The growing impact of fragility hip fracture (FHF) on the healthcare system and the society has become a major concern worldwide. A unified multidisciplinary FHF pathway from admission to rehabilitation and back to community was established in 2015. The acute phase of the pathway was put into pilot in our hospital to evaluate the outcome.

A designated FHF team was established in our centre since January 2015. The FHF pathway was piloted since June 2015. Patients admitted with a hip fracture resulting from fall on standing height were included. Major outcome parameters were compared in three phases: (1) before FHF team and FHF pathway (January to December 2014), (2) after FHF team but before FHF pathway (January to May 2015) and (3) after FHF team and FHF pathway (June 2015 to May 2016).

In phases 1, 2 and 3, 631, 263 and 634 patients were included, respectively. From phases 1 to 3, the average key performance indicator (KPI) has improved from 49.2% to 65.8% to 70.0% significantly; average acute length of stay (days) has improved from 13.7 to 13.4 to 11.3 significantly; total surgical complication rates have improved from 6.2% to 7.6% to 5.8%. The 30-day mortality rate and the unplanned readmission rate (within 28 days) have remained below 2.7% and 2.2%, respectively.

Implementation of an FHF pathway can form a multidisciplinary platform that can improve the standard of care and outcome for our FHF patients in terms of KPI and also length of stay.

A newly designed and implemented fragility hip fracture pathway in our centre as a pilot with the results evaluated.

With the increasing elderly population in Hong Kong and globally, there is a need to design and implement a fragility hip fracture (FHF) pathway to improve the care and effectiveness for FHF patients.

Partial knee replacement (PKR) is one of the treatment options in middle-aged patients with less extensive knee osteoarthritis, with unicompartmental knee replacement (UKR) most commonly done for medial osteoarthritis. There are numerous advantages like bone/ligament preserving and faster recovery. However, the indications of UKR remain controversial, as most patients have some patellofemoral joint (PFJ) osteoarthritis. We performed modular bicruciate-retaining bicompartmental knee replacement (BKR) in this group of patients and compared the outcome with total knee replacement (TKR).

From 2016 to 2017, 14 BKR were performed in patients with medial and PFJ osteoarthritis. They were retrospectively compared with 14 TKR performed in patients with similar age and severity. The incision length, operative time, blood loss (in terms of hemoglobin drop), and length of stay were recorded. Pre- and postoperative range of motion and Knee Society knee score at 1-year follow-up were compared.

The mean incision length for BKR was shorter than TKR (130.1 vs. 185.1 mm), but the mean operative time was also longer (152.6 vs. 88.1 min). There was also less mean hemoglobin drop (1.8 vs. 2.6 g/dL) and shorter length of stay (7.4 vs. 9.2 days). The mean postoperative function score is better in BKR group (90.4 vs. 77.5), and the mean postoperative knee score (87.2 vs 88.9) and flexion (115.7° vs. 111.4°) were similar for both groups.

In selected patients, BKR is a good alternative to TKR. It preserves advantages of UKR while also tackle the PFJ which is the most controversial aspect of UKR. The early clinical outcome in our study is promising. However, there is a learning curve. Longer follow-up is necessary to study on the performance and survivorship as compared with UKR and TKR.

Minimal invasive Achilles tendon repair is becoming more and more popular recently. We have evaluated our results in Achilles tendon repair using minimally invasive method by a suture-guiding device.

This is a retrospective review of patients with acute Achilles tendon rupture, which was repaired using minimally invasive method namely the suture-guiding device, that was performed during 2003 to 2015 in our department. Outcome parameters were the incidence of re-rupture, other complications, and the functional outcome.

There were 36 men (90%) and 4 women (10%) in this study. Mechanisms of injury were basketball (28%), football (15%), squash (15%), and trauma (13%). The mean operating time was 59 min (range 30–90 min). The mean follow-up time was 8 months (range 3–35 months). The mean duration with casting was 7 weeks. The mean range of movement at 3 months was 8° dorsiflexion and 33° plantar flexion. There was no major complication necessitating surgical re-interventions such as re-ruptures and infections. No patient suffered from dysfunction of the sural nerve or delay wound healing.

Minimally invasive Achilles tendon repair using suture-guiding device is a safe and quick procedure with a low rate of re-rupture and a satisfactory short-term and long-term recovery.
