Abstract

ABSTRACT: BACKGROUND: Athletes competing in sports that require running, changes in direction, repetitive kicking and physical contact are at a relatively higher risk of experiencing episodes of athletic groin pain. To date, there has been no systematic review that aims to inform clinicians about the best available evidence on features of exercise interventions for groin pain in athletes. The primary aim of this systematic review was to evaluate the available evidence on the effectiveness of exercise therapy for groin pain in athletes. The secondary aim of this review was to identify the key features of exercise interventions used in the management of groin pain in an athletic population. METHODS: MEDLINE, CINAHL, PubMed, SPORTSDiscus, Embase, AMED, Ovid, PEDro, Cochrane Controlled Trials Register and Google Scholar databases were electronically searched. Data relating to research design, sample population, type of sport and exercise intervention was extracted. The methodological evaluation of included studies was conducted by using a modified quantitative critical appraisal tool. RESULTS: The search strategy identified 468 studies, 12 of which were potentially relevant. Ultimately five studies were included in this review. Overall the quality of primary research literature was moderate, with only one randomised controlled trial identified. All included studies provided evidence that an exercise intervention may lead to favourable outcomes in terms of return to sport. Four of the five studies reviewed included a strengthening component and most utilised functional, standing positions similar to those required by their sport. No study appropriately reported the intensity of their exercise interventions. Duration of intervention ranged from 3.8 weeks to 16 weeks. All five studies reported the use of one or more co-intervention. CONCLUSION: Best available evidence to date, with its limitations, continues to support common clinical practice of exercise therapy as a key component of rehabilitation for groin pain in athletes. Overall, the available evidence suggests that exercise, particularly strengthening exercise of the hip and abdominal musculature could be an effective intervention for athletes with groin pain. Literature provides foundational evidence that this may need to be in the form of progressive exercises (static to functional) and performed through range. There is currently no clear evidence regarding the most effective intensity and frequency of exercise, because of a lack of reporting in the primary literature.

Abstract

OBJECTIVE: To assess the impact of the laparoscopic inguinal release procedure with mesh reinforcement on athletes with groin pain. DESIGN: Prospective cohort study. SETTING: Private sector. PATIENTS: Professional and amateur sportsmen/women undergoing the inguinal release for groin pain. MAIN OUTCOME MEASUREMENTS: Change in patient's symptoms, functional limitation and time to resuming sporting activity following surgery. RESULTS: 73 sportsmen/women underwent laparoscopic inguinal release in the study period, 37 (51%) of whom were professionals. 95% were male with a median age of 30 years. Following operation, patients returned to light training at a median of 1 week, full training at 3 weeks (professionals-2 weeks) and playing competitively at 4 weeks (professionals-3 weeks). 74% considered themselves match-fit by 4 weeks (84% of professionals). Following surgery, there was a highly significant improvement in frequency of pain, severity of pain and functional limitation in both the whole cohort and professional group. 88% reported a return to full fitness at follow-up, with 73% reporting complete absence of symptoms. 97% of the cohort thought the operation had improved their symptoms. CONCLUSIONS: This study shows that the laparoscopic inguinal release procedure may be effective in the treatment of a subgroup of athletes with groin pain.

Abstract

BACKGROUND: Adductor dysfunction can cause groin pain in athletes and may emanate from the adductor enthesis. Adductor enthesopathy may be visualized with magnetic resonance imaging and may be treated with entheseal pubic cleft injections. We have previously reported that pubic cleft injections can provide predictable pain relief at one year in competitive athletes who have no evidence of enthesopathy on magnetic resonance imaging and immediate relief only in patients with findings of enthesopathy on magnetic resonance imaging. In this follow-up study, we attempted to determine if the same holds true for recreational athletes. METHODS: We reviewed a consecutive case series of twenty-eight recreational athletes who had presented to our sports medicine clinic with groin pain secondary to adductor longus dysfunction. A period of conservative treatment had failed for all of these athletes. The adductor longus origin was assessed with magnetic resonance imaging for the presence or absence of enthesopathy. All patients were treated with a single pubic cleft injection of a local anesthetic and corticosteroid into the adductor enthesis. The patients were assessed for recurrence of symptoms at one year after treatment. RESULTS: On clinical reassessment five minutes after the injection, all twenty-eight athletes reported resolution of the groin pain. Fifteen patients (Group 1) had no evidence of enthesopathy on magnetic resonance imaging, and thirteen patients (Group 2) had findings of enthesopathy on magnetic resonance imaging. At one year after the injection, five of the fifteen patients in Group 1 had experienced a recurrence; these recurrences were noted at a mean of fourteen weeks (range, seven to twenty weeks) after the injection. Four of the thirteen patients in Group 2 had experienced a recurrence of the symptoms at one year, and these recurrences were noted at a mean of eight weeks (range, two to nineteen weeks) after the injection. Overall, nineteen (68%) of the twenty-eight athletes had a good result following the injection. Of the remaining nine athletes, two were treated successfully with repeat injection; therefore, overall, twenty-one (75%) of the twenty-eight athletes had a good result after entheseal pubic cleft injection. CONCLUSIONS: Most recreational athletes with adductor enthesopathy have pain relief at one year after entheseal pubic cleft injection, regardless of the findings on magnetic resonance imaging. There were similarities between this group of recreational athletes and the competitive athletes in our previous study, in that the adductor enthesis was the source of pain and entheseal pubic cleft injection was a valuable treatment option. The main difference was that, in this group of recreational athletes, magnetic resonance imaging evidence of adductor enthesopathy did not correlate with the outcome of the injection.

Abstract

PATIENTS AND METHODS: Chronic adductor-related groin pain in athletes is debilitating and is often challenging to treat. Little is published on the surgical treatment when conservative measures fail. This single center study reviews the outcomes of 48 patients (68 groins) who underwent percutaneous adductor tenotomy for sports-related chronic groin pain. Questionnaire assessments were made preoperatively and at a minimum follow-up of 25 months. RESULTS: Mean pre-injury Tegner activity scores of 8.8 reduced to 6.1 post-injury and these improved to 7.7 following surgery (p < 0.001). Sixty percent of patients regained or bettered their pre-injury Tegner activity scores after the adductor surgery; however, mean post-surgical Tegner scores still remained lower than pre-injury scores (p < 0.001). No patient had been able to engage in their chosen sport at their full ability pre-operatively, and 40% had been unable to participate in any sporting activity. The mean return to sports was at 18.5 weeks postoperatively, with 54% returning to their pre-injury activity levels, and only 8% still unable to perform athletic activities at latest follow-up. Seventy-three percent patients rated the outcome of their surgery as excellent or very satisfactory, and only three patients would not have wished to undergo the procedure again if symptoms recurred or developed on the opposite side. No patients reported their outcome as worse. A 78.1% mean improvement in function and an 86.5% mean improvement in pain were reported, and these two measures showed statistically significant correlation (p = 0.01). Groin disability scores improved from a mean of 11.8 to 3.9, post-operatively (p < 0.001). Bruising was seen in 37% of procedures, 3 patients developed a scrotal hematoma and 1 patient had a superficial wound infection. One patient developed recurrent symptoms following re-injury 26 months post-surgery, and fully recovered following a further adductor tenotomy. CONCLUSIONS: Adductor tenotomy provides good symptomatic and functional improvement in chronic adductor-related groin pain refractory to conservative treatment.
