RESUMO
BACKGROUND: Osteochondritis dissecans (OCD) of the humeral capitellum is a rare and challenging condition to treat. Several surgical options exist, but in the last few years, the pendulum has swung from debridement and microfracture to restoration of the articular surface. Osteochondral autografts from the rib and knee have been described, but donor-site morbidity is a concern. PURPOSE: To expand the results of fresh osteochondral allograft transplantation (FOCAT) in a previously published report with inclusion of additional patients and a longer follow-up period. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: After institutional review board approval, the charts of patients who underwent FOCAT for OCD of the capitellum between 2006 and 2022 by a single surgeon were reviewed. The majority of cases (94%) had unstable lesions (Minami grades 2 and 3). A trial of nonoperative treatment had failed in all. All patients underwent diagnostic arthroscopy, followed by a mini-open, ligament-sparing approach with grafting using commercially available guides and instruments. RESULTS: A total of 35 patients were identified, of whom 25 were male. The mean age was 16 ± 3.9 years (range, 11-32 years). There were 24 baseball players (19 pitchers and 5 position players), 5 gymnasts, 3 cheerleaders/tumblers, 1 tennis player, 1 student (who did not participate in athletics), and 1 patient with avascular necrosis from chemotherapy. Eighteen patients had a mean flexion contracture of 14.1°± 11.9°. A single osteochondral allograft plug was used in 23 patients (mean diameter, 11.3 ± 2.8 mm), and 12 patients required 2 plugs (Mastercard technique). The mean follow-up was 92.6 ± 54.5 months (range, 24-204 months). There was significant improvement in Oxford (from 25.5 ± 4.9 to 46.7 ± 3.5; P < .00001) and visual analog scale for pain (from 7.5 ± 2 to 0.3 ± 1.0; P < .0001) scores. The mean Single Assessment Numeric Evaluation score at the time of follow-up was 90.6 ± 10.8 (range, 60-100). In overhead athletes, there was significant improvement in the Kerlan-Jobe Orthopaedic Clinic score (from 40.8 ± 11.8 to 90.6 ± 10.8; P < .00001). A postoperative magnetic resonance imaging scan was obtained in 16 (46%) patients at a mean of 32.6 months. In all cases, the graft was incorporated. All overhead athletes were able to return to their sport and perform at the same level or higher for >2 years. Two elbows required a subsequent arthroscopy for loose-body removal; otherwise, there were no other complications. CONCLUSION: FOCAT is an excellent option for treating OCD lesions of the humeral capitellum. Excellent outcomes and high return-to-sport rates were observed, with midterm follow-up showing no graft failures. FOCAT eliminates donor-site morbidity.

BACKGROUND: Bone marrow stimulation (BMS) has been proposed to augment healing at the time of arthroscopic rotator cuff repair (ARCR) by creating several bone marrow vents in the footprint of the rotator cuff, allowing mesenchymal stem cells, platelets, and growth factors to cover the area as a "crimson duvet." PURPOSE: To perform a meta-analysis of randomized controlled trials (RCTs) to compare the outcomes after BMS and a control for those undergoing ARCR. STUDY DESIGN: Meta-analysis; Level of evidence, 1. METHODS: A literature search of 3 databases was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RCTs comparing BMS and a control for ARCR were included. Clinical outcomes were compared, and a P value <.05 was considered to be statistically significant. RESULTS: A total of 7 RCTs with 576 patients were included. Overall, 18.8% of patients treated with BMS and 21.0% of patients treated with a control had a retear (I2 = 43%; P = .61). With BMS, the mean Constant score was 88.2, and with the control, the mean Constant score was 86.7 (P = .12). Additionally, there was no significant difference in the American Shoulder and Elbow Surgeons score (94.3 vs 93.2, respectively; P = .31) or visual analog scale score (0.9 vs 0.9, respectively; P = .89). CONCLUSION: The level 1 evidence in the literature did not support BMS as a modality to improve retear rates or clinical outcomes after ARCR.
