Supraspinatus repair and biceps tenodesis in competitive CrossFit athletes allow for a 100% of return to sport

Criteria, Timing, and Factors Associated With Return to Competitive Sport After Rotator Cuff Surgery

Rotator cuff pathology in competitive athletes is common and may produce chronic symptoms and joint disability, impairing sports participation and leading to premature retirement. Athletes are a high-functioning patient population with unique characteristics. Decision-making for return to sport is a complex and multifactorial process. Literature is sparse and does not provide precise guidelines to assist physicians to make the right decision. This review aimed to highlight factors affecting outcome, timing, and criteria for return to competitive sport after rotator cuff surgery to help physicians to clearly counsel athletes and make high-quality decisions for return to sport.

Return to Sport at Preinjury Level is Common After Surgical Treatment of SLAP Lesions: A Systematic Review and a Meta-analysis

BACKGROUND

Patients undergoing surgery for Superior-Labrum-anterior-to-posterior (SLAP) lesions are often worried about their return to sport performance. This systematic review determined the rate of return to sport and return to sport at the previous level (RTSP) after surgery for SLAP lesion.

MATERIALS AND METHODS

The PRISMA guidelines were followed. Meta-analysis of data through forest plot projections was conducted. Studies were divided and analyzed according to the type of interventions (isolated slap repair or SLAP repair with rotator cuff debridement and biceps tenodesis).

RESULTS

The mean overall rate of return to sport after the procedures was 90.6% and the mean overall rate of return to sport at the previous level after the procedures was 71.7%. RTSP rates of the whole population were 71% (95% CI: 60%-80%), 66% (95% CI: 49%-79%), and 78% (95% CI: 67%-87%) for isolated SLAP repair, SLAP repair with the rotator cuff debridement and biceps tenodesis, respectively. A lack of subgroup analysis for the specific performance demand or type of lesion related to the surgical technique used might induce a high risk of bias.

DISCUSSION

Return to sports at the previous level after surgically treated superior labrum anterior to posterior lesion is possible and highly frequent, with the highest rates of RTSP in patients treated with biceps tenodesis. More studies and better-designed trials are needed to enrich the evidence on indications of SLAP surgical treatment in relation to specific sports-level demand.

Return to Sport after Arthroscopic Rotator Cuff Repair of Full-Thickness Rotator Cuff Tears: A Systematic Review

OBJECTIVE

Perform a systematic literature review regarding return to sport (RTS) outcomes after arthroscopic rotator cuff repair (aRCR) for full-thickness rotator cuff tears (FTRCTs).

DATA SOURCES

Systematic review of all articles in PubMed, Medline, and Excerpta Medica Database (EMBASE) was conducted in April 2022 using a combination of keywords: "rotator cuff repair," "RCR," "complete," "full-thickness," "tear," "RCT," "injury," "shoulder," "arthroscopic," "return to sport," "RTS," "sport," "return to play," and "athlete." Cohorts were included from all articles reporting RTS after aRCR for FTRCTs. Studies that were non-English, failed to distinguish between partial and FTRCT outcomes, or treated FTRCTs by open RCR, mini-open RCR, debridement, or nonsurgical management were excluded. Abstracted data included study design, surgical techniques, concomitant procedures, demographics, FTRCT type and size, patient-reported outcomes, type of sport, competition level, time to return, and reasons for failing to RTS.

MAIN RESULTS

11 studies were reviewed, with inclusion of 463 patients (385 athletes; mean age 47.9). RTS varied considerably in rate and timing, with 50.0% to 100% of patients returning on average between 4.8 to 14 months. In addition, 31 patients returned to a higher level of sport, 107 returned to or near preinjury level, and 36 returned to a lower level of competition or failed to RTS entirely.

CONCLUSIONS

The ability for athletes to RTS after aRCR for FTRCTs is likely multifactorial, demonstrating high variability in return rates and time to RTS. Given the paucity of available literature, future studies are warranted to provide a more definitive consensus.

