Systematic review: laparoscopic treatment of long-standing groin pain in athletes

Athletes treated for inguinal-related groin pain by endoscopic totally extraperitoneal (TEP) repair: long-term benefits of a prospective cohort

PURPOSE

Inguinal-related groin pain (IRGP) in athletes is a multifactorial condition, posing a therapeutic challenge. If conservative treatment fails, totally extraperitoneal (TEP) repair is effective in pain relief. Because there are only few long-term follow-up results available, this study was designed to evaluate effectiveness of TEP repair in IRGP-patients years after the initial procedure.

METHODS

Patients enrolled in the original, prospective cohort study (TEP-ID-study) were subjected to two telephone questionnaires. The TEP-ID-study demonstrated favorable outcomes after TEP repair for IRGP-patients after a median follow-up of 19 months. The questionnaires in the current study assessed different aspects, including, but not limited to pain, recurrence, new groin-related symptoms and physical functioning measured by the Copenhagen Hip and Groin Outcome Score (HAGOS). The primary outcome was pain during exercise on the numeric rating scale (NRS) at very long-term follow-up.

RESULTS

Out of 32 male participants in the TEP-ID-study, 28 patients (88%) were available with a median follow-up of 83 months (range: 69-95). Seventy-five percent of athletes were pain free during exercise (p < 0.001). At 83 months follow-up, a median NRS of 0 was observed during exercise (IQR 0-2), which was significantly lower compared to earlier scores (p <0.01). Ten patients (36%) mentioned subjective recurrence of complaints, however, physical functioning improved on all HAGOS subscales (p <0.05).

CONCLUSION

This study demonstrates the safety and effectivity of TEP repair in a prospective cohort of IRGP-athletes, for whom conservative treatment had failed, with a follow-up period of over 80 months.

Surgical Outcomes of Inguinal-, Pubic-, and Adductor-Related Chronic Pain in Athletes: A Systematic Review Based on Surgical Technique

Background:

Controversies remain regarding the surgical treatment of inguinal-, pubic-, and adductor-related chronic groin pain (CGP) in athletes.

Purpose:

To investigate the outcomes of surgery for CGP in athletes based on surgical technique and anatomic area addressed.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

The PubMed and Embase databases were searched for articles reporting surgical treatment of inguinal-, pubic-, or adductor-related CGP in athletes. Inclusion criteria were level 1 to 4 evidence, mean patient age >15 years, and results presented as return-to-sport, pain, or functional outcomes. Quality assessment was performed with the CONSORT (Consolidated Standards of Reporting Trials) statement or MINORS (Methodological Index for Non-randomized Studies) criteria. Techniques were grouped as inguinal, adductor origin, pubic symphysis, combined inguinal and adductor, combined pubic symphysis and adductor, or mixed.

Results:

Overall, 47 studies published between 1991 and 2020 were included. There were 2737 patients (94% male) with a mean age at surgery of 27.8 years (range, 12-65 years). The mean duration of symptoms was 13.1 months (range, 0.3-144 months). The most frequent sport involved was soccer (71%), followed by rugby (7%), Australian football (5%), and ice hockey (4%). Of the 47 articles reviewed, 44 were classified as level 4 evidence, 1 study was classified as level 3, and 2 randomized controlled trials were classified as level 1b. The quality of the observational studies improved modestly with time, with a mean MINORS score of 6 for articles published between 1991 and 2000, 6.53 for articles published from 2001 to 2010, and 6.9 for articles published from 2011 to 2020. Return to play at preinjury or higher level was observed in 92% (95% CI, 88%-95%) of the athletes after surgery to the inguinal area, 75% (95% CI, 57%-89%) after surgery to the adductor origin, 84% (95% CI, 47%-100%) after surgery to the pubic symphysis, and 89% (95% CI, 70%-99%) after combined surgery in the inguinal and adductor origin.

Conclusion:

Return to play at preinjury or higher level was more likely after surgery for inguinal-related CGP (92%) versus adductor-related CGP (75%). However, the majority of studies reviewed were methodologically of low quality owing to the lack of comparison groups.

Totally extra-peritoneal repair versus trans-abdominal pre-peritoneal repair for the laparoscopic surgical management of sportsman's hernia: A systematic review and meta-analysis

BACKGROUND

Open and laparoscopic modalities are employed for treatment of sportsman's hernia with totally extra-peritoneal (TEP) and trans-abdominal pre-peritoneal (TAPP) laparoscopic approaches both currently being utilised. At present, neither subtype has demonstrated a beneficial superiority for sportsman's hernia repair, as concluded in the most recent systematic review comparing the outcomes of each technique. The aim of this review was to evaluate current evidence to ascertain whether there was a difference in laparoscopic techniques following sportsman's hernia repair.

