Outcomes
Primary outcome [1] 307611 0
Retear rate of rotator cuff repair. 12 month MRI report will be checked by the consulting investigator and the Cuff tendon integrity will be documented according to the 5-stage Sugaya assessment system
Timepoint [1] 307611 0
12 months post rotator cuff repair
Secondary outcome [1] 352419 0
Change of range of motion from pre-operative using a goniometer, with the glenohumeral joint as reference.. Motion includes forward flexion, abduction/adduction, external/internal rotation. Range of motion will be recorded at the pre-operative visit by the orthopedic surgeons, and again at 6, 12, 24, and 48 weeks post-operatively

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Only the coordinating investigator will be aware of the patient's allocation, using a central computer. The principal investigators will be blinded of the patient's allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be done using a table generated from a computer program
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s

The people assessing the outcomes
The people analysing the results/data

Efficacy
Statistical methods / analysis
Nominal data will be expressed as means +/- SD, while categorical data will be expressed as mean, frequencies, +/- SD. The Mann-Whitney U-test will be utilized to determine significant difference in outcome measures between two groups. Friedman’s test will be used to determine significant difference in outcome measures over time.

Summary
Brief summary
The clinical outcome of arthroscopic rotator cuff repair including pain and ROM is generally favourable
Despite advances in surgical techniques for rotator cuff repair, postoperative non-healing of rotator cuff tendons (tendon re-tear) is a serious issue, with an incidence ranging between 20% and 95%.
Given that re-tear rate after cuff repair is a serious issue, a number of approaches have been investigated to improve rotator cuff repair healing including advancements in the fields of repair materials, repair techniques, biological augmentation and rehabilitation protocols.
In this study we examine the healing effect of HA after cuff repair taking in consideration that some in-vitro and animal studies have demonstrated a significant positive effect of HA on tendon healing. Moreover, the efficacy and safety of HA in some abdominal surgeries and as a non-surgical therapy in shoulder disorders has been widely reported.
