Project description:The popliteus tendon plays a critical role in restraining the tibia against external rotation. It is often injured in the setting of posterolateral corner injuries. However, it is rarely injured in isolation from other structures of the posterolateral corner. This Technical Note describes an open anatomic reconstruction of the popliteus tendon. Although several techniques exist, this technique has been biomechanically validated and shown to have good outcomes. An early rehabilitation protocol focused on protected range of motion, edema control, quadriceps strengthening, and pain control is essential for maximizing patient outcomes.

Project description:Patellar tendon ruptures are the third most common injury to the extensor mechanism. These injuries are debilitating to the patient, and delays in treatment can present a challenge to the treating surgeon. Chronic patellar tendon injuries are rare and are more difficult to manage given proximal patellar retraction, scarring, and atrophy of surrounding tissues. There is no consensus on the optimal approach for treatment, and numerous reconstruction techniques have been described using a variety of graft choices and fixation methods. We describe our surgical technique for a 3-fold reconstruction of a chronic patellar tendon rupture using an Achilles tendon allograft augmented with a vascularized ipsilateral hamstring tendon autograft and additional FiberTape augmentation. The aim of this procedure is to restore patellar height and prevent extensor lag.

Project description:We present a technique for anterior cruciate ligament (ACL) reconstruction using hamstring tendon autograft with preserved tibial insertions. The tendons, harvested with an open-ended tendon stripper while their tibial insertions are preserved, are looped around to prepare a quadrupled graft. The femoral tunnel is drilled independently through a transportal technique, whereas the tibial tunnel is drilled in a standard manner. The length of the quadrupled graft and loop of the RetroButton is adjusted so that it matches the calculated length of both tunnels and the intra-articular part of the proposed ACL graft. After the RetroButton is flipped, the graft is manually tensioned with maximal stretch on the free end, which is then sutured to the other end with preserved insertions. We propose that preserving the insertions is more biological and may provide better proprioception. The technique eliminates the need for a tibial-side fixation device, thus reducing the cost of surgery. Furthermore, tibial-side fixation of the free graft is the weakest link in the overall stiffness of the reconstructed ACL, and this technique circumvents this problem. Postoperative mechanical stability and functional outcome with this technique need to be explored and compared with those of ACL reconstruction using free hamstring autograft.

Project description:PurposeTo assess the clinical outcomes comparing rectangular bone-tendon-bone (BTB) grafts and double-bundle hamstring tendon (HM) grafts used for anatomic anterior cruciate ligament (ACL) reconstruction in young female athletes.MethodsFrom January 2014 to November 2017, young female athletes 20 years or younger who underwent primary ACL reconstructions by a single surgeon were identified. Patients with concomitant injuries, not being a regular sports participant, the existence of contralateral ACL reconstruction, and who did not have a minimum of 1-year follow-up were excluded. We searched the rate and time for return-to-play, clinical outcomes including chronological instrumental side-to-side tibial translation difference, and muscle strength. Second ACL injury rates between the 2 groups during follow-up period were evaluated.ResultsTwenty-seven BTB ACL reconstructions and 29 HM ACL reconstructions were performed. The mean follow-up periods were 35.2 months in the BTB group and 33.8 months in the HM group. The BTB group showed better knee stability in mean side-to-side translational difference via arthrometric testing of 0.6 mm in the BTB versus 1.7 mm in the HM group at 5 months (P = .01) and 1.1 mm and 2.0 mm at 12 months, respectively (P = .02). There was no significant side-by-side difference in quadriceps muscle strength ratio, but the hamstring muscle strength was significantly better in the BTB group. The graft reinjury rate in the BTB group and the HM group was 0% (0/27) and 10.3% (3/29) (P = .09), respectively. In contrast, contralateral ACL injuries occurred in 17.3% (4/27) of the BTB group and 3.5% (1/29) of the HM group (P = .12).ConclusionsFor young female athletes aged 20 years or younger, the BTB group had better knee instrumental stability than the HM group without range of motion loss or knee extensor muscle strength deficit. Although there was no statistical significance in terms of second ACL injury, we observed fewer graft rerupture and an increasing rate of contralateral ACL injuries in the BTB group.Level of evidenceLevel III, retrospective comparative study.

