This Week in Orthopedics — Jul 24, 2026

Welcome to This Week in Orthopedics. This week we're covering 7 notable papers spanning spine surgery, knee arthroplasty, arthroscopy, and sports medicine. Let's dive in.

In the realm of spine surgery, two significant cohort studies evaluated reconstruction strategies and alignment goals. Writing in Spine, Yacob and colleagues conducted a retrospective cohort study of 4,412 patients in the United States to compare multilevel posterior cervical laminoplasty versus multilevel posterior cervical laminectomy and fusion [1]. The authors found that laminoplasty was associated with roughly half the risk of operative adjacent segment disease and all-cause reoperation compared to laminectomy and fusion [1]. Interestingly, laminectomy and fusion was selected at more than twice the rate of laminoplasty despite these higher reoperation risks [1]. Complementing this cervical work, Mohanty and colleagues published a study in The Journal of Bone and Joint Surgery evaluating the T4-L1-hip axis in 427 patients undergoing long-segment posterior spinal fusion for adult spinal deformity [2]. Using multivariable analysis, they demonstrated that deviation from a harmonious alignment—measured via the T4-pelvic angle and L1-pelvic angle mismatch—conferred a U-shaped mechanical complication risk, where both undercorrection and overcorrection increased the likelihood of implant-related failures and complications [2].

Turning to arthroscopy, sports medicine, and ligamentous reconstruction, several studies explored surgical technique modifications. In Arthroscopy, Gosnell and colleagues reviewed 139 patients who underwent meniscal allograft transplantation, comparing suture-only fixation to bone bridge-in-slot and bone plug techniques [3]. Patients who underwent suture-only fixation experienced a significantly higher meniscus-specific reoperation rate of 31.3 percent, compared to just 8.9 percent for bone bridge-in-slot and 10.9 percent for bone plug fixation, with meniscectomy and meniscal repair representing the most common subsequent surgeries [3]. In knee and patellofemoral disorders, Vincent and colleagues conducted a prospective single-center study in Knee Surgery, Sports Traumatology, Arthroscopy examining 121 patients undergoing isolated medial patellofemoral ligament reconstruction for recurrent patellar dislocation [7]. They compared patients with an increased tibial tubercle-trochlear groove distance of 20 millimeters or greater against those with a normal distance, finding no significant differences in postoperative International Knee Documentation Committee scores, functional improvement, complication rates, or instability recurrence [7]. This suggests that an increased tibial tubercle-trochlear groove distance should not be used in isolation to mandate bony realignment when low-grade trochlear dysplasia and patella alta are absent [7]. In hip preservation, two studies in The American Journal of Sports Medicine examined midterm outcomes at a minimum of 5 years. Kahana-Rojkind and colleagues performed a propensity-matched study of 94 patients undergoing arthroscopic subspine decompression for femoroacetabular impingement, finding durable patient-reported outcome improvements and survivorship comparable to matched controls without subspine impingement [4]. Meanwhile, Quesada-Jimenez and colleagues compared labral reconstruction with labral repair in 68 matched patients undergoing revision hip arthroscopy [5]. Both techniques yielded significant and comparable improvements in patient-reported outcomes, meeting minimal clinically important thresholds at similar rates with low complication profiles [5].

In knee arthroplasty, Tay and colleagues investigated item-level longitudinal associations using registry data from New Zealand published in Knee Surgery, Sports Traumatology, Arthroscopy [6]. Analyzing 9,384 total knee arthroplasties and 2,424 unicompartmental knee arthroplasties across up to 15 years of follow-up, the authors identified that question 1 on the Oxford Knee Score, addressing overall pain, demonstrated the strongest and most consistent association with patient satisfaction, showing strong discriminatory performance that approached the full multi-item instrument [6].

If you only have time for one paper this week, make it the cohort study by Yacob and colleagues in Spine comparing laminoplasty to laminectomy and fusion for multilevel posterior cervical pathology [1]. It provides robust registry-level evidence that laminoplasty cuts the risk of reoperation and adjacent segment disease in half, challenging the predominant use of fusion in clinical practice [1].

Here are the key takeaways from this week in Orthopedics. Multilevel posterior cervical laminoplasty is associated with a substantially lower risk of reoperation and adjacent segment disease compared to laminectomy and fusion [1]. In adult spinal deformity surgery, maintaining a harmonious T4-L1-pelvic alignment is critical, as both under- and overcorrection increase mechanical complication risks [2]. For meniscal allograft transplantation, suture-only fixation yields significantly higher reoperation rates than bone bridge-in-slot or bone plug techniques [3]. In isolated medial patellofemoral ligament reconstruction, an increased tibial tubercle-trochlear groove distance does not compromise outcomes if severe trochlear dysplasia and patella alta are absent [7]. Finally, overall pain is the single most dominant driver of patient satisfaction following total and unicompartmental knee arthroplasty [6].
