Do web-based follow-up surveys have a better response rate than traditional paper-based questionnaires following outpatient arthroscopic rotator cuff repair? A randomized controlled trial.

INTRODUCTION: Considering the extensive use of smartphones in current societies, web-based applications could be considered as a new option for patient follow-up in surgery. By means of such tool, automated and periodic questionnaires could improve the rigor, accuracy and the comprehensiveness of postoperative monitoring, as well as early detection of complications, especially in the current context of evolving ambulatory surgery. HYPOTHESIS: The web-based surveys would improve the quality of immediate postoperative monitoring. MATERIAL AND METHODS: For 7 months, we included all patients who underwent outpatient arthroscopic rotator cuff repair. After preoperative randomization, each patient was asked postoperatively to complete either paper-based forms or digital questionnaires via a website (Orthense.com®, Digikare Inc. Blagnac, France). Both media (i.e. paper and digital) followed the same postoperative agenda (i.e., D+3, D+14, D+28, D+45, D+90) and had the same content, including pain and discomfort assessments, functional scores (i.e. Shoulder subjective value, simple shoulder test and auto-constant scores). The main objective was to investigate the quality of postoperative follow-up after outpatient arthroscopic rotator cuff surgery, using either printed questionnaires or web-based surveys. The hypothesis was that using a web-based survey would result in greater response rates and increased patient satisfaction regarding follow-up. Primary outcomes were questionnaire response rates at D+45 and D+90, while secondary outcomes were overall response rates, patient recommendation for the monitoring medium and overall patient satisfaction regarding their follow-up using the net promoter score (NPS). RESULTS: Among the 59 consecutive patients who were included, there were 27 females and 26 males with a mean age of 57±10.2 years; 27 patients completed the web-based survey (Group A) and 26 patients answered paper-based questionnaires (Group B). Regarding the D+45 questionnaire, response rates were 85.2% (n=23) in group A and 42.3% (n=11) in group B (p=.005); a similar significant difference was observed regarding the D+90 questionnaire, with response rates of 70.4% and 34.6%, respectively (p=.027). The mean NPS for the survey was 10 in Group A and 8.29 in Group B (p=.016). Overall, satisfaction regarding postoperative care did not differ between the two groups. DISCUSSION: Compared to traditional paper-based forms, web-based surveys appear to increase patient adherence to short-term postoperative monitoring. If these findings were to be confirmed in long-term follow-up, such straightforward and cost-effective tool could be of great use in clinical care and research. LEVEL OF EVIDENCE: I; Randomized controlled clinical trial.

Tendon fixation in arthroscopic latissimus dorsi transfer for irreparable posterosuperior cuff tears: an in vitro biomechanical comparison of interference screw and suture anchors.

BACKGROUND: The fixation of the tendon to the bone remains a challenging problem in the latissimus dorsi tendon transfer for irreparable cuff tears and can lead to unsatisfactory results. A new arthroscopic method of tendon to bone fixation using an interference screw has been developed and the purpose of this study was to compare its biomechanical properties to the ones of a standard fixation technique with anchors. METHODS: Six paired fresh frozen cadaveric human humeri were used. The freed latissimus dorsi tendon was randomly fixed to the humeral head with anchors or with interference screw after a tubularization procedure. Testing consisted to apply 200 cycles of tensile load on the latissimus dorsi tendon with maximal loads of 30 N and 60 N, followed by a load to failure test. The stiffness, displacements after cyclic loadings, ultimate load to failure, and site of failure were analysed. FINDINGS: The stiffness was statistically higher for the tendons fixed with interference screws than for the ones fixed with anchors for both 30 N and 60 N loadings. Likewise, the relative bone/tendon displacements after cyclic loadings were lower with interference screws compared to anchors. Load to failure revealed no statistical difference between the two techniques. INTERPRETATION: Compared to the standard anchor fixation, the interference screw fixation technique presents higher or similar biomechanical performance. These results should be completed by further biomechanical and clinical trials to confirm the interest of this new technique as an alternative in clinical use.

In vitro biomechanical comparison of three different types of single- and double-row arthroscopic rotator cuff repairs: analysis of continuous bone-tendon contact pressure and surface during different simulated joint positions.

