Welcome to OrthoDigest, your daily podcast of orthopaedic literature summaries, brought to you by Joint Venture Orthopaedics. Today is Sunday, so we are covering sports medicine. We have four open-access studies for you today, spanning cartilage repair techniques, elbow dislocation management, shoulder arthroplasty outcomes, and ACL reconstruction strategies. As always, links to every manuscript are in the episode description — all are open access. Let's get started.
Our first study is a case report with technique description by Vega and colleagues, published in Video Journal of Sports Medicine. This presents a surgical technique for addressing complex knee pathology combining meniscal root tears with chondral defects.
The authors present a case of a fifty-one-year-old female who sustained both a posterior medial meniscal root tear and two focal grade four chondral lesions on the medial femoral condyle, each approximately two centimeters in diameter. This combination of pathology presents a challenging clinical scenario requiring attention to both meniscal and cartilage damage.
The surgical technique involves transtibial medial meniscal posterior root repair combined with aragonite-based scaffold implantation for the focal osteochondral defects. The authors describe this as a single-stage procedure that addresses both the meniscal pathology and the cartilage defects simultaneously. Aragonite-based scaffolds are synthetic osteochondral implants designed to treat both cartilage and subchondral bone defects in a single intervention.
The procedure was successfully completed in this patient, demonstrating the technical feasibility of combining these approaches. The authors reference supporting data from multicenter randomized controlled trials showing that aragonite scaffolds achieve greater than seventy-five percent defect filling in eighty-eight percent of scaffold cases versus thirty percent in the microfracture group. Failure rates were notably lower with scaffolds at seven point two percent compared to twenty-one point four percent for microfracture. Additionally, case series with three-year follow-up have demonstrated KOOS and IKDC scores in the nineties.
So what can you do differently? The authors suggest that aragonite-based scaffolds represent a fast and accessible option for superficial chondral and subchondral lesions. For patients presenting with combined meniscal root tears and focal cartilage defects, this technique offers a single-stage solution that may avoid the need for staged procedures. However, the authors emphasize respecting indications and contraindications until further comparative effectiveness studies are developed.
The authors acknowledge that this is an emerging treatment option and stress the importance of appropriate patient selection. They note that while synthetic osteochondral scaffolds have shown superiority to microfracture in comparative studies, further research is needed to establish their role compared to other advanced cartilage techniques, particularly in complex cases involving multiple pathologies.
Shifting to upper extremity trauma, our second study is a systematic review by Albright and colleagues published in Orthopaedic Journal of Sports Medicine, examining return to sport outcomes following elbow dislocation in athletes.
The authors conducted a comprehensive systematic review searching PubMed, Embase, Cochrane, and Web of Science databases through March twenty twenty-five. They identified nine studies covering nine hundred seventy athletes with elbow dislocations, extracting data on injury mechanisms, treatment approaches, complications, and return to sport outcomes.
The athlete population had a weighted mean age of twenty-nine point six years and was predominantly male, with three hundred twenty-eight of four hundred seventeen athletes being male. Mean follow-up across five studies was seventy-two months. Most athletes, specifically three hundred twenty, received nonoperative management, while ninety-seven of four hundred seventeen athletes underwent surgical treatment.
The primary finding was exceptionally high return to sport rates. Two hundred seventy-two of two hundred seventy-four athletes returned to any sporting activity, representing ninety-nine point three percent of patients. The mean time to return was eleven point four weeks, with a standard deviation of seven point seven weeks. Importantly, treatment approach influenced return timeline, with nonoperatively treated athletes returning sooner at eight point nine five weeks compared to sixteen point three weeks for surgically treated athletes.
Complications were relatively uncommon, occurring in only eighteen of one hundred sixty-one cases, representing eleven point two percent of dislocations. Functional outcomes were excellent, with Mayo Elbow Performance Score, Elbow Self-Assessment Score, and subjective elbow value scores all demonstrating excellent elbow performance after injury.
So what can you do differently? This data provides strong reassurance for counseling athletes with elbow dislocations. You can confidently tell patients that return to sport rates approach one hundred percent regardless of treatment modality, with most athletes returning within ten weeks. For decision-making between operative and nonoperative management, consider that while both approaches achieve excellent return rates, nonoperative management typically allows earlier return to sport.
As with any systematic review, the usual caveats around heterogeneity in study populations and treatment protocols apply, though the consistency of findings across multiple studies strengthens these conclusions.
Staying with return to sport themes, our third study is a multicenter retrospective analysis by Corban and colleagues published in Journal of Shoulder and Elbow Surgery, examining sport-specific predictors of performance following shoulder arthroplasty.