Project description:PurposeTo evaluate whether preoperative magnetic resonance imaging (MRI) measurements of multiple tendon autograft sources could be used to improve estimates of intraoperative hamstring tendon autograft (HTA) diameter.MethodsPatients who underwent anterior cruciate ligament reconstruction with HTA at our institution were identified through electronic health records. Preoperative MRI tendon measurements of the patellar tendon (PT) length, PT width, PT thickness, quadriceps tendon thickness, semitendinosus tendon (ST) cross-sectional area (CSA), and gracilis tendon (GT) CSA were conducted by 2 independent evaluators using digital imaging measurement tools.ResultsA total of 53 patients met the inclusion criteria, with a mean HTA diameter of 7.98 ± 0.7 mm. Height greater than 1.63 m, weight greater than 63.4 kg, PT length greater than 4.2 cm, PT thickness greater than 0.33 cm, ST CSA greater than 10.8 mm2, and GT CSA greater than 6.3 mm2 were associated with an HTA of 8 mm or greater (P < .005). Female sex was associated with an HTA of less than 8 mm (P < .05). PT length, PT thickness, and GT CSA were the strongest predictors of an HTA of 8 mm or greater and were combined into an additive logistic regression model: Score = -23.24 + (1.68 × PT length) + (20.104 × PT thickness) + (1.48 × GT CSA). If the score was greater than 0.237, the HTA graft diameter was predicted to be 8 mm or greater with 83% specificity, 91% sensitivity, and 87% accuracy.ConclusionsBy combining PT length and PT thickness measurements with GT CSA measurements in a logit function model, we were able to show improved overall specificity, sensitivity, and accuracy of estimated HTA diameters in our data set when compared with assessments of anthropometric, ST CSA, GT CSA, or combined ST-GT CSA measurements in isolation.Clinical relevancePreoperative MRI measurements may be used to screen whether a patient is likely to have an 8-mm graft in the setting of anterior cruciate ligament reconstruction with HTA and thus may help guide graft choice.

Project description:IntroductionThe use of implant in anterior cruciate ligament (ACL) reconstruction has been associated with several drawbacks including graft injury, implant osteolysis, implant migration and soft tissue irritation. Implant-free ACL reconstruction surgery offers additional benefits of cost-effective, improved graft incorporation and ease of revision surgery. Our study aimed to compare the functional outcome of ACL reconstruction by using bone-patellar tendon autograft with press-fit fixation technique and hamstring autografts with implant.MethodsA prospective cohort study design was used. Between March 2013 and March 2014, 12 patients underwent patella tendon-bone graft fixated by press-fit fixation technique (implant-free), while 24 patients underwent ACL reconstruction using implant-fixated hamstring tendon graft. Objective functional outcome was measured by using rolimeter, and subjective functional outcome was measured according to the functional score of IKDC, Tegner-Lysholm and KOOS.ResultsBoth techniques have shown no significant difference in terms of functional outcome, whether assessed by rolimeter measurement, IKDC score, Tegner-Lysholm, KOOS score between implant group and implant-free group, preoperatively and postoperatively.DiscussionOur study results are in line with several other studies with various follow-up time and systematic review. With the right technique, graft harvesting of patella tendon-tibial tuberosity bone block can be successfully performed, and associated donor site morbidity can be avoided.ConclusionPatients who underwent ACL reconstruction using implant-free technique by press-fit fixation had comparable outcome with ACL reconstruction with implant, objectively and subjectively. This technique should be further revisited and reevaluated.

Project description:BackgroundBone-patellar tendon-bone (bone-tendon-bone) and four-strand hamstring tendon grafts (hamstring) are the most commonly utilized autografts for primary anterior cruciate ligament (ACL) reconstruction. Existing clinical trials, registry studies, and meta-analyses offer conflicting opinions regarding the most favorable graft choice.Questions/purposesWhich graft type for ACL reconstruction (bone-tendon-bone or hamstring) has a higher risk of (1) graft rupture and/or (2) graft laxity?MethodsWe performed a meta-analysis of randomized controlled trials (RCTs), prospective cohort studies, and high-quality national registry studies to compare the outcomes of primary ACL reconstruction with bone-tendon-bone autograft or hamstring autograft. Studies that compared these graft types were identified through a comprehensive search of electronic databases (PubMed, MEDLINE, EMBASE, and the Cochrane Library). Two independent reviewers utilized the Jadad scale for RCT study quality and the Modified Coleman Methodology Score for prospective comparative and registry study quality. The included studies were analyzed for the primary outcome measure of graft rupture with or without revision ACL surgery. In surviving grafts, secondary outcomes of graft laxity were quantified by KT1000/2000™ testing, a positive pivot shift test, and a positive Lachman test. Meta-analysis was performed with Review Manager. A total of 47,613 ACL reconstructions (39,768 bone-tendon-bone and 7845 hamstring) from 14 RCTs, 10 prospective comparative studies, and one high-quality national registry study were included in this meta-analysis. Mean age was 28 years in both groups. Sixty-three percent of patients in the bone-tendon-bone cohort were men versus 57% of patients in the hamstring cohort. Mean followup was 68 ± 55 months.ResultsTwo hundred twelve of 7560 (2.80%) bone-tendon-bone grafts ruptured compared with 1123 of 39,510 (2.84%) in the hamstring group (odds ratio = 0.83, 95% confidence interval, 0.72-0.96; p = 0.01). The number needed to treat analysis found that 235 patients would need to be treated with a bone-tendon-bone graft over a hamstring tendon graft to prevent one graft rupture. Instrumented laxity analysis showed that 22% (318 of 1433) of patients in the bone-tendon-bone group had laxity compared with 18% (869 of 4783) in the hamstring tendon group (odds ratio = 0.86; p = 0.16). Pivot shift analysis showed a positive pivot shift in 19% (291 of 1508) of the bone-tendon-bone group compared with 17% (844 of 5062) in the hamstring group (odds ratio = 0.89; p = 0.51). Lachman testing showed a positive Lachman in 25% (71 of 280) of patients receiving bone-tendon-bone grafts compared with 25% (73 of 288) in the hamstring group (odds ratio = 0.96; p = 0.84).ConclusionsIn this meta-analysis of short- to mid-term followup after primary ACL reconstruction, hamstring autografts failed at a higher rate than bone-tendon-bone autografts. However, failure rates were low in each group, the difference observed was small, and we observed few differences between graft types in terms of laxity. Both graft types remain viable options for primary ACL reconstruction, and the difference in failure rate should be one part of a larger conversation with each individual patient about graft selection that should also include potential differences in donor site morbidity, complication rates, and patient-reported outcome measures. Continued prospective collection of patient data will be important going forward as we attempt to further characterize the potential differences in outcomes attributable to graft selection.Level of evidenceLevel III, therapeutic study.