RESUMO
PURPOSE: To perform a meta-analysis of randomized controlled trials (RCTs) to compare the outcomes of arthroscopic rotator cuff repair (ARCR) with and without acellular collagen matrix patch (ACMP) augmentation. METHODS: A literature search of 3 databases was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RCTs comparing ACMP augmentation and a control for ARCR were included. Clinical outcomes were compared using Revman, and a P value < .05 was considered to be statistically significant. RESULTS: Five RCTs with 307 patients were included. Overall, 11% of patients treated with ACMP augmentation and 34% of patients in the control group had a re-tear (P = .0006). The mean Constant score was 90.1 with ACMP augmentation, and 87.3 in controls (P = .02). Additionally, there was a significant higher American Shoulder and Elbow Surgeons score with ACMP augmentation (87.7 vs 82.1, P = .01). CONCLUSIONS: The RCTs in the literature support the use of ACMP augment as a modality to reduce re-tear rates and improve outcomes after ARCR. LEVEL OF EVIDENCE: Level II, Meta-Analysis of Level II Studies meta-analysis of Level II studies.

Anterior glenohumeral instability with an irreparable subscapularis tear is a challenging problem for the orthopedic shoulder surgeon. Current techniques, including tendon transfers, yield inconsistent results with high rates of recurrent instability. Acellular dermal allografting has been used in young patients with massive superior rotator cuff tears with early success, but acellular dermal allografting is comparatively unstudied in anterior deficiency. We present two cases of anterior capsular reconstruction with an acellular dermal allograft in patients ages 66 and 58 years with irreparable subscapularis tendon tears. Follow-up for both patients exceeded 4 years, with forward flexion >140°, external rotation exceeding 60°, a Single Assessment Numeric Evaluation score >90 points, a visual analog scale score of 0 points, and an American Shoulder and Elbow Score of 98 points. In conclusion, acellular dermal allografting can be used to reconstruct the anterior capsule in patients with massive irreparable subscapularis tears, similar to its use in superior capsular reconstruction in patients with massive posterosuperior rotator cuff tears.
RESUMO
We present two cases of symptomatic chronic long head of the biceps tendon (LHBT) ruptures treated with reconstruction of the tendon with an allograft due to native tendon shortening in one case and complete native tendon loss in the other. A gracilis allograft was Pulver-Taft weaved through the biceps muscle belly to reconstruct the LHBT and provide sufficient working length to perform a subpectoral tenodesis. In cases of chronic, symptomatic LHBT rupture with a shortened or absent tendon, a gracilis allograft can be used to reconstruct the biceps tendon and to perform a subpectoral tenodesis, providing symptom relief and reversing a Popeye muscle.
RESUMO
BACKGROUND: Radial head arthroplasty (RHA) is commonly used for the treatment of comminuted radial head fractures. Indications as well as implant types continue to evolve. RHA has had good outcomes with midterm longevity. The literature is limited to small case series with varying implant types, and larger studies are needed to determine the optimal implant type and radial head diameter. METHODS: A retrospective analysis of RHA cases performed by 75 surgeons at 14 medical centers in an integrated health care system between 2006 and 2017 was completed. Patient demographics, comorbidities, implant type and head diameter, and indications for revision were recorded. Patients' in-person clinical visit data were recorded. Patients were also contacted via telephone at a minimum of 2 years to obtain abbreviated Disabilities of the Arm, Shoulder, and Hand questionnaire and Oxford scores. Implant survivorship was also captured within our integrated system. RESULTS: 405 cases met our inclusion criteria. Mean age was 51.5 ± 15.5 years (range 16-88 years) and more common in females (62%). Chart review and telephone follow-up was performed at a mean of 68.9 ± 31.5 months (range 24-146 months). Our study found that revision rate was positively correlated with increasing radial head diameter. A 26-mm head had 7.7 odds of revision compared to a size 18-mm head (95% confidence interval 1.2-150.1). More than 95% of revision cases were performed within the first 36 months of the index procedure. Obese patients had a significantly lower mean postoperative Oxford score (35.5) compared to controls (38.3) (P = .02). There was a significantly higher overall reoperation rate for terrible triad (18.4%) vs. isolated injuries (10.4%) (P = .04). There was no difference between Acumed Anatomic and Evolve radial head implants in overall reoperation, implant revision, postoperative range of motion, or patient-reported outcomes. CONCLUSIONS: Risk of revision is directly correlated with implanted radial head diameter. There were no differences in outcomes and complications between the 2 main implants used. Individuals who did not undergo a revision by 3 years' time tend to retain the implant. Terrible triad injuries had a higher all-cause reoperation rate than isolated radial head fractures, but no difference in the rate of RHA revision. These data reinforce the practice of downsizing radial head implant diameter.

