Presently, PRP use in tendon and ligament injuries has several potential advantages, including faster recovery and, possibly, a reduction in recurrence, with no adverse reactions described. However, only 3 randomized clinical trials have been conducted.
Purpose of this study is to conduct a meta-analysis comparing the results of open and arthroscopic Bankart repair using suture anchors in recurrent traumatic anterior shoulder instability. Using Medline Pubmed, Cochrane and Embase databases we performed a search of all published articles. We included only studies that compared open and arthroscopic repair using suture anchors. Statistical analysis was performed using chi-square test. Six studies met the inclusion criteria. The total number of patients was 501, 234 suture anchors and 267 open. The rate of recurrent instability in the arthroscopic group was 6% versus 6.7% in the open group; rate of reoperation was 4.7% in the arthroscopic group vs. 6.6% in open (difference not statistically significant). The difference was statistically significant only in the studies after 2002 (2.9% of recurrence in the arthroscopic group vs. 9.2% in open; 2.2% of reoperation in the arthroscopic group vs. 9.2% in open). Results regarding function couldn't be combined because of non-homogeneous scores reported in the original articles, but the arthroscopic treatment led to better functional results. Arthroscopic repair using suture anchors results in similar redislocation and reoperation rate compared to open Bankart repair; however, we need larger and more homogeneous prospective studies to confirm these findings.
This study demonstrates that anterior talofibular ligament and calcaneofibular ligament advancement using suture anchor fixation is an effective procedure for the treatment of chronic lateral ankle instability and allows immediate weightbearing.
The purpose of the study was to compare the recurrence rate of arthroscopic Bankart repair with suture anchors in collision vs noncollision athletes. Sixty-four patients who underwent arthroscopic shoulder stabilization using suture anchors for recurrent anterior dislocation were identified. Forty-three patients (22 collision and 21 noncollision) were evaluated at a minimum 24-month follow-up. The recurrence rate was reported, and functional outcomes (American Shoulder and Elbow Society, Western Ontario Shoulder Index, and Short Form 12) were evaluated. Statistical analysis was performed using chi-square test and Student's t test with a 95% confidence interval and a significance level set at a P value less than .05. The overall dislocation recurrence rate was 4.6% (2 of 43 patients); the dislocation recurrence rate in collision athletes was 9% (2 of 22 patients), and no redislocations occurred in noncollision athletes. No statistical differences existed in Western Ontario Shoulder Index score (73.5% in collision and 73.4% in noncollision athletes; P=.831), American Shoulder and Elbow Society score (91.2 in collision and 80.7 in noncollision athletes; P=.228), and Short Form 12 score (108.5 in collision and 101.2 in noncollision athletes; P=.083). Average external rotation loss was 6.8° in collision and 5.5° in noncollision athletes (P=.864). Ninety percent of collision athletes vs 95% of noncollision athletes were satisfied. Seventy-three percent of collision and 81% of noncollision athletes were able to return to sport at their preinjury levels. Collision athletes had higher recurrence rates after arthroscopic shoulder stabilization compared with noncollision athletes, but no statistical difference was found. Functional outcomes according to American Shoulder and Elbow Society, Western Ontario Shoulder Index, and Short Form 12 were similar.
Objective:In vitro and in vivo studies have proven a pro-anabolic and anti-catabolic activity within cartilage with the use of pulsed electromagnetic fields (PEMFs). This has piqued interest of sports physicians for its use in the treatment of early osteoarthritis (OA). The aim was to determine if the use of PEMFs in patients with early OA of the knee would lead to an improved clinical outcome.Study design:Prospective case series.Methods:Twenty-two patients aged between 30 and 60 years who underwent treatment with PEMFs (4-hour treatment per day, duration 45 days) were included. All patients presented with symptomatic early OA with grade 0-2 changes (Kellgren-Lawrence classification) at the pretreatment evaluation. Patients were evaluated before treatment, at 1- and 2-year follow-up using visual analogue scale for pain, International Knee Documentation Committee objective, Tegner, and Knee Injury and Osteoarthritis Outcome Scores.Results:A significant improvement in all scores was observed at 1-year follow-up (P = 0.008). At 2-year follow-up, results deteriorated but were still superior to pretreatment levels (P = 0.02). No adverse reactions or side effects were seen.Conclusions:This study showed that the use of PEMFs in patients with symptomatic early OA of the knee led to significant improvement in symptoms, knee function, and activity at 1-year follow-up. There was a significant decline in all the scores at 2-year follow-up.
Heterotopic ossification is a condition characterized by the presence of mature lamellar bone and often bone marrow in soft tissues surrounding a major joint. It represents a common complication after total hip arthroplasty (THA). The etiology and predisposing factors are not completely known, but some authors reported that the implant of a non-cemented prosthesis seems to be associated with a greater incidence of HO. Two hundred and two non-cemented total hip arthroplasties were performed between October 1997 and February 2002. The mean age was 70.2 years. The average follow-up for 181 hips included in the study was 96 months (range, 72-120 months). A standard lateral approach (Hardinge) was performed for the implant of a non-cemented femoral component and a non-cemented acetabular component. Radiographs were done before and after surgery, at 1, 4 and 12 months postop, then every year. The incidence of HO was assessed in the antero-posterior view at each interval and graded according to Brooker classification. Out of 181 implants, HO was observed in 52 hips (28,7%). Heterotopic bone was graded as class I in 32 (17.7%) hips, class II in 14 (7.73%) hips, class III in 6 (3,3%) hips and class IV in none (0%). The mean preoperative Harris hip score was 48; at the last follow-up, the mean postoperative score was preoperatively to a mean of 89 points (range, 76-97 points) in HO Hip and of 91 points (range, 78-100 points) in the other Hip. In our experience, non-cemented THA led to a higher incidence of class I and II HO according to Brooker Classification, the incidence of HO is comparable to the rates reported in recent studies about the HO finding after a non-cemented THA, the importance of clinical symptoms in the presence of HO is very low.
Childhood flexible flat foot is the most common paramorphism of the lower limb. The cause is not a bony malformation of the foot but a functional deficiency of the anatomic structures supporting the plantar arch. These structures, working as active tie rods (the tibialis anterior and posterior muscles) or passive factors of support (flexor hallucis longus and flexor digitorum longus muscles) act together to maintain the plantar arch. Their deficiency is responsible for childhood flexible flat foot, characterized by a flattening of the plantar arch and calcaneus pronation (heel valgus) and manifested in the characteristic "duck walking" in children. Hypothesizing poor extensor activity of the tibialis anterior, extensor digitorum longus, and extensor hallucis longus muscles during the heel contact phase of the gait cycle, we began a preliminary study to evaluate, through superficial electromyography (sEMG), the activation of muscle groups involved in the pathogenesis of childhood flexible flat foot, in particular the tibialis anterior and extensor hallucis longus muscles, to plan a rehabilitative program addressing the strengthening of insufficient muscles. The therapeutic program should also include the use of a medial elastic push orthosis. Data obtained by sEMG highlight a reduced activation of muscles related to the grade of flat foot, emphasizing the concept that a reduced activation of extensor muscles may be involved in determining flexible flat foot.