Computer-assisted surgery and patient-specific instrumentation improve the accuracy of tibial baseplate rotation in total knee arthroplasty compared to conventional instrumentation: a systematic review and meta-analysis

PURPOSE

To determine whether patient-specific instrumentation (PSI), computer-assisted surgery (CAS) or robot-assisted surgery (RAS) enable more accurate rotational alignment of the tibial baseplate in primary total knee arthroplasty (TKA) compared to conventional instrumentation, in terms of deviation from the planned target and the proportion of outliers from the target zone.

METHODS

The authors independently conducted three structured electronic literature searches using the PubMed, Embase®, and Cochrane Central Register of Controlled Trials databases from 2007 to 2020. Studies were included if they compared rotational alignment of the tibial baseplate during TKA using conventional instrumentation versus PSI, CAS, and/or RAS, and reported deviation from preoperatively planned rotational alignment of the tibial baseplate in terms of absolute angles and/or number of outliers. Methodological quality of eligible studies was assessed by two researchers according to the Downs and Black Quality Checklist for Health Care Intervention Studies.

RESULTS

Fifteen studies, that reported on 2925 knees, were eligible for this systematic review, of which 6 studies used PSI, and 9 used CAS. No studies were found for RAS. Of the studies that reported on angular deviation from preoperatively planned rotational alignment, most found smaller deviations using PSI (0.5° to 1.4°) compared to conventional instrumentation (1.0° to 1.6°). All studies that reported on proportions of outliers from a target zone (± 3°), found lower rates of outliers using PSI (0 to 22%) compared to conventional instrumentation (5 to 96%). Most studies reported smaller angular deviation from preoperatively planned rotational alignment using CAS (0.1° to 6.9°) compared to conventional instrumentation (1.1° to 7.8°). Of the studies that reported on proportions of outliers from a target zone (± 3°), most found fewer outliers using CAS (10 to 61%) compared to conventional instrumentation (17 to 78%).

CONCLUSION

This systematic review and meta-analysis revealed that both CAS and PSI can improve the accuracy of rotational alignment of the tibial baseplate by decreasing angular deviation from the preoperatively planned target and reducing the proportion of outliers from the target zone. The clinical relevance is that PSI and CAS can improve alignment, though the thresholds necessary to grant better outcomes and survival remain unclear.

Upper Extremity Injuries in CrossFit Athletes-a Review of the Current Literature

PURPOSE OF REVIEW

Cross-discipline fitness, or CrossFit, has exploded in popularity during the last two decades. During this time, there have been a high volume of patients presenting to clinicians with a wide range of associated injuries. Given the high intensity, high repetition, and competitive nature of CrossFit training and competition, athletes are vulnerable to injury, particularly upper extremity injury. The rate of injury to the shoulder, elbow, and wrist in CrossFit is higher when compared to traditional weight-training and more comparable to elite-level gymnastics and Olympic-style lifting. Due to the growing popularity of CrossFit-style exercise and the relatively high rate of injury among its participants, clinicians are likely to encounter these athletes. The purpose of this review is to familiarize clinicians with CrossFit and the associated injuries they will likely encounter.

RECENT FINDINGS

The medical literature focusing on CrossFit has demonstrated exponential growth, with the first article published in 2012 and 59 articles published in 2020. Although the body of literature is growing, there are no high-level studies focusing on CrossFit. The literature mainly consists of level IV and V studies, primarily consisting of case reports and case series. Recent studies have proven that CrossFit athletes are vulnerable to high rates of upper extremity injury and a few studies have identified risk factors for injury. Future high-level research is required to study modifiable risk factors, diagnostic criteria, and treatment options for these high-risk athletes in order to improve the safety of their sport. The CrossFit body of research is limited to level IV and V studies; however, the literature is clear, CrossFit athletes face a high rate of upper extremity injury. For this reason, clinicians must be familiar with CrossFit and its associated pathology. The goal of this review is to familiarize clinicians with CrossFit and the associated pathologies they will likely encounter.