METHODS

A systematic literature search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards. Databases searched included PubMed, Scopus and Web of Science to identify all randomised controlled trials (RCTs) and observational studies Risk of bias was assessed using the Cochrane risk of bias tool and Newcastle-Ottawa scale for RCTs and observational studies, respectively.The assessed outcomes included median time to return to sporting activity, complications and the degree of postoperative pain reduction within three months. Random effects model was used to calculate pooled proportion data where feasible. Subgroup analyses were also performed.

RESULTS

28 studies were identified including 2 RCTs and 26 observational studies. No significant differences were observed between techniques in the primary or secondary outcomes. Significant heterogeneity was observed in all outcomes. This was more pronounced for return to sporting activity meaning that meta-analysis was not feasible in this domain. Median time to return to sporting activity was 28 days for both techniques.

CONCLUSIONS

There is no observed difference in the primary and secondary outcomes in either technique. An RCT comparing TEP and TAPP repair is needed to provide definitive data on this matter.

Totally extraperitoneal repair for the 'sportsman's groin' via 'the Manchester Groin Repair': a comparison of elite versus amateur athletes

BACKGROUND

Surgery has a recognised role in the treatment of 'sportsman's groin'. This study hypothesises that elite athletes have a superior advantage in both pre- and post-op rehabilitation and therefore will present and resume sporting activities quicker.

METHODS

A retrospective analysis on a secure database of athletes presenting with groin pain that underwent surgery for 'inguinal disruption'. All data were explored via appropriate descriptive statistics and comparisons made between elite and amateur athletes.

RESULTS

All patients were male (n = 144). The median age 33 years (range 14-72). The median return to sporting activity was 4.5 weeks (range 2.0-16.0) with one amateur athlete being unable to return to sporting activity. Using the mean of both sides, a comparison of VAS pain scores at pre-operative and 1 month post-operative time points showed a significant reduction (p < 0.001). Comparing 'elite' versus 'amateur' athletes, significant differences were seen in patient age (median 26 vs 40 years; p < 0.001), lead time to clinic presentation (median 62.0 vs 111.5 days; p = 0.004), and time to return to sporting activity (4 vs 5 weeks; p = 0.019). Additional MRI findings within the groin girdle were found in 89 patients (66.4%) and 34 patients (23.6%) had an MRI finding within the adductor tendon.

CONCLUSION

The Manchester Groin Rrepair is an effective surgical management for 'inguinal disruption'. Elite athletes present quicker and return to sport sooner. Given the prevalence of other findings, a multidisciplinary approach to the 'sportsman's groin' is required.

Total extraperitoneal laparoscopic inguinal hernia repair with adductor tenotomy: a 10-year experience in the treatment of athletic pubalgia

BACKGROUND

Athletic pubalgia, commonly referred to as a "sports hernia," is a disease process characterized by groin pain produced by physical exertion often occurring in patients whose athletic activities require them to make rapid changes in direction. The groin pain is due to the traction-countertraction relationship between the adductor muscles and the weaker abdominal muscles. Hence, a few studies have shown inguinal hernia repair with adductor tenotomy to be an effective treatment for this pathology (Brody in Hernia 21:139-147, 2016, https://doi.org/10.1007/s10029-016-1520-8 ; Rossidis et al. in Surg Endosc 29:381-386, 2015, https://doi.org/10.1007/s00464-0143679-3 ). However, these studies are small and few in quantity but have demonstrated promising results. Thus, we sought to further study this combined surgical approach as a treatment for this multifactorial disease to improve our understanding and outcomes.

METHODS

With IRB approval, we retrospectively reviewed the charts of all patients who underwent adductor tenotomy and inguinal hernia repair for the treatment of athletic pubalgia at Mount Sinai Medical Center, Miami Beach FL. Parameters gathered included basic demographics, past medical and surgical history, athletic activity, length of surgery, length of time between surgery and follow-up, intraoperative and postoperative complications, and time to return to athletic activities.

RESULTS

A total of 93 patients underwent inguinal hernia repair with adductor tenotomy. These procedures were all performed by a single surgeon at two academic institutions. The average age of patients was 23.4 years. Athletic activities reported by the patients were as follows: American football (n = 36), soccer (n = 18), triathlon (n  = 11), track and field (n = 8), and baseball (n = 5). Less-represented activities included swimming (n = 3), tennis (n = 2), lacrosse (n = 1), golf (n = 1), and other (n = 8). Mean operative time was 72.4 min. Most patients were found to return to athletic activity in 28 days following a standardized physical therapy regimen (92.5%). Postoperative complications included recurrence of pain/symptoms (7.5%, n = 7), urinary retention (2.2%, n = 2), pain along the adductor magnus/brevis muscle group with more extraneous activity (1.1%,  n = 1), and adductor brevis hematoma 3 months following surgery and rehabilitation (1.1%, n = 1). Of the patients with recurrent pain, 2/7 reported contralateral pain.