HYPOTHESIS: We assessed bone-tendon contact surface and pressure with a continuous and reversible measurement system comparing 3 different double- and single-row techniques of cuff repair with simulation of different joint positions. MATERIALS AND METHODS: We reproduced a medium supraspinatus tear in 24 human cadaveric shoulders. For the 12 right shoulders, single-row suture (SRS) and then double-row bridge suture (DRBS) were used. For the 12 left shoulders, DRBS and then double-row cross suture (DRCS) were used. Measurements were performed before, during, and after knot tying and then with different joint positions. RESULTS: There was a significant increase in contact surface with the DRBS technique compared with the SRS technique and with the DRCS technique compared with the SRS or DRBS technique. There was a significant increase in contact pressure with the DRBS technique and DRCS technique compared with the SRS technique but no difference between the DRBS technique and DRCS technique. CONCLUSIONS: The DRCS technique seems to be superior to the DRBS and SRS techniques in terms of bone-tendon contact surface and pressure.

The time for functional recovery after arthroscopic rotator cuff repair: correlation with tendon healing controlled by computed tomography arthrography.

PURPOSE: We investigated how soon postoperative functional recovery became significant after arthroscopic rotator cuff repair and the influence of tendon healing. METHODS: We conducted a prospective study on 114 cases of full-thickness rotator cuff tears arthroscopically repaired from January 2001 to December 2003. All patients were evaluated by the Constant scoring system at 3, 6, 12, and 24 months after surgery and at last follow-up. Computed tomography arthrography was done at 6 months postoperatively to study the progression of tendon healing. RESULTS: The Constant score significantly improved from the third month after surgery (P < .0001) until the twelfth month, after which it stabilized (P < .0001). At last follow-up (31 months), the mean score was 80.1 points (range, 50 to 95 points). Female sex (P < .0001), upper-limb heavy work (P < .0001), poor bone quality (P = .039), and absence of healing (P = .002) were negative predictive factors. In particular, the absence of tendon healing leads to a worsening of the results from the twelfth month onward. CONCLUSIONS: Arthroscopic repair of rotator cuff lesions as performed in this study gives very good results in terms of functional recovery. Our study showed functional recovery as early as 3 months after surgery and further improvement over the first year, followed by stabilization. We found that female sex, upper-limb heavy work, poor bone quality, and lack of tendon healing were all negatively associated with outcome. Patients presenting with a retear differed from the other patients, in that their clinical progression showed a significant rise in the Constant score over the first year, with a lowering of the score thereafter. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Can a double-row anchorage technique improve tendon healing in arthroscopic rotator cuff repair?: A prospective, nonrandomized, comparative study of double-row and single-row anchorage techniques with computed tomographic arthrography tendon healing assessment.

BACKGROUND: Increasing the rate of watertight tendon healing has been suggested as an important criterion for optimizing clinical results in rotator cuff arthroscopic repair. HYPOTHESIS: A double-row anchorage technique for rotator cuff repair will produce better clinical results and a better rate of tendon healing than a single-row technique. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: We compared 31 patients undergoing surgery with a double-row anchorage technique using Panalok anchors and Cuff Tack anchors and 35 patients with rotator cuff tear undergoing surgery with a single-row anchorage arthroscopic technique using Panalok anchors. We compared pre- and postoperative Constant score and tendon healing, as evaluated by computed tomographic arthrography 6 months after surgery, in these 2 groups. RESULTS: The Constant score increased significantly in both groups, with no difference between the 2 groups (P = .4). Rotator cuff healing was judged anatomic in 19 patients with double-row anchorage and in 14 patients with single-row anchorage; this difference between the groups was significant (P = .03). CONCLUSION: In this first study comparing double- and single-row anchorage techniques, we found no significant difference in clinical results, but tendon healing rates were better with the double-row anchorage. Improvements in the double-row technique might lead to better clinical and tendon healing results.

The effect of tourniquet use in total knee arthroplasty.

We conducted a prospective, randomised study on primary total knee replacements to evaluate the effects of tourniquet use on total calculated blood loss using Gross formula, post-operative measured blood loss, operating time, need for blood transfusion, post-operative pain, analgesia requirement and knee flexion. Forty patients were operated on with the use of an arterial tourniquet with pressure of 350 mmHg (group A), and 40 patients without the use of a tourniquet (group B). Total calculated blood loss was significantly increased ( P=0.0165) without the use of a tourniquet. There was no significant difference in measured blood loss or operating time. The median units of blood given were similar in both groups. In spite of autologous transfusions 14% of patients received additional homologous transfusions. At 6 h post-operatively pain was significantly less ( P=0.0458) in group B but was similar at 24 and 48 h. There was no significant difference in analgesia requirement. The mean change in total flexion in group B was significantly better ( P<0.001) at 5 days than in group A, but knee flexion was similar at 10 days and 3 months. Knee arthroplasty operations without the use of a tourniquet cause a greater blood loss but have only small benefits in the early post-operative period.
