HYAJOINT Plus® is a synovial fluid supplement, also known as a viscosupplement, that replaces the hyaluronic acid naturally present in the joint. The treatment requires a single injection into the synovial cavity of the joint knee 3.
HYAJOINT Plus® reduces knee pain and improves mobility for at least 6 months 1,2.
Active Ingredient
Sodium hyaluronate 60mg
HA Concentration
60mg/3mL (2%)
Injection Regimen
One single injection per treatment for adult into the OA knee joint
Package
3mL x 1 syringe
*This product is a class III medical device. CE marked (Notified body n°2797) in accordance with the rules and regulation in effect. 
HYAJOINT Plus® is synthesised by a novel cross-linking process using 1,4-butanediol diglycidyl ether (BDDE) to create an antidegradation feature. The patented CHAPTM (Cross-linked Hyaluronic Acid Platform) process prolongs the degradation time by carefully transforming linear hyaluronic acid to crosslinked hyaluronic acid and thus increasing the molecular weight. This cross-linking technology enables the creation of a viscous gel with increased density (2% HA, 20mg/ml)1,2. The carefully controlled cross-linked hyaluronic acid increases the viscoelastic properties of the synovial fluid reducing pain and restoring knee joint mobility 1,2.
*For more information, please consult the available patent.
Linear hyaluronic acid before cross-linking.
Cross-Linking technology with less BDDE, minimising the amount of BDDE residue.
The values of VAS score (mm) are given as the mean ± standard deviation. For statistical detail, please refer to the brochure.
Better improvement of pain relief by 33.3 mm on VAS score in patients treated with HYAJOINT Plus® compared to 23.4 mm in the Synvisc-One® group at 6 months (mean difference between groups -6.6; p=0.045).2
The frequencies and types of adverse events were comparable between Synvisc-One® and HYAJOINT Plus® groups. The majority of adverse events were mild or moderate, lasted 1 to 3 days, and resolved spontaneously or responded well to simple analgesics. The adverse events reported in each group were joint pain, joint swelling, joint stiffness, limb weakness, back pain. Twelve patients ( 9 treated with Synvisc-One® and 3 treated with HYAJOINT Plus®) developed joint effusion within 1 week after the injection, all infections revolved except for 2 patients treated with Synvisc-One® who required arthrocentesis for pain relief. No allergies, pseudosepsis or serious adverse events occurred during the study in either group.2
6 months after injection of HYAJOINT Plus®, the WOMAC pain score (Western Ontario and McMaster Universities Osteoarthritis Index) was significantly reduced compared to the baseline (from 7.62 to 3.57; P<0.001)1.
The Single Leg Stance (SLS) duration was significantly improved at 6 months after HYAJOINT Plus® injection compared to the baseline (from 14.95 to 26.37 sec; p=0.008)1.
The mean VAS decreased by 28.45 mm from baseline at 6-month follow-up (from 60.12 to 31.67mm; p<0.001)1.
The values of WOMAC pain score (points) are given as the mean ± standard deviation (7.62±0.49 and 3.57 ±0.40 at baseline and 6 months respectively) in 46 patients assessed using a Bonferroni post-hoc test. Adapted from Tuan et al, 2018.
The values of SLS duration (sec) are given as the mean ± standard deviation (14.95±2.97 and 26.37±3.83 at baseline and 6 months respectively) in 46 patients assessed using a Bonferroni post-hoc test. Adapted from Tuan et al, 2018.
The values of VAS score (mm) are given as the mean ± standard deviation (60.12±2.31 and 31.67±25.02 at baseline and 6 months respectively) in 46 patients assessed using repeated measures one-way ANOVA and a Bonferroni post-hoc test. Adapted from Tuan et al, 2018.
HYAJOINT Plus®, should not be administered to patients who have experienced cases of past or present infections or skin diseases in the area of the injection site. Prior to injection, ask your patient if they have experienced hypersensitivity to any hyaluronic acid-based products. The injection of HYAJOINT Plus® must be administered by authorized personnel in accordance with local legislation.
