Patellar Tendon Lengthening: Rescue Procedure for Patella Baja.

ABSTRACT: Patella baja is a challenging pathologic condition that causes pain and functional restrictions and can even lead to premature osteoarthritis-even more so in cases of patella infera or cases associated with degeneration of the patellar tendon in which simple conservative treatment frequently is not resolutive. Several surgical options have been described for symptomatic patella baja: excision of the lower third of the patella, lengthening of the patellar tendon, reconstruction of the patellar tendon with allograft, and proximalization of the tibial tubercle. A combination of 2 or more of these treatments may be recommended in cases of significant patella baja. We present a simple and reproducible technique to address patella baja that combines a partial transposition of the tibial tubercle and patellar tendon lengthening using a subperiosteal patellar flap in continuity with the patellar tendon.

Frontal Tendon Lengthening Plasty for Treatment of Structural Patella Baja.

Project description:Patella baja is a severe complication seen after trauma, prolonged immobilization and surgery. Several surgical methods have been described to proximalize the patella without a change in the patella tendon length. Yet, patella tendon shortening and thickening can be regarded as the hallmark pathology. As such, we describe a technique for the lengthening of the patellar tendon to pathoconformly address underlying patella baja. The technique is reproducible and gives the possibility of an early postoperative mobilization to prevent re-baja-a typical complication after patella baja surgery.

Patellar Tendon Tenotomy for Treatment of Patella Baja and Extension Deficiency.

Project description:Extension loss due to patella baja is a rare but devastating postoperative complication associated with knee surgery. The most common causes of patella baja are prolonged postoperative immobilization, over-distalization of the patellar tendon during patella-related surgical procedures (i.e., tibial tubercle osteotomy and patellar tendon reconstruction), and inadequate knee range-of-motion exercises postoperatively. Patella baja can cause significant functional limitations owing to knee-related stiffness, pain, and weakness. Arthroscopy with scar tissue debridement is the standard of care for patients with arthrofibrosis in whom conservative treatment has failed. However, when this surgical approach fails, patients with continued patella baja may be candidates for open patellar tendon tenotomy as a salvage procedure.

Patellar Tendon Imbrication for Patella Alta.

Project description:Patella alta is a significant contributor to patellar instability. Historically, distalizing tibial tubercle osteotomy has been recommended for this problem; however, complications such as nonunion, fracture and hardware irritation are concerning. Additionally, the procedure cannot be performed on skeletally immature patients without violation of the proximal tibial physis. The authors describe a technique of patellar tendon imbrication that does not involve hardware or osteotomy. This technique allows for reliable correction of patella alta and provides patellar stability without the complications associated with osteotomy.

Does patellar eversion in total knee arthroplasty cause patella baja?

Project description:UNLABELLED: Several proponents of minimally invasive surgery-total knee arthroplasty (MIS-TKA) have suggested patellar eversion during a standard exposure of the knee may cause shortening of the patellar tendon and poorer outcomes secondary to acquired patella baja. To explore this suggestion, we retrospectively reviewed 135 consecutive TKAs in 110 patients to ascertain the effect of TKA on the postoperative Insall-Salvati ratio. All surgeries were performed using standard TKA techniques with a midline incision, medial parapatellar arthrotomy, partial excision of the fat pad, and routine eversion of the patella. One patient developed a postoperative patella baja, defined as an Insall-Salvati ratio of less than 0.8. The Knee Society score for knee and function in this patient was 75 and 70, respectively. Five additional patients had a decrease in Insall-Salvati ratio by 10% or more but without patella baja. Mean Knee Society score for knee and function in these five patients was 94 (range, 73-99) and 96 (range, 90-100), respectively, as compared with 93 (range, 37-99) and 94 (range, 40-100) in the remaining 104 patients. Our data suggest the incidence of patella baja is low after TKA despite routine patellar eversion. Furthermore, a 10% or more decrease in the Insall-Salvati ratio without patella baja was not associated with a worse clinical outcome. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Patellar Resurfacing Is Not a Risk Factor for Postoperative Patella Baja in Total Knee Arthroplasty.

Project description:BackgroundPatella baja is a known complication of total knee arthroplasty (TKA). There is a limited understanding of the association between patellar resurfacing and the incidence of patella baja. We aimed to compare rates of patella baja between unresurfaced and resurfaced patellas in patients undergoing TKA.MethodsA retrospective review of patients who underwent TKA between October 2009 and January 2020 was performed. Patients were included if they had at least one preoperative radiograph and a 1-year follow-up radiograph. Blackburne-Peel index (BPI) and Insall-Salvati ratios (ISRs) were measured on preoperative and 1-year postoperative radiographs and were used to define patella baja vs pseudopatella baja. Statistical analysis was performed using a linear model analysis of variance and the Fisher's exact test.ResultsThree hundred eighteen TKAs were included, with 176 being resurfaced and 142 unresurfaced patellas. Of the resurfaced group, 4% (7/176) had true patella baja, compared to 5.6% (8/142) of the unresurfaced patellas. Of the resurfaced patellas, 8% (14/176) had pseudopatella baja, compared to 7% (10/142) in the unresurfaced group. Patellar resurfacing was not associated with a higher incidence of patella baja (P = .60) or pseudopatella baja (P = .83). Lower preoperative ISRs (P = .04) and BPIs (0.03) were highly predictive of a higher incidence of patella baja post-TKA.ConclusionsPatellar resurfacing in TKA is not associated with a higher incidence of patella baja in TKA when compared to unresurfaced patellas. Lower preoperative ISRs and BPIs are highly predictive of a higher incidence of postoperative patella baja.