PURPOSE: Hamstring autograft (HA) is commonly used for primary anterior cruciate ligament reconstruction (ACLR). However, if the harvested HA is inadequate in diameter, it is often augmented with an allograft tendon, forming a hybrid graft (HY). This study sought to evaluate aseptic revision risk following HA versus HY ACLR. METHODS: A retrospective cohort study was performed using data obtained from our healthcare system's ACLR registry. Patients ≤ 25 years of age who underwent primary isolated ACLR were identified (2005-2020). Graft type and diameter size was the primary exposure of interest: < 8 mm HA and ≥ 8 mm HY. A secondary analysis was performed to examine 7 mm HA and 7.5 mm HA vs ≥ 8 mm HY. Propensity score-weighted Cox proportional hazard regression was used to evaluate the risk of aseptic revision. RESULTS: The study sample included 1,945 ACLR: 548 ≥ 8 mm HY, 651 7 mm HA, and 672 7.5 mm HA. The crude cumulative aseptic revision probability at 8-years for ≥ 8 mm HY was 9.1%, 11.1% for 7 mm HA, and 11.2% for 7.5 mm HA. In adjusted analysis, no difference in revision risk was observed for < 8 mm HA (hazard ratio [HR] 1.15, 95% confidence interval [CI] 0.72-1.82), 7 mm HA (HR 1.23, 95% CI 0.71-2.11), or 7.5 mm HA (HR 1.16, 95% CI 0.74-1.82) compared to ≥ 8 mm HY. CONCLUSION: In a US-based cohort of ACLR patients aged ≤ 25 years, we failed to observe any differences in aseptic revision risk for HA < 8 mm compared to HY ≥ 8 mm. Augmentation of a HA as small as 7 mm is not necessary to prevent a revision surgery. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: Several treatment options exist for the treatment of massive, irreparable rotator cuff tears. A novel technique has been described whereby an acellular dermal allograft is secured to the greater tuberosity which acts as an interpositional tissue preventing bone-to-bone contact between the greater tuberosity and acromion. The preliminary results of this arthroscopic procedure are being presented. METHODS: Patients who underwent a biologic tuberoplasty procedure between 2015 and 2022, by a single surgeon, were included in this study. Pre- and postoperative American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and visual analogue pain scores (VAS) were prospectively recorded and retrospectively reviewed. Postoperative MRI was obtained in some cases. Paired t-test was used to calculate significance set at <0.05. RESULTS: Ten patients met the inclusion criteria. The mean age was 70.4+4.7 years (range 65-78). There were five males. The mean length of follow-up was 21+27 months (range six to 95 months). There was significant improvement in ASES (24.3+4 to 91.5+10.3, P<0.00001), SANE (22.5+10.3 to 88+11.6, P<0.00001), and VAS (8.8+0.6 to 1.1+2.5, P<0.00001). MRI was obtained in seven patients at a mean of 5.3+2.9 months and showed a healed graft to the tuberosity in all cases. CONCLUSION: Biologic tuberoplasty is an effective procedure in improving pain and functional outcomes in patients with massive, irreparable rotator cuff tears.
