Over the top anterior cruciate ligament reconstruction in patients with open physes: a long-term follow-up study.

INTRODUCTION: Anterior cruciate ligament (ACL) rupture in skeletally immature athletes is becoming an injury with increasing incidence. Choices of treatment are still debated, including conservative management vs. various surgical techniques. The lack of long-term reports has been highlighted in the literature. AIM: To evaluate long-term results of ACL reconstructions performed in skeletally immature patients using the Over the Top technique with lateral extra-articular tenodesis. METHODS: Retrospective study. All surgeries performed by same surgeon. A total of 42 patients included. All patients had pre-operative radiological studies. SUBJECTS: 30 males and 12 females. Average age: 12.5 years (range 11-14 years). Average follow-up: 96.1 months. Clinical evaluation: Pedi-IKDC, Tegner-Lysholm, KT-1000 and plain radiographs. Standardized rehabilitation protocol. RESULTS: No instability or leg length discrepancy was recorded. Average pre-operative Tegner-Lysholm and Pedi-IKDC scores were 55 and 40, respectively, with a score of 94.8 (p < 0.05) and 94.78, respectively, at final follow-up (p < 0.05). Average post-operative (1 month) Tegner-Lysholm score: 75 (range: 62-79). Median post-operative Tegner activity: 8. Mean side-to-side (KT-1000): 1.2 mm. A total of 22 patients could go back to pre-injury sport activity, with an average rehabilitation of 7.3 months. DISCUSSION: A significant number of cases were included in our structured standardized study and follow-up. Functional scores were excellent overall. Excellent results are testified by a final achievement of 22 patients going back to pre-injury sport activity, which is in keeping with the literature. Our experience exhibited a low complication rate and no metalwork failure. We correlate our results to the use of the Over the Top technique with lateral extra-articular tenodesis. CONCLUSION: The studied procedure seems to be an excellent option and an effective, feasible and safe technique when treating ruptured ACLs in skeletally immature patients.

Can platelet-rich plasma have a role in Achilles tendon surgical repair?

PURPOSE: Our hypothesis was that the Achilles tendon healing process after surgical treatment would be promoted by PRP with a faster return to sports activities. METHODS: Thirty patients with Achilles tendon rupture and surgically treated with a combined mini-open and percutaneous technique were prospectively enroled in the study. Patients were alternately case-by-case assigned to Group A (control group; 15 patients) or Group B (study group; 15 patients). In Group B, PRP was locally infiltrated both during surgery and 14 days after surgery. Patients in both groups were followed up at 1, 3, 6 and 24 months post-operatively via physical examination, VAS, FAOS and VISA-A scales; ultrasonography (US) and MRI were also conducted at one and 6 months; at the 6-month follow-up, isokinetic and jumping capacity tests were also performed. RESULTS: The VAS, FAOS and VISA-A scale showed no difference between the two groups at 1, 3, 6 and 24 months post-operatively. Isokinetic evaluation showed no differences at both angular speeds. Jumping evaluation showed no difference at 6 months. Also US evaluation showed no differences. MRI data analysis before administration of gadolinium did not reveal significant differences between the two groups. Moreover, after intravenous injection of gadolinium, patients in Group B showed signal enhancement in 30 % of patients compared to 80 % in Group A at 6 months, as indirect evidence of better tendon remodelling (P < 0.05). CONCLUSIONS: A substantial equivalence in structural and functional results in Achilles tendon ruptures surgically treated with and without addition of PRP is shown by present study. Clinical results, morphological features and jumping capability were similar in both groups. The addition of PRP to the surgical treatment of Achilles tendon rupture does not appear to offer superior clinical and functional results. LEVEL OF EVIDENCE: IV.

Functional treatment in rotator cuff tears: is it safe and effective? A retrospective comparison with surgical treatment.

BACKGROUND: The aim of this study was to compare rehabilitation protocol and operative treatment in a population of patients with a diagnosis of small to medium rotator cuff tears (≤3 cm), the null hypothesis being that there would been no difference in terms of clinical outcomes and patient's satisfaction between the rehabilitation protocol and the surgical treatment. METHODS: Patients with small to medium supraspinatus tears were retrospectively enrolled in this study and divided in 2 groups: arthroscopic repair (group A, 20 patients) and reinstated (group B, 18 patients). At a mean follow-up of 18 months, both groups underwent clinical (Constant, QuickDash, VAS), dynamometric and ultrasonographic evaluation. RESULTS: In both groups a significant clinical improvement was registered compared to baseline. However, surgical treatment yielded better results in Constant (p=0.004), Quick-Dash (p=0.0012), VAS (p=0.048) and strength evaluation (p=0.0014). In group A the re-tear rate was 10%, while in group B only 11% of increased tear size was registered. CONCLUSION: At a short term follow-up, the surgical treatment of small to medium supraspinatus tears yielded better clinical outcomes compared to the rehabilitation protocol, with better strength outcomes and 10% re-tear rate. Nevertheless, physiotherapy still offers acceptable results and could be a valuable option in patients not undergoing surgery. LEVEL OF EVIDENCE: III.

