Study summary

The purpose of the study is to assess whether the REGENETEN™ Bioinductive Implant allows patients to get back to their everyday activities quicker than if the tendon is repaired by the standard repair technique 'Completion and Repair' for surgically treating partial-thickness rotator cuff tears.

Read the detailed description

The primary objective of this study is to evaluate the functional recovery of patients with high grade (>50%) partial thickness tears at 3 months when treated with either Isolated Bioinductive Repair (IBR) or Completion and Repair (CAR).

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Change in Western Ontario Rotator Cuff (WORC)

    The WORC Index is self-administered, and includes a 5 different domains (physical symptoms, sports and recreation, work, social function, and emotions). Each question uses a visual analog scale (VAS) representing a 100-point scale ranging from 0 to 100. The maximum score is 2100 (worst possible symptoms). Zero (0) represents no symptoms at all. The final score can also be presented as a percentage by subtracting the total from 2100, dividing by 2100, and multiplying by 100. This will give you an overall percentage. The total final WORC Index scores can, therefore, range from 0% (lowest functional status level) to 100% (highest functional status level).

    Time frame: Change from baseline to 3 months post-intervention

Secondary outcomes

  1. Western Ontario Rotator Cuff (WORC)

    The WORC Index is self-administered, and includes a 5 different domains (physical symptoms, sports and recreation, work, social function, and emotions). Each question uses a visual analog scale (VAS) representing a 100-point scale ranging from 0 to 100. The maximum score is 2100 (worst possible symptoms). Zero (0) represents no symptoms at all. The final score can also be presented as a percentage by subtracting the total from 2100, dividing by 2100, and multiplying by 100. This will give you an overall percentage. The total final WORC Index scores can, therefore, range from 0% (lowest functional status level) to 100% (highest functional status level).

    Time frame: Pre-op, 6 weeks, 3, 6, 12 and 24 months

  2. Constant-Murley Score

    The Constant-Murley Score is a validated assessment of pain and shoulder functionality. The Constant Score is divided into 4 subscales: pain (15 points; VAS score range of 0-15), activities of daily living (20 points; range 0=worst, 5=best), strength (25 points; 1 point given per 0.5 kg of weights raised), and range of motion - forward flexion, external rotation, abduction and internal rotation of the shoulder (40 points; range 0=worst, 10=best). The higher the score, the higher the quality of function.

    Time frame: Pre-Op, 3, 6, 12 and 24 months

  3. Subjective Shoulder Value (SSV) score

    The SSV is defined as a patient's subjective shoulder assessment expressed as a percentage of an entirely normal shoulder, which would score 100% (0% to 100% scale with 100% being normal).

    Time frame: Pre-Op, 6 weeks, 3, 12 and 24 months

  4. EuroQol 5 Dimension 5 Level (EQ-5D-5L) VAS & index scores

    To assess the subject's health state. The EQ-5D-5L is composed of the EQ- 5D-5L descriptive system and the EQ Visual Analogue scale (EQ VAS). The descriptive system comprises 5 dimensions (mobility, self care, usual activities, pain/discomfort, anxiety/depression). Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Responses are coded as single-digit numbers expressing the severity level selected in each dimension. For instance, 'slight problems' (e.g. 'I have slight problems in walking about') is always coded as '2'. The digits for the five dimensions are combined in a 5-digit code. The EQ- 5D-5L index value is derived by using the vendor supplied calculator to convert each 5-digit EQ- 5D-5L profile. The EQ VAS corresponds to a 20 cm vertical, visual analogue scale ranging from 'the best health you can imagine' to 'the worst health you can imagine'. A higher number is a better outcome.

    Time frame: Pre-Op, 3 and 6 weeks, 3, 6, 12 and 24 months

  5. Change in Western Ontario Rotator Cuff (WORC)

    The WORC Index is self-administered, and includes a 5 different domains (physical symptoms, sports and recreation, work, social function, and emotions). Each question uses a visual analog scale (VAS) representing a 100-point scale ranging from 0 to 100. The maximum score is 2100 (worst possible symptoms). Zero (0) represents no symptoms at all. The final score can also be presented as a percentage by subtracting the total from 2100, dividing by 2100, and multiplying by 100. This will give you an overall percentage. The total final WORC Index scores can, therefore, range from 0% (lowest functional status level) to 100% (highest functional status level).

    Time frame: Change from Pre-op to 6 weeks, 3, 6, 12 and 24 months

  6. Change in Constant-Murley Score

    The Constant-Murley Score is a validated assessment of pain and shoulder functionality. The Constant Score is divided into 4 subscales: pain (15 points; VAS score range of 0-15), activities of daily living (20 points; range 0=worst, 5=best), strength (25 points; 1 point given per 0.5 kg of weights raised), and range of motion - forward flexion, external rotation, abduction and internal rotation of the shoulder (40 points; range 0=worst, 10=best). The higher the score, the higher the quality of function.

    Time frame: Change from Pre-Op to 6 weeks, 3, 12 and 24 months

  7. Change in Subjective Shoulder Value (SSV) score

    The SSV is defined as a patient's subjective shoulder assessment expressed as a percentage of an entirely normal shoulder, which would score 100% (0% to 100% scale with 100% being normal).

    Time frame: Change from Pre-Op to 6 weeks, 3, 12 and 24 months

  8. Percent Achieving Minimal Clinically Important Difference (MCID) for Constant-Murley Score

    The Constant-Murley Score is a validated assessment of pain and shoulder functionality. The Constant Score is divided into 4 subscales: pain (15 points; VAS score range of 0-15), activities of daily living (20 points; range 0=worst, 5=best), strength (25 points; 1 point given per 0.5 kg of weights raised), and range of motion - forward flexion, external rotation, abduction and internal rotation of the shoulder (40 points; range 0=worst, 10=best). The higher the score, the higher the quality of function.

    Time frame: Pre-Op, 3, 6, 12 and 24 months

  9. Percent Achieving MCID for Western Ontario Rotator Cuff (WORC)

    The WORC Index is self-administered, and includes a 5 different domains (physical symptoms, sports and recreation, work, social function, and emotions). Each question uses a visual analog scale (VAS) representing a 100-point scale ranging from 0 to 100. The maximum score is 2100 (worst possible symptoms). Zero (0) represents no symptoms at all. The final score can also be presented as a percentage by subtracting the total from 2100, dividing by 2100, and multiplying by 100. This will give you an overall percentage. The total final WORC Index scores can, therefore, range from 0% (lowest functional status level) to 100% (highest functional status level).

    Time frame: Pre-op, 6 weeks, 3, 6, 12 and 24 months

  10. Percent Achieving MCID for Subjective Shoulder Value (SSV) score

Started Aug 2022 (actual). Primary completion is estimated for Apr 2027, 55 months after the start.

Of 252 interventional studies with no phase under Rotator Cuff Injuries, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 44. This study's planned 55 months is above that.

Since we started tracking on Sep 25, 2026, the dates moved once, on Sep 28, 2026: primary completion Aug 2026 → Apr 2027 and completion Jun 2028 → Feb 2029.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
