Background and study aims
Arthroscopic, or keyhole, surgery on the meniscus in the knee joint has benefits over open surgery. Nonetheless, there is scope to further improve outcomes for patients by reducing pain and discomfort and promoting enhanced recovery of knee joint functionality. The medical device Viscoseal contains hyaluronan and is designed to replenish levels of this compound in the knee joint following arthroscopic repair of the meniscus. Natrually, synovial fluid in the knee joint contains hyaluronan, but a lot of it is washed away when surgeons flush the knee joint during surgery to remove loose pieces of meniscus, cartilage, or bone. Previous studies, both in laboratory studies and patient trials, have demonstrated that Viscoseal can promote re-establishment of biological structure in the knee joint to allow it to return to a normal physiological state and protect cartilage.
Who can participate?
Patients aged 18 – 59 years due to undergo meniscal surgery of the knee for meniscal tear grade III (including repair, partial meniscectomy or complete meniscectomy).
What does the study involve?
This present prospective, randomised, controlled trial aims to build on this evidence by comparing standard care versus the injection of Viscoseal (26 vs 26 patients) at the end of arthroscopic meniscus repair surgery. The degree of pain, leg swelling and knee functionality experienced by patients after surgery will be measured using validated patient surveys focused on the meniscus. In addition, a detailed picture of what happens to the meniscus after surgery +/- administration of Viscoseal will be obtained through MRI radiologic imaging. The main objective is to determine if Viscoseal can achieve a minimal clinically important difference in pain relief after meniscal repair surgery when compared to standard care.
What are the possible benefits and risks of participating?
Benefits: For participants in the control group there is no direct benefit for taking part in this study. You will be cared for in exactly the same manner as you normally would, bar the introduction of a few questionnaires and a potential extra MRI scan. However, by taking part you will contribute to comparison of the effectiveness of adding hyaluronate to a meniscus operation, to optimise management of meniscus surgery in the future. For participants in the Viscoseal® intervention group there may be benefits in terms of reduced pain and swelling after the procedure. However, this has not yet been proven and established beyond doubt, and this study is aimed to assess this further.
Risks: There is no significant personal safety risk anticipated regarding taking part in this study. Like with any invasive procedure, the meniscus surgery carries (post-operative) risks such as bleeding, blood clots and infection. However, the arhroscopic surgery itself is not classed as being part of this HIKE study; the injection of Viscoseal® at the end of the procedure is. Fifty percent of patients do not receive this and therefore for them there is no additional risk over and above that related to standard care.

Scientific title | A single-centre, randomised, placebo-controlled single-blinded trial assessing patient and clinical outcomes of Viscoseal injection after meniscal surgery |
Study acronym | HIKE |
Study objectives | To determine the level of index leg related pain experienced at day 7 post-operation and to compare the average pain scores of patients in the control and Viscoseal arm respectively, through administration of 100 mm visual descriptor scale (VDS) for pain at rest. |
Ethics approval(s) | Approved 22/01/2020, NHS HRA Wales REC 7 (c/o Public Health Wales, Building 1, Jobswell Road, St David’s Park, SA31 3HB, UK; +44 (0)1267 611 164; sue.byng@wales.nhs.uk), ref: 19/EM/0363 |
Health condition(s) or problem(s) studied | Elective orthopaedic surgery |
Intervention | - Standard care (control) arm All patients receive general anesthesia and a pneumatic tourniquet is used. Patients are already randomised prior to surgery to avoid delays with surgery and allow a vial of Viscoseal to be ready for the relevant patients. Joint irrigation is performed with the assistance of a manual arthroscopic pump using 0.9% NaCl solution at room temperature. Then, the remaining fluids are drained from the knee. At the end of the surgery, the knee is dressed while the tourniquet is still inflated. All surgeries are intended to be performed in a day-surgery facility with the patient being discharged the same day. Postoperatively, partial weight-bearing with crutches is allowed. Crutches are recommended for the first 48 hours, primarily for patient safety by minimising the risk of a fall. - Viscoseal (intervention) arm Apart from the difference in terms of Viscoseal administration to the intervention group, the surgical protocol for the Viscoseal arm is identical to that of the standard care group. At the end of the surgery, again all the remaining fluids are drained from the knee, but this is followed by injection of 10 mL of Viscoseal preparation. Used Viscoseal product and syringes will be disposed of in line with local guidelines on disposal of clinical waste.