CONCLUSIONS

Total extraperitoneal laparoscopic inguinal hernia repair with adductor tenotomy appears to be a relatively quick and safe procedure with few postoperative complications. The majority of treated athletes are able to return to full athletic activities within 28 days of operation. While a return of symptoms has been seen in some patients, it is frequently observed on the contralateral side.

[Diagnostic algorithm "FAI and sports hernia" : Results of the consensus meeting for groin pain in athletes]

As a result of the complexity and diversity of diseases in the region of the groin, differentiation of the various soft-tissue and bone pathologies remains a challenge for differential diagnosis in routine clinical practice. In the case of athletes with pain localized in the area of the groin, femoroacetabular impingement (FAI) and athlete's groin must be considered as important causes of the groin pain, whereby the common occurrence of double pathologies further complicates diagnosis. Despite the importance of groin pain and its differential diagnoses in everyday clinical practice, there has been a lack of recognized recommendations for diagnostic procedure to date. To this end, a consensus meeting was held in February 2017, in which a group composed equally of groin and hip surgeons took part. With the formulation of recommendations and the establishment of a practicable diagnostic path, colleagues that are involved in treating such patients should be sensitized to this issue and the quality of the diagnosis of groin pain improved in routine clinical practice.

Laparoscopic Approach to Inguinal Disruption in Athletes: a Retrospective 13-Year Analysis of 198 Patients in a Single-Surgeon Setting

Background

Inguinal disruption (ID) is a condition of chronic groin pain affecting mainly athletes. ID cannot be defined as a true hernia. Pathogenesis is multifactorial due to repetitive and excessive forces applied to the inguino-pelvic region. Examination reveals tenderness to palpation of the inguinal region. Differential diagnosis is challenging; imaging is helpful for excluding other pathologies. Surgery is the treatment of choice when conservative treatment fails. Primary aim of the study was to evaluate the time to return to full sport activity after transabdominal preperitoneal patch plasty (TAPP) technique in ID. Secondary aim was to evaluate the postoperative complication rate both in the immediate post-operative time and in 1 year follow-up and to verify the relapse rate after surgery. In this study, we consider time to return to full sport activity as the time needed to return to pre-injury sport activity.

Results

A retrospective study is reported by evaluating 198 cases of ID from a single surgeon experience. All patients failed a previous conservative treatment. All cases were treated with the TAPP approach. Time to return to full sport activity was 4 weeks for 94.4% of patients, with a total of 98.5% of active patients at 9 months. Post-operative inguinal pain was the main complication (9.1%). On 13 years follow-up, we report a recurrence rate of 2.5%.

Conclusions

Current management algorithm for ID, in professional athletes, supports the role of surgery after at least 2 months of conservative treatment. Recently, the role of surgery has been highlighted for a definitive treatment and a faster full recovery to sport activity, especially for elite professional athletes. In our opinion, laparoscopic surgery is the mainstay for non-responsive ID treatment. We present a long-term retrospective evaluation of a wide cohort of professional athletes diagnosed and treated in a systematic way.

Randomized clinical trial of open suture repair versus totally extraperitoneal repair for treatment of sportsman's hernia

Background

Sportsman's hernia/athletic pubalgia is a recognized cause of chronic groin pain in athletes. Both open and laparoscopic surgical repairs have been described for treatment, but there are no comparative studies. The hypothesis here was that relief of pain would be achieved earlier in patients treated with open minimal suture repair than totally extraperitoneal repair.

Methods

A randomized multicentre trial in four European countries was conducted to compare open minimal suture repair with totally extraperitoneal repair. The primary endpoint was complete relief of pain (visual analogue scale (VAS) score 20 or less on a scale from 0 to 100 mm) at 1 month. Secondary endpoints included complications, time to return to sporting activity, and number of patients returning to sport within 1 year.

Results

A total of 65 athletes (92 per cent men) with a median age of 29 years were enrolled (31 open repair, 34 totally extraperitoneal repair). By 4 weeks after surgery, median preoperative VAS scores had dropped from 70–80 to 10–20 in both groups (P &lt; 0·001). Relief of pain (VAS score 20 or less) during sports activity 4 weeks after surgery was achieved in 14 of 31 patients after open repair and 24 of 34 after totally extraperitoneal repair (P = 0·047). Return to full sporting activity was achieved by 16 and 18 patients respectively after 1 month (P = 0·992), and by 25 versus 31 after 3 months (P = 0·408).

