Brief Summary

The appropriate treatment of labral lesions such as SLAP tears in patients undergoing RC tears repair is controversial. Most surgeons are reluctant to repair RC and SLAP tears simultaneously due to the high likelihood of prolonged postoperative immobilization, stiffness and poor clinical outcomes. The current standard care interventions include debridement, biceps tenotomy or tenodesis rather than surgical repair of SLAP tears. Simple debridement is a low cost and time-saving procedure that has the advantage of maintaining the anatomy of the long head of biceps (LHB), a muscle that acts as an active depressor of the head of the humerus in patients with RC tears. Biceps tenotomy is also low cost and time-saving; however, since the LHB is released from its attachment in the shoulder joint, the anatomy is not preserved and results in decreased strength and possible development of a 'Popeye' deformity. Biceps tenodesis has higher costs and time than the other two approaches, but has the advantage of preserving the LHB anatomy and power, and a lower possibility of developing complications. Finally, labral repair has the highest costs and associated surgical time and may lead to increase stiffness after surgery, particularly in patients over 45 years old.

Currently, the standard care of the surgeons involved in this study is to use either debridement or biceps tenodesis to address labral lesions in patients undergoing surgery for their RC tear. Based on the current evidence and current practice in our facility, we aim to compare the efficacy of tenodesis versus debridement in patients with combined RC tear, degenerative labrum (SLAP tears) and a normal biceps tendon.

Detailed Description

Rotator cuff (RC) tears are the most common source of shoulder pain, disability and discomfort. In fact, RC disease is the most common cause of shoulder pain seen by physicians. It has been estimated that as many as 40% of patients with shoulder pain may have a RC tear. Previous research has shown that 80% of these patients will experience pain, and 40% of patients will experience tear progression (tear becoming larger, more painful, multiple muscle involvement). Therefore, it is no surprise that a substantial proportion of individuals with RC tears do not receive adequate relief from non-operative treatments (physiotherapy, acupuncture, massage therapy, activity/work modification, cortisone injection), and require surgical repair.

Surgical repair has been challenging in this population, since frequently RC tears are associated with concomitant labral lesions such as SLAP (superior labral anterior-posterior) tears that may increase patients' symptoms. Miller and Savoie studied one hundred patients with full-thickness RC tears and determine that 74% had coexisting intra-articular abnormalities, and labral tears were the most common associated pathology. Gartsman et al reported that 60.5% of patients with full-thickness RC tears had coexisting intraarticular abnormalities, with 25 patients (12.5%) having major abnormalities that required surgery, changed postoperative rehabilitation or impacted the expected end result. Snyder et al. 8 reported that 40% of patients with SLAP lesions had associated full- or partial-thickness RC tears.

The appropriate treatment of labral lesions such as SLAP tears in patients undergoing RC tears repair is controversial. Most surgeons are reluctant to repair RC and SLAP tears simultaneously due to the high likelihood of prolonged postoperative immobilization, stiffness and poor clinical outcomes. Therefore, the current standard care interventions include debridement, biceps tenotomy or tenodesis rather than surgical repair of SLAP tears3. Recently, Oh et al. compared simple debridement, biceps tenotomy, and biceps tenodesis for the patients with concomitant RC tear and labral lesions. All concomitant treatments improved patients' symptoms. Simple biceps debridement had the lowest risk of patients developing a 'Popeye' deformity and preserved forearm supination strength. Biceps tenotomy appeared preferable for patients with definite groove tenderness while biceps tenodesis was indicated for patients with groove tenderness, but who wanted to preserve supination strength. However, this study was compromised by low follow-up (72%) within one year and unbalanced groups (i.e.one group had significantly more males). Abbot et al. determined that patients over the age of 45 years treated with arthroscopic RC repair and SLAP debridement had significantly better function, pain relief, and range of motion than those treated with RC repair and simultaneous SLAP repair. A systematic review in 2011 looked at the current evidence for effectiveness of interventions to treat RC tears, and they found limited evidence favoring debridement compared to anchor replacement and suture repair of Type II SLAP tear. Another systematic review in 2014 revised the published data on the surgical treatment of superior labral injuries in patients aged 40 years, including those with concomitant injuries to the RC and they stated that the cumulative evidence supports labral debridement or biceps tenotomy over labral repair when an associated RC injury is present.

The above studies are contradictory likely because studies were heterogeneous in terms of selection as well as assessment periods and outcome measurements performed. Therefore, the question about best practice to treat labral lesions in patients with concomitant RC tears remains unanswered.

Moreover, in previous studies, surgical time and costing with the different approaches were not considered. Simple debridement is a low cost and time-saving procedure that has the advantage of maintaining the anatomy of the long head of biceps (LHB), a muscle that acts as an active depressor of the head of the humerus in patients with RC tears. Biceps tenotomy is also low cost and time-saving; however, since the LHB is released from its attachment in the shoulder joint, the anatomy is not preserved and results in decreased strength and possible development of a 'Popeye' deformity. Biceps tenodesis has higher costs and time than the other two approaches, but has the advantage of preserving the LHB anatomy and power, and a lower possibility of developing complications. Finally, labral repair has the highest costs and associated surgical time and may lead to increase stiffness after surgery, particularly in patients over 45 years old.

Currently, the standard care of the surgeons involved in this study is to use either debridement or biceps tenodesis to address labral lesions in patients undergoing surgery for their RC tear. Annually, in the Edmonton region, as an estimate from all of the surgeons involved in this study, surgeons perform around 200 of each technique (debridement or biceps tenodesis). Based on the current evidence and current practice in our facility, we aim to compare the efficacy of tenodesis versus debridement in patients with combined RC tear, degenerative labrum (SLAP tears) and a normal biceps tendon.