Patellar Tendon Shortening for Treatment of Patella Alta in Skeletally Immature Patients With Patellar Instability.

Project description:Aberrant anatomy, such as patella alta, can be a risk factor for recurrent patellar instability or inferior clinical outcomes after medial patellofemoral ligament reconstruction. In patients with significant patella alta (Caton Deschamps Index >1.2), tibial tubercle distalization may be considered to improve outcomes. However, despite patellar instability commonly affecting pediatric patients, a distalization osteotomy is not feasible in this patient population due to the presence of open physes. Our article presents a technique describing an alternative soft-tissue distalization approach whereby patellar height is decreased by shortening the patellar tendon.

Chronic Quadriceps Tendon Ruptures: Primary Repair of Quadriceps Via Bioaugmentation and Patellar Tendon Lengthening.

Project description:Quadriceps tendon ruptures are devastating injuries that impair the extensor mechanism of the knee. Complete tears require prompt surgical intervention in order to ensure optimal clinical outcomes. Chronic, neglected ruptures- marked by severe extensor lag, muscular atrophy, and tendon retraction- are difficult to treat. Further, severe patella baja complicates surgical planning. While there is no consensus on optimal treatment for these injuries, many different techniques have been proposed. Unlike many of these approaches, our technique focuses on restoration of patellar height via patellar tendon lengthening. Once patellar height is restored, quadriceps tendon repair can be performed using the native quadriceps tendon. Both the patellar tendon lengthening and the quadriceps tendon repair are augmented with bioinductive implants to ensure optimal healing environments, enabling us to reestablish native extensor mechanism function.

Technique for Fixation of Semitendinosus to the Patella in Patellar Tendon Reconstruction.

Project description:Chronic patellar tendon injuries are rare yet challenging to treat. Timing of surgery and graft choices are debatable. Many techniques and methods of fixation have been described with pros and cons. Functional impairment of the extensor mechanism and postoperative complications triggers the quest for finding the ideal technique. In this Technical Note, we use distally based semitendinosus (ST) looped over 2 ETHIBOND sutures. The ETHIBOND is passed through 2 vertical tunnels in the patella and retrieved proximally, docking the ST in a blind tunnel created in the lower pole of the patella. The whip-stitched free ST end is passed through a tunnel behind the tibial tubercle and sutured back to its base. A polyester tape is used to augment the repair in a circumferential manner. Postoperatively full weight bearing is allowed as tolerated in a hinged knee brace locked in extension with only passive range of motion of 0-90° allowed for 6 weeks.

Modified Elmslie-Trillat Procedure for Distal Realignment of Patella Tendon.

Project description:Patellofemoral dysfunction, due to either a patellofemoral malalignment or patellar instability, is a complex and debilitating condition that significantly decreases the knee function. Conservative management may yield significant clinical outcomes; however, when morphologic anomalies are identified, the surgical approach should be employed. Hence, several surgical procedures have been described in the scientific literature aiming the correction of underlying extensor mechanism malalignments. Still, the rate of complications is higher than desirable. The described technique is based on the principles of transferring the tibial tubercle medially as described in the Elmslie-Trillat technique. However, a curvilinear horizontal cut is made prior to the vertical cut, which raises a thick osseous fragment and allows the formation of a gutter when the osseous fragment is moved medially. Whereas the horizontal gutter provides stability to the bone fragment, the thicker dimension of the osseous fragment and retention of the distal attachment significantly enhances the osteotomy union. Hence, adequate pain relief and stability with very low postoperative morbidity could be achieved. The purpose of this surgical note is to describe a modification to the Elmslie-Trillat technique to treat patellofemoral dysfunctions, achieving a higher osseous stability and decreased postoperative morbidity.

Management of Neglected Patellar Tendon Rupture via the Ilizarov Apparatus and Patellar Transport Following Multistage Reconstruction using Contralateral Patella Tendon Bone Autograft: A Case Study.

Project description:Muscle elongation by Ilizarov apparatus is one of the most remarkable surgeries performed to date. Chronic patella tendon injury is an uncommon condition, and due to its rarity, it is difficult to operate and restore the quality of life and function of the patient. Here we demonstrated a 40-year-old Saudi person who underwent a three-stage operative procedure on him: in the first stage we entailed debridement and removal of the implant; in the second stage, we performed this innovative Ilizarov muscle elongation of the quadriceps, and in the third stage, we reconstructed the right patellar tendon using a contralateral patella tendon bone autograft fixed by 3.5 screws proximal to the patella and distal to the tibial tuberosity and augmented by cerclage wires. After 3 months of intensive physical therapy, the patient regained his knee's range of motion and muscle strength and was able to return to his security job.Graphical abstractSupplementary informationThe online version contains supplementary material available at 10.1007/s43465-022-00608-5.