Conclusion

Totally extraperitoneal repair was less painful than open repair in the first month, but otherwise both procedures were similarly effective in treating chronic pain due to sportsman's hernia. Registration number: NCT02297711 ( http://www.clinical.trials.gov).

Long-standing groin pain in contact sports: a prospective case-control and MRI study

Objectives

We aimed to prospectively evaluate the prevalence of long-standing groin pain and related MRI findings in contact sports.

Methods

This case–control study followed three male elite-level soccer, ice-hockey and bandy teams (102 players) for 2 years. All athletes with long-standing groin pain lasting >30 days and age-matched controls (1:3) from the same teams were examined clinically, using pelvic MRI and Hip and Groin Outcome Scores (HAGOS). Primary outcome measures were annual prevalence of groin pain and underlying MRI findings.

Results

The annual prevalence of chronic groin pain was 7.5%. Training characteristics and pain scores of athletes were similar in all teams. On MRI, there was no significant difference in the percentage of pubic bone marrow oedema (p = 0.80) between symptomatic players (8/15; 53%) versus controls (20/43; 47%), but adductor tendinopathy and degenerative changes at the pubic symphysis were twice more common among players with pain. Rectus muscle or iliopsoas pathology were seldom observed. Lower HAGOS subscales (p < 0.01) were recorded in players who experienced groin pain compared with the controls.

Conclusion

Long-standing groin pain was observed annually in 1 of 14 athletes in contact sports. Abnormalities in the pubic symphysis were common MRI findings in both symptomatic and asymptomatic players.

A qualitative literature review exploring the role of the inguinal ligament in the context of inguinal disruption management

Purpose

Groin injury, sportsman’s groin and inguinal disruption (ID) refer to a diffuse chronic groin pain syndrome that has significant impact on athletes and is often unresponsive to conservative management. The ID aetiology is poorly understood but may involve weakness of the inguinal ligament attachments or the posterior inguinal canal wall or the tendons of adductor longus and rectus abdominis. We discuss the literature in which the inguinal ligament was directly targeted for ID management in athletic populations. Secondarily, we discuss the anatomical reclassification of the inguinal ligament to a tendon based on the above information.

Methods

This was a qualitative review of the published literature, in English, from January 2007 to February 2017.

Results

Five research papers, including 264 patients, were appraised. In patients with ID, tears were identified in the inguinal ligament, and to relieve pain, the surgical treatment of the ligament by tenotomy was shown to be beneficial. Techniques such as radiofrequency denervation involving the inguinal ligament and ilioinguinal nerve were also shown to relieve symptoms in athletes.

Conclusions

This qualitative review has specifically focused on the literature directly targeting the inguinal ligament in ID which is a relatively unexplored management approach. When treated as a tendon, the inguinal ligament appears to be an appropriate ID therapeutic target. Integrated studies and randomised clinical trials will promote a better understanding of the role of the inguinal ligament and its tendinous properties in ID and provide a foundation for evidence-based management of chronic groin pain in athletes.

Athletic Pubalgia in Females: Predictive Value of MRI in Outcomes of Endoscopic Surgery

Background:

Athletic pubalgia is typically associated with male athletes participating in contact sports and less frequently with females. Endoscopic surgery may fully treat the patient with athletic pubalgia.

Purpose:

To perform an outcomes analysis of magnetic resonance imaging (MRI) and endoscopic surgery in female patients with athletic pubalgia.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Fifteen physically active female patients (mean age, 37 years) with athletic pubalgia were treated surgically via placement of total extraperitoneal endoscopic polypropylene mesh behind the injured groin area. The presence of preoperative bone marrow edema (BME) at the pubic symphysis seen on MRI was graded from 0 to 3 and correlated with pain scores after surgery. The outcome measures were pre- and postoperative pain scores and recovery to daily activity between 1 and 12 months after surgery. Results were compared with previously published scores from male athletes (n = 30).

Results:

With the exception of lower body mass index, the females with (n = 8) and without (n = 7) pubic BME had similar patient characteristics to the corresponding males. Mean inguinal pain scores (0-10) before surgical treatment were greater in females than males (during exercise, 7.8 ± 1.1 vs 6.9 ± 1.1; P = .0131). One month after surgery, mean pain scores for females were still greater compared with males (2.9 ± 1.7 vs 1.3 ± 1.6; P = .0034). Compared with female athletes with normal MRI, pubic BME was related to increased mean preoperative pain scores (8.13 ± 0.99 vs 6.43 ± 1.2; P = .0122). After 1 year, surgical outcomes were excellent or good in 47% of women.

Conclusion:

Endoscopic surgery was helpful in half of the females with athletic pubalgia in this study. The presence of pubic BME may predict slightly prolonged recovery from surgery.