The Lark Loop Used for Proximal Biceps Tenodesis: An All-Arthroscopic Technique

Long head of the biceps tendinopathy is a common shoulder problem that is difficult to diagnose and treat. Biceps tenodesis is an effective surgical approach target for long head of the biceps tendon lesions. This article describes an all-arthroscopic proximal biceps tenodesis technique. This technique uses a high-strength suture to construct a tear-resistant loop; fixation is achieved with a suture anchor at the proximal aspect of the intertubercular groove or the greater tuberosity. This tenodesis fixation is simple, with no neurovascular injury or humeral fracture risk. In addition, our technique is cost-effective, with no need for specialty sutures.

Criteria for Return-to-Play (RTP) after Rotator Cuff Surgery: A Systematic Review of Literature

This systematic review of the literature aimed to highlight which criteria are described in the literature to define when a patient, after rotator cuff repair (RCR), is ready for return-to-play (RTP), which includes return to unrestricted activities, return to work, leisure, and sport activities. An online systematic search on the US National Library of Medicine (PubMed/MEDLINE), SCOPUS, Web of Science (WOS), and the Cochrane Database of Systematic Reviews, was performed with no data limit until December 2021. A total of 24 studies that reported at least one criterion after RCR were included. Nine criteria were identified and among these, the most reported criterion was the time from surgery, which was used by 78% of the studies; time from surgery was used as the only criterion by 54% of the studies, and in combination with other criteria, in 24% of the studies. Strength and ROM were the most reported criteria after time (25%). These results are in line with a previous systematic review that aimed to identify RTP criteria after surgical shoulder stabilization and with a recent scoping review that investigated RTP criteria among athletes after RCR and anterior shoulder stabilization. Compared to this latest scoping review, our study adds the methodological strength of being conducted according to the Prisma guidelines; furthermore, our study included both athletes and non-athletes to provide a comprehensive view of the criteria used after RCR; moreover, ten additional recent manuscripts were examined with respect to the scoping review.

Lateral tibial intercondylar eminence is a reliable reference for alignment correction in high tibial osteotomy

PURPOSE

The purpose of the study is to determine whether the lateral tibial intercondylar eminence (LTIE) is a reliable reference for alignment correction in high tibial osteotomy (HTO).

METHODS

A total of 1954 consecutive standing whole-leg radiography (WLR) examinations of 1373 adult patients with knee osteoarthritis between 2012 and 2019 were reviewed retrospectively; 145 patients were included, 53 males and 92 females, with a mean age of 63.3 years. Virtual simulation of HTO was performed to measure weight-bearing line (WBL) percentages and hip-knee-ankle (HKA) angles when the WBL passed through the Fujisawa, top, bottom, upper 1/3, and middle points of the lateral slope of the LTIE, and the positional relationship between the Fujisawa point and the lateral slope of the LTIE was determined.

RESULTS

When the WBL passed through the top, bottom, upper 1/3, and middle points of the lateral slope of the LTIE, the mean WBL percentages were 57.7% ± 2.1%, 74.6% ± 3.3%, 63.4% ± 2.1%, and 66.2% ± 2.3%, respectively, and the mean HKA angles were 182.1° ± 0.5°, 185.9° ± 0.8°, 183.3° ± 0.5°, and 184.0° ± 0.5°, respectively. When the WBL passed through the Fujisawa point, it was passing through 28.6% ± 12.7% of the width of the lateral slope (the top and bottom points were defined as 0% and 100%, respectively). When the WBL passed through the middle and upper 1/3 points of the lateral slope of the LTIE, the majority of cases (96.1%-100%) were within the limits of acceptability, as defined by the widely accepted standard of a postoperative HKA angle ranging from 183° to 186°.

CONCLUSION

The upper 1/3 and middle points of the lateral slope of the LTIE are reliable references for guiding the alignment correction in HTO. In clinical application, if 62%-66% of the postoperative WBL percentage is the acceptable target range, the upper 1/3 point of the lateral slope of the LTIE may be a better alternative than the midpoint. If the postoperative HKA angle between 183° and 186° is acceptable, the midpoint of the lateral slope of the LTIE may be better than the upper 1/3 point. These findings are crucial for the accuracy of the traditional intraoperative alignment assessment techniques.
