Natural HistoryDaSilva, Raizman: Ch 44: Lateral and Medial ElbowTendinopathy and Olecranon Bursitis, in ASSHTextbook of Hand and Upper Extremity Surgery, 2019 Multiple studies: 80-90% resolution over about 1 year Natural history really varies (MULTIPLE FACTORS)‒ Example: Physicians w/ LE showed they were less likely to use NSAIDs, misswork, or receive injections, and all but 2/72 resolved within 2 years19To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Diagnosis Standard physical exam Relevant to surgical decision-making: Pain in an uncommon location‒ Radial nerve involvement – RTS‒ Posterolateral / RC elbow joint Instability UN symptoms / weakness20To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Diagnosis Imaging Usually not indicated XR is often routinely done anyway Dynamic fluoroscopy to identify instability US / MRI will show pathology – usually not needed Can also identify additional pathology (joint / nerve) EMG if UN is involved21To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Treatment Options – Focus on Surgical Management22To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

“Refractory” epicondylitis Nobody offers surgery right off the bat How long to wait? Patient perspective: 3 months of no improvement is too long Most surgical studies: 6 months of no improvement is indication for OR Thus, the evidence that will be presented is for patients who “failed”non-operative treatment for at least 6 months23To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

ECRB Debridement – “Nirschl Procedure” Open debridement of the abnormal tissue in the ECRB origin is the classicsurgical technique 84% good-excellent results long-term 97% overall improved; 93% rate of return to sportImage from Green’s 6th edition24To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Debridement of ME Long-term results: 94%good/excellent Pain improvedfrom 9 to 225To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Debridement and repair (LE) 94% return to activity 95% reduction in pain26To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Debridement and repair (ME) The degenerated tendon is debrided Origin is repaired back to bone, often with the use of a suture anchor27To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Arthroscopic Treatment of LE Arthroscopic treatment: ability to identify/treat intra-articular pathology Debridement of ECRB28To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisTenotomy of ECRBHTA 2020

Arthroscopic Treatment Debridement of ECRB or Tenotomy ofECRB 283 patients 78% overall excellent results 8-10% failure rate No significant differences exceptfaster RTW in debridement29To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Arthroscopic Treatment of ME Small series (7 patients) Origin of the common flexor/pronator tendon debrided proximal to UCL30To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Arthroscopic Treatment of ME31To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Denervation (LE) Transection of branches of thePosterior cutaneous nerve of theforearm 30 elbows in 26 patients, min 2yr f-up 80% good-excellent results VAS: 7.9 1.9 4 patients w/ failure (work comp orRTS)32To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Which surgery is better? Is one type of surgery better than others? POP-QUIZ! What was the rate of good/excellent results % in the various treatmentoptions? Which was the best? In ortho, we teach residents 85%/15% is always a good guess Seems to be the case here: what does the evidence tell us?33To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

LE debridement: open vs scope 75 patients randomized 1 yr f-up No difference between thegroups Everyone got better “Notice the VAS and DASHscores at 12 mo – these are allsimilar across all studies”34To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

LE debridement: open vs scope Meta-analysis included 6 studies “There was no significant difference with regards to failure rate, functionaloutcome score, and complication rate”35To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

LE debridement: open vsscope vs percutaneous Systematic review included 6 studies Level 1 and 2 179 elbows total36To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Differences between surgical treatments? NONE Across multiple studies, there are no clinically important or significantdifferences in outcomes SOME LIMITATIONS IN THE DATA Some patients may benefit from one treatment over other‒ These differences will not be obvious in small studies‒ Challenge is to identify these patients37To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Placebo Surgery40To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

13 patients enrolled in each group Study stopped early due to prelim statistical analysis demonstrating a needfor 6500 patients per group to demonstrate a significant difference Surgery: Nirschl technique, debridement and drilling of the bone Placebo: Same incision, the skin was dissected down to the ECRB tendon tovisualize the abnormal tissue. This was NOT excised, and skin was closed. Follow-up 6mo and 2.5 years41To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

So is there ANY role for surgery? Possibly yes Are there any red flags?‒ Ulnar nerve neuritis / cubital tunnel syndrome Severe pain or “nerve pain” Symptoms of UN irritation Extension contracture of the elbow48To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Ulnar nerve neuritis / cubital tunnel syndrome 34yo F, 1.5 years of medial elbow pain, multiple MD opinions, therapy, severalsteroid injections, MRI w/ medial epicondylitis – presumed dx Can’t flex elbow beyond 90 degrees because of medial elbow pain NO numbness/tingling/weakness by report but 4/5 ADM strength on exam49To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Ulnar nerve neuritis / cubital tunnel syndrome Managed w/ UN decompression and submuscular transposition Allows for a concomitant debridement/repair, and lengthening offlexor/pronator origin52To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Careful and thorough evaluation Are there any red flags?‒ LUCL injury / instability‒ Clunking / giving way w/ weight bearing‒ Pain is more with elbow loading than with grip‒ More mechanical symptoms53To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Careful and thorough evaluation Are there any red flags?‒ LUCL injury / instability‒ 40yo M, over 1 year lateral elbow pain‒ Dx as epicondylitis, had steroid injection‒ While lifting weights, felt a pop, significantly worsened pain54To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Careful and thorough evaluation Are there any red flags?‒ LUCL injury / instability‒ MRI and fluoro exam in the office demonstrate ill-defined / avulsed LUCLand varus instability55To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

56To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Careful and thorough evaluation Are there any red flags?‒ LUCL injury / instability‒ Managed with LUCL reconstruction with allograft, and concomitantdebridement/repair of the ECRB origin57To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Careful and thorough evaluation Are there any red flags or additional important pathology?‒ Intra-articular pathology: for example, plica, loose bodies‒ Mechanical symptoms (clicks, etc)‒ May be related to elbow position / forearm rotation‒ Tenderness more on the joint line and less on the LE‒ Can often see on imaging58To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Careful and thorough evaluation Are there any red flags or additional important pathology?‒ Intra-articular pathology: for example, plica in posterolateral RC joint59To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Careful and thorough evaluation Are there any red flags or additional important pathology?‒ Treat the additional pathology Reassurance The “tear” is not a “structurally important” tear Pain is NOT a sign of serious of ongoing damage OK to exercise / work through the pain Bracing, exercises, TIME – eventually it gets better60To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Careful and thorough evaluation Reassurance Bracing, exercises, TIME – eventually it gets better Rarely get advanced imaging – only generates more questions about the “tear” Rarely surgery61To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

62To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

My Practice Surgery Rarely done‒ Unless there is additional pathology (nerve, ligament, joint) Open debridement and repair of tendon back to origin with an anchor Why? Most comparative studies focus on the debridement alone – perhaps repairis better (no real evidence) Repair just makes sense to me63To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Natural HistoryDaSilva, Raizman: Ch 44: Lateral and Medial ElbowTendinopathy and Olecranon Bursitis, in ASSHTextbook of Hand and Upper Extremity Surgery, 2019 Multiple studies: 80-90% resolution over about 1 year Doesn’t seem to be any different from any treatment available BUT, what about the patients that don’t improve?64To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020

Future Directions Identify those patients that won’t improve on their own Design studies including ONLY those patients‒ Harder because there are very few of them around‒ Difficult to predict‒ Challenging to convince patients to suffer for over 1 year It is possible that benefits of surgery will emerge in this group I suspect it may be the debridement repair type of operation65To Cut or Not to Cut: Current Evidence for Treatment for Lateral and Medial EpicondylitisHTA 2020
