Retrospective Data Collection and Prospective Clinical Investigation for the Augmentation or Reinforcement of the Rotator Cuff Using the Pitch-Patch
- Conditions
- Rotator Cuff TearRotator Cuff InjuriesRotator Cuff Tears of the ShoulderRotator Cuff Tears
- Registration Number
- NCT05906004
- Lead Sponsor
- Xiros Ltd
- Brief Summary
This is a clinical investigation study. It will verify the long-term safety and performance of the Pitch-Patch when implanted to reinforce partially repairable rotator cuff tears and used as described by the manufacturer's instructions.
The medical device in this study is already on the market and is manufactured by Xiros Ltd.
The Pitch-Patch is a single-use polyester prosthesis available in two sizes (30x20mm and 35x25mm). It is reinforced around the perimeter and around each eyelet to provide strength and stability to the device and repair.
The study will collect data on patients who meet the entry criteria and have received the device.
This is a single-armed study, meaning all patients will have a Pitch-Patch. The total length of the is expected to be 4 years; this includes a recruitment period of 2 years, and a follow-up period (for the prospective clinical investigation) of 2 years.
A minimum of 32 patients will be enrolled into the study. Follow-up data will be collected at (if available for retrospective data) 3 months, 6 months, 1 year, 2 years and final follow-up (maximum 2.5 years for prospective study; maximum of 5 years for retrospective study).
- Detailed Description

- Target Recruitment
- 32
- Treated using Pitch-Patch device for augmentation or reinforcement of the rotator cuff since 2012.
- If applicable, patient is willing to participate in the study (beyond standard of (routine) care) and have been informed of the nature of the study, agree to its follow-up and have provided written informed consent as approved by the Ethics Committee (EC).

- Primary Outcome Measures
Name Time Method Device Related or Procedure Related Adverse Events 2 years Device related and/ or procedure related adverse events up to at least 2 years after surgery
Constant Murley Score (CMS) 2 years The primary performance endpoint is the change in the CMS from baseline (if available) and between post-surgery timepoints up to at least 2 years after surgery.
CMS comprises of 4 parts: Pain reported by the patient (max 15 points), activities of daily living reported by patient (max 20 points), range of movement assess by the examiner (max 40 points), and strength assessed by the examiner (max 25 points).
Scores range from 0 to 100. Better functioning shoulders will have a greater number of points, up to a maximum of 100 points.
- Secondary Outcome Measures
Name Time Method Normal Daily Work/ Normal Recreational Activities 2 years Ability to perform normal daily work and normal recreational activities measured by CMS post-surgery.
A subscale for Constant Murley Score, reported by the patient. Points range from 0-20, the higher the score, the higher the ability to perform normal daily work/ recreational activities.Tissue Integration into the Pitch Patch 2 years Tissue integration into the Pitch Patch will be assessed up to the 2 year time point and categorised into 'yes' or 'no' by the examiner. Tissue integration can be assessed from the following:
* Radiological data
* Histological data
* Photographic dataSubjective Shoulder Value 2 years Change in Subjective Shoulder Value (SSV) score from baseline and between post-surgery timepoints.
SSV is measured on a percentage scale from 0% to 100%, with a higher percentage reflecting a subjective feel of a normal shoulder.Re-tear Rate 2 years Number of re-tear events as assessed by radiographical imaging (e.g., MRI, Ultrasound)
Constant Murley Score (subscale) 2 years Change in CMS subscale scores (pain, activities of daily living, strength, and range of movement) from baseline and between post-surgery timepoints.
CMS subscales: Pain reported by the patient (max 15 points), activities of daily living reported by patient (max 20 points), range of movement assess by the examiner (max 40 points), and strength assessed by the examiner (max 25 points).
The higher the score, the higher the shoulder function.Tegner Score 2 years Change in Tegner Score from pre-injury and pre-surgery to post-surgery and between post-surgery timepoints.
The Tegner activity is a scale to identify graded level of activity of a patient. The scale ranges from 0 (very low level of activity) to 10 (extremely active). A score greater than 6 is only achievable with participation in sport.