Acromioclavicular third degree dislocation: surgical treatment in acute cases.

BACKGROUND: The management of acute Rockwood type III acromioclavicular joint (ACJ) dislocation remains controversial, and the debate about whether patients should be conservatively or surgically treated continues. This study aims to compare conservative and surgical treatment of acute type III ACJ injuries in active sport participants (<35 years of age) by analysing clinical and radiological results after a minimum of 24 months follow-up. METHODS: The records of 72 patients with acute type III ACJ dislocations who were treated from January 2006 to December 2011 were retrospectively evaluated. Patients were categorised into two groups. group A included 25 patients treated conservatively, and group B included 30 patients treated surgically with the TightRope™ system. Seventeen patients were lost to follow-up. All patients were evaluated at final follow-up with these clinical scores: Constant, University of California Los Angeles scale (UCLA), American Shoulder and Elbow Surgeons Scale (ASES) and Acromioclavicular Joint Instability (ACJI) and with a subjective evaluation of the patient satisfaction, aesthetic results and shoulder function. The distance between the acromion and clavicle and between the coracoid process and clavicle were evaluated radiographically and compared with preoperative values. Δ, the difference in mm between the distance at the final follow-up and at T0 in the injured shoulder, and α, the side-to-side difference in mm at follow-up, were calculated. Heterotopic ossification and postoperative osteolysis were evaluated in both groups. RESULTS: There were no major intraoperative complications in the surgical group. The subjective parameters significantly differed between the two groups. Constant, ASES and UCLA scores were similar in both groups (P > 0.05), whereas ACJI results favoured the surgical group (group A, 72.4; group B, 87.9; P < 0.05). All measurements of radiographic evaluation were significantly reduced in the surgical group compared with the conservative group. In group A, we detected calcifications in 30% of patients; in group B we detected two cases of moderate osteolysis and calcifications in 70% of patients. CONCLUSION: Although better subjective and radiographic results were achieved in surgically treated patients, traditional objective scores did not show significant differences between the two groups. Our results cannot support routine use of surgery to treat type III ACJ dislocations.

Functional evaluation of professional athletes treated with a mini-open technique for achilles tendon rupture.

INTRODUCTION: in this study we report the functional results of 36 professional athletes treated with a combined percutaneous and mini-open technique. METHODS: patients were evaluated with Victorian Institute of Sports Assessment-Achilles questionnaire (VISA-A), the objective 100-points Hannover scale and the Ergo-jump Bosco System device. RESULTS: at a mean 28- month follow-up no re-rupture cases were observed. Six patients had minor complications. The Ergo-jump Bosco System device showed no significant differences in the side-to-side evaluation in regard to strength (-0.94%) and elasticity (+2.44%), while a significant post-operative loss was detected in the endurance trials (-6.78%). The Hannover scale showed an average score of 94.5, while the VISA-A had an average of 93.1. Thirty-one patients resumed their pre-operative sports activity level within five months from surgery. CONCLUSIONS: our results showed that the combined mini-open and percutaneous repair is an effective treatment for professional athletes, with satisfactory clinical and functional results, lack of major complications and a quick return to professional sports activity.

Bilateral quadriceps rupture: results with and without platelet-rich plasma.

This article presents a 46-year-old man with bilateral atraumatic quadriceps rupture that occurred while he was descending stairs. The patient underwent surgery the day after the accident. In the left knee, quadriceps reinsertion was performed using a conventional technique. In the right knee, platelet-rich plasma (PRP), both in its liquid and semisolid patterns, was added intraoperatively. Ultrasonography and magnetic resonance imaging evaluations were performed 1, 6, and 24 months postoperatively. At 6 and 24 months postoperatively, clinical and functional evaluations also were performed. Clinical examination showed no differences between the knees, and functional scores were the same for both knees. Ultrasonographic evaluation showed bilateral persistent tendon thickening and gross echotexture abnormalities, with no side-to-side differences. Magnetic resonance imaging showed signals of vascularized granulation tissue in both knees, which was more evident in the right (PRP) knee at 1 month postoperatively, along with a better signal of scar tissue in the right knee at 6 and 24 months postoperatively. The use of PRP yielded no better clinical or functional results than the lack of its use. However, a more intense and significant reparative healing process occurred where the PRP was used, thus suggesting a more rapid completion of the healing process, although this effect seems to remain only a radiographic finding with no clinical correlation.
