distal ends. The lengthening can be adjusted proportionally or disproportionately proximally (thigh) and/or distally (tibia) to accommodate varying proportions of soft tissue compression. This linear (lengthening) adjustment is achieved via a counter clockwise rotation of the adjustment screw. The opposing self aligning polycentric joint in the V-VAS™ design is static and functions as a fulcrum to the adjustable self aligning polycentric joint. This ability to lengthen the upright in a linear motion allows for an anatomically correct varum or valgum force to be applied to the femur and tibia through the soft tissues via the thigh and tibial cuffs respectively. The ability to lengthen the adjustable upright either proportionally or disproportionately is how the optimal offloading moment is achieved. The self aligning joints in combination with the linear adjustment are at the heart of the uniqueness of the VVAS™. The joint construction consists of a polycentric design that allows for a medial or lateral pivoting motion in the coronal plane. This pivoting motion is achieved through the use of two spherical bearings that are at each axis within the joint head. This design feature not only allows for uninhibited flexion and extension to 180º, but an ability to compensate for varying degrees of angulations as viewed in the coronal plane within the joint head. This ability to pivot accommodates the elongation of either the proximal and/or distal upright, resulting in the self aligning feature.

V-VAS™ A NEW CONCEPT IN UNLOADER KNEE ORTHOSIS DESIGN Suspension and anti-migration are accomplished through a removable silicon laden popliteal strap pad and tibial cuff pad. Comfort is further achieved through a removable thigh cuff liner. In a resent case study of a 51 year old male, 5'11" tall and weighing 220 pounds. The radiographs of the treated leg showed a 5º or 5 mm improvement in lateral condyle separation while fully weight bearing, using the V-VAS™ (Figure 1) versus the radiograph of the non-treated leg (Figure 2). This offloading moment of the lateral compartment allowed this patient to ambulate with minimal pain while wearing the orthosis.
Figure 1. Shows an increase in the lateral condyle space of 5º or 5mm in a full weight bearing position while wearing the V-VAS™ offloading custom knee orthosis.
Figure 2. Shows the collapsed lateral condyle space in a full weight bearing position when no orthotic intervention is used.
There are many design options available to those patients needing offloading knee orthoses. We know from reviewing literature that offloading orthoses are both ethical and very effective. There application will minimize use of medication, delay arthroplasty in the younger patient and control pain in those patients with co morbidity. They are also used as a pre-operative tool or post operative tool to determine the success of a surgical technique or offloading of the operative compartment respectively. As health care professionals we should strive for optimal outcomes when recommending various designs. Compliance, effectiveness and efficiency in design are all key factors in achieving this optimal result in the current healthcare arena. The unique features in this new design are an efficient and effective alternative used to achieve optimal results. REFERENCES 1. Finger S, Paulos LE.

Joint System and How Does it Function? The V-Vas joint system is a patented polycentric knee joint design with spherical bearings at each of the mechanical joint head axes. The ability for the joint to self align eliminates the time that would be normally spent realigning the mechanical joint and uprights. Thus, maintaining a smooth free motion action. This unique design allows the practitioner to provide an adjustable and gentle corrective force to the deformity. Adjustments can consist of a vara or valga angle adjustment of the tibia or femur independently, or varum or valgum angle adjustment of the knee. The degree of adjustment is dependent on the patientâ&#x20AC;&#x2122;s clinical and radiographic presentation. As the various adjustments are made, the V-Vasâ&#x201E;˘ joints accommodate the change in alignment through its self aligning abilities as seen in the photographs below.

The Pentagon™ is a posterior fitting, single upright knee orthoses that provides the orthopedic/rehabilitation team with a patient-friendly alternative to the traditional bulky double upright hinged knee configuration.
single release lever 15˚ increments
The double hinge orthoses are more difficult to utilize due to the sheer nature of the proper fitting standards. They are more time consuming to employ and more prone to cause additional follow up visits to address functional and comfort complications.
ROM adjustment in flexion and/or extension from 0˚ to 110˚

Total Motion Lock – lock out in
Knee immobilizers are simple to use, but lack the joint control that is so often desired in the rehabilitation process. Other methods that utilize static attachment of the thigh and calf cuff to a posterior knee joint essentially cause the knee joint to misalign due to a friction moment.

Free Motion –
0˚ to 110˚
The Pentagon™ orthoses is the only system that allows the calf and thigh segments to dynamically shorten and lengthen with the patient’s extremity during flexion and extension of the knee.
Free Motion
Cam Assembly
Rom settings will not be true if the settings are being checked with the Knee Orthosis off the patient’s extremity
Compensation for this shortening and lengthening is through the use of a free motion cam that is incorporated into the thigh and calf cuffs. With this unique feature comfort and function is achieved through out the full ROM of the knee orthosis. This design utilizes accurate alignment of the mechanical knee joint to that of the anatomical knee joint aiding in positive outcomes.
Also available in ROM-only version
This system design also allows for a simplified fitting of the knee orthoses. The unique Pentagon™ design can address up to five different knee orthoses functions: • • • • •