Project description:BackgroundInfection following Achilles tendon surgery is a devastating complication and can be difficult to treat and often leads to poor outcomes. A number of treatments have been described, but there is little information concerning outcomes of these treatments. Our purpose was to evaluate the clinical and functional outcomes of patients who have undergone treatment for an infected Achilles tendon after acute and chronic midsubstance repair.MethodsWe retrospectively reviewed the medical records of 20 patients who had undergone surgical treatment for an infected Achilles tendon between 2000 and 2016. The mean follow-up time was 21 months (range, 2-68 months). All patients underwent extensive debridement of the tendon with removal of all infected tissue and foreign material. Soft tissue wound coverage was utilized for large wounds that were not amenable to primary or secondary closure. All patients received culture-specific intravenous (IV) antibiotics for 3 to 6 weeks. Postoperatively, the extremity was immobilized in a splint followed by a cast until the wound was healed. The cast was then replaced with a walking boot and the patients were provided a physical therapy program. Functional outcomes were measured using the Foot and Ankle Ability Measure (FAAM) Activity of Daily Living (ADL) scale.ResultsAll wounds had healed at the time of last follow-up. Three patients (15%) required an unplanned return to the operating room for repeat debridement. All patients were able to walk without the use of a gait aid. Five patients (25%) required continued use of a boot or brace during ambulation. Fourteen patients participated in the FAAM ADL survey. There were 6 patients lost to follow-up. The average FAAM score was 87 (range, 71.4-100). At last follow-up, most patients reported their overall function as "normal" or "nearly normal." Eradication of infection and satisfactory functional results can be attained after radical debridement, wound closure, and administration of culture-specific IV antibiotics.Level of evidenceLevel IV, retrospective case series.

Project description:BackgroundQuadriceps tendon (QT), bone-patellar tendon-bone (BPTB), and hamstring tendon (HT) autografts are widely used for anterior cruciate ligament reconstruction (ACLR), but the optimal autograft choice remains controversial. This study assessed the treatment effects of QT versus BPTB and HT autografts for ACLR.MethodsThe PubMed, Embase, and Cochrane Library databases were systematically searched for eligible studies published from inception until July 2022. Effect estimates were presented as odds ratios (OR) and weighted mean differences (WMD) with 95% confidence intervals (CI) for categorical and continuous variables, respectively. All pooled analyses were performed using a random-effects model.ResultsTwenty-one studies (3 randomized controlled trials [RCTs], 3 prospective studies, and 15 retrospective studies) involving 2964 patients with ACLR were selected for meta-analysis. Compared with the HT autograft, the QT autograft was associated with a reduced risk of graft failure (OR: 0.46; 95% CI: 0.23-0.93; P = 0.031). Compared with the BPTB autograft, the QT autograft was associated with a reduced risk of donor site pain (OR: 0.16; 95% CI: 0.10-0.24; P < 0.001). Moreover, the QT autograft was associated with a lower side-to-side difference than that observed with the HT autograft (WMD: - 0.74; 95% CI: - 1.47 to - 0.01; P = 0.048). Finally, compared with the BPTB autograft, the QT autograft was associated with a reduced risk of moderate-to-severe kneecap symptoms during sports and work activities (OR: 0.14; 95% CI: 0.05-0.37; P < 0.001).ConclusionsThe findings of this study suggest that the QT autograft can be defined as a safe and effective alternative choice for ACLR, but its superiority is yet to be proven by RCTs and prospective studies.