This American Shoulder and Elbow Surgeons multicenter study involved twenty-four surgeons across seventeen institutions from April twenty twenty-one to April twenty twenty-four. Nine hundred sixty-one patients completed sport-specific return to sport questionnaires, with five hundred thirty-seven patients participating in at least one sport preoperatively. The cohort had a mean age of sixty-eight point three years, mean BMI of twenty-eight point five, and was sixty-five point six percent male. Mean follow-up was twenty-four months.
The study assessed participation in seven specific sports: golf, pickleball, tennis, running, weightlifting, yoga, and swimming. Primary diagnoses included glenohumeral osteoarthritis in sixty-eight point two percent and rotator cuff arthropathy in eighteen point two percent of patients.
Return to sport outcomes were excellent overall. Eighty-nine point two percent of participants returned to sports postoperatively, with eighty point two percent reporting improved or unchanged performance. Most patients returned within three to six months postoperatively, accounting for forty-four point seven percent, with an additional twenty-six point seven percent returning within seven to twelve months. Patient satisfaction was high, with mean satisfaction scores of nine point one on a zero to ten scale.
Important differences emerged based on diagnosis and implant type. For patients with glenohumeral osteoarthritis, reverse total shoulder arthroplasty showed superior outcomes compared to anatomic total shoulder arthroplasty, with eighty-seven point nine percent versus seventy-eight point nine percent reporting improved or stable performance and higher satisfaction scores of nine point five versus nine point zero. Glenohumeral osteoarthritis diagnosis was protective against worse performance with an odds ratio of zero point two.
So what can you do differently? These findings should inform your preoperative counseling for shoulder arthroplasty patients interested in sports participation. You can confidently tell patients that return to sport rates approach ninety percent across various activities, with most returning between three to six months. For patients with glenohumeral osteoarthritis, consider that reverse total shoulder arthroplasty may offer advantages over anatomic arthroplasty for sport-specific outcomes.
The authors note several important limitations including retrospective design with patient recall bias, selection bias from voluntary participation, and heterogeneity from multiple diagnoses and surgical centers across the study population.
Our final study is a systematic review by Thamrongskulsiri and colleagues published in Orthopaedic Journal of Sports Medicine, examining clinical outcomes of cartilage procedures performed during primary anterior cruciate ligament reconstruction.
The authors conducted a systematic review of literature through July twenty twenty-five, identifying fourteen studies comprising one thousand three patients who underwent ACLR with intraoperatively visualized cartilage lesions. Study sample sizes varied from ten to two hundred sixty-nine patients, with mean ages ranging from twenty-eight to thirty-nine years and follow-up durations from two point one months to ninety-five months.
The key finding challenges conventional thinking about cartilage treatment during ACL reconstruction. Microfracture and debridement performed during primary ACLR did not consistently improve outcomes compared with no treatment. Specifically, Røtterud and colleagues found microfracture had significantly worse KOOS Sport and KOOS Quality of Life scores compared to no treatment. In contrast, more advanced techniques showed promise. Gudas and colleagues found osteochondral autograft transfer had significantly better outcomes than both microfracture and debridement.
Return to sport data, though limited, suggested differences between techniques. Thirty-eight point five percent of patients in the microfracture group returned to preinjury level compared to sixty-three point six percent in the osteochondral autograft group. Osteoarthritis progression was more frequent after microfracture, with forty-eight percent showing progression versus twenty percent in the debridement group.
Functional improvements varied by technique. Microfracture cases showed Lysholm score improvements from thirty-seven to eighty-three, while debridement improved from thirty-nine to eighty-seven. More advanced techniques like autologous chondrocyte implantation showed IKDC score improvements of thirty-nine points, and osteochondral allograft showed KOOS Quality of Life improvements of forty points.
So what can you do differently? This data suggests considering a more individualized approach to cartilage treatment during ACL reconstruction. For small, contained defects, the evidence does not support routine intervention with microfracture or debridement over observation. Reserve complex procedures like osteochondral autograft transfer or autologous chondrocyte implantation for symptomatic, high-demand patients with larger or more advanced lesions where the expected benefits clearly outweigh the risks and costs.
The authors acknowledge substantial limitations including heterogeneity in study designs, patient demographics, lesion characteristics, and outcome measures, along with most studies being level three or four evidence, preventing definitive conclusions about optimal cartilage treatment strategies during ACL reconstruction.
And that wraps up today's edition of OrthoDigest. We covered aragonite scaffold techniques for combined meniscal and cartilage repair, return to sport outcomes after elbow dislocation and shoulder arthroplasty, and cartilage treatment strategies during ACL reconstruction. As always, links to all manuscripts are in the episode description — they are all open access, so please do take a look. Thanks for listening, and we will see you tomorrow for hip.
