Low re-dislocation rate following Bereiter trochleoplasty for recurrent patellar instability with severe trochlear dysplasia.

Purpose: Trochlear dysplasia is an independent risk factor for recurrent patellar instability with evidence demonstrating its presence in up to 85% of patients with patellar instability. Severe trochlear dysplasia can be treated with trochleoplasty to improve engagement of the patella in the trochlear groove and prevent future dislocations. The aim of this study was to determine the clinical outcome of Bereiter trochleoplasty in patients with recurrent patellar instability and severe trochlear dysplasia.

Posterolateral Corner Reconstruction of the Knee Using Gracilis Autograft and Biceps Femoris.

We introduce our technique for posterolateral corner reconstruction, which is based on the principle described in Arciero's technique for anatomic reconstruction of lateral collateral ligament (LCL) and popliteofibular ligament (PFL) to gain static stability in varus strain and external rotation. This technique uses a doubled gracilis autograft to reconstruct the PFL and a split biceps tendon transfer to reconstruct the LCL. Using this technique an anatomical LCL and PFL reconstruction can be performed in combination with anterior cruciate ligament or posterior cruciate ligament reconstruction without contralateral graft harvest or allograft.

Excellent outcomes with combined single stage Physica ZUK medial unicompartment knee replacement and anterior cruciate ligament reconstruction results in young, active patients with instability and osteoarthritis with a mean follow up of 5 years.

Background (including The Aim Of The Study): Young and more active patients with medial compartment osteoarthritis (OA) in conjunction with anterior cruciate ligament (ACL) deficiency are difficult to treat. The aim of this study was to explore the outcomes of combined fixed bearing Physica ZUK medial unicompartmental knee replacement (UKR) (Lima Corporate, Udine Italy) with ACL reconstruction for patients presenting with isolated medial compartment OA and symptomatic ACL deficiency.

Methods: Patients who underwent simultaneous single stage ACL reconstruction and medial UKR between 2012 and 2020 by a single surgeon (GG) were included.

Management of mucoid degeneration of the anterior cruciate ligament: a systematic review.

Purpose: The purpose of this study was to investigate the outcomes of management of mucoid degeneration of the anterior cruciate ligament (MDACL) by performing a systematic review of methods of treatment that have been reported.

Methods: A systematic literature search in the databases MEDLINE, Embase, Google Scholar, Cochrane, ISI web of science and Scopus was performed through July 2020 by three independent reviewers. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and registered in the PROSPERO database (CRD42018087782).

Does additional reconstruction of the anterolateral ligament during a primary anterior cruciate ligament reconstruction affect tibial rotational laxity - A case series.

Background: The current evidence suggests that rotational stability in not restored in patients with anterior cruciate ligament (ACL) ruptures, despite reconstructive surgery. The graded pivot-shift is a useful clinical test to delineate extent of ligamentous laxity within the knee. Given its lateralised position, we hypothesized that reconstruction of the anterolateral ligament (ALL) would provide restraint to excessive internal rotation, restoring rotational stability.

Failure of meniscal repair association with late anterior cruciate ligament reconstruction.

Introduction: Meniscus injury is associated with ACL (anterior cruciate ligament) injury. It would be ideal to repair all meniscus tears but failure rate is high.

Aim: Our objective was to assess the success of meniscus repair.

All-inside meniscal repair surgery: factors affecting the outcome.

Background: Meniscal injury is currently a well-recognized source of knee dysfunction. While it would be ideal to repair all meniscus tears, the failure rate is significantly high, although it may be reduced by careful selection of the patients. Our objective was to assess the outcome of meniscal repair surgery and the role of simultaneous reconstruction of the anterior cruciate ligament (ACL).

Time delay between diagnosis and arthroscopic lavage in septic arthritis. Does it matter?

Purpose: Septic arthritis is a life-threatening emergency with high mortality of up to 11 %. We investigated if delay of arthroscopic lavage of infected major joints would have a bearing on the mortality and morbidity such as admission to an intensive care unit (ICU).

Methods: We retrospectively reviewed patients presenting with septic arthritis to two regional hospitals over a period of seven years from 1 January 2005 to 31 December 2011.

Hip extension strength following hamstring tendon harvest for ACL reconstruction.

Hamstring autograft harvest for ACL reconstruction may have an effect on hip extension strength and this may be important especially in sports that involve high speed running such as soccer, rugby, American football and the sprint disciplines of track and field. This aspect of hamstring tendon harvesting has not been looked at before. We have performed a non-randomised prospective case control study comparing isokinetic hip extension strength following four strand semitendinosus and gracilis tendons (4SHS) and bone-patellar tendon-bone (BPTB) autografts in ACL reconstruction.

Total knee arthroplasty after failed high tibial osteotomy long-term follow-up of matched groups.

Forty patients with 51 knee arthroplasties after high tibial osteotomy were compared with a matched group of patients with primary knee arthroplasties. Patients were matched according to length of follow-up, age, sex, prosthetic design, and surgeon. At an average of 12.

Arthroscopically assisted ACL reconstruction. Is a drain necessary?

We report on the results of a prospective randomised controlled trial to evaluate the use of an intra-articular drain following arthroscopically assisted ACL reconstruction using patellar tendon autograft. Forty-nine patients were recruited for the trial and randomised into receiving or not receiving a drain following surgery. An independent observer who was blinded for the use of the drain assessed the knees for swelling, range of movement (ROM) and pain at 2, 4 and 6 weeks postoperatively.