RESUMO
There are several emerging treatments for patients with massive rotator cuff tears. Biologic tuberoplasty is still in its infancy but holds promise for improving pain and function by biologically covering a bare tuberosity with a dermal allograft to prevent bone-to-bone contact between the tuberosity and the undersurface of the acromion. Balloon arthroplasty is a technique of widespread interest, with the device recently gaining FDA approval. Anterior cable reconstruction uses the autologous long head of the biceps tendon to reconstruct the anterior cable of the rotator cuff. Tendon transfers, specifically lower trapezius tendon transfer, have now been established as a viable option especially in patients who want to regain active external rotation.

Background: Compare the recurrence rate of paresthesias in patients undergoing primary cubital tunnel surgery in those with and without wrapping of the ulnar nerve with the human amniotic membrane (HAM). Methods: A retrospective investigation of patients undergoing primary cubital tunnel surgery with a minimum 90-day follow-up was performed. Patients were excluded if the nerve was wrapped using another material, associated traumatic injury, simultaneous Guyon's canal release, or revision procedures. Failure was defined as those patients who experienced initial complete resolution of symptoms (paresthesias) but then developed recurrence of paresthesias. Results: A total of 57 controls (CON) and 21 treated with HAM met our inclusion criteria. There was a difference in the mean age of CON (48.4 ± 13.5 years) and HAM (30.6 ± 15) (P< 0.0001). There was no difference in gender mix (P=0.4), the severity of symptoms (P=0.13), and length of follow-up (P=0.084). None of 21 (0%) treated with HAM developed recurrence of symptoms compared to 11 of 57 (19.3%) (P=0.03) (CON). Using a multivariate regression model adjusted for age and procedure type, CON was 24.4 (95% CI=1.26-500, P=0.0348) times higher risk than HAM of developing a recurrence of symptoms. Conclusion: The HAM wrapping used in primary cubital tunnel surgery significantly reduced recurrence rates of paresthesias. Further prospective studies with randomization should be carried out to better understand the role HAM can play in cubital tunnel surgery.
RESUMO
We present a case of a 60-year-old male who has undergone Achilles' tendon repair with amnion augmentation on the right side. Before the surgery, liposomal bupivacaine was requested by the patient, and this was used to block the popliteal and adductor canal nerves for intraoperative anesthetic and postoperative pain control. The patient understood the benefits and risks of the regional nerve block with this medication and its off-label use. After the surgery, the patient underwent an irregular course of anesthetic, including delayed motor weakness, and became non-weight-bearing temporarily. The motor block was inconsistent and non-linear. Initially, the motor block completely resolved with a return to the sensation after three days. Then, on day four, a complete motor block developed, which resolved gradually over the next four days. After 10 days, the patient had full resolution of symptoms. He denies any pain since the surgery.
RESUMO
BACKGROUND: Radial head arthroplasty (RHA) is commonly performed for isolated comminuted radial head fractures and in conjunction with traumatic elbow instability. However, there is a paucity of literature directly describing the characteristics and outcomes of patients who undergo RHA in a community-based setting. We describe a cohort of 970 RHA performed in the California regions of a US integrated health care system over a 9-year period. Patient demographics, implant selection, 90-day acute postoperative events, and cumulative reoperation/revision rates are included. METHODS: Patients aged ≥18 years who underwent primary RHA were identified (2009-2017). Patient characteristics and demographics, including age, body mass index, gender, diabetes status, American Society of Anesthesiologists (ASA) classification, primary diagnosis, and concomitant procedures were described. Crude cumulative revision and reoperation probabilities were calculated as 1 minus the Kaplan-Meier estimator, with follow-up time calculated as the time from the index RHA to revision/reoperation date for those with the outcome of interest and time from index RHA to censoring date (eg, date of death, health care termination, study end date [March 31, 2018]) for those without the outcome. Ninety-day postoperative incidence of emergency department (ED) visit, readmission, and mortality was calculated as the number of patients with the event of interest over the number of patients at risk. RESULTS: A total of 970 patients underwent primary unilateral RHA by 205 surgeons during the study period. Annual procedure volume increased from 53 procedures in 2009 to 157 procedures in 2017. More patients were female, without diabetes, and had an ASA classification of 1 or 2. Fracture was the predominant indication for RHA (98.4%) and more than half (54.3%) had concomitant procedures performed. Most implants were press fit (63.2%) over loose fit, and >90% were monopolar. Three-year cumulative revision and reoperation probabilities following RHA were 6.5% (95% confidence interval [CI] = 5.0%-8.5%) and 8.2% (95% CI = 6.5%-10.3%), respectively. Revisions and reoperations tended to occur within the first postoperative year. Of the 970 RHA patients, 83 (8.5%) had a 90-day ED visit, 58 (6.0%) had a 90-day readmission, and 1 (0.1%) died within a 90-day postoperative period. CONCLUSION: This large cohort of RHA patients provides information about the practice of RHA at large and in the community. Surgeons are performing more RHA over time and choosing press fit stems more often. Revisions and reoperations tended to occur early. Readmission and ED visits were low but not negligible, with pain being the most common reason for ED visit.

