Athletic Pubalgia (Core Muscle Injury)

Groin pain is common with approximately 15% (range 5-23%) of all sports injuries result in groin pain (Litwin et al, 2011; Zoga et al, 2011).

WHAT IS ATHLETIC PUBALGIA?

• Athletic pubalgia is an overuse injury due to chronic wear from repetitive trauma or stress resulting in injury to the pelvic joints or
  tendons (Jose et al, 2014).

• Athletic pubalgia has been known by various terms over the years, including sports hernia, core muscle injury, adductor strain, osteitis pubis, "sportsman's hernia," or inguinal disruption (Heijboer et al, 2022). Despite the historical term ‘sports hernia’ being used, athletic pubalgia does
  not cause a visible bulge in the groin, as there is no true hernia as seen with the more common inguinal hernia.
  

• In the majority of cases, the tendons of the hip adductor muscle group and/or rectus abdominis are injured (Meyers et al, 2012).
• If the pelvic joint between your pubic bones (pubic symphysis) is inflammed then this is called osteitis pubis and results in groin and lower abdomen pain (Dirkx et al, 2023).
  

WHAT ARE THE SYMPTOMS?

• Patients typically experience pain in the groin and/or lower abdominal wall. Some patients may experience pain that radiates toward the perineum or inner thigh.
  

• Pain can be exacerbated by athletic activity such as kicking, cutting, or sprinting, and pain typically improves with rest.

TRADITIONAL TREATMENTS

Conservative Management

• Management of athletic pubalgia depends on pain and severity, but initial treatment often consistts of rest, oral nonsteroidal anti-inflammatory drugs (NSAIDs), and physical therapy (Jensen et al, 2014).
  

Steroid Injections

• Depending on location of injury, steroid injections into the pubic symphysis or adductor tendons can be coupled with therapy (Jose et al, 2014; Schilders et al, 2007).

Surgical Intervention

• In recalcitrant cases that do not respond to conservative treatment, surgical management maybe necessary (Gill et al, 2020; Meyers et al, 2000). One study reported a mean return to sport as 112 days (range, 53–223 days), and the mean return was significantly shorter in isolated abdominal wall injuries 91.1 days (range, 69–125 days) when compared to athletes with adductor or dual tendon involvement 132.5 days (range, 88–223 days) (Kajetanek et al, 2018).
  

ARE THERE ALTERNATIVES TO SURGERY?

In cases that fail conservative management, case reports and case series have examined platelet rich plasma and prolotherapy for core muscle injuries (learn more here).

Platelet Rich Plasma (PRP) Injections

PRP concentrates a patients own platelets from their blood to concentrate healing factors that play a central role in healing (learn more about PRP here)

• In case reports, PRP has been used in the treatment of core muscle injuries (Kraeutler et al, 2021; Scholeten et al, 2015; Park et al, 2020; Singh et al, 2010; St-Onge et al, 2015).
  

• In one report of a 20-year-old Division I collegiate lacross player, PRP was used to treatment athletic pubalgia symptoms (distal rectus abdominis tendinopathy) with an ultrasound-guided needle tenotomy and platelet-rich plasma (PRP) injection. In this cas , the patient returned to pain-free play at his previous level of intensity after the injection (Scholeten et al, 2015).
• In another case report of a 28-year-old soccer player, a complete adductor longus tendon tear was successfully treated with 2 PRP injections and returned to soccer without symptoms (Singh et al, 2010).
• In a case report of a 31-year old professional hockey player, 2 PRP injections successfully treated a tear in the rectus abdominis, rectus sheath and a portion of the conjoint tendon (St-Onge et al, 2015).
  
• In a case report we published, a case of isolated osteitis pubis without overlapping rectus abdominis or adductor tendon involvement was successfully treated with an ultrasound-guided PRP injection of the pubic symphysis fibrocartilage (Park et al, 2020).
  

Prolotherapy Injections

• In a series of 24 elite soccer and ruby players with chronic groin pain from osteitis pubis and/or adductor tendinopathy, monthly prolotherapy injections were administered and 22 of the 24 players returned to sport without pain (Topol et al, 2005).

PRP versus Prolotherapy Injections

• In a retrospective cohort study out of Turkey, 15 elite soccer players with groin pain that failed conservative management were treated with either 3 weekly dextrose prolotherapy injections or a PRP injection. Patient had the same rehabilitation protocol and were allowed to return to sport 28-days after the injections, and both groups demonstrated less pain at both the 1- and 6-month follow-up. At 6-months the PRP group had less pain, but this was not statistically significant (Ozkan et al, 2020).