OBJECTIVE: Superior capsule reconstruction (SCR) is a treatment option for irreparable massive rotator cuff tears (MRCT). The purpose of this study is to describe a classification system for graft integrity and tear location. METHODS: Patients who underwent SCR at a single institution were included. Pre-operative age, gender, prior surgery, Hamada grade, and Goutallier stage were recorded. An MRI was performed postoperatively to assess graft integrity and tear location. RESULTS: 53 patients met inclusion criteria. Mean age was 60.1 ± 7.9 years. A post-operative MRI was performed in 42 (80%) patients at a mean of 14 ± 7 months (range, 6-40 months). MRIs demonstrated an intact graft in 16 (38%) shoulders. Of the 26 graft tears, 14 (54%) were from the glenoid, 5 (19%) mid-substance, 6 (23%) from the tuberosity, and 1 (3.8%) had complete graft absence. CONCLUSION: Graft tears are common following SCR. We describe four different graft tear locations and submit a classification system that can be used in future studies to better compare outcomes based on graft integrity and tear location. Clinical correlation with graft integrity and graft tear location needs to be further investigated.

We present the technique of biologic tuberoplasty, where an acellular dermal allograft is used to cover the tuberosity in patients with massive irreparable cuff tears to prevent bone-to-bone contact between the tuberosity and acromion when active elevation is attempted. This technique can be performed in patients with massive rotator cuff tears who are low-demand and have significant medical comorbidities, poor bone quality, or who are not candidates for a reverse shoulder arthroplasty or who cannot tolerate a lengthy rehabilitation protocol. It is less time-consuming than a superior capsule reconstruction and more bone-sparing than traditional tuberoplasty. Patients with massive rotator cuff tears involving the supraspinatus and a portion of the infraspinatus lose their force couple, leading to superior humeral head migration with abutment of the tuberosity against the acromion upon deltoid activation. The center of rotation moves superiorly with deltoid contraction, developing an acromiohumeral articulation. This results in bone-to-bone contact between the acromion and humerus, leading to pain and acetabularization of the acromion over time. Coverage of the tuberosity with the acellular dermal allograft acts as an interpositional tissue and prevents bone-to-bone contact between the tuberosity and acromion.
RESUMO
Chronic distal biceps tendon ruptures present a unique surgical challenge due to tendon retraction and shortening as well as muscle atrophy. Several graft choices and fixation methods have been described, with no one technique proving superior to date. We describe a technique wherein a tibialis anterior tendon allograft is Pulver-Taft weaved through the muscle belly to achieve incorporation with the muscle and tendonous fascia to achieve superior pull-out strength.
RESUMO
CASES: We present 3 patients who underwent ulnar nerve transposition and wrapping of the nerve with human amniotic membrane (HAM). All 3 patients subsequently required a reoperation for the original pathologic condition (not for ulnar nerve symptoms), necessitating the exploration and dissection of the transposed ulnar nerve. We demonstrate the lack of scar formation and ease of separation between nerve and surrounding tissue, as well as histology in one case taken from the perineural tissues (previous amniotic membrane), demonstrating no inflammatory cells or absence of scar tissue formation. CONCLUSION: Exploration and dissection of a previously transposed ulnar nerve can be facilitated by wrapping the nerve with HAM to prevent scarring and perineural fibrosis.

BACKGROUND: Osteochondral allograft (OCA) transplantation has evolved into a first-line treatment for large chondral and osteochondral defects, aided by advancements in storage protocols and a growing body of clinical evidence supporting successful clinical outcomes and long-term survivorship. Despite the body of literature supporting OCAs, there still remains controversy and debate in the surgical application of OCA, especially where high-level evidence is lacking. PURPOSE: To develop consensus among an expert group with extensive clinical and scientific experience in OCA, addressing controversies in the treatment of chondral and osteochondral defects with OCA transplantation. STUDY DESIGN: Consensus statement. METHODS: A focus group of clinical experts on OCA cartilage restoration participated in a 3-round modified Delphi process to generate a list of statements and establish consensus. Questions and statements were initially developed on specific topics that lack scientific evidence and lead to debate and controversy in the clinical community. In-person discussion occurred where statements were not agreed on after 2 rounds of voting. After final voting, the percentage of agreement and level of consensus were characterized. A systematic literature review was performed, and the level of evidence and grade were established for each statement. RESULTS: Seventeen statements spanning surgical technique, graft matching, indications, and rehabilitation reached consensus after the final round of voting. Of the 17 statements that reached consensus, 11 received unanimous (100%) agreement, and 6 received strong (80%-99%) agreement. CONCLUSION: The outcomes of this study led to the establishment of consensus statements that provide guidance on surgical and perioperative management of OCAs. The findings also provided insights on topics requiring more research or high-quality studies to further establish consensus and provide stronger evidence.
RESUMO
PURPOSE: Total elbow arthroplasty (TEA) can be used, with varying degrees of success, for the treatment of rheumatoid arthritis, osteoarthritis, and distal humerus fractures and their sequelae in elderly patients. Some of the largest studies of TEA have included data from more than 20 years ago and may not reflect the current practice of TEA. We sought to describe a modern cohort of patients who underwent TEA in a United States integrated health care system. METHODS: All patients aged 18 years and older who underwent primary unilateral TEA from January 1, 2009, through March 31, 2018, were identified to conduct a descriptive study. The patients' characteristics and demographics, including age, body mass index, sex, diabetes status, American Society of Anesthesiologists classification, and surgical indication, were recorded. The crude cumulative revision probability as well as the 90-day postoperative incidence rate of emergency department visit, readmission, and mortality was calculated. RESULTS: A total of 170 patients met our inclusion criteria. The annual procedure volume nearly doubled, from 11 procedures in 2009 to 21 procedures in 2017. The most common indication for TEA was fracture (40.6%), followed by rheumatoid arthritis (36.5%). At 4-year follow up, the crude cumulative revision probability was 9.8% (95% confidence interval, 5.6%-16.9%). Of the 170 patients who underwent TEA, 43 (25.3%) experienced a 90-day emergency department visit, 24 (14.1%) experienced a 90-day readmission, and 2 (1.2%) died within 90 days postoperatively. CONCLUSIONS: This cohort of patients who underwent TEA using modern implants showed a notable increase in the volume of TEA over the study period, with more TEAs performed for trauma. The incidence of readmission and emergency department visits following TEA were high in this study. Further studies are needed to better define the current practice of TEA in the community at large. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Ulnar collateral ligament reconstruction of the elbow has evolved substantially since its introduction in 1974. Numerous variations of the surgery have been introduced, including modifications in tunnel creation, graft tensioning, and fixation. These changes have aimed to improve overall quality of the reconstruction; however, even the most commonly used techniques still present many challenges. We describe a technique for ulnar collateral ligament (UCL) reconstruction using bisuspensory button fixation and a single tunnel on both the ulnar and humeral sides. This technique avoids many of the most common complications and methods of failure of UCL reconstruction, provides immediate strong graft fixation, and offers the surgeon a technically less demanding procedure.
